Azure offers two Redis services, Azure Cache for Redis and Azure Managed Redis, which initially might seem redundant but serve distinct purposes. Azure Cache for Redis, the original service, featured various plans with different cores, leading to challenges in code and data migration when upgrading, as well as high costs for certain tiers. In contrast, Azure Managed Redis was developed to provide a more seamless experience by using Redis Enterprise software across all tiers, offering flexibility with performance-based tiers rather than feature-gated ones. This new service allows developers to easily scale or switch tiers without migration, making it more cost-effective and suitable for production. Tuned specifically for Azure infrastructure, Azure Managed Redis offers enhanced performance and has become integral for AI applications, supporting advanced functionalities like vector search and semantic caching. For new projects in Azure, Azure Managed Redis offers a consistent and scalable solution that adapts to growing workloads.
