A Contained Availability Group (CAG) is designed to simplify high availability and disaster recovery by encapsulating system databases (master, msdb) within the availability group itself. This means that logins, jobs, credentials, and other metadata are automatically replicated across replicas, eliminating the need for manual synchronization and reducing operational complexity. Starting with SQL Server 2025 CU1, you can create or restore databases directly through the CAG listener - without connecting to the physical instance - by enabling a session context key or by using the automated stored procedure [msdb].[dbo].sp_sysutility_cag_create_db. Why Contained AGs Matter Self-contained HA unit: Each CAG has its own copy of master and msdb, making it independent of the physical SQL instance. Simplified failover: When the AG fails over, all associated metadata moves with it, ensuring applications continue to function without manual intervention. Improved automation: Supports scenarios where direct access to the SQL instance is restricted, enabling operations through the AG listener. Enhanced security: Reduces exposure by limiting instance-level access; operations can be scoped to the AG context. Streamlined management: Eliminates the need for login and job replication scripts across replicas. Step 1: Prepare the Database for Availability Group This example uses SQL Server on Linux; however, the steps are identical for SQL Server on Windows. In this walkthrough, an existing database named CAGDB is added to a Contained Availability Group (CAG). Before adding the database to the CAG, verify that it is configured for FULL recovery mode and perform a full database backup. ALTER DATABASE CAGDB SET RECOVERY FULL; GO BACKUP DATABASE CAGDB TO DISK = N'/var/opt/mssql/backups/CAGDB.bak' WITH INIT, COMPRESSION; GO Note: On Linux, ensure that the backup target directory exists and is owned by the mssql user. sudo mkdir -p /var/opt/mssql/backups sudo chown mssql:mssql /var/opt/mssql/backups Step 2: Create the Contained Availability Group On your Linux SQL Server nodes, run: CREATE AVAILABILITY GROUP [CAGDemo] WITH ( CLUSTER_TYPE = EXTERNAL, CONTAINED ) FOR DATABASE [CAGDB] REPLICA ON N'node1' WITH ( ENDPOINT_URL = N'tcp://node1:5022', AVAILABILITY_MODE = SYNCHRONOUS_COMMIT, FAILOVER_MODE = EXTERNAL, SEEDING_MODE = AUTOMATIC ), N'node2' WITH ( ENDPOINT_URL = N'tcp://node2:5022', AVAILABILITY_MODE = SYNCHRONOUS_COMMIT, FAILOVER_MODE = EXTERNAL, SEEDING_MODE = AUTOMATIC ); GO #Connect to secondary replicas and join the AG: ALTER AVAILABILITY GROUP [CAGDemo] JOIN WITH (CLUSTER_TYPE = EXTERNAL); ALTER AVAILABILITY GROUP [CAGDemo] GRANT CREATE ANY DATABASE; Step 3: Configure Listener and Connect Create a listener and connect using SSMS or sqlcmd: ALTER AVAILABILITY GROUP [CAGDemo] ADD LISTENER N'CAGDemoListener' ( WITH IP ( (N'*.*.*.*', N'255.255.255.0') ), PORT = 1453 ); GO Step 4: Connect to CAGDemoListener and attempt Database Creation (Failure) When connected through the listener: CREATE DATABASE TestCAGDB; Result:\ Msg 262, Level 14, State 1: CREATE DATABASE is not allowed in this context.\ This happens because database creation is blocked by default in a contained AG session. Step 5: Enable Database Creation in CAG Session or Instance master EXEC sp_set_session_context = N'allow_cag_create_db', @value = 1; This enables database creation for your current session. Step 5: Retry Database Creation (Success) CREATE DATABASE TestCAGDB; Result: Database created successfully within the contained AG context. Only users with dbcreator role in the CAG context can perform this action. Step 6: Backup the database. ALTER DATABASE TestCAGDB SET RECOVERY FULL; BACKUP DATABASE TestCAGDB TO DISK = N'/var/opt/mssql/data/backups/TestCAGDB.bak'; Step 7: Add database to the CAG ALTER AVAILABILITY GROUP [CAGDemo] ADD DATABASE [TestCAGDB]; Automation: To automate Steps 4 through 7, execute the following stored procedure while connected through the CAG Listener context. EXEC [msdb].[dbo].sp_sysutility_cag_create_db @database_name = [ADVENTUREWORKS]; Conclusion Contained Availability Groups represent a major step forward in simplifying high availability for SQL Server. By encapsulating system databases within the AG context, they eliminate the complexity of synchronizing logins, jobs, and credentials across replicas. With the new capability in SQL Server 2025 CU1 to create or restore databases directly through the AG listener using sp_set_session_context, organizations can streamline automation and reduce operational overhead. References What Is a Contained Availability Group Deploy a Pacemaker Cluster for SQL Server on LinuxAnnouncing GA of SQL Server 2025 on RHEL 10 and Ubuntu 24.04, with additional enhancements for Linux deployments
We are excited to announce the General Availability (GA) of SQL Server 2025 on Red Hat Enterprise Linux (RHEL) 10 and Ubuntu 24.04, starting with the CU1 release. This milestone empowers enterprises to deploy SQL Server 2025 on the latest Linux distributions, ensuring robust compatibility, enhanced security, and optimal performance for mission-critical workloads. The GA reinforces our commitment to delivering a modern, secure, and AI-ready database platform across diverse Linux environments. CU1 Release Highlights Key Features: Production-Ready Support: GA support for RHEL 10 and Ubuntu 24.04, enabling production deployments on the newest Linux platforms. Important: Update your SQL Server repository To ensure you are installing the production-ready GA version of SQL Server 2025, it is essential to update your repository from mssql-server-preview.repo to mssql-server-2025.repo. Continuing to use the preview repository may result in installing pre-release builds that are not intended for production workloads. You can proceed with the installation steps as described in the official documentation: RHEL: Install SQL Server on Linux Ubuntu: Install SQL Server on Linux Enable database creation or restoration in Contained Availability Group sessions You can now use the session context key 'allow_cag_create_db' set via the existing stored procedure sp_set_session_contex to enable database creation and restoration directly within a contained availability group (CAG) session through the CAG listener. Only users with the dbcreator role can create databases in a CAG session, and only users with the db_owner or sysadmin role can restore databases. Example: EXEC sp_set_session_context @key = N'allow_cag_create_db', @value = 1; This command enables the feature for your session. To disable it, set @value = 0. Enhanced Observability: SQL Server 2025 on Linux introduces new Dynamic Management Views (DMVs) that provides comprehensive, system-level insights. These DMVs collect and expose metrics from the underlying operating system, allowing administrators to monitor and diagnose not only SQL Server’s performance, but also the impact of other processes running on the same host. This holistic visibility helps distinguish between issues caused by SQL Server and those originating from other workloads or infrastructure bottlenecks, enabling more effective troubleshooting and optimization for mission-critical deployments. sys.dm_os_linux_cpu_stats: Enables users to identify CPU saturation, investigate I/O waits, analyze system responsiveness, and correlate SQL Server performance with broader OS activity, helping to separate database-specific bottlenecks from infrastructure-wide challenges. sys.dm_os_linux_disk_stats: Facilitates detection of log flush slowness, assessment of checkpoint or read-heavy workloads, and identification of external I/O pressure from noisy neighbors on shared hosts, helping teams optimize storage tiers and queue settings. sys.dm_os_linux_net_stats: Provides real-time visibility into network interface statistics, enabling proactive monitoring and troubleshooting of connectivity and throughput issues. Collectively, these DMVs equip database professionals with actionable, OS-level metrics to maintain stability, optimize performance, and ensure reliability in mission-critical Linux deployments.

Run a SQL Query with Azure Arc
Hi All, In this article, you can find a way to retrieve database permission from all your onboarded databases through Azure Arc. This idea is born from a customer request around maintaining a standard permission set, in a very wide environment (about 1000 SQL Server). This solution is based on Azure Arc, so first you need to onboard your SQL Server to Azure Arc and enable the SQL Server extension. If you want to test Azure Arc in a test environment, you can use the Azure Jumpstart, in this repo you will find ready-to-deploy arm templates the deploy demos environments. The other solution components are an automation account, log analytics and a Data collection rule \ endpoint. Here you can find a little recap of the purpose of each component: Automation account: with this resource you can run and schedule a PowerShell script, and you can also store the credentials securely Log Analytics workspace: here you will create a custom table and store all the data that comes from the script Data collection Endpoint / Data Collection Rule: enable you to open a public endpoint to allow you to ingest collected data on Log analytics workspace In this section you will discover how I composed the six phases of the script: Obtain the bearer token and authenticate on the portal: First of all you need to authenticate on the azure portal to get all the SQL instance and to have to token to send your assessment data to log analytics $tenantId = "XXXXXXXXXXXXXXXXXXXXXXXXXXX" $cred = Get-AutomationPSCredential -Name 'appreg' Connect-AzAccount -ServicePrincipal -Tenant $tenantId -Credential $cred $appId = $cred.UserName $appSecret = $cred.GetNetworkCredential().Password $endpoint_uri = "https://sampleazuremonitorworkspace-weu-a5x6.westeurope-1.ingest.monitor.azure.com" #Logs ingestion URI for the DCR $dcrImmutableId = "dcr-sample2b9f0b27caf54b73bdbd8fa15908238799" #the immutableId property of the DCR object $streamName = "Custom-MyTable" $scope= [System.Web.HttpUtility]::UrlEncode("https://monitor.azure.com//.default") $body = "client_id=$appId&scope=$scope&client_secret=$appSecret&grant_type=client_credentials"; $headers = @{"Content-Type"="application/x-www-form-urlencoded"}; $uri = "https://login.microsoftonline.com/$tenantId/oauth2/v2.0/token" $bearerToken = (Invoke-RestMethod -Uri $uri -Method "Post" -Body $body -Headers $headers).access_token Get all the SQL instances: in my example I took all the instances, you can also use a tag to filter some resources, for example if a want to assess only the production environment you can use the tag as a filter $servers = Get-AzResource -ResourceType "Microsoft.AzureArcData/SQLServerInstances" When you have all the SQL instance you can run your t-query to obtain all the permission , remember now we are looking for the permission, but you can use for any query you want or in other situation where you need to run a command on a generic server $SQLCmd = @' Invoke-SQLcmd -ServerInstance . -Query "USE master; BEGIN IF LEFT(CAST(Serverproperty('ProductVersion') AS VARCHAR(1)),1) = '8' begin IF EXISTS (SELECT TOP 1 * FROM tempdb.dbo.sysobjects (nolock) WHERE name LIKE '#TUser%') begin DROP TABLE #TUser end end ELSE begin IF EXISTS (SELECT TOP 1 * FROM tempdb.sys.objects (nolock) WHERE name LIKE '#TUser%') begin DROP TABLE #TUser end end CREATE TABLE #TUser (DBName SYSNAME,[Name] SYSNAME,GroupName SYSNAME NULL,LoginName SYSNAME NULL,default_database_name SYSNAME NULL,default_schema_name VARCHAR(256) NULL,Principal_id INT); IF LEFT(CAST(Serverproperty('ProductVersion') AS VARCHAR(1)),1) = '8' INSERT INTO #TUser EXEC sp_MSForEachdb ' SELECT ''?'' as DBName, u.name As UserName, CASE WHEN (r.uid IS NULL) THEN ''public'' ELSE r.name END AS GroupName, l.name AS LoginName, NULL AS Default_db_Name, NULL as default_Schema_name, u.uid FROM [?].dbo.sysUsers u LEFT JOIN ([?].dbo.sysMembers m JOIN [?].dbo.sysUsers r ON m.groupuid = r.uid) ON m.memberuid = u.uid LEFT JOIN dbo.sysLogins l ON u.sid = l.sid WHERE (u.islogin = 1 OR u.isntname = 1 OR u.isntgroup = 1) and u.name not in (''public'',''dbo'',''guest'') ORDER BY u.name ' ELSE INSERT INTO #TUser EXEC sp_MSforeachdb ' SELECT ''?'', u.name, CASE WHEN (r.principal_id IS NULL) THEN ''public'' ELSE r.name END GroupName, l.name LoginName, l.default_database_name, u.default_schema_name, u.principal_id FROM [?].sys.database_principals u LEFT JOIN ([?].sys.database_role_members m JOIN [?].sys.database_principals r ON m.role_principal_id = r.principal_id) ON m.member_principal_id = u.principal_id LEFT JOIN [?].sys.server_principals l ON u.sid = l.sid WHERE u.TYPE <> ''R'' and u.TYPE <> ''S'' and u.name not in (''public'',''dbo'',''guest'') order by u.name '; SELECT DBName, Name, GroupName,LoginName FROM #TUser where Name not in ('information_schema') and GroupName not in ('public') ORDER BY DBName,[Name],GroupName; DROP TABLE #TUser; END" '@ $command = New-AzConnectedMachineRunCommand -ResourceGroupName "test_query" -MachineName $server1 -Location "westeurope" -RunCommandName "RunCommandName" -SourceScript $SQLCmd In a second, you will receive the output of the command, and you must send it to the log analytics workspace (aka LAW). In this phase, you can also review the output before sending it to LAW, for example, removing some text or filtering some results. In my case, I’m adding the information about the server where the script runs to each record. $array = ($command.InstanceViewOutput -split "r?n" | Where-Object { $.Trim() }) | ForEach-Object { $line = $ -replace '\', '\\' ù$array = $array | Where-Object { $_ -notmatch "DBName,Name,GroupName,LoginName" } | Where-Object {$_ -notmatch "------"} The last phase is designed to send the output to the log analytics workspace using the dce \ dcr. $staticData = @" [{ "TimeGenerated": "$currentTime", "RawData": "$raw", }]"@; $body = $staticData; $headers = @{"Authorization"="Bearer $bearerToken";"Content-Type"="application/json"}; $uri = "$endpoint_uri/dataCollectionRules/$dcrImmutableId/streams/$($streamName)?api-version=2023-01-01" $rest = Invoke-RestMethod -Uri $uri -Method "Post" -Body $body -Headers $headers When the data arrives in log analytics workspace, you can query this data, and you can create a dashboard or why not an alert. Now you will see how you can implement this solution. For the log analytics, dce and dcr, you can follow the official docs: Tutorial: Send data to Azure Monitor Logs with Logs ingestion API (Resource Manager templates) - Azure Monitor | Microsoft Learn After you create the dcr and the log analytics workspace with its custom table. You can proceed with the Automation account. Create an automation account using the creating wizard You can proceed with the default parameter. When the Automation Account creation is completed, you can create a credential in the Automation Account. This allows you to avoid the exposition of the credential used to connect to Azure You can insert here the enterprise application and the key. Now you are ready to create the runbook (basically the script that we will schedule) You can give the name you want and click create. Now go in the automation account than Runbooks and Edit in Portal, you can copy your script or the script in this link. Remember to replace your tenant ID, you will find in Entra ID section and the Enterprise application You can test it using the Test Pane function and when you are ready you can Publish and link a schedule, for example daily at 5am. Remember, today we talked about database permissions, but the scenarios are endless: checking a requirement, deploying a small fix, or removing/adding a configuration — at scale. At the end, as you see, Azure Arc is not only another agent, is a chance to empower every environment (and every other cloud provider 😉) with Azure technology. See you in the next techie adventure. **Disclaimer** The sample scripts are not supported under any Microsoft standard support program or service.

GitHub Copilot + SQL Server: Understanding the Security Analyzer
What problem is this trying to solve? Many security issues in applications come from the database layer: poorly written queries, dynamic SQL, or code that exposes more data than it should. These problems are often hard to spot, especially in large or older codebases. The MSSQL extension for VS Code (v1.37+) now integrates GitHub Copilot with a dedicated chat participant: mssql. One of its most useful capabilities is the Security Analyzer, which reviews your T-SQL code and highlights potential security weaknesses. This is not just a generic AI model reading text. The tool connects to your SQL Server or Azure SQL database and uses the real context of your environment: your schema, tables, views, and stored procedures. That context allows it to give much more precise and relevant guidance. Where does it work? The Security Analyzer supports: • SQL Server 2019, 2022, 2025 (Windows, Linux, containers) • Azure SQL Database • Azure SQL Managed Instance • SQL database in Fabric If you run a mix of on-premises, cloud, or older environments, you can still use the same tool and interface across them. What can the Security Analyzer do? Based on the official documentation and early testing, typical use cases include: 1️⃣ Detecting SQL injection risks It reviews stored procedures and queries to find unsafe dynamic SQL, string concatenations used to build queries, or risky use of EXEC. These patterns are common entry points for SQL injection attacks. 2️⃣ Identifying data overexposure It can point out views or queries that return sensitive columns (such as personal data or credentials) without masking or filtering them appropriately. 3️⃣ Recommending stronger protections It suggests improvements such as encrypting connections, using Always Encrypted, applying Dynamic Data Masking, or preferring Entra ID authentication instead of storing credentials in code or configuration. 4️⃣ Illustrating how an attack might work In some cases, it can generate realistic SQL injection payload examples based on your schema. This helps you understand the practical impact of a vulnerability, not just the theory. How to try it You will need: • VS Code with the MSSQL extension (v1.37+) • Your GitHub Copilot subscription • A connection to a SQL Server or Azure SQL database (a dev database is recommended) Sample DB: https://github.com/Microsoft/sql-server-samples/releases/tag/wide-world-importers-v1.0 As a starting point, connect to a sample or development database (for example, AdventureWorks). Then open the Copilot chat and try prompts such as: "@mssql Review the stored procedure SalesLT.uspGetCustomerOrderHistory for potential SQL injection vulnerabilities" "@mssql What security best practices should I verify for the SalesLT schema?" The tool will analyze the referenced objects and return recommendations based on the real structure of your database. It is possible that the AI‑generated content is incorrect. You remain responsible for reviewing, validating, and approving it before any use. Do not rely on this output without thorough human verification. Not intended for production use. Important limitations The Security Analyzer is helpful, but it has boundaries you should be aware of: Conversational, not a batch scanner: There is no built-in "scan everything" button. To review many procedures, you need to guide it or script interactions. Depends on context: If it is not connected to your database, it falls back to more generic suggestions that may be less useful. Can be wrong: Like all large language models, it can occasionally refer to objects that do not exist or misinterpret a situation when the context is incomplete. Always review its advice before making changes. Not a formal security audit: It is designed to help in day-to-day development and maintenance, not to serve as a compliance or certification tool.

Resource governor - a new beginning
Executive summary In addition to increased CPU and memory limits, we are making another change to benefit customers using the SQL Server Standard edition. Starting with SQL Server 2025, resource governor, previously an Enterprise edition feature, is also available in the Standard edition. A powerful tool Resource governor has been a part of SQL Server for more than 15 years. It’s a powerful, full-featured tool that improves reliability when multiple applications or users share resources on the same SQL Server instance. We rely on Resource Governor to isolate workloads on our SQL Server instances by controlling CPU and memory usage. It helps us ensure that the core of our trading systems remains stable and runs with predictable performance, even when other parts of the systems share the same servers. - Ola Hallengren, Chief Data Platforms Engineer at Saxo Bank and a Data Platform MVP Yet when we ask customers if they use resource governor, a frequent answer is "We can't. We are on Standard edition." Indeed, ever since its initial release, resource governor has been an Enterprise-only feature. That made it less known and less commonly used than it deserves. We heard and acted on your feedback. Starting with SQL Server 2025, resource governor is available in both Standard and Enterprise editions, with identical capabilities. This includes the respective Developer editions as well. In Azure SQL Managed Instance, resource governor is already available in all service tiers. What can it do? Here are just some of the things you can accomplish using resource governor: Limit or reserve CPU bandwidth and IOPS for a workload. Limit the size of query memory grants or reserve memory for query processing. Limit the total number of running requests (queries) for a workload. Abort query batches that exceed a specified amount of CPU time. Set a hard cap on the maximum degree of parallelism (MAXDOP) for queries. (New in SQL Server 2025) Limit the amount of tempdb space a workload can use (blog | doc). Whether you are on Standard or Enterprise edition, if you haven't used resource governor yet, see what it can do for you. To help you learn, we have a new step-by-step guide with best practices and examples, from simple to more advanced. There is also a separate guide focusing on the new tempdb space governance feature. Conclusion With this change, customers on Standard edition get a powerful enterprise-grade tool to control resource contention and improve reliability of their SQL Server environments. We encourage you to learn more about resource governor to understand the full range of its capabilities. Have questions or feedback? Post a comment on this blog post, an idea at https://aka.ms/sqlfeedback, or email us at sql-rg-feedback@microsoft.com. Let’s make resource governor a standard (😊) tool in your toolset!SQL Server 2025 is Now Generally Available

At Ivanti, our mission is to elevate human potential by managing, protecting, and automating technology to drive continuous innovation. SQL Server 2025 plays a crucial role in helping us achieve this goal. By harnessing the advanced capabilities of SQL Server 2025 and Azure OpenAI, we are building intelligent, agentic tools that empower customers to access knowledge and resolve incidents faster. Sirjad Parakkat, Vice President, AI Engineering | Ivanti Made for developers This release is the most significant for SQL developers in a decade, streamlining development and boosting productivity. Native JSON support, REST APIs,RegEx and Fuzzy string match enable richer data enrichment and validation. Change event streaming allows real-time, event-driven applications by streaming changes directly from transaction to Azure Event Hubs, reducing resource overhead compared to CDC. SQL Tooling SQL Server 2025 delivers major updates across the data platform. SQL Server Management Studio (SSMS 22) is now generally available, offering official support for SQL Server 2025, enhanced AI assistance, and ARM64 support. SSMS 22 also includes AI assistance when you install the GitHub Copilot workload, which leverages the same GitHub subscription you use with GitHub Copilot in Visual Studio or VS Code. The Microsoft Python Driver for SQL Server (mssql-python) is generally available, providing a modern, high-performance connector with Entra ID authentication. "SQL Server 2025 offers two major functionalities which are very important to us and will bring SQL Server into the future – native API calls and RAG. In the past we’ve had to use custom assemblies for making API calls, which can be a huge problem when you have to make hundreds of thousands of API calls and the remote systems are slow to respond, creating large queues and high CPU load in SQL. With RAG and vector search, we can now implement countless AI possibilities, making data searchable in ways previously impossible.” Alex Ivanov, CTO, eDynamix Best-in-class security, performance, and availability SQL Server 2025 builds on its foundation as the most secure database in the last decade, introducing modern identity and encryption practices, including Microsoft Entra managed identities for improved credential management. Optimized locking reduces lock memory consumption, minimizes blocking, and boosts concurrency. Tempdb space resource governance improves server reliability. Optional parameter plan optimization makes query performance more stable. SQL Server 2025 continues to strengthen its mission-critical capabilities with enhancements to Always On availability groups (AGs) and disaster recovery options. The focus is on faster failover, improved diagnostics, and hybrid flexibility. Preliminary benchmarks show SQL Server 2025 running on AMD EPYC processors with HPE hardware delivers measurable gains in performance and value. For performance, the 10TB workload sets a new record for SQL Server. In price-performance, SQL Server 2025 achieves a 4% improvement in the 3TB category compared to previous results. “At Infios, we are very excited about several new features in SQL Server 2025 and the vast amount of opportunities for performance improvements. We are most excited about the optimized locking feature and how that can drastically help reduce locking across our customers and all their unique workloads. Optional Parameter Plan Optimization (OPPO) could also be huge for us with SQL Server being able to reduce parameter sniffing issues. Persisted statistics on secondary replicas will also be beneficial for the rare occurrence that we have a failover event. While we’ve been pleased with all the improvements to tempdb in previous versions, resource governance to prevent runaway queries and consuming large amounts of disk space in SQL 2025 is a big improvement for us. ” Tim Radney, SaaS Operations Manager, Infios Cloud agility through Azure and Fabric SQL Server 2025 enhances cloud agility with support for database mirroring in Fabric, enabling near real-time analytics with zero-ETL and offloading analytical workloads. Azure Arc integration continues to provide unified management, security, and governance for SQL estates across on-premises and cloud environments, empowering organizations to scale and modernize with confidence. “With Fabric Mirroring in SQL Server 2025, ExponentHR can effortlessly mirror numerous datasets to fabric, enabling near real-time analytics. This technology has alleviated the need for expensive and complex ETL operations and enables more productivity for our customers. Thanks to SQL Server 2025’s built-in cloud connectivity, we can directly process large amounts of data efficiently and overcome traditional bottlenecks.” -- Brent Carlson, IT Manager, ExponentHR SQL Server 2025 on Linux SQL Server 2025 on Linux introduces several important enhancements. Security is strengthened with TLS 1.3 support, custom password policies, and signed container images. Platform support expands to include RHEL 10 and Ubuntu 24.04, while performance is improved through tmpfs support for tempdb and container-based deployments. Advanced analytics are enabled with generic ODBC data source support via PolyBase. Developer experience is streamlined with Visual Studio Code integration for local container deployment using the mssql extension and validated deployment patterns in partnership with Red Hat, supporting modern workloads and AI scenarios across hybrid environments. "The work we’re doing with Microsoft to optimize SQL Server on Red Hat Enterprise Linux is a powerful testament to the strength of our collaboration. With the new features in SQL Server, including support for Red Hat Enterprise Linux 10 and enabling streamlined deployment via Red Hat Ansible Automation Platform, we are making it easier than ever for customers to deploy and manage this critical workload across the hybrid cloud. This collaboration extends beyond just enabling core performance to deliver innovative, validated patterns, such as leveraging Red Hat Enterprise Linux AI with SQL Server for retrieval-augmented generation (RAG) and generative AI scenarios, and providing a more consistent experience for customers, whether they are deploying via the Azure Marketplace or on-premises.

Preview Features & Flexibility In SQL Server 2025, customers can explore new database features using an opt-in mechanism through database-scoped configurations. Certain features, such as vector indexes, are introduced this way, allowing customers to try them in preview even while SQL Server is generally available. These features will become fully available in a future SQL Server 2025 update, at which point the database-scoped configuration will no longer be required. Our goal is to make preview features generally available within approximately 12 months, guided by customer feedback and our commitment to delivering high-quality experiences. Learn more.
