Setting up DMS
To start a DMS task, we need to configure the DMS environment. This involves creating a replication instance, as well as the source and target endpoints, and setting up the task itself with the transformation rules we want to apply. The first component we must create is the replication instance.
Replication instances
A replication instance is an EC2 instance that's preconfigured with the DMS application code. Its role is to provide compute resources to any data conversions that need to be handled, as well as store data that's ready to be applied during a CDC mode task. The replication instance can handle multiple tasks simultaneously and can be sized according to your needs. You can monitor the performance and resource usage of a replication instance while tasks are running to help you assess whether the instance is sized correctly. You can also have multiple replication instances per account, but only one can be assigned to a task at once; there is no...
