Minimal Kubernetes Architecture - 5 VMs at a minimum for complete HA redundancy
- https://kubernetes.io/docs/concepts/overview/components/
- 3 vms running Kubernetes Controllers/Nodes
- 2 vms running adc/layer7 load balancing - This could be as simple as VRRP(keepalived & nginx or hapeproxy) There are commercial offerings of this as well.
- vms live on different baremetal vm hosts so they aren't a point of failure.
Thoughts on platforms and Operators
- All platforms should be portable
- All applications should be migratable.
- You should be allowed to use best of bread and not locked in
- Decisions should be logical and not emotional. Choices need to be logically backed. You and others will feel pain if they aren't
