Continuous Delivery and Devops A Quickstart Guide, second edition, Paul Swartout, (Book – 2014 )
Programmers: do you have difficulty getting your new code onto the site? Administrators: do you have difficulty keeping the site stable with all the changes coming at you? Give this excellent book to your manager, and make sure he at least sees the cool cartoons showing Devs, Ops, and Managers interacting. Then talk to the marketing folks, and learn how to promote Continuous Delivery (or DevOps, choose what lingo you want). Learn how to say ‘talk the talk, walk the walk’ convincingly. Keep at it until Devs and Ops can work together to make changes daily, with 99.999% up-time.
And have a look at Paul’s additional resources.
