After a quick review of "Continuous integration tools and best practices", I also did read more about "Continuous Delivery (CD)", and I found some great articles about it that worth to read by every sysadmin, developer, and DevOps.
- The Continuous Delivery Maturity Model (full post).
- Continuous Delivery Maturity Model (IBM).
- Continuous Integration, Delivery, Deployment and Maturity Model.
- Continuous Delivery Maturity Model (Praqma PDF).
One more bonus post I really loved it: Get DevOpstastic! Optimized DevOps! (it's not really about continuous delivery, but DevOps in general).
And remember, "If it's not broke, fix it! By making it better!"! Always review and re-evaluate how you are doing things! Have a nice day :-)
