That's a mouthful.
If you were to really only deliver some HTML, it's overkill. For this reason, my blog is hosted with an old-school 90s-style FTP-backed "webspace" provider.
But the architecture described is used to develop-build-deploy a full-flegded web-based application, with a persistence layer for user data and a potentially complex user-interface.
And for this, having a sound architecture and tech-stack where you do not need to care about low-level server issues is, while certainly not a silver bullet, quite a productive experience.
