Working with an Amazon DMS replication instance
When you create an Amazon DMS replication instance, Amazon DMS creates it on an Amazon EC2 instance in a virtual private cloud (VPC) based on the Amazon VPC service. You use this replication instance to perform your database migration. By using a replication instance, you can get high availability and failover support with a Multi-AZ deployment when you choose the Multi-AZ option.
In a Multi-AZ deployment, Amazon DMS automatically provisions and maintains a synchronous standby replica of the replication instance in a different Availability Zone. The primary replication instance is synchronously replicated across Availability Zones to a standby replica. This approach provides data redundancy, eliminates I/O freezes, and minimizes latency spikes.
Amazon DMS uses a replication instance to connect to your source data store, read the source data, and format the data for consumption by the target data store. A replication instance also loads the data into the target data store. Most of this processing happens in memory. However, large transactions might require some buffering on disk. Cached transactions and log files are also written to disk.
You can create an Amazon DMS replication instance in the following Amazon Regions.

Amazon DMS supports a special Amazon Region called Amazon GovCloud (US) that is designed to allow US
government agencies and customers to move sensitive workloads into the cloud. Amazon GovCloud (US)
addresses the US government's specific regulatory and compliance requirements. For more
information about Amazon GovCloud (US), see What is Amazon
GovCloud (US)?
