# Migration Services

## Application Discovery Service

* Gathers information about an enterprise's on-premises data centers to help plan migration over to AWS.
* Data that is collected is retained in an encrypted format in an AWS Application Discovery Service datastore.

## Database Migration Service

* Orchestrates the migration of databases over to the AWS cloud.
* You can also migrate databases with one database engine type to another totally different database engine type.

## Server Migration Service

* Can automate the migration of thousands of on-premise workloads over to the AWS cloud.
* This reduces costs and minimizes the downtime for migrations.

## AWS Snowball

* Is a portable petabyte-scale data storage device that can be used to migrate data from on-premise environments over to the AWS cloud.
* You can download your data to the Snowball device and then send it to AWS, who will then upload that to a storage service for you.
