The same process can hold a cache, a queue, a lock, and a session. Those are different contracts.
I used to say “Redis” the way people say “the cache”. In Laravel apps it is often also:
A maxmemory-policy that is acceptable for cached HTML is not acceptable for a lock. Evicting a cache key is a performance issue. Evicting a lock is a correctness issue.
Longer version: How I think about Redis in Laravel.
