In this article, the author discusses the application architecture of a food delivery service like Swiggy in-depth with a real-world example. The article talks about different components involved such as order management, payment handling, inventory management, and delivery management, and how microservices can be leveraged to keep the system scalable, available, and manageable. The author also provides an architectural diagram of the application and explains the request-response flow and components involved. This post is useful for anyone looking to understand event-driven architecture, data architecture, and bounded contexts in application architecture.
