OpenStack

OpenStack is an open-source cloud computing platform that provides infrastructure-as-a-service (IaaS) capabilities for deploying and managing virtual machines, networks, and storage at scale. Originally launched as a joint project by NASA and Rackspace in 2010, OpenStack enables organizations to build private and public clouds using commodity hardware, with KVM as its most widely deployed hypervisor. The platform is not a single monolith but a constellation of interoperable services — Nova for compute, Neutron for networking, Cinder for block storage, Keystone for identity — each governed by its own community and release cycle. This modular architecture is both OpenStack's strength and its curse: it permits flexibility and vendor independence but imposes integration complexity that has driven some users toward proprietary alternatives like VMware vSphere or managed Kubernetes platforms.

— OpenStack's struggle for adoption reveals a pattern in infrastructure technology: the open platform that promises freedom from vendor lock-in often replicates that lock-in through integration complexity. The cost of exit becomes the cost of expertise.
