Replication and High Availability
- Redis supports replication, which allows you to create multiple copies of your data across different servers. This provides fault tolerance and high availability, as clients can connect to any of the replicas if one of the servers fails.
- Redis also supports clustering for horizontal scaling, allowing you to distribute your data across multiple nodes.

It can be used as a database, cache, and message broker, and supports various data structures such as strings, lists, sets, and hashes. Redis is often used in applications requiring high-performance, low-latency access to data, such as real-time analytics, caching, and messaging queues. Its simplicity, speed, and rich feature set have made it a popular choice among developers.
