The software development life-cycle has a lot of moving parts. A huge problem many large companies have is maintaining a consistent deployment process. Written steps sometimes get skipped; manual deploys are error prone, and home-grown deploy scripts are usually only understood by the person that wrote them. Companies like Netflix, Etsy, and Amazon need to make sure that deployment cycles are smooth and errors are caught as early in the process as possible.

When you have problems consistently getting to production where the customers are, your company will start to lose the trust and confidence of the users. That’s where DevOps comes in.

What is DevOps?

DevOps is a shift in the way a company handles its deployment process. In many organizations, the code is handled by developers and the deployment is handled by the operations team. The fundamental problem that DevOps solves is the slow turn-around time for bug fixes and new feature releases.

The Waterfall cycle is still commonly used and its biggest drawback is how long it takes to get from development to deployment. In the DevOps culture, developers have some control over the way apps get deployed to production. This makes it easier to get changes out faster, more consistently, and with less errors that effect the user’s experience.

In DevOps, you’ll notice that the flow is similar to the Waterfall cycle but it’s more streamlined and automated.

The DevOps Cycle

There are different parts of the DevOps life-cycle: Version Control, Continuous Integration, Continuous Delivery, and Continuous Deployment. Version control is something that developers work with all of the time in the form of Git and other tools like GitHub or BitBucket.
