Immutable Infrastructure: 6 questions to 6 experts

​Immutable Infrastructure is not a new concept and while there are many examples of successful implementations it would be a lie if we said that the recent hype around containers in general and Docker in particular hasn’t made the concept more widespread.

As it often happens in these cases, we see a lot of different interpretations of its meaning, benefits, challenges, and adoption paths. We asked 6 experts who have been thinking, writing and implementing Immutable Infrastructures to share their experience by answering 6 questions on the topic:

1) What does Immutable Infrastructure mean to you?
2) What’s your position on Immutable Infrastructure and why?
3) What are the main benefits you see/care about?
4) Biggest adoption challenges/things that are not there yet in your opinion?
5+6) Starting from scratch is (relatively) easy. What about those with existing systems? any hints on how others could get started moving towards an Immutable Infrastructure?
