What is the purpose of AWS Application Migration Service (MGN)?

• A. Automates and accelerates lifting and migrating on-premises servers to AWS with minimal downtime.
• B. Migrates databases only.
• C. Provides serverless compute.
• D. Manages code deployments.

Answer: (A)

MGN is designed to automate and accelerate the lift-and-shift migration of on-premises servers to AWS with minimal downtime. It continuously replicates your source servers to an AWS staging environment, allowing you to test the migration and validate workloads without impacting production. When you’re ready, you perform a cutover to the synchronized EC2 instances in AWS, resulting in a very short downtime window. It supports Windows and Linux, handles the initial replication and any needed conversion to AWS-compatible formats, and scales to migrate many servers. This focus on migrating entire server workloads to AWS with minimal disruption is why it’s used for lift-and-shift migrations. It’s not limited to databases, it doesn’t provide serverless compute services, and it isn’t a tool for managing code deployments.
