Review on OpenNebula by Paul Monzon

I like that it is open source - which means you can modify any part of their code to suit your needs without paying them money! They do have some very expensive features but if they are required then this should be discussed with support before purchasing because there may well not even exist another solution out-there at all affordable enough (even by comparison) in terms of cost per month/year etc..

Their customer service department has been absolutely brilliant throughout our relationship so far too!! It's hard work having such an active user base as we need constant updates from different parts within OPNBULA itself or else certain things break down quickly when using multiple cloud environments across various providers simultaneously i.e VMWare vs HyperV / KVM & XenServer compared against each other + AWS EC2 instances running containers ecosystmically alongside Azure VMSSs where possible.
