Central to the idea of DevOps is collaboration between all of the teams involved in IT applications and infrastructure. Developers, Operations, Quality Assurance, Security, and more, all have stakes in the delivery of a product or service. So, what does collaboration mean when it comes to monitoring in the world of DevOps? In the past, different teams involved in creating or maintaining an application would first finish their portion completely before passing it on to the next team. For example, the Development team would first write code for the entire app, or specific features in the app, before passing it to the Quality Assurance (QA) team. The QA team would then do their testing and analysis before sending it forward to Operations, and so on.
