[closed] docker vs local installation

Hi everyone

We have a server with 64gb of Ram, and we want to have our own osm tile server and osm routing server which is also available using docker and can be installed locally, I have following questions regarding that (considering that we are just serving great Britain area)

1) should we use docker or local installation for production usages ?

2) how we can restrict the url https://myserver/{z}/{x}/{y}.png to only our users

3)Is 64gb of Ram enough for both tile and routing services for Great Britain

thanks in advance
