david gave a good response. We actually have TWO options (even simpler right? :)). You can just buy a dedicated instance to run on and it will always be hot and running your code. You have to manage scale for that though. You can, more interestingly, also use our "dynamic compute" model where we manage scaling and provisioning everything and we only charge you for the time your CPU was running. This is great for folks who have highly elastic workloads.
