Cloud computing (Pay-per-use)

With the growth of the Internet, mobile applications and many multicultural communications, it is

important for people to be able to access and understand information in many different languages

quickly. These information resources with a diversity of different languages are distributed in Web

pages and the databases. Cloud computing offers these resources for users in "Cloud" through the

Internet pay-per-use basis. The term Cloud refers to a Network. We can say that Cloud is something,

which presents at remote location. Cloud can provide services over all networks such as, WAN, LAN

or VPN. Applications such as E-mail, web conferencing, Customer Relationship Management (CRM)

etc implement on cloud computing.

Cloud Computing deals to manipulating, configuring, and accessing the hardware and software
resources distantly. It also refers online data storage, infrastructure, and application. From a user's point of view, a good cloud computing defined as using Web applications and/or server services that we pay to access rather than software or hardware that we purchase and install.

Cloud Computing includes data, application and storage and also provides these three basic services i.e.
1. Software as a service (SaaS)
2. Platform as a service (PaaS)
3. Infrastructure as a service (IaaS)

In software as a service model, IT companies provide software services to different customers by

virtualized environment. In platform as a service, companies provide different software development

environment to the user in which they can develop their applications by using the company’s platform. In infrastructure as a service, the user of the cloud uses the physical infrastructure of the cloud providers such as servers, hard disks etc.

The main advantage of cloud computing is that the customer/user pays for what they are using. Pay-as–you-go method is a payment method for cloud computing that charges based on usage in private cloud and amount of storage in public cloud. Some other advantages of cloud computing are as follows:

 One can access applications as utilities, over the Internet.
 One can manipulate and configure the applications online at any time.
 It does not require to install a software to access or manipulate cloud application.
 It offers online development and deployment tools, programming runtime environment
    through PaaS model.
 Cloud Computing offers on-demand self-service.
 It is highly cost effective, it just requires an Internet connection

RBMI is working to ensure that our students are educated about the benefits of cloud computing and
the best way to attach the full potential of the cloud. RBMI conduct consistent IT workshops/seminars
for students which help them to learn new trends and new technologies.
