What is the advantage of using Redis for session storage over simply storing all data in variables inside your app?

So that sessions can survive crash of your app. And be accessible from multiple app instances. – Sergio Tulentsev Dec 27 '12 at 12:35

From the top of my head:

Pros of storing sessions in external storage (redis) vs in-process

sessions survive crash of app server
sessions are shared between all app servers (if you have more than one).

Cons:

slower than storing in-process (because of network latency)
requires setting up and managing the storage
