AWS Announces General Availability of New Application Migration Service
AWS Application Migration Service (AWS MGN) is a new service that allows organizations to move applications to AWS without making changes to the applications, their architecture, or the migrated servers. The public cloud provider has announced the general availability of this service.
AWS MGN is the successor to CloudEndure, which the company acquired in 2019. CloudEndure includes a migration offering that allows customers to move applications from any physical, virtual or cloud infrastructure to AWS for free. This offering complements another AWS offering called AWS Server Migration Service (AWS SMS), an agentless service for migrating on-premises workloads to AWS.
AWS now ships with a new migration service, which they recommend as the primary migration service for lift-and-shift migrations to AWS. Additionally, according to AWS, the new service simplifies migration by allowing customers to use the same automated process for various applications. Customers can migrate all kinds of applications such as SAP CRM, Oracle E-Business Suite, Microsoft SharePoint, and commercial databases to AWS.
When migrating to AWS, an AWS MGN replication agent must be installed on the source servers, then users can view and set replication settings in AWS MGN console. The migration service will use these settings to create and manage a staging subnet with Amazon Elastic Compute Cloud (EC2) lightweight instances that act as replication servers used to replicate data between source servers and AWS.
Replication servers receive data from the agent running on your source servers and write that data to Amazon Elastic Block Store (EBS) volumes. Your replicated data is compressed and encrypted in transit and at rest using EBS encryption. AWS MGN keeps your source servers up to date on AWS using continuous block-level data replication. It uses your defined launch settings to launch instances when you perform non-disruptive testing or failover.
After users launch test or failover instances, AWS MGN converts their source servers to start and run natively on AWS – and when they are functioning properly, they can decommission their source servers. Finally, they can monitor AWS MGN using Amazon CloudWatch, Amazon EventBridge, and AWS CloudTrail – collecting raw data and processing it into readable metrics in near real time.
AWS cloud competitor Microsoft also offers a migration service. Azure Migrate provides a centralized hub to assess and migrate to Azure on-premises servers, infrastructure, applications and data.
Migration services are essential to allow economies of scale to work.
Currently, AWS MGN is available in US East (N. Virginia), US West (Oregon), US East (Ohio), Asia Pacific (Tokyo), Asia Pacific (Sydney), Asia Pacific (Singapore) , Europe (Ireland), Europe (Frankfurt) and Europe (Stockholm) Regions. Customers can use the service free of charge for 90 days for each server they want to migrate and only incur charges for AWS infrastructure provisioned during migration and after failovers, such as compute (Amazon EC2) and storage resources. (Amazon EBS). Also, price details are on the pricing page.
