Advantages of Redis Enterprise

Redis Enterprise is the best way to deploy Redis databases inside your VPCs, fundamentally because it is optimized for delivering the most stable performance and availability, least operational overhead and the most value from your infrastructure.  With its unique architecture that includes a cut-through proxy, shared nothing cluster architecture and built-in multi-tenancy, you can run many more Redis databases on the same hardware and gain the most out of your spend. The unique Redis on Flash technology allows for even greater cost-savings, particularly for large datasets with low latency requirements.

With Redis Enterprise, you can not just run multiple Redis databases on the same server instances, but also, reduce the number of copies of data you need to keep to resolve quorum issues during network splits.  With its unique WAN compression technology and diskless WAN replication coupled with single digit failover times, Redis Enterprise assures true protection against regional and entire cloud failures.

The versatility of Redis Enteprise enabled by various modules, including built-in search, ReJSON and many more, allows you to meet a variety of data processing needs with the same datastores. Alternatives offered by cloud vendors are many versions behind and are extremely inefficient in their usage of hardware as they simply run single threaded Redis even on the largest instances and provide inadequate, brittle scaling and insufficient high availability or durability options.
