Modernizing Legacy Applications To Meet E-Commerce Demands
As a trailblazer in consumer commerce experiences, our customer provides their end clients with comprehensive and efficient services, including cost reduction, scalability and innovative problem-solving. Based on previous engagements, they trusted TEKsystems Global Services (TGS) to perform a data center migration to Amazon Web Services (AWS). TGS recognized that migrating our customer’s monolithic legacy applications to AWS’ cloud computing platform would provide the customized flexibility their end clients expect.
Migrating From On-Premises to AWS
Ordering an Omnichannel Approach to E-Commerce
As a leader in complex digital platforms in commerce, data management and supply chain for over 250 major retailers, our customer oversees manufacturers and distributors worldwide. Their mission? Providing seamless commerce—where their end clients can deliver an efficient digital experience—so consumers find, buy and receive the products they want, when they want and how they want.
With a successful e-commerce platform, modernization efforts ensure their ability to outpace the competition. And while their solution architects manage strategic engagements internally, they acknowledged a successful AWS cloud migration required the insight and support of a trusted AWS partner.
Enter TGS, an AWS Premier Tier Services Partner. When it comes to our AWS approach, we build, modernize and innovate—exactly what our customer ordered.

AWS Three-Tier Architecture
Scalability: A Repeatable Framework
Improved customer experiences and new revenue streams were top of mind as we learned the ins and outs of our customer’s business objectives. Through discovery calls with their clients, it became evident that a universally applicable architecture would be beneficial. Think: scalability.
TGS identified a traditional three-tier AWS architecture consisting of presentation, business logic and data tiers—enabling scalability, modularity and flexibility in software development. Using this method, our team created a repeatable framework that could be used across the project for many different end users, which helped execute the AWS cloud migration successfully.
We started by migrating commerce applications from on-premises to AWS and updated the infrastructure from data centers to AWS’ cloud-based environment. Next, we prepared end clients for the move.
By mapping a plan to migrate commerce applications, platform and infrastructure to AWS, our team provided a thorough AWS migration plan. The framework saved time and increased cohesion.
