LGB Bank: Application Integration in a Large Global Bank (Part 1)

Case Solution

This case study is divided into five parts that should be read and discussed one by one. Winston Mariota, a newly hired IT architect at LGB Bank, had developed a specialization in Enterprise Application Integration (EAI) throughout his career. Before joining LGB, Mariota had recent successes at a smaller regional bank where he replaced the outdated point-to-point integration style with a central radio integration style. This allowed the bank to better manage its existing applications and easily add new applications with minimal business disruption. Mariota was hired by LGB and offered a position based on his experience in app integration and his reputation as a problem solver. LGB specifically wanted me to review the current IT architecture and come up with a new architecture similar to the one I had implemented in the past. Although LGB was a larger bank with significant integration problems, Mariota decided to take up the challenge. He accepted the job offer to join the Singapore-based LGB tech division.
