CASE STUDY
Leading Indian e-commerce company fast-tracks cloud migration to AWS with CAST Highlight
The client is one of India's top 10 e-commerce companies, offering a wide range of products like electronics, fashion, and home goods.
CAST Highlight enabled the client to identify application dependencies and plan migrations four times faster, allowing them to migrate all 265 applications to AWS in less than two months.
It took 3-4 weeks instead of 3-4 months to identify dependencies in code and 1.5-2 months instead of 3-4 months to execute the migration. All 265 applications have now been migrated to AWS.

Challenge
The client was experiencing "migration paralysis" due to significant challenges. Over the past decade, they developed 265 applications, making the migration landscape both extensive and complex. The loss of detailed knowledge about these legacy systems complicates decision-making and planning.
Without clear insights into their application portfolio, they struggled to identify where to begin the migration, determine the optimal path for each application (Rehost. Refactor, Rearchitect, etc.), and optimize them for AWS services. Additional risks from open-source components, such as security vulnerabilities, intellectual property exposures, and obsolescence, added to the uncertainty.
These factors stalled their migration efforts, emphasizing the need for a strategic and automated approach to ensure a successful transition to AWS.
Solution
The e-commerce firm used CAST Highlight's automated source code analysis, to swiftly identify where to start their migration journey, determine the optimal path for each application, and optimize them for AWS native services.
They segmented applications for migration and optimization, prioritizing efforts and streamlining the transition.
By automatically identifying cloud blockers in the code (e.g., use of persistent files) and following advice on how to address them, the team proactively tackled migration challenges and enhanced the applications' resource efficiency.
Additionally, CAST Highlight identified intellectual property exposures, security vulnerabilities, and obsolescence risks in the open-source components used by the 265 applications, which was critical for moving them to the cloud.
Results
By applying strategic insights from CAST Highlight’s automated source code analysis, the client swiftly migrated all 265 applications to AWS in less than 2 months.
They achieved four times faster identification of application dependencies and migration planning, expediting the process and eliminating bottlenecks.
The migration execution was completed twice as fast, minimizing downtime and accelerating time-to-value from AWS adoption.
This approach not only saved substantial time and resources but also enhanced application resilience, reduced operational risks, and strengthened the client's cloud infrastructure for future growth.
