Cloud computing is a drastic innovation in recent times, which is based on the principle of hardware virtualisation. Cloud hosting, owing to the rapid growth in the industry, has emerged as the order of the day for major IT companies who look to host all their information on a virtual platform ensuring its safety in the case of network malfunctions. A cluster of several servers is partitioned like the CPU, storage and memory, among others. The entire process is managed by a hypervisor, which is a software that acts like a stripped-down operating system across multiple servers. The hypervisor ensures the fact that the hardware and the software layers are independent of each other, thereby, making cloud servers a revolutionary storing facility.
The hypervisor partitions the CPU, memory and storage, and distributes them in such a way that it appear like dedicated servers. However, custom configurations can be created in the operating system, applications, database and network, which provides great flexibility to the customers. Users can alter the size of their server, storage and memory with much ease as the demand varies. With the change in demand, customers can also quickly change the size of their virtual server by adding or removing CPU and memory. The service provider can quickly upgrade, downgrade and disapprove the highly customised partitions and can achieve better economies of scale over shared web hosting with the help of the hypervisor and management tools.
The operations of cloud operators have proved to be more secure over the shared internet hosting. In these servers, users have full control over their shared partition with only the cloud provider having access of the partitioned servers. Individuals can implement customised security policies on their cloud servers. Many cloud computing service providers also support access to virtual servers through VPN or other secure network topologies. Big IT multinational companies invest heavily in virtualisation to manage the hardware and are able to quickly and inexpensively replace the components that have failed in their servers. Microsoft acquired this service to facilitate virtualisation on its operating systems, which is now commonly known as Windows cloud servers. Customers were benefited from this facility immensely, as they were provided with better options at a lower cost, which can be scaled up and down much more quickly than with shared internet hosting.
One of the most glaring disadvantages of shared web hosting is the fact that it usually has a reduced level of security. Since sharing the server with several individuals and entities is risky, security concerns are much greater. Aside from this, shared web hosting creates a problem of limited resources. Since the server is shared amongst many, it is highly likely for one to receive restricted service. Shared hosting does not allow programs to be installed. Since the server is maintained by another individual or company, one does not have the authority of personal maintenance.
