January 2026 Recap: Azure Database for PostgreSQL
Hello Azure Community, We’re kicking off the year with important updates for Azure Database for PostgreSQL. From Premium SSD v2 features now available in public preview to REST API feature updates across developer tools, this blog highlights what’s new and what’s coming. Terraform Adds Support for PostgreSQL 18 – Generally Available Ansible module update - Generally Available Achieving Zonal Resiliency with Azure CLI - Generally Available SDKs Released : Go, Java, JavaScript, .NET and Python – Generally Available What’s New in Premium SSD v2 - Public Preview Latest PostgreSQL minor versions January 2026 Maintenance Release Notes Terraform Adds Support for PostgreSQL 18 Azure Database for PostgreSQL now provides support for PostgreSQL 18 which allows customers to create new servers with PostgreSQL 18 version and upgrade existing ones using Terraform. This update makes it easier to adopt PostgreSQL 18 on Azure while managing both provisioning and upgrades through consistent Terraform workflows. Learn more about using the new terraform resource Ansible Module Update A new Ansible module is now available with support for the latest GA REST API features, enabling customers to automate provisioning and management of Azure Database for PostgreSQL resources. This includes support for Elastic Clusters provisioning, deployment of PostgreSQL instances with PostgreSQL 18, and broader adoption of newly released Azure Database for PostgreSQL capabilities through Ansible. Learn more about using Ansible module with latest REST API features Achieve zonal resiliency with Azure CLI We have released updates to the Azure CLI that allow users to enable zone‑redundant high availability (HA) by default using a new --zonal-resiliency parameter. This parameter can be set to enabled or disabled. When --zonal-resiliency is enabled, the service provisions a standby server in a different availability zone than the primary, providing protection against zonal failures. If zonal capacity is not available in the selected region, you can use the --allow-same-zone flag to provision the standby in the same zone as the primary. Azure CLI commands: az postgres flexible-server update --resource-group <resource_group> --name <server> --zonal-resiliency enabled --allow-same-zone</server></resource_group> az postgres flexible-server update --resource-group <resource_group> --name <server> --zonal-resiliency Disabled</server></resource_group> az postgres flexible-server create --resource-group <resource_group> --name <server> --zonal-resiliency enabled --allow-same-zone</server></resource_group> Learn more about how to configure high availability on Azure Database for PostgreSQL. SDKs Released : Go, Java, JavaScript, .NET and Python We have released updated SDKs for Go, Java, JavaScript, .NET, and Python, built on the latest GA REST API (2025‑08‑01). These SDKs enable developers to programmatically provision, configure, and manage Azure Database for PostgreSQL resources using stable, production‑ready APIs. It also adds the ability to set a default database name for Elastic Clusters, simplifying cluster provisioning workflows, support for PostgreSQL 18. To improve developer experience and reliability, operation IDs have been renamed for clearer navigation, and HTTP response codes have been corrected so automation scripts and retries behave as expected. Learn More about .NET SDK Learn more about Go SDK Learn more about Java SDK Learn more about Javascript SDK Learn more about Python SDK What’s New in Premium SSD v2: Public Preview Azure Database for PostgreSQL Flexible Server now supports a broader set of resiliency and lifecycle management capabilities on Premium SSD v2, enabling production‑grade PostgreSQL deployments with improved durability, availability, and operational flexibility. In this preview, customers can use High Availability (same‑zone and zone‑redundant), geo‑redundant backups, in‑region and geo read replicas, geo‑disaster recovery (Geo‑DR), and Major Version Upgrades on SSDv2‑backed servers, providing both zonal and regional resiliency options for mission‑critical PostgreSQL workloads. These capabilities help protect data across availability zones and regions, support compliance and disaster‑recovery requirements, and simplify database lifecycle operations. Premium SSD v2 enhances these resiliency workflows with higher and independently scalable IOPS and throughput, predictable low latency, and decoupled scaling of performance and capacity. Customers can provision and adjust storage performance without over‑allocating disk size, enabling more efficient capacity planning while sustaining high‑throughput, low‑latency workloads. When combined with zone‑resilient HA and cross‑region data protection, SSDv2 provides a consistent storage foundation for PostgreSQL upgrades, failover, backup, and recovery scenarios. These capabilities are being expanded incrementally across regions as the service progresses toward general availability For more details, see Premium SSDv2 Latest Postgres minor versions: 18.1, 17.7, 16.11, 15.15, 14.20, 13.23 Azure Database for PostgreSQL now supports the latest PostgreSQL minor versions: 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23. These updates are applied automatically during planned maintenance windows, ensuring your databases stay up to date with critical security fixes and reliability improvements no manual action required. This release includes two security fixes and over 50 bug fixes across indexing, replication, partitioning, memory handling, and more. PostgreSQL 13.23 is the final community release for version 13, which has now reached end-of-life (EOL).

Azure Postgres Learning Bytes Managing Replication Lag with Debezium Change Data Capture (CDC) enables real‑time integrations by streaming row‑level changes from OLTP systems like PostgreSQL into event streams, data lakes, caches, and microservices. In a typical CDC pipeline, Debezium captures changes from PostgreSQL and streams them into Kafka with minimal latency. However, during large bulk updates that affect millions of rows, replication lag can spike significantly, impacting replication lag. This learning byte walks through how to detect and mitigate replication lag in Azure Database for PostgreSQL when using Debezium. Detect Replication Lag: Start by identifying where lag is building up in the system. Monitor replication slots and lag: Use the following query to inspect active replication slots and measure how far behind they are relative to the current WAL position: SELECT slot_name, active_pid, confirmed_flush_lsn, restart_lsn, pg_current_wal_lsn(), pg_size_pretty( ( pg_current_wal_lsn() - confirmed_flush_lsn ) ) AS lsn_distance FROM pg_replication_slots; Check WAL sender backend status: Verify whether WAL sender processes are stalled due to decoding or I/O waits: SELECT pid, backend_type, application_name, wait_event FROM pg_stat_activity WHERE backend_type = 'walsender' ORDER BY backend_start; Inspect spill activity : High spill activity indicates memory pressure during logical decoding and may contribute to lag. Large values for spill_bytes or spill_count suggest the need to increase logical_decoding_work_mem, reduce transaction sizes, or tune Debezium connector throughput. SELECT slot_name, spill_txns, spill_count, pg_size_pretty(spill_bytes) AS spill_bytes, total_txns, pg_size_pretty(total_bytes) AS total_bytes, stats_reset FROM pg_stat_replication_slots; Fix Replication Lag: Database and infrastructure tuning Reduce unnecessary overhead and ensure compute, memory, and storage resources are appropriately scaled to handle peak workloads. Connector level tuning Adjust Debezium configuration to keep pace with PostgreSQL WAL generation and Kafka throughput. This includes tuning batch sizes, poll intervals, and throughput settings to balance latency and stability.

Terraform on Azure Product GroupAnnouncing MSGraph Provider Public Preview and the Microsoft Terraform VSCode Extension
We are thrilled to announce two exciting developments in the Microsoft ecosystem for Terraform infrastructure-as-code (IaC) practitioners: the public preview of the Terraform Microsoft Graph (MSGraph) provider and the release of the Microsoft Terraform Visual Studio Code (VSCode) extension. These innovations are designed to streamline your workflow, empower your automation, and make managing Microsoft cloud resources easier than ever. Public Preview: Terraform Microsoft Graph (MSGraph) Provider The Terraform MSGraph provider empowers you to manage Entra APIs like privileged identity management as well as M365 Graph APIs like SharePoint sites from day 0 by leveraging the power and flexibility of HashiCorp Configuration Language (HCL) in Terraform. resource "msgraph_resource" "application" { url = "applications" body = { displayName = "My Application" } response_export_values = { all = "@" app_id = "appId" } } output "app_id" { value = msgraph_resource.application.output.app_id } output "all" { // it will output the whole response value = msgraph_resource.application.output.all } Historically, Terraform users could utilize the `azuread` provider to manage Entra features like users, groups, service principals, and applications. The new `msgraph` provider also supports these features and extends functionality to all beta and v1 Microsoft Graph endpoints. Querying role assignments for a service principal The below example shows how to use the `msgraph` provider to grant app permissions to a service principal: locals { MicrosoftGraphAppId = "00000003-0000-0000-c000-000000000000" # AppRoleAssignment userReadAllAppRoleId = one([for role in data.msgraph_resource.servicePrincipal_msgraph.output.all.value[0].appRoles : role.id if role.value == "User.Read.All"]) userReadWriteRoleId = one([for role in data.msgraph_resource.servicePrincipal_msgraph.output.all.value[0].oauth2PermissionScopes : role.id if role.value == "User.ReadWrite"]) # ServicePrincipal MSGraphServicePrincipalId = data.msgraph_resource.servicePrincipal_msgraph.output.all.value[0].id TestApplicationServicePrincipalId = msgraph_resource.servicePrincipal_application.output.all.id } data "msgraph_resource" "servicePrincipal_msgraph" { url = "servicePrincipals" query_parameters = { "$filter" = ["appId eq '${local.MicrosoftGraphAppId}'"] } response_export_values = { all = "@" } } resource "msgraph_resource" "application" { url = "applications" body = { displayName = "My Application" requiredResourceAccess = [ { resourceAppId = local.MicrosoftGraphAppId resourceAccess = [ { id = local.userReadAllAppRoleId type = "Scope" }, { id = local.userReadWriteRoleId type = "Scope" } ] } ] } response_export_values = { appId = "appId" } } resource "msgraph_resource" "servicePrincipal_application" { url = "servicePrincipals" body = { appId = msgraph_resource.application.output.appId } response_export_values = { all = "@" } } resource "msgraph_resource" "appRoleAssignment" { url = "servicePrincipals/${local.MSGraphServicePrincipalId}/appRoleAssignments" body = { appRoleId = local.userReadAllAppRoleId principalId = local.TestApplicationServicePrincipalId resourceId = local.MSGraphServicePrincipalId } } SharePoint & Outlook Notifications With your service principals properly configured, you can set up M365 endpoint workflows such an outlook notification template list as shown below. The actual service principal setup has been omitted from this code sample for the sake of brevity, but you will need Sites.Manage.All, Sites.ReadWrite.All, User.Read, and User.Read.All permissions for this example to work: data "msgraph_resource" "sharepoint_site_by_path" { url = "sites/microsoft.sharepoint.com:/sites/msgraphtest:" response_export_values = { full_response = "@" site_id = "id || ''" } } resource "msgraph_resource" "notification_templates_list" { url = "sites/${msgraph_resource.sharepoint_site_by_path.output.site_id}/lists" body = { displayName = "DevOps Notification Templates" description = "Centrally managed email templates for DevOps automation" template = "genericList" columns = [ { name = "TemplateName" text = { allowMultipleLines = false appendChangesToExistingText = false linesForEditing = 1 maxLength = 255 } }, { name = "Subject" text = { allowMultipleLines = false appendChangesToExistingText = false linesForEditing = 1 maxLength = 500 } }, { name = "HtmlBody" text = { allowMultipleLines = true appendChangesToExistingText = false linesForEditing = 10 maxLength = 10000 } }, { name = "Recipients" text = { allowMultipleLines = true appendChangesToExistingText = false linesForEditing = 3 maxLength = 1000 } }, { name = "TriggerConditions" text = { allowMultipleLines = true appendChangesToExistingText = false linesForEditing = 5 maxLength = 2000 } } ] } response_export_values = { list_id = "id" list_name = "displayName" web_url = "webUrl" } } The MSGraph provider is to AzureAD as the AzAPI provider is to AzureRM. Since support for resource types is automatic, you can access the latest features and functionality as soon as they're released via the provider. AzureAD will continue to serve as the convenience layer implementation of a subset of Entra APIs. We invite you to try the new provider today: - Deploy your first msgraph resources - Check out the registry page - Visit the provider GitHub Introducing the Microsoft Terraform VSCode Extension The new official Microsoft Terraform extension for Visual Studio Code consolidates AzureRM, AzAPI, and MSGraph VSCode support into a single powerful extension. The extension supports exporting Azure resources as Terraform code, as well as IntelliSense, syntax highlighting, and code sample generation. It replaces the Azure Terraform and AzAPI VSCode extensions and adds some new features. Installation & Migration New users can install the extension by searching “Microsoft Terraform” within Visual Studio Marketplace or their “Extensions” tab. Users can also click this link to the Visual Studio marketplace. Users of the “Azure Terraform” extension can navigate to “Extensions” tab and selecting the old extension. Select the “Migrate” button to move to the new extension. Users of the “Terraform AzAPI Provider” extension will be directed to the new extension: New Features Export Azure Resources As Terraform This feature allows you to export existing Azure resources as Terraform configuration blocks using Azure Export for Terraform. This helps you migrate existing Azure resources to Terraform-managed infrastructure. Open the Command Palette (Command+Shift+P on macOS and Ctrl+Shift+P on Windows/Linux). Search for and select the command Microsoft Terraform: Export Azure Resource as Terraform. Follow the prompts to select the Azure subscription and resource group containing the resources you want to export. Select the azurerm provider or the azapi provider to export the resources. The extension will generate the Terraform configuration blocks for the selected resources and display them in a new editor tab. Support for MSGraph The new extension comes fully equipped with intellisense, code completion, and code samples just like the AzAPI provider. See the next section for recorded examples of these features within the AzureRM & AzAPI providers. Preexisting Features Intelligent Code Completion: Benefit from context-aware suggestions, like property names or resource types. Code Samples: Quickly insert code samples for your resources: Paste as AzAPI: Copy your existing resource JSON or ARM Templates into VSCode with the Microsoft Terraform extension, and it will automatically convert your code into AzAPI. The below example takes a resource JSON from the Azure Portal and pastes it into VSCode as AzAPI: Migrate AzureRM to AzAPI: Move existing AzureRM code to the AzAPI provider whenever you wish to. Read more in the Guide to migrate AzureRM resources to AzAPI Feedback We value your feedback! You can share your experience with the Microsoft Terraform extension by running the command Microsoft Terraform: Show Survey from the Command Palette. Your input helps us improve the extension and better serve your needs. Conclusion Whether you are managing traditional Azure resources, modern Microsoft Graph environments, or a combination of both, the new MSGraph provider and Microsoft Terraform VS Code extension are designed to help you deliver robust, reliable infrastructure—faster and with greater confidence. Stay tuned for further updates, workshops, and community events as we continue to evolve these offerings. Your feedback and participation are invaluable as we build the next generation of infrastructure automation together.Terraform Azure Verified Modules for Platform Landing Zone (ALZ) Migration Guidance and Tooling
We are very pleased to announce that migration guidance and tooling to aid Terraform import is now moving from public preview to being generally available. Where to find it Head over to aka.ms/alz/tf/migrate to read our guidance and find our tooling. What does it do The migration guidance talks you through the procedure to migrate Terraform state from the classic CAF Enterprise Scale module to the Terraform Azure Verified Modules for Platform Landing Zone (ALZ) modules. The guidance and tooling helps you generate a set of Terraform import blocks to import the state of your existing platform landing zones into the Azure Verified Modules (AVM). Once those blocks have been generated, you can raise a pull request, test and merge then apply with your continuous delivery tool to import the state. From there forwards, you will be managing the platform landing zone with the AVM. How does it work The migration tool aids in mapping your deployed Microsoft Azure resources against the Azure Verified Modules. It maps on name or other available attributes. The tool follows a 3 stage process: Setup Resource Mapping Resource Attribute Mapping Setup This stage involves you configuring the target Terraform module by using the ALZ IaC Accelerator or composing your own module for advanced use cases. You will also need to identify your existing management group hierarchy and platform subscriptions in this stage. Resource Mapping During this stage you will run the migration tool. The tool will attempt to match all resources in the target subscriptions and / or management groups against the Azure Verified Module planned resources. For anything it can't match on, it will provide details in a file called issues.csv. You'll review issues.csv and correct any resource names in the target module to ensure they match your existing resource names. You'll then run the tool again and repeat until you have matched everything you can. We provide example tfvars files and lib folder to make this easier, they are commented with things you'll likely need to change. Once you have updated all the names you can, if you still have any issues left in issues.csv, you'll need to specify what you want to do with them. You can either: Ignore them Destroy and Recreate them Destroy them You'll add the action against each row in the CSV and then save the CSV file as resolved-issues.csv ready for the next stage. Resource Attribute Mapping Now you've mapped the resources themselves, you'll need to check that the attributes of the resources also match your existing configuration where they need to. To help with this you'll run the tool again, this time supplying your resolved-issues.csv as an input. This will prompt the tool to generate the Terraform import blocks and run a Terraform plan. The tool outputs a simplified plan file that only includes the changes you need to care about, namely update and destroy and recreate. You'll review the simplified plan file and determine if anything in there requires an update to your target module. If it does, you can update it and re-run the tool. You can repeat this until all unwanted changes are handled. You'll run the tool one last time to generate the final set of imports and now you are ready to apply the Terraform via your standard CI / CD process. Limitations At this time our guidance only supports resources that can be deployed by the classic CAF Enterprise Scale module. The tooling can technically support importing any resources, but we don't provide support or guidance for that scenario. The documentation of the tool for advanced scenarios is currently limited and we assume usage for this use case only at this time. Tooling This migration guidance uses a generic tool called Terraform State Importer . This tool can be used to migrate state for any Azure Resource Manager Terraform resources to a new Terraform module. We provide specific configuration files and settings for this use case, but you could modify them for more advanced scenarios. The tool does not look at any existing module or Terraform state file, it directly queries Azure using KQL queries to identify your deployed resources, as such it could also be used to import resources deployed via ClickOps, ARM or Bicep too. Thanks Thanks to the following people for making this happen: Matt White and Jack Tracey for technical guidance and validation Paul Grimley and Charlie Grabiaud for keeping it on track Haflidi Fridthjofsson (Microsoft) and Aidan Hughes (Servent) for the comprehensive and very valuable testing and feedbackAzure Verified Modules: Support Statement & Target Response Times Update
We are announcing an update to the Azure Verified Modules (AVM) support statement. This change reflects our commitment to providing clarity alongside timely and effective support for our community and AVM module consumers. These changes are in preparation to allow us to enable AVM modules to be published as V1.X.X modules (future announcement on this soon 🥳 sign up to the next AVM Community Call on July 1st 2025 to learn more). What is the new support statement? You can find the support statement on the AVM website here: https://azure.github.io/Azure-Verified-Modules/help-support/module-support/#support-statements For bugs/security issues 5 business days for a triage, meaningful response, and ETA to be provided for fix/resolution by module owner (which could be past the 5 days) For issues that breach the 5 business days, the AVM core team will be notified and will attempt to respond to the issue within an additional 5 business days to assist in triage. For security issues, the Bicep or Terraform Product Groups may step in to resolve security issues, if unresolved, after a further additional 5 business days. For feature requests 15 business days for a meaningful response and initial triage to understand the feature request. An ETA may be provided by the module owner if possible. Key changes from the previous support statement In short its two items: Increasing response time targets from: 3 to 5 business days for issues And from 3 to 5 business days for AVM core team escalation Handling bugs/security issues separately from feature requests Feature requests now have a 15 business day target response time The previous support statement outlined a more rigid structure for issue triage and resolution. It required module owners/contributors to respond within 3 business days, with the AVM core team stepping in if there was no response within a further 24 hours. In the event of a security issue being unaddressed after 5 business days, escalation to the product group (Bicep/Terraform) would occur to assist the AVM core team. There was also no differentiation between bugs/security issues and feature requests, which there now is. You can view the git diff of the support statement here Why the changes? Being honest, we weren't meeting the previous support statement 100% of the time, which we are striving for, across all the AVM modules. And we heard from you that, that wasn't ideal and we agree whole heartedly. Therefore, we took a step back, reflected, looked at the data available and huddled together to redefine what the new AVM support statement and targets should be. "Yeah, but why can't you just meet the previous support statement and targets?" This is a very valid question that you may have or be wondering. And we want to be honest with you so here are the reasons why this isn't possible today: Module owners are not 100% dedicated to only supporting their AVM modules; they also have other daily roles and responsibilities in their jobs at Microsoft. Sometimes this also means conflicting priorities for module owners and they have to make a priority call. We underestimated the impact of holidays, annual leave, public holidays etc. The AVM core teams responsibility is not to resolve all module issues/requests as they are smaller team driving the AVM framework, specs, tooling and tests. They will of course step in when needed, as they have done so far today 👍 We don't get as many contributions from the open-source community as we expected and would still love to see 😉 For clarity we always love to see a Pull Request to help us add new features or resolve bugs and issues, even for simple things like typos. It really does help us go faster 🏃➡️ "How are you going to try and avoid changing (increasing) the support statement and targets in the future?" Again another very valid ask! And we reflected upon this when making these changes to the support statement we are announcing here. To avoid this potential risk we are also taking the following actions today: Building new internal tooling and dashboards for module owners to discover, track and monitor their issues and pull requests across various modules they may own, across multiple languages. (already complete and published 👍) This tooling will also help the AVM core team track issues and report on them more easily to help module owners avoid non-compliance with the targets. Continue to push for, promote, and encourage open-source community contributions Prevent AVM modules being published as V1.X.X if they are unable to prove compliance with the new support statement and targets (sneak peek into V1.X.X requirements) Looking further into the future we are also investigating the following: Building a dedicated AVM team, separate from the AVM core team, that will triage, work on, and fix/resolve issues that are nearing or breaching the support statement and targets. Also they will look into feature requests as and where time allows or are popular/upvoted heavily where module owners are unable to prioritize in the near future due to other priorities. Seeing where AI and other automation tooling can assist with issue triage and resolution to reduce module owner workload. Summary We hope that this provides you with a clear understanding of the changes to the AVM support statement and targets and why we are making these. We also hope you appreciate our honesty on the situation and can see we are taking action to make things better while also reflecting and amending our support statements to be more realistic based on the past 2 years of launching and running AVM to date. Finally we just want to reassure everyone that we remain committed to AVM and have big plans for the rest of the calendar year and beyond! 😎 And with this in mind we want to remind you to sign up to the next AVM Community Call on July 1st 2025 to learn more and ask any questions on this topic or anything else AVM related with the rest of the community 👍 Thanks The AVM Core TeamApril 2025 Recap: Azure Database for PostgreSQL Flexible Server
Hello Azure Community, April has brought powerful capabilities to Azure Database for PostgreSQL flexible server, On-Demand backups are now Generally Available, a new Terraform version for our latest REST API has been released, the Public Preview of the MCP Server is now live, and there are also a few other updates that we are excited to share in this blog. Stay tuned as we dive into the details of these new features and how they can benefit you! Feature Highlights General Availability of On-Demand Backups Public Preview of Model Context Protocol (MCP) Server Additional Tuning Parameters in PG 17 Terraform resource released for latest REST API version General Availability of pg_cron extension in PG 17 General Availability of On-Demand Backups We are excited to announce General Availability of On-Demand backups for Azure Database for PostgreSQL flexible server. With this it becomes easier to streamline the process of backup management, including automated, scheduled storage volume snapshots encompassing the entire database instance and all associated transaction logs. On-demand backups provide you with the flexibility to initiate backups at any time, supplementing the existing scheduled backups. This capability is useful for scenarios such as application upgrades, schema modifications, or major version upgrades. For instance, before making schema changes, you can take a database backup, in an unlikely case, if you run into any issues, you can quickly restore (PITR) database back to a point before the schema changes were initiated. Similarly, during major version upgrades, on-demand backups provide a safety net, allowing you to revert to a previous state if anything goes wrong. In the absence of on-demand backup, the PITR could take much longer as it would need to take the last snapshot which could be 24 hours earlier and then replay the WAL. Azure Database for PostgreSQL flexible server already does on-demand backup behind the scenes for you and then deletes it when the upgrade is successful. Key Benefits: Immediate Backup Creation: Trigger full backups instantly. Cost Control: Delete on-demand backups when no longer needed. Improved Safety: Safeguard data before major changes or refreshes. Easy Access: Use via Azure Portal, CLI, ARM templates, or REST APIs. For more details and on how to get started, check out this announcement blog post. Create your first on-demand backup using the Azure portal or Azure CLI. Public Preview of Model Context Protocol (MCP) Server Model Context Protocol (MCP) is a new and emerging open protocol designed to integrate AI models with the environments where your data and tools reside in a scalable, standardized, and secure manner. We are excited to introduce the Public Preview of MCP Server for Azure Database for PostgreSQL flexible server which enables your AI applications and models to talk to your data hosted in Azure Database for PostgreSQL flexible servers according to the MCP standard. The MCP Server exposes a suite of tools including listing databases, tables, and schema information, reading and writing data, creating and dropping tables, listing Azure Database for PostgreSQL configurations, retrieving server parameter values, and more. You can either build custom AI apps and agents with MCP clients to invoke these capabilities or use AI tools like Claude Desktop and GitHub Copilot in Visual Studio Code to interact with your Azure PostgreSQL data simply by asking questions in plain English. For more details and demos on how to get started, check out this announcement blog post. Additional Tuning Parameters in PG17 We have now provided an expanded set of configuration parameters in Azure Database for PostgreSQL flexible server (V17) that allows you to modify and have greater control to optimize your database performance for unique workloads. You can now tune internal buffer settings like commit timestamp, multixact member and offset, notify, serializable, subtransaction, and transaction buffers, allowing you to better manage memory and concurrency in high-throughput environments. Additionally, you can also configure parallel append, plan cache mode, and event triggers that opens powerful optimization and automation opportunities for analytical workloads and custom logic execution. This gives you more control for memory intensive and high-concurrency applications, increased control over execution plans and allowing parallel execution of queries. To get started, all newly modifiable parameters are available now through the Azure portal, Azure CLI, and ARM templates, just like any other server configuration setting.

Azure Postgres Learning Bytes 🎓 Setting up alerts for Azure Database PostgreSQL flexible server using Terraform Monitoring metrics and setting up alerts for your Azure Database for PostgreSQL flexible server instance is crucial for maintaining optimal performance and troubleshooting workload issues. By configuring alerts, you can track key metrics like CPU usage and storage etc. and receive notifications by creating an action group for your alert metrics. This guide will walk you through the process of setting up alerts using Terraform. First, create an instance of Azure Database for PostgreSQL flexible server (if not already created) Next, create a Terraform File and add these resources 'azurerm_monitor_action_group', 'azurerm_monitor_metric_alert' as shown below. resource "azurerm_monitor_action_group" "example" { name = "<action-group-name>" resource_group_name = "<rg-name>" short_name = "<short-name>" email_receiver { name = "sendalerts" email_address = "<youremail>" use_common_alert_schema = true } } resource "azurerm_monitor_metric_alert" "example" { name = "<alert-name>" resource_group_name = "<rg-name>" scopes = [data.azurerm_postgresql_flexible_server.demo.id] description = "Alert when CPU usage is high" severity = 3 frequency = "PT5M" window_size = "PT5M" enabled = true criteria { metric_namespace = "Microsoft.DBforPostgreSQL/flexibleServers" metric_name = "cpu_percent" aggregation = "Average" operator = "GreaterThan" threshold = 80 } action { action_group_id = azurerm_monitor_action_group.example.id } } 3. Run the terraform initialize, plan and apply commands to create an action group and attach a metric to the Azure Database for PostgreSQL flexible server instance. terraform init -upgrade terraform plan -out <file-name> terraform apply <file-name>.tfplan Note: This script assumes you have already created an Azure Database for PostgreSQL flexible server instance. To verify your alert, check the Azure portal under Monitoring -> Alerts -> Alert Rules tab. Conclusion That's a wrap for the April 2025 feature updates!

Scenario Imagine you have an existing networking configuration you would like to bring to Terraform. Whether you’re interested in learning Terraform or an expert, understanding how Azure resources are reflected in the azurerm and azapi providers is critical to your team. With Terraform export, you can quickly see how your resources are represented in either provider, whether it’s one resource from the configuration or the entire resource group. Benefits Azure Export for Terraform is a tool designed to provide a seamless and efficient way to generate Terraform configuration files that accurately represent your Azure resources. With the new Portal experience, you can easily understand your infrastructure’s representation in either the AzureRM or AzAPI providers within Terraform. Usage Prerequisite Subscriptions will need to register the Microsoft.AzureTerraform resource provider. Portal Usage Find the experience in the Automation tab under the “Export template” blade. This experience is supported for individual resources as well as resource groups. Next Steps We invite you to try out the Azure Portal Export for Terraform feature and share your feedback with us via the Feedback button. Your input is valuable as we continue to improve and expand our offerings to better meet your needs. For scripting or exporting many resource groups or resource types, we encourage you to check out the Azure Export for Terraform tool, which comes with customization features. If you wish to utilize the underlying APIs directly or via CLI/PS, visit the new Azure Terraform resource provider documentation. As always, thank you for being a part of our Azure Terraform community and for your continued support.An Update on Bicep Azure Verified Modules for Platform Landing Zone (ALZ)
But first some history and context As you may of heard in one of our Azure Landing Zone (ALZ) community calls over the past year, across ALZ we have been working hard to refactor both our Terraform and Bicep implementation options to be built upon Azure Verified Modules (AVM). Earlier this year we announced that the work for Terraform, which we started on first, was complete; and you can read more about that in the announcement blog post we posted here. But whilst this work was going on the ALZ Bicep team where already busy planning how they would go about doing the same and rebuilding ALZ Bicep from AVM modules. You can see the original plans and where we also asked for feedback in the GitHub issue (#791) . Enough history, what's the latest? Now to answer the question everyone has and rightly so 😁 Well, it's good news! We have been busy working away on getting a number of the AVM Bicep Resource Modules updated with missing bits and pieces that we need from an ALZ perspective. All fairly minor in most cases but some required some bigger updates than others, and some modules didn't exist at all so we have had to propose, create, and publish those of which we are pretty much done with 👍 We are still working towards an end of Q4 (June/July) target for a preview release of all the modules, accelerator and guidance on how to use the new version of ALZ Bicep, which will be called "Bicep Azure Verified Modules for Platform Landing Zone (ALZ)"; this is to align with Terraform and also to provide clear distinction between ALZ Bicep and the new AVM based version. Please note that the timeline shared above is an ETA and may move Announcing the preview release of `avm/ptn/alz/empty` AVM Pattern Module Before we get to a more complete release of all the required resources and modules to build the entire ALZ architecture with the new Bicep Azure Verified Modules for Platform Landing Zone (ALZ), we wanted to share an early look at the module that will be at the heart of all of your ALZ deployments. That module is called `avm/ptn/alz/empty` and is available in the Public Bicep Registry for you to try out today (currently version `0.1.0`)! Tip: Checkout the "max" test in the tests directory for advanced usage examples! module testMg 'br/public:avm/ptn/alz/empty:0.1.0' = { params: { managementGroupName: 'test-mg' // Other parameters here... } } This module is 1 of 11 modules that will all be based off the same code. The module optionally creates all of the below: The Management Group itself Can also target an existing Management Group Management Group Subscription Associations RBAC Custom Role Definitions RBAC Role Assignments Policy Assignments Custom Policy Definitions Custom Policy Set Definitions (Initiatives) There will also be 1 x Bicep Azure Verified Modules for Platform Landing Zone (ALZ) pattern module for each of the ALZ Architectures Management Groups, plus this empty one for custom and advanced scenarios. A reminder of those Management Groups and the associated modules that will be created for each of them: `avm/ptn/alz/int-root` `avm/ptn/alz/platform` `avm/ptn/alz/platform-management` `avm/ptn/alz/platform-identity` `avm/ptn/alz/platform-connectivity` `avm/ptn/alz/landing-zones` `avm/ptn/alz/landing-zones-corp` `avm/ptn/alz/landing-zones-online` `avm/ptn/alz/decommissioned` `avm/ptn/alz/sandbox` These Management Group aligned pattern modules will create the same resources as above, but will have the latest release of the ALZ Library baked in to each of the modules. Meaning that for the `avm/ptn/alz/int-root` pattern module, you won't have to declare all of the ALZ RBAC Custom Role Definitions, Custom Policy Definitions, Policy Assignments etc. via the input parameters as they'll be hardcoded in the module based off the latest release from the ALZ Library at the point the version of the module was released. This means that to build the ALZ Management Group hierarchy and make all of the default ALZ policy assignments, as documented here, you'd need a bicep file that would look something like this as a starting point: Important: None of these modules exist below today! module intRootMg 'br/public:avm/ptn/alz/int-root:0.1.0' = { params: { managementGroupName: 'int-root-mg' } } module platformMg 'br/public:avm/ptn/alz/platform:0.1.0' = { params: { managementGroupName: 'platform-mg' managementGroupParentId: intRootMg.outputs.managementGroupId } } module platformConnectivityMg 'br/public:avm/ptn/alz/platform-connectivity:0.1.0' = { params: { managementGroupName: 'platform-mg' managementGroupParentId: platformMg.outputs.managementGroupId } } This will make getting the ALZ Architecture out of the box really fast, and also really easy to upgrade and get the latest updates, by just bumping the version number as you desire when you are ready. Coupled with the `avm/ptn/alz/empty` module to add your own additional Policy Definitions and assignments, etc. at the same Management Groups scopes also helps you decouple the constant updates to the ALZ architecture and policies etc. from your own additional requirements. Helping you keep your code cleaner and our modules simple to maintain as we won't have to cater for handling additional custom definitions and assignments alongside the defaults from ALZ that are baked into the modules. Note: We are looking at suggesting that all of these are deployed via Deployment Stacks to help with lifecycle management of resources. e.g. help clean-up resources as well as deploy new ones; think policy assignments and definitions etc. We need to complete a lot more testing on this, but would love your feedback on experiences if you have any using Deployment Stacks to manage these kind of resources today. Open an issue/discussion on the ALZ Bicep GitHub repo 👍 Our asks to you 🫵 Please go try out and test the new `avm/ptn/alz/empty` module and test it out for all the scenarios you can think of relating to Management Groups, RBAC, Policies etc. we want to make sure it's "match fit/ready" before we then build the Management Group aligned modules and bake in the ALZ defaults to them. So please go and put the module through its paces and test it out. Tip: Checkout the "max" test in the tests directory for advanced usage examples! If you find any issues, bugs, feature requests or just have a question on how to use it, please just raise them as GitHub issues here (make sure to select the `avm/ptn/alz/empty` module from the drop down 👍) Thanks in advance for all your efforts and assistance and we look forward to hearing and getting your feedback on the module 👏
