+## Managing Costs (off of Lambdas) and Scale-to-Zero
+
+I had some questions before and after last class about how to achieve a
+serverless effect, or in other words, how to create and dispose machines as
+they're needed.
+
+Fly.io has a concept called [Machines](https://fly.io/docs/machines/) that can
+be started and stopped on demand, in addition to GPU machines available. These
+can be triggered via API, which means you can use your other server to trigger
+starting and communicating with a machine like this.
+
+## Aside - Lower-tech Versions of Course Technologies
