Citi Commercial Cards API Platform: Our Event-Driven Microservices Adoption Journey

Senior Vice President and Head of Commercial Card API’s Balaji Rengarajan shares the story of how a microservices platform architected for growth, has over 18+ months successfully scaled from handling thousands of requests a month to millions of requests a month - and they’re not done yet! At its heart is an architectural vision that stresses simplification through standardisation, operational excellence through observability, and cloud-scale through containerisation.
Balaji has 20+ years in Financial Services Technical Architecture and brings to bear his experience and lessons learnt from a number of technologies and use-cases as part of building out this new API platform, adopting best-of-breed technology and architectures.
