What is DevOps?
DevOps is a culture where Developers and Operations staff of the application/service exchanging their ideas throughout the development lifecycle.
If you want the definition of DevOps it won’t be like this. The statement that I have given at top is just to clear the way you are watching and thinking about DevOps.
In-depth Definition of DevOps:
DevOps is a new term emerging from the collision of two major related trends. The first was also called “agile infrastructure” or “agile operations”; it sprang from applying Agile and Lean approaches to operations work. The second is a much-expanded understanding of the value of collaboration between development and operations staff throughout all stages of the development lifecycle when creating and operating a service, and how important operations has become in our increasingly service-oriented world
First of all, DevOps is not a title/job/profession, DevOps is a culture.
A healthy culture of organization’s Dev and Ops guys to cooperate with each other.
DevOps is talking about many aspects of Development and Operations processes while trying to optimize the engineering organization for growth and infrastructure for scale.
DevOps culture is talking about:
- Engineers empowerment – by giving engineers more responsibility for the whole application lifecycle process. (dev -> test -> deploy -> monitor -> be on call)
- Test Driven Development – write tests before you write code. Unit tests, integration tests, system tests. This will help increase the quality of your service and give you more confidence to release faster and more frequent.
- Automation – automate everything that can be automated. Test automation, infrastructure automation (infrastructure as a code), deployment automation, etc..
- Monitoring – monitor your apps, build monitoring alerts well. It should save your time, don’t flood with metrics and alerts.
- Self-service – provide a self-service for any framework that you build or anything that you do. Don’t be a bottleneck.
People – but most importantly it’s talking about people culture that should be open-minded, transparent, egoless, professional, with “can do” attitude.
