In cloud hosting, a collection of servers are linked to form a larger server resource. People use the term 'cloud' or 'cluster' to refer to the combined servers. This 'cloud' offers all the servers' resources to any user. Features such as memory, power, hard drives and processing speed are shared in cloud hosting. Cloud hosting generally offers better uptime than traditional web hosting since resource usage is handled through many servers, so if one server goes down this often doesn't affect users. With cloud hosting shopping websites don't need to fret over lost customers as a result of site downtime, as the remaining servers will keep a site running if one server stops working. Downtime may still occur due to network glitches in cloud hosting, but these problems are fixed quickly through frequent backups, monitoring and security checking. During cloud hosting compute cycles are measured by the cloud host and these are measurements of how long it takes to process something. In so doing, a cloud host bills users just for the resources they use and need, which saves the users money. When cloud hosts offer a cloud hosting plan, a particular amount of resources is allocated to each plan holder and they are billed based on the resource amount they use. If users use more than their allocation they are billed per GB of bandwidth and data usage. By these means people can drive site traffic and the like in the knowledge that their hosting package will handle it. The ease of scalability is an attractive feature of cloud hosting, as a user can add or remove resources as required without needing to move to a different server. This easy scalability offers to users better control of spending as well as the virtual environment. A business can for example have a dedicated server for their business application while storing and backing up their databases through a cloud host, or test a new website through a cloud host so that it doesn't affect the business's dedicated server. The servers in the 'cloud' can provide access to a range of software and hardware, meaning that users don't need to install this hardware/software. Cloud hosting permits different technologies to be utilised together which wouldn't be allowed by traditional hosting so a UK cloud host for example become an even more viable option. For instance the ability for .php and .asp files to be utilised simultaneously through 'cloud' technologies offers enhanced flexibility for users. If a company outsources its IT infrastructure to a cloud host, it can save physical space on its business premises. Companies would also require less in-house technical staff and have lower electricity bills. Companies can enjoy many resources through frequently upgraded cloud hosting infrastructure without having to do any upgrading themselves as the cloud hosts do the upgrading.
