Cloud computing is a term which has Been recently used quite often, but Very few of us know what it is all about. However, in reality, Cloud computing is a Simple technology that has been around for a while and almost all of us have been Using it without even realizing. Cloud Computing, “entails running of computer Network applications and database applications remotely using a simple user Interface or application format”.

The IT Encyclopedia defines cloud computing as “A general term for anything

That involves delivering hosted services over the internet. A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or Hour; it is elastic – a user can have as Much or as little of a service as they want at any given time; and the service is fully Managed by the provider. In fact, cloud Computing is “computation, software, Data access, and storage services that do

Not require end-user knowledge of the Physical location and the configuration of

The system that delivers the services. ”


Thus, cloud computing is a computational Paradigm based on consume of

Resources, applications, hardware or Computation, offered by internet and consumed

Under demand. If the language still sounds strange to you, going back to the basics will enlighten about what Cloud computing is all about. Back to the olden days of networking, When Google, Yahoo was still an Idea, companies ran e-mail as an application whose data was stored in-house, that eventually grew in number making it Very difficult to store and secure it at the same time. During the 20th century, Google revolutionized the use of email. Google would have made it a commercial Bid to customers, but these companies Choose to open their servers to store Information free of charge. However, for this, they came up with several new ideas to store and transmit information by use of several applications like Gmail, Yahoo Mail and many others. This is all about the concept of Cloud Computing – using other people’s servers to run applications for our own organization remotely. Nowadays the use of cloud computing is expanding exponentially. During The 21st century, Cloud Computing has evolved all the more. It is now used to decide the future of the business of many big organizations using several analyzing techniques. Whenever we use a cloud, our computer communicates

With a network of servers. As a Result, we can be benefitted several



  1. Value for money: Cloud computing Facilitates the concept of pay per use Computing resources on a short term Basis and the ability to release these Resources when they are no longer needed.


  1. Increased scalability: by providing Pool of IT resources, along with tools and technologies to leverage them

Collectively, cloud can instantly and dynamically allocate IT resources to the consumers thus fulfilling the supply

On demand chain.

  1. Increased availability and reliability: This facility helps in booming the Business process. IT resources with increased availability for longer periods of time are available on the cloud that guarantees high levels of availability. There are several cloud delivery models that is designed based on pre-packaged Combination of IT resources offered by a Cloud provider.

Three commonly used

Cloud delivery models are as follows:


(I) Software as a Service (Seas): These services are applications over Internet. User can run these applications using web-browser. An example of this kind of services may be Google Docs.


(ii) Platform as a Service (PaaS): These kinds of services are focused

On the deployment of applications or Services online letting to the developer Manage the hardware or software Necessary, including solutions. This Service includes all the life-cycle of the deployment of applications/service Such as design, implementation, Testing, deployment, integrity with Databases etchant example of these Services are Google App engine.

(iii) Infrastructure as a Service (IaaS): This service offers a computer architecture. All the servers, connections, software and other resources are offered by the providers. The users see it like an entire infrastructure Hosted in the same organization.


Let us throw some light on the most commonly

Used terms in Cloud computing:



  1. Cloud provider: The organization that provides cloud-based IT Resources is the cloud provider. They Own the IT resources that are made Available for cloud consumers.


  1. Cloud consumer: Any organization or human that has a formal contract or arrangement with a cloud provider

To use IT resources by the cloud Provider


  1. Cloud service owner: The person or organization that legally owns a Cloud service is called a cloud service Owner. It can be a cloud consumer or a cloud provider who owns the cloud service.


  1. Cloud Resource Administrator: A Cloud resource administrator is a person or organization responsible for

Administering a cloud based IT Resource.

There are three types of clouds:


(I) Public Cloud: The public cloud or the external cloud, is the traditional Way, where services are provided by

A third party via internet, and they are Visible to everybody.

(ii) Private Cloud: This cloud consists on the hosting of private applications, Storage or computation in the same

Company emulating a cloud in internet but only for private use (private Networks).


(iii) Hybrid cloud: It is a combination of Public and private cloud. An organization can have a part of their services

In its own infrastructure but also in Public cloud. It is a very good option When we want to have our data or

Application in local and don’t want to Invest too much in infrastructure.

How hot is a career in Cloud?  Computing?

It is a strong message for the 2.8 million Strong workforces that make up the countries

Information Technology (IT) industry.

Recently, there have been an increasing Number of demands in the Cloud sector, which resulted in the high demand of?

Installation and maintenance engineers. Although Cloud computing has its roots in the early 21st Century, India has seen its Boom in the Industry sector during the Last three years where computing is delivered

As service over the internet rather Than as a product installed inside a company’s Premises. By a study, it has been

Found by analysts that India will encourage Another 2 million new jobs in Cloud Sector by 2016. It is now essential for the IT engineers to adapt themselves to the Changing environment of Cloud market. A Study by EMC and Zinnia Management Consulting estimated the total cloud market In India at $400 million which is expected to touch $4.5 billion by end of 2015. It expects the private cloud market, where the infrastructure is operated for

Specific companies, to create another 100,000 IT jobs by 2015 from 10,000.With the advent of Cloud computing market

Several new positions such as Enterprise cloud architect has emerged, who understands both IT NFRASTRUCTURE?

And applications; and who can design and manage application frameworks. Besides the technical job scenario, several Marketing jobs for marketing and selling of cloud-based solutions are also on Demand nowadays.

Institutions and Universities that offer Cloud computing courses

Being a recent trend, a handful of institutions and universities currently offer this course as a career to the students in future. However, this trend is expected to increase with all universities setting up several cloud computing courses in near future. Qualifications for undertaking such a course require mainly students from Science background in 10+2 with Math’s, Physics and Chemistry as required subjects. A mere background of

IT sector during that time will prove to be an added advantage while pursuing this course. No such hardcore background of IT is necessary to start a course in Cloud computing as this course provides all the core basic knowledge in Computer science in addition to Cloud computing knowledge. Several universities in the Northeast will adopt cloud and mobile technology in their graduate levels which will give an edge to students from the

Region looking to make a career in the burgeoning field. University of Technology and Management (UTM),

Shillong has already taken its leap in providing the students a career in B.Tech in Computer science with specialization in Cloud Computing and Virtualization. UTM is a sister university of University of

Petroleum and Energy Studies, Dehradun (UPES) which has already taken this step long back producing Industry ready students for the IT and management market. Several other universities such as Galgotias University (Noida), DUCAT (Noida), Apeejay Stya University (Gurgaon), NIT Tirchi, Indian Institute of Hardware Technology (IIHT),

Poornima University, Jaipur (BCA-IT-IMS and Cloud Technology) etc. are also providing the Cloud Computing as a
