Cloud Hosting Technique
provides the hosting services in the form of a single virtual machine and is implemented through the use of cloud computing and cloud architecture. It dynamically distributes data and processes across the small servers of the system for processing. The cloud hosting system is divided into many virtual machines. The services offered by a loud hosting service provider are located at its premises and these can be accessed by using client software.
The cloud hosting allows the users to get their applications up and running much faster and enables the quick readjustment of virtual resources to meet the dynamic demands like increased data rate, traffic size and storage requirements. The users can assess the cloud using different client devices like desktops, laptops, tablets and phones. Some of the user devices require real time cloud computing for running their applications, while others can interact with a cloud application via web browsers. Some cloud applications only support specific client software dedicated for these applications. Some legacy applications are also supported through screen sharing technology. The internet giants such as Google and Amazon are using this state of art hosting technology successfully for their servers.
Cloud hosting can be offered in three different modes i.e. infrastructure as a service(IaaS) , platform as a service(PaaS) and software as a service(SaaS). The basic mode IaaS , offers the services in the form of physical or virtual machines ( computers & other processing devices), raw/block storage , firewalls , load balancing mechanism and networks .The IaaS mode services provider supply these resources from a large deployed pool of resources in data centers andthis also include provisioning of local area networks and IP addresses. The PaaS mode cloud hosting services provider offers a cloud computing platform that include an operating system, programming execution environment, database and server. The PaaS application software can be developed and run on a cloud platform and does not involve cost and complexity of buying and managing the hardware and software layers. The (SaaS) mode cloud hosting services provider install and operate application software in the cloud and cloud users access the software from cloud clients and the cloud platform in this case is not managed by the clients. Clouds hosting can be physically deployed in the form of public cloud, personal cloud, hybrid cloud and community cloud.
Cloud hosting has greatly reduced the website operational cost. In older versions of servers, the clients used to pay for a specific bandwidth irrespective of the traffic on that server. The cloud hosting has tackled this problem through the skillful use of variable costing method, where the cost will increase with the traffic and as the load/traffic reduces the cost will be automatically decreases.
