This is the second article exploring the capabilities of Redis. https://thenewstack.io/redis-data-types-the-basics/ shared the basic data types and models to get started with Redis.

Individual consumers, via the application, connect to the Redis database instance that is nearest to their geographic location. The Active-Active Redis database instances are then synchronized in a multimaster model so that each Redis instance always has a complete and up-to-date copy of the data.
