The following Course will focus mainly on a private Virtual Environment such VirtualBox or VMware Station. However, if you are willing to setup straight on DigitalOcean or Vultr, then you can skip Course1 and jump to Course2. But, I highly recommend to go through Course1 to build In-house local Web Hosting Server for testing or developing purpose. After all, the concept is same on either Private or Public Virtual environment.
