A virtual host service lets you run a server on the internet without owning any physical hardware. Instead of buying and maintaining a real computer, you rent a virtual machine from a cloud provider such as AWS EC2 or DigitalOcean. These virtual machines act like normal computers where you can install software, host websites, and store data. Everything runs inside large data centers, and the provider takes care of power, cooling, and hardware failures.
Virtual host services are useful because they are flexible and affordable. You can start with a small server that costs only a few dollars per month and upgrade it later if you need more storage or memory. This is very convenient for students and developers who want to test ideas or host small projects. In this IS 5320 course project, I used a virtual host service to deploy WordPress and experiment with server configuration in a real cloud environment.
