    is CoreOS' implementation of the App Container specification ("appc") — Designed to be modular/pluggable/extensible, secure, interoperable, natively integrated with init systems and orchestration tools — Still very, very early (0.5.6 is latest release)
  4. What is Photon? — Lightweight, container-optimized Linux distribution created by

    VMware — Designed for use not just as host OS, but also as "container OS" — Similar projects/efforts include CoreOS, Project Atomic (RHEL/CentOS), Ubuntu Snappy Core
  5. What is Vagrant? — A cross-platform, Ruby-based CLI tool for

    streamlining the use of VM environments (creation, provisioning, usage, & decommissioning) — Supports multiple virtualization backends — Great for testing, sharing with others, creating consistent environments — Available from http://www.vagrantup.com
