I have been having a great debate with one of my colleagues about the changing role of the IT operations (aka “I&O”) function in the context of PaaS. Nobody debates that I&O is responsible and accountable for infrastructure operations.
Application developers (with or without the blessing of Enterprise Architecture) select platform components such as application servers, middleware etc. I&O keeps the servers running – probably up to the operating system. The app owners then manage their apps and the platform components. I&O has no SLAs on the platform, etc.
In the PaaS era, I think this needs to change. IT Operations (I&O) needs to have full accountability and responsibility for the OPERATION of the PaaS layer. PaaS is no longer a part of the application, but is now really part of the core platform operated by IT. It’s about 24×7 monitoring, support, etc. and generally this is a task that I&O is ultimately best able to handle.
