Not really, Podman and containerd are two different technologies, although both allow you to move away from Docker for various reasons (smaller CPU, memory footprint, better security etc). If you are invested into Red Hat container stack, podman makes more sense. However containerd is more universal.

K8s is already moving away from docker, and directly into containerd. Most recently they deprecated dockershim, and users now need to switch to containerd (since docker also uses containerd under the hood, and it doesn't make sense for the orchestration system to run a monolithic service like docker where it just need to launch the workloads)

Some reference links of k8s or PaaS build on top of k8s moving to containerd

- https://kubernetes.io/blog/2018/05/24/kubernetes-containerd-...

- AWS Fargate: https://aws.amazon.com/blogs/containers/under-the-hood-farga...

- Azure kubernetes service (AKS): https://docs.microsoft.com/en-us/azure/aks/cluster-configura...

This driver is similar to what CRI-containerd is doing in kubernetes (if you are coming from the k8s world)
