Polaris - guiding the traffic home.

An extendable high availability solution for the data center and beyond, Global Server Load Balancing(GSLB), DNS-based traffic manager.

  • Built as an enhancement for PowerDNS Authoritative Server.
  • Load-balancing methods:
    • Weighted round-robin.
    • Topology(direct clients to end-points in the same region/datacenter).
    • Failover group(active-backup).
  • Parameterized(timeout, interval, retries etc.) health monitors:
    • TCP
      • Connect to a specific port number.
      • Send string.
      • Match regular expression in response.
    • HTTP/S
      • Port number to use.
      • SSL.
      • Request a specific URL path.
      • Expect a response code from a configurable array.
    • Forced
      • Force a member to be up or down, disables health checking.
  • Ability to run health checks against an IP that is different from the member IP.
  • Up to 1024 addresses returned in a response.
  • Different ways to handle the "all-pool-members-down" situation(fallback):
    • Return any configured end-points(ignore the health status).
    • Refuse query.
  • Automatic SOA serial.
  • A single Health Tracker can serve multiple DNS resolvers running on different machines.
  • LB configuration validation on start-up operations.
  • Elastic threads pool serving health checks.
  • Asynchronous, non-blocking comms between the internal components.

See the WIKI for installation, configuration and other information.
