There are some questions about ***[immutable servers][1]***, such as:

- https://devops.stackexchange.com/q/207/40
- https://devops.stackexchange.com/q/109/40

It seems obvious that it has to do with servers (that part I get). And just digesting the grammar of ***immutable***, I would think it has something to do with "not possible to *mute*". If that guess is close, I'd have no clue what exactly cannot be muted (and I doubt it has to do with soundcards or something ...).

**My questions**:

- What is actually a "immutable servers" (in the context of DevOps)?
- Why are they used?
