Web hosting refers to the service whereby providers make storage space available on their servers in order to host websites on the Internet. This enables the publication and worldwide accessibility of websites by storing files on servers permanently connected to the Internet.
At its core, web hosting works by providing users with storage space on servers and linking the website's domain to the server's IP addresses via the Domain Name System (DNS). Common services offered by hosting providers include domain management, email provision, website builder, content management systems (CMS), backup and restore, SSL certificates, technical support, database backend, server maintenance and monitoring.
Shared hosting is a cost-effective option that efficiently shares resources between different websites and offers sufficient performance thanks to improved resource availability.
