The best feature is compatible with Amazon EC2. 16 Open Nebula the highest level of customizability that allow users to switch almost every component from the underlying Virtual Machine Monitor (VMM) to the frontend. Open Nebula is suitable in an experimental environment, where one wants to explore every component and crack new results from the computational perspective. 17 Nimbus Nimbus also provides a high level of customization. However, the major portion of customization in Nimbus is available to
