DynamoDB auto scaling actively matched the provisioned capacity to the generated traffic, which meant that we had a workload that was provisioned efficiently. When the consumed capacity units breaches the utilization level on the table (which defaults to 70%) for 5 mins consecutively it will then scale up the corresponding provisioned capacity units. Provisioners can configure infrastructure, typically virtual machines, either on the local node (that is running Terraform) or the remote machine (that Terraform created).
