CASE STUDY
Global European insurance company expedites cloud migration planning on AWS
The client is a leading global financial services provider, specializing in insurance and asset management. Known for its extensive portfolio, innovative solutions, and commitment to customer trust, stability, and sustainable growth worldwide.
CAST Highlight enabled the client to develop a migration plan for 47 applications in just three weeks, instead of the estimated four to five months.
Analysis of all applications would have taken 4-5 months without CAST; it took 3 weeks with CAST. We saved the effort of 2 people in each of the 4 squads for 4.5 months.
SI Partner working for the client
6x faster
AWS migration planning
55 million
lines of code automatically analyzed across 47 applications
Challenge
The client’s applications utilized aging technologies, such as COBOL, Java, and JSP. Their priority was to modernize the applications developed on COBOL before migrating to AWS.
The entire portfolio comprises over 55 million lines of code across 47 applications using technologies such as COBOL, Java, JSP, JavaScript, and TypeScript.
Without clear insights into their portfolio, the SI Partner working with the client struggled to understand the inner workings of the applications, build their roadmap to the cloud, pinpoint cloud migration blockers in the code and estimate the time needed to address them.
Migration planning was stalled, highlighting the need for a strategic and automated approach to overcome obstacles and transition to AWS successfully.
Solution
By leveraging CAST Highlight's automated application source code analysis, which provides insights into the applications’ inner workings, the SI Partner was able to swiftly categorize the application portfolio into four distinct groups based on cloud maturity and planning needs.
This process involved segmenting applications for AWS migration and optimization, helping prioritize efforts and streamline the transition. By examining detected cloud blockers, guidance on how best to address them, and effort estimates, the SI Partner was able to clearly organize and plan the migration.
They also received automated recommendations on ideal AWS cloud native services for each application to optimize resource consumption post-migration.
Results
By leveraging the strategic insights from CAST Highlight’s automated application source code analysis, modernization and migration planning that was completed six times faster than anticipated.
This comprehensive, insight-driven approach took just three weeks, rather than the estimated four to five months for the SI Partner to deliver the migration plan.
This approach not only saved substantial time and resources but also yielded additional benefits. The application insights provided the client with a clearer understanding of their systems, while the precise identification of cloud blockers offered a detailed checklist for the development team to address before migration.
