But frankly, it seems it's still a lot of work to build OSM into your own website/app, setting up your own tile server.
I know there are instructions for this [1] [2] -- but to really get popular, it seems like there really ought to be up-to-date, auto-updating, officially recommended and totally secure server images on Digital Ocean, AWS, Google Cloud and Azure where anyone can spin it up for $5/mo without even ever having to SSH in once (except to update the root password), and then embed a live JavaScript map into their web page with two lines of code -- one to load the library, and one to insert a live map of a given size centered on a given location. Where the whole process shouldn't take more than 10 minutes, and most of that is waiting for the image to be copied to your server.
I've Googled but I can't find anything like that -- with the links below, I assume I'd be using at least a day to set things up, especially since setting up servers from online tutorials never goes smoothly, as you have to google error messages that arise since newer versions have changed slightly since the tutorial was written... And most times where I just want to "throw in a map", I don't want to spend a day+ doing it.
