I may be overly simplifying working with a file, but I'd still argue you're over-complicating it :P You're hitting on a good point with Lambda though, namely the stateless aspect. To get the most out of Lambda, you have to adopt a more Functional-based programming model. > Once you move beyond a single region on a single account, things get a lot harder. I could see that. I'm working in IoT, primarily connecting lots of dumb devices to small translation layers with minute data massaging along the way. In this type of low-intensity environment, the flexibility Lambda (AWS in general) gives you is tremendous. The second performance(/latency) becomes a primary concern, it's easy to see that trade-off become untenable.
