Container Runtimes & Orchestration

The runtime layer decides how your code runs in production: as a container, a pod in a cluster, or a process on a bare VM.

Why this layer matters for sovereignty

  • Orchestration is the layer that makes your deployment portable: a container image runs the same way on any European cloud — this is what keeps infrastructure providers swappable.

  • Small, embedded distributions (k3s, k0s, MicroK8s) make Kubernetes viable on a single node, not just for platform teams.

  • PaaS offerings on European infrastructure give you the abstraction without the cluster to run.

What to look for

  • Right-size the tool: a single-node k3s or plain Docker Compose beats a cluster you don't operate well.

  • OCI-standard images (Docker, Podman) keep you portable between all providers.

  • Ecosystem: Helm charts and operator availability determine what you can install in one command.

  • For PaaS: build-pipeline and scaling behavior, and where the build servers physically run.

Frequently asked questions

What is container orchestration?

Container orchestration automates the lifecycle of containers: scheduling them across servers, restarting failed instances, scaling them with load, and rolling out updates without downtime. Kubernetes is the dominant system; Nomad is a lighter alternative, and Docker itself covers the single-host case.

Do I need Kubernetes?

Not necessarily. If you run a handful of services on one or two servers, Docker Compose or a minimal distribution like k3s is simpler and safer. Kubernetes pays off when you run many workloads, need self-healing and autoscaling, or must offer a platform to multiple teams.
