Deployers SHOULD ensure delivery infrastructure has sufficient redundancy to avoid delays due to single points of failure.
Ensure that deployments are resilient to transient failures and single points of failure.
Verify the infrastructure deployment and resilience policies of the Deployer
Infrastructure policy provides for resilience against transient failure
There is no single point of failure, the Deployer's entire infrastructure has redundant failover and robust failure detection.
Single points of failure exist that could be rectified without significant impact to the Deployer's existing operational constraints.
This is a very useful feature. However, its absence is justifiable on the grounds of keeping code or interfaces simple. Justification for not meeting this requirement does not need to be explicit.
