Cloud Migration for a Growing Enterprise
A financial services firm moved 100 servers to AWS using dependency mapping, phased migration, and a multi-account design.
A cloud move shaped around the business
A smaller financial services company needed to move 100 servers out of its legacy environment. Maintaining that infrastructure was becoming increasingly complex, and leadership wanted a clearer picture of operating costs before committing to a new platform. The team also needed room to grow and a stronger recovery plan.
Techhands worked with the client to define the migration around those concerns. Moving the servers was only part of the assignment: the new AWS environment had to support existing applications, preserve their connections, and be manageable for the people responsible for day-to-day IT.
Map the dependencies, then plan the move
Techhands used the client's configuration management database (CMDB) to map application dependencies and understand which servers needed to move together. That helped establish the migration sequence and identify connections that required attention before a workload could leave the old environment.
Alongside the technical assessment, the team developed a cost model around AWS consumption and billing. This gave the client a basis for comparing the planned environment with its existing costs and understanding how spending could change as demand grew.
The migration was organized into waves, with timing coordinated around business operations. This made the work easier to control and gave the teams a structured way to review each group of workloads before progressing to the next.
Build the AWS foundation and migrate 100 servers
Techhands established a multi-account AWS architecture using landing-zone principles and the AWS Well-Architected Framework to guide the design. Separating workloads and operational responsibilities gave the client a more organized foundation for security, management, and future expansion.
Amazon EC2 provided the compute platform for the migrated server workloads. Rather than treating each server as an isolated move, Techhands used the dependency mapping to coordinate the applications and supporting services that needed to function together.
AWS Elastic Disaster Recovery supported the recovery design, giving the client a way to recover server workloads in AWS. Recovery planning was part of the migration work, so the new platform addressed business continuity as well as production hosting.
A simpler platform to operate and build on
The project moved 100 servers to AWS and reduced the client's reliance on its legacy infrastructure. The multi-account design created a clearer operating structure, while the cost planning gave the team a better basis for reviewing consumption and making future investment decisions.
For the client, the value extended beyond a new hosting location. The environment was easier to manage, recovery had a defined place in the architecture, and capacity could evolve with the business. With the migration complete, the team had a foundation for improving applications over time instead of carrying the same infrastructure constraints into its next stage of growth.
