Borg
2003
2003-2004: Birth of the Borg System
- Google introduced the Borg System around 2003-2004. It started off as a small-scale project, with about 3-4 people initially in collaboration with a new version of Google’s new search engine. Borg was a large-scale internal cluster management system, which ran hundreds of thousands of jobs, from many thousands of different applications, across many clusters, each with up to tens of thousands of machines.
Omega
2013
2013: From Borg to Omega
- Following Borg, Google introduced the Omega cluster management system, a flexible, scalable scheduler for large compute clusters.

Why MicroK8s
Embedded Kubernetes – try a Raspberry Pi cluster
ARM or Intel. Standalone or cluster. Minimal space, maximum edge.
Under the cell tower. On the racecar. On satellites or everyday appliances, MicroK8s delivers the full Kubernetes experience on IoT and micro clouds.
Fully containerized deployment with compressed over-the-air updates for ultra-reliable operations.
GPU acceleration
Nvidia auto-detection with CUDA at the ready
Pass GPUs to docker apps for deep learning. Define AI pipelines with Kubeflow on your workstation.
We work with Amazon, Azure, Google, Oracle and IBM to simplify multi-cloud GPU enablement. Build and test locally on MicroK8s, then deploy to EKS, AKS or GKE with confidence.
Batteries included
Tracing. Metrics. Service Mesh. Registry.
Prometheus is popular for metrics, so we bundled it. Just like Jaeger, Istio, LinkerD and KNative.
Turn them on or off with one command.
Automatic security updates
Let it roll, or take control
Choose stable security releases only, or try release candidates, betas and daily builds. MicroK8s can update automatically, with rollback on failure.
Stick with a major version, or follow the latest upstream work. Go with the flow, or take control in the enterprise to specify versions with perfect precision.
Safe and easy CI/CD
Docker app developers love pipelines
So your CI/CD machine spins up a clean VM for each test run? Just install MicroK8s at the top of your script for a crisp, clean K8s to run your tests.
