When AWS Lambda launched in 2014, it fundamentally changed how we think about infrastructure. No servers to provision, no capacity to plan, no patches to apply—just code that runs when events occur, billed by the millisecond. AWS Lambda Event-Driven Architecture The Mental Model Shift Traditional infrastructure starts with capacity planning: How many servers? What instance […]
