Extending Azure Functions with custom handlers

Another benefit of the hyperscale clouds is their operational expertise and their infrastructure design. They can spin up a new server instance in seconds, providing compute on demand. And with container technologies, they’re able to quickly switch in new isolated environments and scale them up as necessary.

That’s where serverless technologies come in, building on those skills and the processes to rapidly launch small, stateless processes as necessary. Like much cloud-native development, these serverless processes are event driven, responding to messages, processing their contents, and passing the results on to the next element of a distributed application. As they’re launched on demand, they can scale rapidly, and as they’re billed per second of CPU time, they’re also relatively cheap when compared to a full-time virtual infrastructure.
