Many DevOps engineers fail to test their automation code in the same way they test the software they deploy. It's crucial for software to have tests, and this should apply to infrastructure-as-code software too, if we plan to change and improve this code with no worries about breaking automation in our DevOps pipeline.

The first step in any significant software procurement is to assure there is a clear definition of the business problem being solved. If you don’t know what you want, you aren’t prepared to negotiate for it, so you'll end up with a system or tool that isn't what you need—and you'll likely be disappointed at delivery.

In the world of continuous integration and continuous delivery, the importance of ensuring good performance has increased immensely.
