A web server is a computer that stores and shares websites with people on the internet. Your website hosting provider needs to run web server software such as NGINX so that visitors can view the web pages on your site.
You can rent out web servers from companies specializing in website hosting. These service providers offer web servers with different capabilities and pricing to meet the needs of a variety of users and websites.
A host can configure a web server in different ways, making it more or less powerful, just like a home computer. The server must have the capacity and features you need for your website.
For example, you need a server with enough space to store your website files. Your needs may change over time, and you can upgrade your web server with more powerful components as needed. At that time, you can choose a hosting plan with more storage space, processing power, memory, and more.
