One should refer : Docker file best practicies

Important resources about security : Center for Internet Security (CIS)

If master node comes down, then also the application will be keep running. Yes, during deployment if master node come down then deployment got impacted. 

We should sepeate network for control plane (between master node, worker nodes) and user plane (for pod to pod communication among microservices)

We should have pod restart policy and health check API in plact at pod. 

Munish kept camera icon on right top cornet to indicate picture time. Instead of taking notes, one can take picture of that important slide. 

Generally at VISA deployment the VMs are run with 30 to 40 % of capacity. Containers run with higher capacity.
