Level 4 - Multi-Cluster, Multi-Cloud

Enabling Cedana usage past a single cluster!

Now that you've performed checkpoints of some workloads, you can start moving them between clusters (and even between clouds!).

You can register multiple Kubernetes clusters (running on separate clouds or on-prem) via the Monitoring->Clusters view.

Below, you can see that we have a GCP and EKS cluster registered.

To move a workload from one cluster to another, simply select the desired one from the drop-down.

Caveats

Moving between clusters has a few caveats/gotchas.

• While we can support checkpoint/restoring PVs and PV claims, these work best in-cluster and have not been tested between clusters.

• There may be some versioning differences with containerd, runc or the driver version, which require special casing/handling. Check in with us if there's any doubt!

• Our daemonsets need to be installable on your nodes, and we support AL2023 (CentOS 9-based) and Ubuntu 22.04+.
