Create groups from a launch template (in the default subnets unless given),
change their minimum, desired and maximum capacity, replace or remove an
instance, and follow the launches and terminations TheCloud's reconciler makes.
Deleting a group terminates its instances. Scaling policies are not offered:
the runtime stores them but its alarms only drive ECS scaling.
Create pipes from SQS, Kinesis, DynamoDB streams or MSK to Lambda, SQS, SNS,
EventBridge buses or Step Functions, with an optional filter, enrichment and
input template; start and stop them, see the flow with links to each resource,
and send a test message to an SQS source. Sources and targets the runtime's
poller cannot deliver between are refused on create.
