Unless you have been living under a rock for the last few years you are probably well aware that Cloud hosted servers or (infrastructure as a service as it is called) is currently all the rage. It does have some great advantages, like not having to maintain any hardware and the ability to increase/decrease resources at the push of a button to name two of the big ones. However, it can be bloody expensive if you don’t manage it correctly.
One way to help lower the cost is to turn off non essential cloud based virtual machines when you aren’t using them. In my case I use my personal Azure subscription as a dev/test environment so I only need the machines powered on when I want to use them.
