Cloud computing promises reliable services delivered through next-generation data centers that are built on compute and storage virtualization technologies. Users will be able to access applications and data from a “Cloud” anywhere in the world on demand. In other words, the Cloud appears to be a single point of access for all the computing needs of users. The users are assured that the Cloud infrastructure is robust and will always be available at any time.
What is Cloud Computing?
Cloud Computing is the term given to the use of multiple server computers via a digital network as if they were one computer. The ‘Cloud’ itself is a virtualization of resources – networks, servers, applications, data storage and services – which the end user has on-demand access to. These resources can be provided with minimal management or service provider interaction.
Cloud computing offers the end user resources without the requirement of having knowledge of the systems that deliver it. Additionally, the cloud can provide the user with a far greater range of applications and services. Therefore the cloud enables users and business scalable and tailored services.
Benefits of Cloud Computing:
Cloud Computing brings with it many benefits to the end user. These include:
Access to a huge range of applications without having to download or install anything
Applications can be accessed from any computer, anywhere in the world
Users can avoid expenditure on hardware and software; only using what they need
Companies can share resources in one place
Consumption is billed as a utility with minimal upfront costs
Scalability via on-demand resources
