  • Galera Cluster

  • netcat
  • curl
  • rsync
  • ssh

  • load balancing
  • MySQL replication
  • scale up vs scale out
  • identifying and removing SPoF
    • We run hundreds of VMs using KVM on company owned hardware. You should be familiar with hardware selection, configuration, deployment, and monitoring. Additionally, you should understand how to evaluate system and network performance, both physical and virtual, including all of the following:
  • IOPS
  • memory usage
  • cpu usage
  • memory overcommit
  • CPU overcommit
  • bandwidth usage
  • network latency

  • HTTPS
  • TLS
  • Disk encryption (LUKS)
  • network hardening
  • service hardening
  • web application hardening

    • Once you are up to speed, you will particpate in a rotating 24x7 production support role.

  • Flat organization where ideas are sought and accepted from everyone
