AWS Lambda is a serverless compute service that can run code in response to predetermined events or conditions and automatically manage all the computing resources required for those processes. Customizing and connecting these services requires code. What is AWS Lambda? Where does Lambda fit in the AWS ecosystem?

It is desirable for a program to be able to go to sleep and then wake up a little while later. The answer is hardware interrupts. The OS programs a timer chip that then triggers an interrupt that wakes up the CPU and the OS can then schedule your thread. Timer interrupts and their raison d’être. Decades of madness.
