Abstract: A service provider network may provider one or more global cloud services across multiple regions. A client may submit a request to create multiple replicas of a service resource in respective instantiations of a service in the multiple regions. The receiving region of the request may determine the capacities of the multiple regions as to serving respective replicas of the service resource. The receiving region may provide a response to the client based on the determined capacities of the regions.

Abstract: Replicas may be added to a multi-leader replica group for a data set. A new replica may be added to a group of replicas by copying a version of the data set according to a point in time to the new replica. As updates may occur at different ones of the replicas when the new replica is added, updates that occurred at a source replica for the snapshot and other replicas may be replicated by the different replicas according to the point in time at which the snapshot is created without blocking updates at any of the replicas in the replica group.

Abstract: A geographically distributed system using a hybrid, multi-master design is disclosed. The system may use global tables, for which both reads and writes may be performed locally, but with a single region serving as a master region. All strongly consistent reads and writes may be sent to the master region, whereas eventually consistent reads and writes may be performed in any region with a replica. The master region may not be statically assigned but may move from region to region. The master region may be assigned manually by client preference or may be assigned and updated automatically based on the time of day or workload characteristics.
