Pub-Sub vs Request-Response: Which Architecture Should Your Microservices Use? (opens the original)
Read excerpt
Every microservices system eventually faces the same decision.Service A needs to tell Service B that something happened. How should it do that?The naive answer is a direct HTTP call.

How to Design a Food Delivery Service Like Uber Eats or DoorDash (opens the original)
Read excerpt
Most engineers look at a food delivery app and think: ride-sharing with food attached.That assumption is the fastest way to give a shallow answer in an interview.Ride-hailing is a two-sided marketplace — match a rider to a nearby driver and the trip begins the moment the driver arrives. Food delivery is a three-sided marketplace: customer, restaurant, and driver — and it inserts a production step that nobody on the platform controls: the restaurant has to actually cook the food.That cooking step
