Hi!

There are a few different ways to do that—I'll list the most common ones. You can:

1. spin up a new Droplet, install, for example, Nginx on it, and apply the default config files that you prefer, and take a snapshot of it. Then, whenever you want to spin up a new web server Droplet, you can just choose the said snapshot and quickly get up and running.
2. use a configuration management software to automate deploying and configuring new servers. Take a look at the following tutorial series:

     3. Configuration Management 101: Writing Puppet Manifests
     4. Configuration Management 101: Writing Chef Recipes
3. use User Data to run a script of your own when the Droplet first boots that installs and sets everything up the way you like it.
