Why Choose ScaleOut Over Redis®*

Can’t risk serving stale data?

Tired of configuration hassles?


ScaleOut StateServer® offers a better combination of features, always serves the latest data, is easy to manage, and has been battle-tested for more than a decade — with world-class support for the enterprise.

And … it now supports Redis clients as an execution platform!

When you are deploying a distributed cache to host your company’s mission-critical data, you need a product on which you can depend.

Unlike Redis, ScaleOut StateServer was designed from the ground up to host your mission-critical data with fast, scalable access and integrated high availability. Starting with version 5.11, it also serves as an execution platform for Redis clients and runs open-source Redis code for all five core data structures. Learn more.

When compared to Redis, here’s what sets ScaleOut StateServer apart:

  • Integrated distributed caching architecture — no need for a separate third-party add-on pack to handle sharding, scaling, and high availability
  • The industry’s leading ease of use with full GUI management, automatic configuration and dynamic load-balancing
  • Fully coherent data storage and access using patented quorum-based data replication so that cache updates are never lost
  • Integrated, shard-aware client support in Java, C#, and C++ with built-in, client-side caching.
  • WAN-based data replication (using optional ScaleOut GeoServer®) that automatically scales with your caching cluster
  • Advanced features for data analytics, including fully distributed MapReduce, and cluster-aware, server-side scripting in Java and C# with automatic code shipping

What sets ScaleOut apart from Redis?

The answer is simple — architecture. Redis originally was designed to replace a SQL database with a single server, in-memory, data structure store to cache data generated by a local website. Its single process, single threaded design focused on combining data structure operations with an in-memory cache. However, the key features required by a distributed cache had to be bolted on later by third parties.

In contrast, ScaleOut StateServer was conceived as a scalable, distributed, in-memory data store with integrated data consistency, sharding, scaling, and high availability. This led to a robust, highly reliable architecture that incorporates the latest industry-leading technology and minimizes management costs.
