Creating synthetic transaction tests

If a tree falls in a forest and no one is around to hear it, does it make a sound? Or more on topic, if a deployment is broken in a region and no one is awake to use it, does it make a difference? Of course, the answer is yes. We want to be alerted about the broken deployment so that it can be fixed before normal traffic begins. To enable this, we need to continuously pump synthetic traffic through the system so that there is a continuous signal to test. This recipe demonstrates how to generate synthetic traffic using cloud-provider-agnostic, third-party services.
