LGB Bank: Application Integration in a Large Global Bank

This case study is organised into five parts, meant to be read and discussed progressively. Winston Mariota, a newly hired IT Architect at LGB Bank, had developed over his career a specialisation in Enterprise Application Integration (EAI). Prior to joining LGB, Mariota had recent successes in a smaller regional bank where he had replaced its outdated point-to-point style of integration with a hub-and-spoke style of integration. This enabled the bank to better manage its existing applications, and to easily add new applications with minimal disruption to operations.

Mariota was headhunted by LGB and offered a job based on his expertise in application integration and reputation as a problem solver. LGB specifically wanted him to review its current IT architecture and to propose a new architecture, similar to what he had implemented in the past. Even though LGB was a larger bank with larger integration problems, Mariota decided to take up the challenge. He accepted the job offer to join LGB’s technology department based in Singapore.

This case study gives an opportunity for students to learn about the real-world implementation of Service-Oriented Architecture (SOA) in a large global bank (LGB). Leading into the actual incident, the case first covers the evolution of SOA at the bank, taking a phased approach where students can understand the problems and benefits at each phase of the SOA journey.
