Development, Test and Production environments

different-environments

When you are developing something with a little more complexity than a hello world software (which should be all the time) it is REALLY important to have at least three different environments: Development, Test / Staging ¬†and Production. This is even more important in web development as it is “fairly” easy to do in small / medium projects.

 

The Development environment is where developers live and breathe, where they make all the changes, mistakes and fixes that you need. It’s like a small lab where nobody judges you, where it does not matter if you break the CSS or your whole webpage as nobody is going to notice. Once you achieve something, like developing a new item of a list, fix a bug, or a new functionality, you should stop and move your functionality to the Testing environment.

 

The Testing / Staging environment is a little different. Actually, there is a slight difference between testing and staging environments, but to distinguish them is not the point here. You need something that acts as a copy of your corporate site, a copy of the live version. It should be EXACTLY the same, because you are going to test in this environment your new developments, you want to know how it will work and IF it will work live before going live. Only once you have verified that everything works, that your new functionality has not broken anything, you can migrate the changes to the production environment.… Read the rest of “Development, Test and Production environments”
