CLOUD COMPUTING: THE NEXT BIG THING

1. Introduction:

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a

shared pool of configurable computing resources (e.g., networks, servers, storage, applications,

and services) that can be rapidly provisioned and released with minimal management effort or

service provider.

Cloud computing provides computation, software, data access, and storage services that do not

require end-user knowledge of the physical location and configuration of the system that delivers

the services. Parallels to this concept can be drawn with the electricity grid, wherein end-users

consume power without needing to understand the component devices or infrastructure required

to provide the service.

Cloud computing describes a new supplement, consumption, and delivery model for IT services

based on Internet protocols, and it typically involves provisioning of dynamically scalable and

often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote

computing sites provided by the Internet. This may take the form of web-based tools or

applications that users can access and use through a web browser as if they were programs

installed locally on their own computers.

2. How it Works

A cloud user needs a client device such as a laptop or desktop computer, pad computer, smart

phone, or other computing resource with a web browser (or other approved access route) to

access a cloud system via the World Wide Web. Typically the user will log into the cloud at a

service provider or private company, such as their employer. Cloud computing works on a client-

server basis, using web browser protocols. The cloud provides server-based applications and all

data services to the user, with output displayed on the client device. If the user wishes to create a

document using a word processor, for example, the cloud provides a suitable application running

on the server which displays work done by the user on the client web browser display. Memory

allocated to the client system's web browser is used to make the application data appear on the

client system display, but all computations and changes are recorded by the server, and final

results including files created or altered are permanently stored on the cloud servers.

Performance of the cloud application is dependent upon the network access, speed and reliability

as well as the processing speed of the client device.Since cloud services are web-based, they

work on multiple platforms, including Linux, Macintosh, and Windows computers. Smart

phones, pads and tablet devices with Internet and World Wide Web access also provide cloud

services to telecommuting and mobile users.

3. Cloud Computing In Bangladesh

CISCO, GPIT and other organization is working to bring CLOUD in Bangladesh. According to

the officials of CISCO, they will need around two years to bring this product in Bangladesh.

They are currently working to improve the data centre.

American International University – Bangladesh, The pioneer of IT infrastructure in educational

institutions are already in a testing phase (2011). They will go in the full operation very soon.

Cost Analysis

Six major cloud Platforms

One of the latest trends is that cloud service providers are moving beyond specific verticals to

offer integrated platforms to support other developers to create new services. Salesforce,which

first introduced the concept, has gradually transformed itself from a CRM specialist into a full-

fledged application development and hosting platform. Its force.com currently has more than

70,000 applications developed by third parties, ranging from ERP and human resources to

compliance tracking and billing.

Through the App Engine, Google also offers a suite of tools that enables developers to develop

and deploy their Web applications onto Google’s infrastructure. Microsoft recen tly announced

the Windows Azure service platform that extends its rich desktop integrated development

environment (IDE) capabilities into the cloud environment

Traditional solutions versus cloud-based solutions

5. Cloud Computing Concern

Perhaps the biggest concerns about cloud computing are security and privacy. The idea of

handing over important data to another company worries some people. Corporate executives

might hesitate to take advantage of a cloud computing system because they can't keep their

company's information under lock and key.

The counterargument to this position is that the companies offering cloud computing services

live and die by their reputations. It benefits these companies to have reliable security measures in

place. Otherwise, the service would lose all its clients. It's in their interest to employ the most

advanced techniques to protect their clients' data.

Privacy is another matter. If a client can log in from any location to access data and applications,

it's possible the client's privacy could be compromised. Cloud computing companies will need to

find ways to protect client privacy. One way is to use authentication techniques such as user

names and passwords. Another is to employ an authorization format -- each user can access only

the data and applications relevant to his or her job.

Some questions regarding cloud computing are more philosophical. Does the user or company

subscribing to the cloud computing service own the data? Does the cloud computing system,

which provides the actual storage space, own it? Is it possible for a cloud computing company to

deny a client access to that client's data? Several companies, law firms and universities are

debating these and other questions about the nature of cloud computing.

How will cloud computing affect other industries? There's a growing concern in the IT industry

about how cloud computing could impact the business of computer maintenance and repair. If

companies switch to using streamlined computer systems, they'll have fewer IT needs. Some

industry experts believe that the need for IT jobs will migrate to the back end of the cloud

computing system.

6. Conclusion:

Cloud computing is heralded as the next big thing in enterprise IT. While corporate data

centers and on- premise software are not going away anytime soon, ―the clouds‖ will likely

have a growing impact on enterprise IT and business activities in many large organizations.

CIOs and other business leaders must look beyond the hype to see what opportunities and



8



challenges lie in the cloud —and how this approach can be used to further the organization’s

strategy to achieve high performance.
