• human-centric
• easy, automated, replication and migration to different datacenter provider
• blob storage replicated generically
• files on the exclusive filesystems replicated via application-aware process, e.g.:
  • asynchronous, but "live" database replication
  • shutdown app then rsync directories
  • ZFS replication and snapshot-ing
• Strengths, Weaknesses, Opportunities, and Threats awareness for all apps
• Not everything needs to start on Nix, NixOs, or with NixOps
• Do not use "Open Core"
  • GitLab
  • Dovcot
  • Zimbra
• LXC containers (not Docker-style)
