As we transitioned our platform at Tesco from a monolithic to a microservices-based architecture, we encountered a critical challenge: ensuring transactional consistency across numerous subdomains. Neglecting this aspect risks leaving the system in an inconsistent state, directly impacting business operations and customer satisfaction. This session aims to share insights gleaned from the ground-up construction of the Tesco retail platform, which handles millions of orders and customers every day. Join Prajwal delve into this challenge with practical examples and assess various design strategies for orchestrating transactions across multiple microservices.

By attending this talk, you'll gain a deeper understanding of the complexities involved and empower yourself to address this concern from the inception of your system designs. While no universal solution may emerge, expect to explore multiple options tailored to diverse use cases. This interactive session invites participants to seek clarity, question assumptions, and draw valuable lessons from real-world implementations.
