title: How does in-memory cache acts as distributed?
body: <p>I know that REDIS cache is an example of in-memory cache. But it (REDIS) can also acts as distributed cache.</p>
  <p>My question is where exactly is cached data stored in in-memory cache. Is the cache deployed directly on the application server? If yes, then how does REDIS being an in-memory cache acts as distributed?</p>
