I like that it's easy to setup, manage, scale with minimal effort. It can be customized by any user/admin without much difficulty (in fact you don't need any coding skills). The UI could use some improvement but nothing major. Make sure you have good internet connectivity otherwise this software will not work well in most cases. We are solving our infrastructure problems of having different servers or VMs running all day long as we needed more capacity during peak hours. This was solved using canonical maas which allows us to create multiple nodes at once from one master node easily.
