ElastiCache is Amazon's managed Redis service that has seen wide adoption over the past decade, particularly among businesses moving to the cloud who sought speed, scalability, and resilience in their digital experiences. However, as businesses scale, they often outgrow ElastiCache's limitations, such as its inability to provide enterprise-grade functionality required by larger organizations. This can be identified by signs of high read volume, write-heavy applications, and need for multi-cloud or on-premises replication. To address these limitations, Redis Enterprise offers advanced features like Active-Active Geo Distribution, which provides industry-leading SLA for 99.999% availability and supports local latency regardless of geo-replicated regions. Additionally, Redis Enterprise offers data tiering with Redis on Flash, which maintains application performance while moving less-frequently accessed data to SSD, providing faster replication times and safeguarding customer data with built-in persistence. Furthermore, Redis Enterprise Cloud offers multi-tenancy, where a single subscription serves hundreds of tenants, each with its own isolated Redis database endpoint, providing scope economies for service providers.
