Container adoption required orchestration. Avoiding cloud lock-in motivated portable infrastructure. Google's expertise in cluster management was valuable to share.

Kubernetes (often called K8s) is a system for running and managing containers automatically. If a container crashes, Kubernetes restarts it. If you need more capacity, Kubernetes scales up. It is like an autopilot for your applications, handling all the complexity of running software across many servers.

Before

Containers (Docker) enabled consistent deployment but managing many containers was manual. Scheduling, scaling, networking, and failure recovery required custom solutions. Each organisation built different orchestration systems.

What changed

Google open-sourced Kubernetes, based on their internal Borg system. Kubernetes provided declarative container orchestration: automated deployment, scaling, and management. It became the de facto standard for cloud-native infrastructure, supported by all major cloud providers.

How it happened

Google engineers (including Joe Beda, Brendan Burns, Craig McLuckie) developed Kubernetes based on lessons from Borg and Omega. It was announced at DockerCon 2014 and donated to the Cloud Native Computing Foundation (CNCF) in 2015. Rapid adoption followed as cloud providers integrated it.

Outcomes

  • Established container orchestration standard
  • Enabled portable cloud-native applications
  • Created ecosystem of tools (Helm, operators, service meshes)
  • Founded cloud-native computing movement

Limitations

  • Steep learning curve
  • Complexity for simple applications
  • Resource overhead
  • Rapid change challenges stability

Lessons learnt

  • Internal tools can become industry standards
  • Declarative infrastructure enables automation
  • Open source + vendor neutrality drives adoption
  • Complexity can be managed with abstractions
