Redis is good for simple data caching use cases, but in the real world, you will want more than simple caching from your in-memory computing platform. When you’ve hit a wall at scaling Redis or struggled to work around its security issues, it’s time to turn to Hazelcast. The Hazelcast In-Memory Computing Platform joins Hazelcast IMDG and Hazelcast Jet to enable not only a high-performance cache, but also stream and batch processing at microsecond speeds.
There are a list of reasons to switch from Redis to Hazelcast. Repeatable benchmarks show that Hazelcast is many times faster. Redis is single-threaded, so it does not efficiently scale for larger loads, while Hazelcast performance scales linearly with additional resources. Hazelcast is easy to use, and it can be embedded in apps or deployed in a client-server model. Hazelcast is extremely secure, and the security overhead only has a negligible effect on performance.
