When users search for your website within the browser on their device, the internet connects the visitor to another computer known as a server, which serves them the relevant webpage. While your website is accessible from anywhere in the world with an internet connection, the physical distance between the server and the geographic location of your website visitors can affect the speed at which this information is exchanged. The further apart the server and the website visitor are located, the greater the latency. Hence the evolution of cloud hosting. Virtual servers are massive computers which store lots of individual servers, often referred to as clusters. These virtual servers are housed in data centres around the world. Together they create an underlying network of high redundancy software and hardware; which results in high availability.
