    Table 1. ECS Cluster Actions and Performance Impact
    ECS Cluster action Affects Availability Impact Speed
    Stop and Start Yes All nodes Fastest
    Restart Least one node at a time Slowest
    Rolling restart (if the agent batch size is 1 then it is similar to Restart).

    Inversely proportional to the batch size.

    		Depends on batch size. Speed is proportional to the batch size.That is, higher the batch size, higher the speed.

Refreshing a Embedded Container Service Cluster
