What does the AWS Application Migration Service (MGN) automate during the migration process?

The AWS Application Migration Service (MGN) is specifically designed to automate and streamline the process of migrating applications from on-premises infrastructures or other environments to AWS. One of its key functions is to handle server discovery, which identifies the servers that need to be migrated. This is a critical first step that helps to define the scope of the migration.

Once the servers are discovered, MGN automates the replication of these servers to the AWS cloud. This replication involves copying the server data efficiently and securely, ensuring that the application can be restored in AWS with minimal manual intervention. Finally, MGN automates the cutover process, which is the final switch from the on-premises server to the AWS server, allowing for minimal downtime and a smoother transition.

The combination of server discovery, replication, and cutover automation not only speeds up the overall migration process but also reduces the potential for errors that can occur during manual migrations. This makes the AWS Application Migration Service an essential tool for organizations looking to move to the cloud efficiently.

In contrast, the other options focus on tasks that are either not directly related to the function of MGN or fall outside its scope. For instance, database schema alteration and optimization generally requires different services that deal with database management rather
