K8s Orchestrator over Orchestrator

This was how it started, i.e. Kubernetes came into existence as there was a need of container orchestration.

Above diagram depicts the 4 layers:-

1. H/w Layer- H/w comprises of server and storage need to be configured either automated using ironic , BMaaS
2. Virtualization Layer- There was always a Cloud virtualization layer could be Openstack or any Public Cloud
3. Containerization Layer- Then comes majorly the Vanilla K8s layer for container orchestration i.e. lifecycle mgmt, deploy, upgrade, availability, resiliency etc.
4. Application Layer- Microsvcs if containerized have started running on top of K8s infra.

Second picture here now shows how it has been evolved and transformed :-

Infra Management Layers with K8s

Above diagram depicts various Orchestrators:-

• Cluster API- Kubernetes-style APIs to cluster creation, configuration, and management

• Kubevirt -KubeVirt delivers container-native virtualization by leveraging KVM, the Linux Kernel hypervisor, within a Kubernetes container.
