Apache CloudStack vs OpenNebula
Both stand on cloud management software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Apache CloudStack combines cloud deployment and management with broad hypervisor, storage, and access options. Its self-hosted model and operator security responsibilities are important considerations.
