Kubernetes - Rancher

You’re ready to deploy your container-based application at scale with Kubernetes, but at this point you’re faced with a bewildering array of software vendors, cloud providers, and open source projects that all promise painless, successful Kubernetes deployments.

Rancher will help you wade through that confusion.

Rancher is the complete enterprise computing platform to run Kubernetes clusters on-premises, in the cloud or at the edge. 100% open source software with zero lock-in, Rancher fits perfectly with your multi-cluster, hybrid or multi-cloud container orchestration strategy.
