You are probably using cloud computing right now, even if you don’t realise it. If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games or store pictures and other files, it is likely that cloud computing is making it all possible behind the scenes.. Here are a few of the things you can do with the cloud:

·        Create new apps and services

·        Host websites and blogs

·        Stream audio and video

·        Deliver software on demand.

What is Cloud?

The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is present at remote location. Cloud can provide services over public and private networks, i.e., WAN, LAN or VPN.

Applications such as e-mail, web conferencing, customer relationship management (CRM) execute on cloud.

What is Cloud Computing?

Cloud Computing refers to manipulating, configuring, and accessing the hardware and software resources remotely. It offers online data storage, infrastructure, and application.

Cloud computing offers platform independency, as the software is not required to be installed locally on the PC. Hence, the Cloud Computing is making our business applications mobile and collaborative.

Models for cloud computing:

• Deployment Models

• Service Models

Deployment Models

Deployment models define the type of access to the cloud, i.e., how the cloud is located? Cloud can have any of the four types of access:

 

PUBLIC CLOUD

   The public cloud allows systems and services to be easily accessible to the      general public. Public cloud may be less secure because of its openness.

PRIVATE CLOUD

   The private cloud allows systems and services to be accessible within an         organization. It is more secured because of its private nature.

COMMUNITY CLOUD

   The community cloud allows systems and services to be accessible by a          group of organizations.

HYBRID CLOUD

  The hybrid cloud is a mixture of public and private cloud, in which the            critical  activities are performed using private cloud while the non-critical          activities are performed using public cloud.

Service Models

Cloud computing is based on service models. These are categorized into three basic service models which are -

INFRASTRUCTURE-AS-A-SERVICE (IAAS)

IaaS provides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc.

PLATFORM-AS-A-SERVICE (PAAS)

PaaS provides the runtime environment for applications, development and deployment tools, etc.

SOFTWARE-AS-A-SERVICE (SAAS)

SaaS model allows to use software applications as a service to end-users.

Career Aspects

 It has also been estimated that India will need about 3 lakh cloud computing professionals in the next four years.

So if you choose to make a career in Cloud Computing, you can look forward to an annual salary package of Rs 12 to 19 lakh at the entry-level. A middle-level executive usually earns around Rs 20 lakh per annum while those who have 10 to 15 years of experience in the field can earn a package of Rs 30 lakh or more.

SCOPE OF CLOUD COMPUTING IN FUTURE

According to an IBM statistic about 85% of new applications are being developed around Cloud Computing.

Studies by NASDAQ indicate that investments in cloud technology is likely to expand over US$ 40 million by the year 2018.
