If you use a tool like the Serverless Framework, you can "cobble together the moving parts" and store it into GitHub and make it easily deployable into the cloud. Putting together pieces is what software development is. If you are used to OOP this is even more relevant as the entire idea of OOP is to create discrete pieces of code and compile them together.

PHP for example used to be a "big patchwork" of seperate files working together, but the right tooling came along to think of it as "a unified system". Same thing with Serverless and the Serverless Framework
