Web hosting is a service which allows websites to be published to the internet and hosted so they are accessible on the around the world on the World Wide Web for everybody to find. Web hosting companies buy or lease many servers in a data center which are connected to the internet, and sell partitioned space on the server, typically called Shared web hosting. This allows website owners to pay a small monthly fee for the hosting space as the cost is spread across many other websites hosted on the same server.
When it's time to set up shop, look for a web host that offers the aforementioned dedicated servers, as well as advanced cloud server platforms (such as Amazon Web Services or Google Cloud), custom server builds should you need it, and 24/7 customer support. Depending on your business' focus, you may need a web host that can handle pageviews or visitors that rank in the high thousands or millions. Many busy hosting plans offer an onboarding specialist that can help you get started, too.
