Case Study: Delta Air Lines accelerates cloud migration and modernizes core systems with CAST and IBM Consulting

Delta Air Lines rationalizes 1,300 applications with CAST

Delta Air Lines, a major global airline, faced the challenge of migrating 1,300 applications to AWS while also modernizing 32 core, mission-critical systems to improve costs and customer experience. A simple lift-and-shift approach was insufficient. They partnered with vendor CAST and IBM Consulting, utilizing CAST Highlight to analyze their application portfolio for cloud readiness and CAST Imaging to understand the complex inner workings of their core systems.

With CAST, specifically CAST Highlight and CAST Imaging, Delta Air Lines and IBM Consulting gained the insights needed for the modernization. CAST Highlight helped rationalize the portfolio, identifying hundreds of applications for rehosting or replacement and pinpointing cloud blockers. CAST Imaging reverse-engineered the architecture of key applications. The results included millions of dollars saved from migration and modernization costs, and the essential intelligence to modernize core systems into AWS microservices with reduced risk.
