What is DevOps?

DevOps is the application of the Development life cycle to your Infrastructure Operations, Datacentre and Cloud computing environments beneath.

Yes, the Developers are coming over the hill and are taking the SysOps jobs! Everything will be managed a single grand unified way. Sysadmins look out! They’ll automate you out of existence with self-serve apps!

Now that servers run in VMWare and in Containers of isolated UNIX and Linux software stacks sharing a common underlying kernel, servers that were once hardware, are more often-than-not, now software entities or “microservices”.

As such, development processes can be applied to the management of their lifecycle, coining the term “Infrastructure As Code” and not just to the upper Application Layer in the OSI Model.

Processes

DevOps means doing better and proper processes. The first thing to know is what processes exist and then to check if and how you implement them in your organisation/IT department.
