Cloud has become a cornerstone of IT transformation for many enterprises. Yet moving to the cloud is rarely as straightforward as expected. According to Gartner, by 2028 nearly 25 percent of cloud initiatives will fail to meet their intended goals due to premature execution and unmanaged complexity early in the process.
The challenge often becomes clear once migration begins. Application dependencies surface, risks increase, and IT teams must keep systems running without interruption. To address these challenges, many organizations are turning to cloud modernization services to structure the migration process and prevent legacy bottlenecks from simply shifting into a new cloud environment.
Why Traditional Migration Is No Longer Enough for Modern Enterprises
Traditional migration approaches are increasingly struggling to keep pace with modern IT environments. Slow processes, heavy reliance on manual work, and limited scalability raise the risk of downtime when applications are moved. At the same time, business expectations continue to accelerate, making legacy migration methods more of an obstacle than a driver of transformation.
Because of this, many enterprises now view migration not just as a technical move, but as part of a broader modernization strategy. Cloud modernization services help organizations execute migration in a more structured way while laying the foundation for future innovation in the cloud.
However, strategy alone is not enough. Enterprises also need tools that can handle migration at scale without disrupting ongoing operations.
AWS Application Migration Service (MGN): A Faster Way to Start Application Modernization in the Cloud
To address these needs, AWS introduced AWS Application Migration Service (MGN), an automated solution designed to simplify application migration. The service allows enterprises to move workloads to AWS without interrupting existing operations. AWS MGN replicates servers from multiple source environments and launches them in AWS through a fast, low risk cutover process, enabling a smoother transition to the cloud.
This migration becomes the first step in a broader application modernization journey. Without requiring architectural changes at the beginning, AWS MGN simplifies workload relocation while opening the door to deeper modernization efforts later. This approach is supported by three core capabilities that keep the migration process stable and predictable.
Lift and Shift as the Starting Point for Modernization
AWS MGN supports lift and shift migration through rehosting, allowing applications to move from physical infrastructure, virtual machines, or other cloud platforms without major architectural changes at the start. Servers are replicated automatically into AWS so workloads can run with configurations similar to their original environments. This approach accelerates migration while giving enterprises the flexibility to pursue modernization in later stages.
Data Protection During Replication
During migration, AWS MGN continuously replicates data directly into the organization’s AWS account through background replication mechanisms. This ensures data remains under the organization’s control and stays synchronized until the final cutover occurs. The process helps maintain data integrity and reduces the risk of loss or inconsistency during transition.
Early Visibility into Application Performance
Once applications are running in AWS, teams can leverage monitoring capabilities to gain clear visibility into resource usage, application performance, and workload status. This visibility allows IT teams to maintain system stability after migration while identifying opportunities to optimize performance in the new cloud environment.
Four Ways AWS MGN Makes Cloud Modernization Easier
In the context of cloud modernization services, migration is more than simply moving applications to the cloud. The process must be stable, efficient, and capable of supporting further modernization. AWS MGN plays a key role in enabling that transition. Here are four ways it helps enterprises move forward more effectively.
1. Faster Migration Across Diverse Infrastructure
AWS MGN allows applications to be migrated from multiple environments, including physical infrastructure, virtual machines, and other cloud platforms without significant architectural changes. This capability helps enterprises accelerate migration while maintaining system consistency during the transition.
2. Enabling Modernization During Migration
Migration does not need to be separate from modernization. With AWS MGN, organizations can introduce adjustments such as disaster recovery configuration or operating system and licensing changes during the migration process itself, allowing modernization efforts to begin earlier.
3. Maintaining Operational Stability During Transition
Through background server replication, applications can continue running while migration is underway. This approach allows enterprises to move workloads without disrupting ongoing business operations.
4. Reducing Migration Complexity and Cost
AWS MGN uses a unified toolset to handle multiple migration requirements. This simplifies workflows, reduces technical complexity, and helps enterprises keep migration costs under control.
