DEVOPS WEEKLY ISSUE #211 - 18th January 2015
The topic of whether devops needs a manifesto arose again this week. In my view devops has always just been a word under which lots of conversations can happen. It’s pure and simple marketing (in a good way), where the product is the conversation and the community.
