I’ll discuss many of the issues involved when it requires more than one, ten, or hundreds of machines to service web requests and the battle-tested solutions to allow those systems to communicate together rapidly, redundantly, and securely.

Topics will include:

  • Current technologies for interconnecting systems (Thrift, Protobuf, Memcache, Zookeeper …and more!)
  • Understanding timeouts in the request/response pipeline
  • Redundancy and service discovery
  • Abuse mitigation at large scale
  • Load balancer concurrency and connection rates
  • Dealing with an avalanche of logging data
  • Low level TCP debugging to understand system performance
  • Monitoring and reporting of cluster performance
