Introduction

Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet.

Cloud computing describes a new supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.

From a business point of view, cloud computing is a method to address the scalability and availability concerns for large scale applications which involves lesser overhead.

[2]

What is Cloud Computing?

Cloud computing is Internet- ("cloud-") based development and use of computer technology ("computing").

A collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform).

Using the Internet for communication and transport provides hardware, software and networking services to clients

In addition, the platform provides on demand services, that are always on, anywhere, anytime and any place.

[3]

Pay for use and as needed, elasticscale up and down in capacity and functionalities

The hardware and software services are available togeneral public, enterprises, corporations and businesses markets

Characteristics of Cloud Computing

Self HealingHot backup of the application ready to take over without disruption.

Multi-tenancyAllows several customers to share the infrastructure allotted to them

without any of them being aware of the sharing. Linearly Scalable

Break down the workloads into pieces and service it across the infrastructure.

Service-orientedAllows re-use of the different services that are available and that are

being created. Virtualized Flexible

[5]

Cloud Architecture

Software as a Service (SaaS)

Platform as a Service (PaaS)

Infrastructure as a Service (IaaS)

[6]

Cloud Architecture

Centralized servers rather than from on-site servers

SaaS

Companies offering SaaS Salesforce.com,Google,NetSuite and Taleo

PaaSInterface for users to access applications

IaaS Google - Apps Engine, Amazon.com - EC2,Microsoft - Windows Live

Physical storage space and processing capabilities

Amazon.com - Cloud storage ,Google - Managed hosting, development environment,IBM

Companies offering PaaS

Companies offering PaaS

Types of Cloud Computing

Public cloud or external cloud

Private cloud and internal cloud

Hybrid cloud

Cloud computing enables companies and applications, which are system infrastructure dependent, to be infrastructure-less.

By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment!

Clients can: Put their data on the platform instead of on their own desktop

PCs and/or on their own servers. They can put their applications on the cloud and use the servers

within the cloud to do processing and data manipulations etc.

What is the purpose and benefits?

[10]

Advantages of Cloud Computing

Reduce spending on technology infrastructure

Globalize your workforce on the cheap

Reduce capital costs.

Improve accessibility.

Minimize licensing new software

Most have a pay structure that only calls for payment only when used

Easily scalable so companies can add or subtract storage based on their own needs

[11]

Conclusion

Cloud computing is a powerful new abstraction for large scale data processing systems which is scalable, reliable and available. In cloud computing, there are large self-managed server pools available which reduces the overhead and eliminates management headache.

Cloud computing is particularly valuable to small and medium businesses, where effective and affordable IT tools are critical to helping them become more productive without spending lots of money on in-house resources and technical equipment.
