Pilot Light Architecture
Build resources around
replicated dataset
Scale AWS resources in
response to a DR event
Keep ‘pilot light’ on by replicating
core databases
Build AWS resources around
dataset and leave in stopped state
Start up pool of resources in AWS
when events dictate
Match required production capacity
through auto-scaling policies
Cut over to the system in AWS
