Netcraft has developed a technique for identifying the number of computers rather than IP addresses acting as web servers on the internet, and attributes these computers to hosting locations through reverse DNS lookups. This provides an independent view with a consistent methodology worldwide on the numbers of web servers, the rate of growth over time, and the operating systems and web server technology used at each hosting company worldwide. The dataset is useful to hosting companies for competitive analysis, mergers and acquisitions, identifying international markets for organic expansion, and also to any organisation selling to the hosting industry. One of the common observations made about the Web Server Survey is that it counts hostnames rather than physical computers, and so is not a suitable metric to indicate the number of servers a hosting provider has. To build up sufficient certainty that IP addresses on the same computer have been identified, many visits to the sites in the Web Server Survey are necessary, which takes place during a period of over a month. The survey does not attempt to count back-end servers application or database servers or servers other than web HTTP servers. If one wants to use the survey as a way of measuring the total number of servers that a company has supporting its web presence, the survey would produce a lower number because it counts only the web servers.
What is a Server?
Server hosting solutions move the cost of hardware maintenance and personnel to a cloud setting.
Many terms related to computers and the Internet are used casually or incorrectly, which can make a technical topic challenging to understand. However, with a functional understanding of how the Internet works, the context to make decisions on subjects such as server hosting becomes much easier. The computers used by individuals to access the Internet and use programs to communicate with others, whether in a consumer or business context, are generally desktop computers, laptops, and mobile devices. Servers are a specialized type of computer engineered to operate at a consistent performance level hours a day for extended periods of time. They run a specific kind of operating system and can be used by one particular organization as a single-tenant server, or for resellers as a shared server. There are other categories as well, such as virtual servers and cloud servers. All can do a set of jobs related to running the Internet. Most web servers operate in large racks alongside dozens or hundreds of other servers in a data center, where they store different kinds of data. The server hosts the data for others to access. Except for some of the largest companies in the world, such as Walmart and Apple, most organizations have servers with their data in the same data center as many other organizations.

Opting for a dedicated server means that you get an entire server to yourself. Shared web hosting can appear to be amazing value, with feature-packed products available for just a few pounds every month. But the reality is often very different, and they're not always the bargains they seem.
Server hosting is an infrastructure delivery model that provides IT users with remote access to server resources CPU, Memory, Disk, etc. There are many benefits to server hosting , including, but not limited to, faster setup time, monthly payments instead of large capital expenditures, and ongoing upkeep so you can focus on your business as opposed to routine infrastructure maintenance. The legacy process of ordering and shipping servers to your office or data center often takes weeks, if not months. In many cases, however, hosting providers can deploy, configure and make accessible servers for remote access within minutes of ordering. Server hosting allows you to avoid large capital expenditures for hardware that depreciates over time. Instead, you simply pay a monthly server hosting fee to access the resources remotely. The payments cover things like break-fixes and other important aspects of server hosting such as the space, power and cooling the server uses. The monthly payments also include bandwidth usage.
