Redis is a key-value storage. Redis is an in-memory database — all data resides in RAM and is periodically replicated to disk.
Redis is suitable for tasks where you need to process data quickly and do not necessarily need to store it on disk. For example, for storing user sessions — whether the user is currently authorized or not. The service must receive such data instantly, and it is faster to read it from RAM.
