There are more traditional tools and SaaS services based around the web-driver model, which might be useful for folks who don't want to get into infrastructure, and don't want the latency of using Lambda. In testing I saw 15s+ for visiting a simple website that took 1-2s locally in a container.

Feel free to give the content a try and let us know how it goes for you? OpenFaaS can also run these tasks async and queue them up / process from a queue.
