The check in resource update logic to raise ResourceFailure if a resource is already IN_PROGRESS does not apply for convergence. - In convergence, before acting on a resource we try to acquire lock, hence if a worker is already working on a resource(IN_PROGRESS), another worker cannot start working on this IN_PROGRESS resource. - The scenario a worker would reach the above check is when the lock was forcibly acquired(lets say its worker died). But in this case under convergence, even if the resource status is IN_PROGRESS we need to act on it. Hence removing the above check for convergence.

Heat
Heat is a service to orchestrate multiple composite cloud applications using templates, through both an OpenStack-native REST API and a CloudFormation-compatible Query API.
Why heat? It makes the clouds rise and keeps them there.
