Managing web servers can be a lot of work. Especially when it comes to configuring and maintaining SSL certs, server and software updates, etc. Let’s Encrypt has made the SSL part a lot easier, but it is still work and to me feels like overkill for something as simple as a static single-page-application. Especially when there are dead simple solutions like Amazon S3 that can be used to host and scale a static website without any server configuration or maintenance.
