What is DevOps?

DevOps is a made-up word for Software Development (Dev) and Information Technology Operations (Ops). It is often viewed as:

A set of practices, tools and a cultural philosophy that automate and integrate the processes between software development and IT teams.

So…?

DevOps is the practice of automating the tedious IT processes that have to be performed on a regular basis to ease tasks for tech teams. DevOps is most useful in Agile environments where change is constant and regular.

Recall:

Agile is a software development methodology that is based around regular, equal-sized sprints in which the team develops, tests and deploys changes to the software.

Consider project X,

• The team has daily standups.
• The team works on the current required changes.
• Testing is done soon after development.
• Every 2 weeks:
  • Stakeholders reflect on past changes and provide feedback.
  • Plans are made for the upcoming 2-week sprint.
• Deployment is done every 4 weeks to make essential changes live. </aside>
