I could not find a tutorial for beginners for how to locate my servers.
For instance I use Compose.io for my MongoDB and DigitalOcean for my Meteor.js app.
Lets say I want to have fast service in Germany. Now the closest I can get to Germany with Compose is London. Should I now place my DigitalOcean backend server close to my DB server in London? Or better place my backend in Germany (DO offers Frankfurt as a location)?
