System design: outside in vs. inside out


Lastly, I think there are strong forces that are pushing today’s developers towards building systems in a way that’s centered around cloud infrastructure. The big cloud providers have nothing to gain from applications being built at an arms length from the infrastructure they make their money off. Instead, they put a lot of effort into marketing their cloud services and describing how to build systems that are tightly coupled with these. I hope this doesn’t come across as conspiracy theory - it’s really just simple market economics: cloud providers sell their services and want you to build applications around them. And you can of course make the most of these services, you just need to view them as tools that you can use to solve specific aspects of your design, and not the first order entities that you build your application around.

And this is the approach we take with Simple IoT.
