I like that they have an easy way of getting all your cloud services into one dashboard - its quite comprehensive! It would be great if you could customise it more so each service has their own section with everything relating to them such as networking etc., rather than having 1 big list.
Also when using VMs we find ourselves looking at the VM size which is not ideal because sometimes we want extra space but cant see this option from within opscompas (maybe thats just us). Using OPCompass to help manage our various IT infrastructure including VMware vSphere & Hyperconverged infrastructures across public clouds Amazon Web Services & Microsoft Azure environments, and also physical servers running Linux/Windows OSes. We use their reporting features to produce consolidated monthly reports showing usage metrics against planned quotas across both private and hybrid cloud.
