WHERE DID DEVOPS COME FROM?
ESM (Enterprise Systems Management) Administrators brought the key ESM practices to DevOps like configuration management, automated provisioning, system monitoring, and the toolchain approach, etc.
Agile Development DevOps can be considered as an outgrowth of the Agile. It is simply extending the Agile principles beyond boundaries of the code to the entire delivered services.
