17. SiteGroundThe competitive edge of SiteGround is its expertise in all types of Linux-tailored web hosting, as the company offers great plans for cloud, share, reseller, and dedicated hosting buyers. Carefully tailored enterprise hosting plans will also be available to corporate users, made flexible so that they could meet their specific needs and expectations. A reason why experts often recommend SiteGround are security precautions, as it provides a number of safeguarding measures, including the add-on HackAlert Monitoring ($1/month), the antispam software tools SpamAssassin and SpamExperts, IP address blocklists, and hotlink protection. At the moment, SiteGround hosts over 350,000 sites worldwide. You may also be interested to know that it supports ecommerce applications like Magento, osCommerce, and Prestashop. 
Web hosting services, on the other hand, run servers that are typically assigned only one or a few addresses while serving websites for many domains, a technique referred to as virtual web hosting. Such IP address overloading requires that each request identifies the domain name being referenced, for instance by using the HTTP request header field Host:, or Server Name Indication.
To host a website on the internet, an individual or company would need their own computer or server.[7] As not all companies had the budget or expertise to do this, web hosting services began to offer to host users' websites on their own servers, without the client needing to own the necessary infrastructure required to operate the website. The owners of the websites, also called webmasters, would be able to create a website that would be hosted on the web hosting service's server and published to the web by the web hosting service.
Having multiple servers hosting the same content for better resource utilization. Clustered servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).[9]
