Case Study
Migrating legacy infrastructure to the Cloud with an end-to-end analysis and migration solution
THE CLIENT
A trusted, longstanding Fortune 50 technology leader in the global cloud platform sector with over 1 million employees
CHALLENGE
Continual unsurpassed levels of performance require modernization
An overarching goal of reinventing productivity, business processes and building a world-class intelligent cloud platform required this global technology leader to modernize and migrate legacy build systems for optimal change management, efficiency, and performance. With over 13,000 build pipelines containing non-standardized components that required time-consuming manual migrations, they partnered with UST to develop a solution that addressed their goals including automation, governance and compliance while reducing time and expense.
TRANSFORMATION
Automating Discovery, Analysis and Migration
UST first created a DevOps release pipeline to perform end-to-end migration for a specified list of products and leveraged it to address the client’s lack of insight into its legacy system and configurations that were overly complicating migrations. UST then pioneered a custom forensic analyzer for automated inventory analysis of all build definitions in the legacy tool and to size-up inventory via pattern matching and dependency checks to identify all non-standard builds. The client could now perform automated inventory analysis of all build definitions in the legacy tool.
Due to widespread non-standardization in the legacy system, the analyzer tool initially ran on all installed systems which led to discovery of underlying complexity within the legacy system including infrastructure and cloud services dependencies. Harnessing the build system rather than a new web-based platform to perform migrations and force standardization, UST was able to leverage the client’s proprietary API to auto-generate YAML & classic build definitions thereby expanding future scalability. The final solution was easily adapted to the client’s security and compliance frameworks to automate the performance of seamless migrations and address disaster recovery requirements.
IMPACT
A resilient and Agile Cloud Infrastructure
Designed to be intuitive, user-friendly, repeatable, and debuggable the custom solution included enhanced tools for automated build tracking, reporting, and validations to ensure build quality regardless of migration schedules. In addition, automating unit tests spotted easily addressable implementation errors prior to migration that ensured sync between legacy and target systems. The resulting solution supported a reduction in migration time by months while increasing ROI through a standardized, custom and automated process.
