Server Migration Service Architecture
The AWS Server Migration Service Architecture is composed of four main components: SMS Connector, Application Discovery Service, SMS Service, and the EBS snapshots or AMIs produced during migration. The SMS Connector interacts with on-premises virtualization environments like VMware, Hyper-V, or KVM, collecting server inventory data and transferring it to the Application Discovery Service. The Application Discovery Service stores, retrieves, and displays information about the servers in the migration project. The SMS Service, built on AWS infrastructure, manages migrations by orchestrating the replication and conversion of server volumes to EBS snapshots or AMIs. The EBS snapshots or AMIs are stored in the target AWS account's Simple Storage Service (S3) and can be used to create EC2 instances.

What is Server Migration Service Architecture?
The AWS Server Migration Service (SMS) is a service that offers a simplified and automated mechanism to migrate existing on-premise applications to AWS.
Why is it important?
Server Migration Service Architecture is important as it provides automatic consolidation of collected server attributes, minimizes downtime, performs automatic replication of live server volumes, and integrates with AWS management console.
How does it work?
Server Migration Service works in several steps. Firstly, it replicates live server volumes to AWS, creates a new Amazon Machine Image (AMI) using this server volume, and launches the Amazon EC2 instance from the AMI. The migration can be tracked using AWS Management Console.
