Azure Cache for Redis Retirement: What to Know and How to Prepare
Microsoft has announced the retirement of Azure Cache for Redis (Basic, Standard, Premium) and Azure Cache for Redis Enterprise/Enterprise Flash tiers. If you rely on these services today, it’s important to understand what’s changing, when, and how to prepare for a smooth transition to Azure Managed Redis. What’s Retiring and When? Azure Cache for Redis (Basic, Standard, Premium): Creation blocked for new customers: April 1, 2026 Creation blocked for existing customers: October 1, 2026 Retirement Date: September 30, 2028 Instances will be disabled starting October 1, 2028 Azure Cache for Redis Enterprise/Enterprise Flash: Creation blocked for all customers: April 1, 2026 Retirement Date: March 31, 2027 Instances will be migrated to Azure Managed Redis starting April 1, 2027 Existing instances will continue to run and receive regular maintenance until their respective retirement dates. More information here. Why Move to Azure Managed Redis? Azure Managed Redis is built on Redis Enterprise software, offering significant improvements: Enterprise-grade features: Active geo-replication, Redis modules, and more Performance & Cost: More performant and cost-effective than all tiers of Azure Cache for Redis Reliability: Zone redundancy by default, up to 99.999% availability with geo-replication Simplified Management: Native Azure experience, no Marketplace component, easier provisioning and billing compared to Azure Cache for Redis Enterprise Migration Guidance: What Customers Need to Do Upgrade Early Microsoft recommends upgrading to Azure Managed Redis as soon as possible, rather than waiting for the retirement deadline. Early migration ensures you benefit from new features and avoid last-minute disruptions. Migration Tooling For Basic/Standard/Premium: A command-line migration experience will be available in phases from February 2026, starting with the Basic caches support in preview. This tooling will allow you to migrate your cache endpoint, using the same hostname and access key for a seamless transition. For Enterprise/EnterpriseFlash: Migration tooling will roll out in phases starting March 2026. Downtime: If you use the migration tooling, expect only a brief connection blip (a few seconds) when the DNS record is updated. This is similar to the downtime experienced during regular maintenance. Application Changes Update your Redis hostname and access key to point to the new Azure Managed Redis instance. Azure Managed Redis is clustered by default. Most client libraries (e.g., StackExchange.Redis) work out-of-the-box, but check your library’s documentation for cluster support. Non-clustered support is available up to 25GB, but clustering is recommended for performance and scalability. For migrating data, see various options outlined in this blogpost: Data Migration with RIOT-X for Azure Managed Redis | Microsoft Community Hub and here. Reservations You can cancel or exchange your existing reservations for Azure Cache for Redis as described in Microsoft Cost Management documentation. Feature Parity and Regional Availability: What’s Coming and When Azure Managed Redis is actively being enhanced to close feature gaps and expand regional coverage. Here are the key ETAs for upcoming features and regions (all dates are tentative): Azure Public Regions France Central: November 2025 Qatar Central: December 2026 Azure Sovereign Clouds China Cloud: February 2026 US Gov Cloud: February 2026 Larger SKUs Memory Optimized, Balanced, Compute Optimized (up to 500GB): March 2026 Flash Optimized (up to 1000GB): March 2026 Management Operations Scheduling maintenance windows: February 2026 Keyspace notifications: March 2026 If you need a feature or region that isn’t yet available, reach out to support or email AzureManagedRedis@microsoft.com for guidance. Resources for a Smooth Migration Migration Overview & Guidance Choosing the Right Tier Azure Managed Redis architecture Key Takeaways for Customers Don’t wait—start planning your migration to Azure Managed Redis now. Migration tooling will make the process easier, with phased rollouts starting November 2025. Feature parity is a priority, with major gaps closing by March–June 2026.

We’re excited to announce the General Availability of On-Demand Backups in Azure Database for PostgreSQL – Flexible Server! In today’s dynamic data management landscape, ensuring the protection and recoverability of your databases is essential. Azure Database for PostgreSQL – Flexible Server streamlines this responsibility through comprehensive backup management, including automated, scheduled storage volume snapshots encompassing the entire database instance and all associated transaction logs. With the introduction of On-demand backups you now have the flexibility to initiate backups at any time, supplementing the existing scheduled backups. This capability is particularly valuable in scenarios involving high-risk operations, such as system upgrades or schema modifications, or when performing periodic data refreshes that do not align with the standard backup schedule. Benefits Instant Backup Creation: Trigger a full backup of your server on demand—no more waiting for the automated backup schedule. Cost Optimization: While Azure manages automated backups that cannot be deleted until the retention window is met, on-demand backups provide greater control over storage costs. Delete these backups once their purpose is served to avoid unnecessary storage expense. Enhanced Control & Safety: Take backups before schema changes, major deployments, or periodic refresh activities to meet your business requirements. Seamless Integration: Accessible via Azure Portal, Azure CLI, ARM templates, and REST APIs. Azure Database for PostgreSQL Flexible Server provides a comprehensive, user-friendly backup solution, giving you the confidence to manage your data effectively and securely. Let us explore how on-demand backups can elevate your database management strategy and provide peace of mind during high-stakes operations. Automated Backups vs On-Demand Backups Feature Automated Backups On-Demand Backups Creation Scheduled by Azure Manually initiated by the user Retention Based on the backup policy Based on the backup policy Deletion Managed by Azure User-controlled Use Cases Regular data protection High-risk operations, ad-hoc needs How to take On-Demand Backups using the portal. In the Azure portal, choose your Azure Database for PostgreSQL flexible server. Click Settings from the left panel and choose Backup and Restore. Click Backup and provide your backup name. Click Backup. A notification is shown that an On-demand backup trigger has been initiated. For more information: How to perform On-demand backups using Portal How to take On-Demand Backups using CLI. You can run the following command to perform an on-demand backup of a server. az postgres flexible-server backup create --resource-group <resource_group> --name <server> --backup-name <backup> Example: For more information: How to perform On-demand backups using CLI How to list all on-demand backups using CLI You can list currently available on-demand backups of a server via the az postgres flexible-server backup list command. az postgres flexible-server backup list --resource-group <resource_group> --name <server> --query "[?backupType=='Customer On-Demand']" --output table For more information: How to list all backups using Portal What's Next Once you have taken an on-demand backup based on your business needs, you can retain it until your high-risk operation is complete or use it to refresh your reporting or non-production environments. You can delete the backups to optimize storage costs when the backup is no longer needed. To restore or delete on-demand backups, you can use the Azure portal, CLI, or API for seamless management. Limitations & Considerations: SKU Support: On-demand backups are available for General Purpose and Memory-Optimized SKUs. Burstable SKUs are not supported. Storage Tier Compatibility: Currently, only the SSDv1 storage tier is supported. Support for SSDv2 is on our roadmap and will be introduced in a future update. You can take up to 7 on-demand backups per flexible server. This limit is intentional to help manage backup costs, as on-demand backups are meant for occasional use. The managed service already provides support for up to 35 backups in total, excluding on-demand backups. Take Control of Your Database Protection Today! The ability to create on-demand backups is critical for managing and safeguarding your data. Whether you're preparing for high-risk operations or refreshing non-production environments, this feature puts flexibility and control in your hands.
