      Environments
      275 Linux servers
      Vast majority were Red Hat Enterprise Linux 5
      Very progressive Ruby development that was being limited by RHEL5

      Transition
      Rolled out RHEL6 beta for some applications in September last year
      RHEL6 stable released in November. Upgraded everything from beta to stable
      Remaining servers are all being transitioned
    • 4
      New in RHEL6
      Control Groups (cgroups)
      Assign RAM/CPU resources to processes
      RHEV-H and RHEV-M
      Bare metal install virtualisation platform
      Horrible management platform…

      To succeed:
      Infrastructure as Code
      Config management
      Excellent communication between Dev and Ops
      Embed Ops staff in Dev teams
      Don’t use RHEV-M… Yet.
