Azure Managed Redis is a Microsoft first-party, fully managed in-memory data store, replacing Azure Cache for Redis tiers. It includes Redis Enterprise features such as RediSearch for vector search and full-text search, in addition to RedisJSON, RedisTimeSeries, and Active Geo-Replication. As Azure Cache for Redis reaches end of life, more teams are planning migrations to Azure Managed Redis in search of better performance, lower cost, and modern capabilities for AI and real-time workloads.

Cache migrations are deceptively risky. Redis often handles latency-sensitive user requests, so an undersized cache, a misconfigured client, or a forgotten dependent service can result in immediate user-visible slowness or outages. Two things make the difference between a clean migration and an unsuccessful one: a single observability layer covering both sides of the cutover, and a reliable way to move data and traffic. Together, Datadog and Eden meet both requirements.

Datadog provides unified observability across the legacy cache and the new Managed Redis deployment, helping teams capture premigration performance, monitor the cutover, and validate performance after migration. Eden provides the app-aware execution layer for data replication, traffic routing, dual-write consistency, and instant rollback.
