Delta Air Lines had to move applications to AWS. A simple “Lift & Shift” was not an option as it wouldn’t meet the client’s objective for modernization and cost savings. The client endeavors to move 1,300 applications to the cloud and to modernize 32 core systems to further improve client experience while reducing costs.
The 32 core application systems are mission critical business systems and account for 90% IT costs in billions of dollars.
Delta Air Lines and IBM Consulting needed a fast and accurate modernization and migration assessment for rationalizing applications and migrating core systems using cloud native AWS microservices.
Delta Air Lines chose IBM Consulting as their SI partner for modernizing and migrating applications to AWS.
Delta Air Lines selected CAST Highlight to rationalize the application portfolio of 1,300 applications by automatically analyzing the source code of each of the applications for cloud readiness to migrate to AWS, technical debt, and open-source risks.
Delta Air Lines also selected CAST Imaging to accurately discover the architecture, application dependencies, and inner workings of the top 32 core application systems enabling their modernization.
IBM Consulting used Cloud migration insights from CAST Highlight to determine that 240 applications require Rehosting or Replacing when migrating to AWS, helped further rationalize 200 applications by identifying Cloud blockers to be remediated along with effort estimates. CAST Highlight also identified AWS cloud native services to make the Applications Cloud native.
CAST Imaging helped accurately reverse engineer the architecture of nine applications with detailed views of application inner workings. This essential application intelligence is used to modernize Delta Air Lines core systems using cloud-based AWS microservices.
