Cloud and infrastructure
Kubernetes
Clusters designed, built and run with GitOps, monitoring and 24/7 support.
We run production Kubernetes for our own platforms and for clients. These pages cover the distributions and cloud services we work with and the operational pieces, GitOps, storage, ingress, monitoring and upgrades, that turn a cluster into infrastructure.
