Functions as a Service (Lambda, Cloud Functions)

Summary

The core serverless compute primitive — a function that runs in response to a trigger (an HTTP request, a file upload, a schedule) and scales automatically to handle any volume of concurrent invocations.

• 1Deploy a simple function triggered by an HTTP request and test it end to end.
• 2Learn the basic execution model: trigger, invocation, execution, response.
• 3Practice setting a function's memory and timeout configuration appropriately for its workload.
