Middlewares qualitative comparison 2011

Middlewares Qualitative Comparison (versions of 2011)

This table comparison is a bit extraction of my master’s thesis submitted last year. However, now this information may be outdated because OpenNebula and OpenStack are evolving so fast.

New middlewares and big communities are emerging. Now OpenStack is taking strong. When we began my researches, OpenStack did not exist and during the development of my researches OpenStack is starting to emerge. OpenStack promises a lot and it is an important rival for OpenNebula. But now we think that OpenNebula has a better position to be a standard and it is the best open-source solution. OpenNebula is strong, with experience and ready to demonstrate that now is a better solution than OpenStack, Eucalypthus and others. But OpenStack is supported and funded for big international companies.

OpenNebula, OpenStack and others have a continuous quick evolution. In only few months they published a lot of new features and results. They have an aggressive growing and continuous development. It has been demonstrated that Cloud Computing is not the future else it is the present.

It should be clear that EMOTIVE does not want to compete with products as OpenNebula, OpenStack and others. EMOTIVE is a tool to test and research. So all environments created with EMOTIVE are pre-production environments.
