What Is a Web Hosting Service And How Does it Work?

The term web hosting, more commonly abbreviated as “hosting” means the practice of hosting one or more websites on a web server, accessible over the network and then viewed by online users.

The web hosting is a service provided by millions of companies worldwide who are called “Web Hosting Provider” or simply “hosting provider”. The owners of web hosting allow a website to have a space with certain characteristics (disk space, monthly bandwidth, email accounts, databases and other services). Within this space all web pages, images and general content required for the operation of the website are saved: a domain, such as www.esds.co.in is connected to this space so that the site is publicly accessible.

The web hosting services are hosted on servers, and these in turn reside in particular physical structures called Data Center, designed to have low temperatures and ensure continuity of service, so that websites will always remain visible.

The web hosting providers usually provide different levels of web hosting services that include:

  • Dedicated Server
  • virtual servers
  • colocation web hosting services
  • cloud hosting and applications hosting

How Many Web Hosting Companies Are There?

Currently in India, as well as in the rest of the world, there are thousands of companies that provide web hosting services: the distinction between them is mainly due to the fact that each decides to host their servers in a different nation.

These are real companies that work with staff specializing in providing customer service and maintenance of servers online: this type of activity is not performed with the same quality from all operators, and this leads to a differentiation of solutions and prices in the web hosting market.
