What is AWS Application Migration Service (MGN)?

AWS MGN replicates source servers in real time and automatically converts them into Amazon EC2 instances. It supports a broad range of server types, including physical servers, virtual machines, and cloud-based systems, making it suitable for virtually any migration scenario. One of the key advantages of AWS MGN is the ability to test and cut over with minimal downtime, ensuring a smooth transition without interrupting day-to-day operations.

Core Features that Power Seamless Migrations
AWS MGN delivers continuous, block-level data replication, which captures every change made to the source server in real time. This enables highly accurate and consistent copies of your applications. It also offers automated server conversion and launch on AWS, with the ability to insert pre- and post-launch custom scripts to fine-tune your environment. Large-scale migrations are fully supported, and the service integrates with other AWS tools such as Amazon CloudWatch and AWS Systems Manager for enhanced visibility and control.
Why Choose AWS MGN?
Speed, simplicity, and reliability are at the heart of AWS MGN. Businesses benefit from faster migrations with lower costs and minimal disruption to ongoing operations. Since there is no requirement to modify the original servers or applications, the process is both streamlined and secure. It’s also highly scalable, making it ideal for enterprise-wide adoption. With built-in AWS security and compliance features, governance is seamlessly managed throughout the migration process.
Real-World Use Cases
Organisations turn to AWS MGN in a variety of scenarios. It is a go-to solution for shutting down or consolidating data centres, enabling disaster recovery strategies, and breathing new life into legacy applications. It is also used for urgent migrations, such as when ageing hardware fails or a provider announces an unexpected exit from the market.

How Does It Compare to Other Migration Tools?
‍
AWS MGN replaces older tools such as AWS Server Migration Service (SMS) and CloudEndure, which is now part of MGN’s core offering. Unlike SMS, which required incremental replication steps and more manual configuration, MGN delivers a more automated, real-time experience. It has become the recommended choice for lift-and-shift migrations within the AWS ecosystem.

D55 enabled us to migrate from on-premise to a cloud-based solution, resulting in monthly cost savings of about 40%. Cloud-based systems give us a high level of resiliency and an unlimited capacity to scale. We’ve really put in place the foundations for later phases of work and further cost reduction as we scale. It was a partnership as opposed to a service - we work well together.
