Hi All,
This diagram provide a basic visual representation of how Kubernetes resources such as nodes, pods, load balancers, and persistent volumes can be distributed across different availability zones to ensure high availability and fault tolerance within a Kubernetes cluster.
- Kubernetes master nodes are distributed across multiple zones to ensure high availability at the control plane level.
- Worker nodes (compute instances) are spread across different availability zones.
- Pods, which encapsulate the application's containers, are deployed on the worker nodes in each AZ.
- A load balancer distributes incoming traffic across the pods running in different AZs, ensuring load distribution and fault tolerance.
- If we were to implement a microk8s cluster for the IFSCloud remote environment, what variances would exist compared to the diagram below?
- What are the architectural distinctions between the provided diagram with IFSCloud ?
- If I were to deploy a 3-node cluster for the IFSCloud remote environment, would all 3 VMs necessarily function as masters, or is it possible to designate 2 VMs as workers?
- What challenges are involved in designing kuberneties cluster solution for ensuring availability at the zone level for IFSCloud?. (Network Configuration / Security)
