A website built with sites115 can be deployed anywhere docker is used. A quick search on Google would reveal tutorials about docker.
The dockerfile needed is included with the generated site.
This project has been tested on Google Cloud Run
Static sites can be mixed with dynamic sites. To do this put the dynamic site on a sub-domain.
To analyze traffic, you can use a tool like Google Analytics.
Such tools are good because traffic should be analyzed after the page has been served than before.
This refers to a method in which after your site has been pushed to git, it would then be forwarded to the Cloud Host. This is very comfortable.
Always use hosts that support Continuous Integration since a website is always subject to frequent changes.
