Open Source Cloud Computing
Renting compute by the hour is frictionless until the workload is steady and predictable, and then you are paying a premium for elasticity you no longer use while a hyperscaler's pricing quietly shapes how you architect everything. The open source IaaS and PaaS platforms here let you run your own cloud on your own hardware, so provisioning, scaling, and deploying answer to capacity you already paid for rather than a per-hour meter and a vendor's roadmap.
