Why is Ubuntu the #1 OS for containers?

From Docker to Kubernetes, the experts choose Ubuntu for container operations. The single most important driver of quality, security and performance is the kernel version, and Canonical ensures that Ubuntu always has the very latest kernels with the latest security capabilities. That's why the world's biggest cloud operators and the world's most sophisticated IT operations have chosen Ubuntu for containers.

Kubernetes — the multi-cloud operations layer for next-gen apps

Kubernetes on Ubuntu supports VMware, OpenStack, bare metal and every public cloud.

The new wave of cloud-native applications are being designed for Kubernetes operations. With high performance auto-scaling, healing, service meshes and built-in primitives for CI/CD, K8s is the most significant change in IT operations since the emergence of public cloud in 2009.

VM-style containers for legacy applications with LXD

LXD containers behave like regular VMs, so traditional applications can be installed there unmodified.

Lift-and-shift existing VM workloads

Move your existing Linux VMs straight to containers, easily, without modifying the apps or your operations. LXD's machine containers operate just like virtual machines.

25% faster than legacy VMs

Use VM-style commands to run your applications in an unmodified Linux operating system, at incredible speed, with zero latency.

10x the density of ESX

LXD's pure-container approach to Linux virtualisation offers dramatic density advantages over VMware ESX and Linux KVM for private and public cloud infrastructure.
