This course is manageable with consistent effort. It covers partial discrete mathematics, an introduction to linear equations, and is segmented into: (1) Boolean algebra and logic circuit design; (2) number systems and data representation; and (3) functions, linear equations, vectors, and matrices. Based off this course, I made a web application to assist in learning.

I hope your head is not spinning. Now you might think, Wait, I have a Flask or my Django app where the framework is taking care of the endpoints in my python code. Do I need to recreate several lambdas? A valid question. Luckily, there is also an awesome Plugin for that.

> 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 need it to run it myself? Not really.

Many – most? – AWS products tend towards this analysis. S3 is so locked in that, what, we now have multiple very high quality alternatives that are API compatible?

The real risk of cloud vendor lock in, from where I sit, comes from egregious pricing models that make it cheap to get data in & expensive to push data out. But I'm not sure Cloudflare has the juice to make this play work: egress pricing is essentially free money for AWS, so they've got lots of room to cut costs there – from what I've heard from people who negotiate real bills with AWS, they're very happy to give you discounts there.
