> But two years from now CloudFlare could be doing the exact same stuff Amazon is doing now, and customers are locked in again, because no source code. I hear this argument often but it always rings hollow. A friend had a first gen iPod – when he wanted to switch, he discovered that the music he bought on iTunes couldn't be moved anywhere else because of DRM. That's lock in. But this morning I was looking at the source code of an app built against the Serverless framework[1] and what I'm seeing is a bog standard WSGI application that uses a library to transform the inbound AWS "proprietary bits" into WSGI[2]. I'm not worried about lock-in there because all API Gateway + Lambda do is "translate an HTTP request into a JSON object and toss it to an app"[3] – what source code am I missing? The underlying Lambda/APIGW code? OK, but do I ne

Serverless is fantastic for event-driven workloads at arbitrary scale. There are definitely some things to learn about serverless runtimes, but beyond that there isn't much complexity aside from the large hill to climb which is understanding IAM. Here are a lot more examples: https://github.com/serverless/examples And if you'd rather define the infrastructure side as code vs YAML, you might want to check out Pulumi as well: https://github.com/pulumi/examples

Have you seen this npm package? https://www.npmjs.com/package/serverless-offline I have no idea if this exists for other languages but its what lets me develop and test my functions locally before deploying them to stage/live. Edit: they have some good examples - https://github.com/serverless/examples/tree/master/aws-node-...

If using NodeJS there is a very similar package to zappa called Serverless https://serverless.com/ One thing I would improve with the authors article is he crammed a giant conditional statement on the http-method inside his one function. Serverless makes it easy to bundle a single function per HTTP method and even share common code between them. You can build out a whole application as a single npm package. Bonuses include plugins for serverless that let you unit test your handlers, run a simulated APIG/Lambda/Dynamo environment locally for development, plugins that let you interact more deeply with AWS like assigning a custom domain to your APIG.
