Photon OS™ is a technology preview of a minimal Linux container host. It is designed to have a small footprint and boot extremely quickly on VMware platforms. Photon OS™ is intended to invite collaboration around running containerized applications in a virtualized environment.

• Optimized for vSphere – Validated on VMware product and provider platforms.
• Container support – Compatible with Docker, rkt, and the Pivotal Garden container specifications.
• Efficient lifecycle management – Contains a new, open-source, yum-compatible package manager that will help make the system as small as possible, but preserve the robust yum package management capabilities.
