  7. Container Image Dependencies Application Code Containers encapsulate application code and

    all dependencies. Applications can be depend less on the infrastructure where it runs. • In traditional IT environments, applications needed specific infrastructure. Dependencies needed to be installed beforehand. • Containers incorporate applications and their dependencies so deployment to development, test, and production can be made easier. • Don’t need to be dependent on on-premise, private or public cloud environments. What are Containers?
  8. Fast Simple and Fast compared to VMs. Can be started

    in just a few milliseconds. Portable Can be run in a many environments. Efficiency Low overhead. Resources use by containers can be limited. Why Containers?

  31. Google confidential │ Do not distribute Services A group of

    pods that work together • grouped by a selector Defines access policy • “load balanced” or “headless” Gets a stable virtual IP and port • sometimes called the service portal • also a DNS name VIP is managed by kube-proxy • watches all services • updates iptables when backends change Hides complexity - ideal for non-native apps Virtual IP Client
