That's basically why we're doing it, and we're seeing some really good costing implications from implementing various things using Azure Functions. Not perfect, but an extremely capable system, and there are things some of our teams are doing with Durable Functions that I was completely stunned by when they explained how it all works. Microsoft have some very good technology there.

The only thing I'm sad about is that you can only host it on Azure. I'd love an open standard for function-like programming and hosting.

Of course, not everything is suitable for this model, and it certainly won't be the most cost-effective or performant way to do it for everything either.
