Deploying a website into your domain is the foundation for your presence on the Web. Control over its content is what makes it yours, the content itself is what makes it represent you.
There are many ways to create and operate a website: from all-inclusive builders like WordPress, to online hosting a Static Website, to self-hosting a fully-fledged web server.
A cheap way to operate a website is to use static website hosting, which is often offered freely by several platforms like GitHub, GitLab, Netlify, CloudFlare, DigitalOcean and many others. In any case, you’re responsible for configuring the website generation with a static website generator tool and the website publishing with one of these platforms.
