Concourse announced that they intend to deprecate the current docker-image-resource in the future.
Switch Terraform Dynamodb tables and Vault Dynamodb backend to pay per request
Previously we were still on the default provisioned capacity for our tables. This however led to over provisioned tables and/or autoscaling to be in place. As of now we defaulted to the PPR cost type for internal Dynamodb tables and for the Dynamodb backend for our Vault setup. For application specific tables this is evaluated on a case-per-case basis.
