Scaling HTTP Azure Functions
Wednesday, February 15, 2017
One of the promises of serverless computing is automatic scaling based on load. I decided to run some HTTP load tests on Azure Functions to see how well it scales. In particular, how many instances does the function app scale out to? How does load affect response times and throughput? How stable is Azure Functions as it scales out?
Before we begin, I want to point out that this is by no means a scientific test. Take the results with a giant grain of salt.
