Review on OpenNebula by Bim Cook

I like that it is open source software allowing anyone to use without any restrictions. It's pretty easy once you get your hands dirty with Linux commands which helps getting started fast! You'll need linux skills in order to run this as-is especially when configuring templates or creating new images. If there are no windows VMs available then using vmware player could be an alternative since it has limited hardware requirements (2GB RAM). Using cloud instances instead of dedicated servers can save money over time but requires some knowledge about how different types work together in terms of networking configurations etc., otherwise you may end up wasting resources due to misconfigurations. We have been able to deploy virtual machines at a lower budget compared to buying commercial products offered by other vendors.
