I want to use Redis as a cache storage for multiple applications on the same physical machine.

I know at least two ways of doing it:

  1. by running several Redis instances on different ports;
  2. by using different Redis databases for different applications.

But I don't know which one is better for me.

What are advantages and disadvantages of these methods?

Is there any better way of doing it?

Generally, you should prefer the 1st approach, i.e. dedicated Redis servers. Shared databases are managed by the same Redis process and can therefore block each other. Additionally, shared databases share the same configuration (although in your case this may not be an issue since all databases are intended for caching). Lastly, shared databases are not supported by Redis Cluster.
