What isCloud Computing?

DEFINITION

Cloud computing is an emerging computing technology that uses the internet and central remote servers to maintain data and applications´.

INTRODUCTION

The underlying concept of cloud computing dates back to 1960, when John McCarthy opined that "computation may someday be organized as a public utility"; indeed it shares characteristics with service bureaus that date back to the 1960s.

The actual term "cloud" borrows from telephony in that telecommunications companies, who until the 1990s primarily offered dedicated point-to-point data circuits, began offering ³VIRTUALPRIVATE NETWORK (VPN)´ services with comparable quality of service but at a much lower cost.

The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider from that of the user. Cloud computing extends this boundary to cover servers as well as the network infrastructure.

Cost is claimed to be greatly reduced and capital expenditure is converted to operational expenditure. Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using

WHY CLOUD COMPUTING ?

• Pay per use• Instant Scalability• Security• Central Authentication• APIs• Global Accessibility• Easy to use • Rapid Deployment• Low Cost• Flexibility

WHY CLOUD COMPUTING ?

Helps to use applications without installations.

Access the personal files at any computer with internet access.

This technology allows much more efficient computation by centralizing storage, memory , processing and band width

USE

SURVEY

Based on a study conducted in June 2010 by version one, 41% of IT senior professionals doesn’t have sound knowledge on cloud computing.

In September 2011 , Aberdeen Group found that 18%reduction in there IT budget and a 16% reduction in datacenter power costs.

LAYERS

A cloud client consists of computer Hardware and/or computer software that relies on cloud computing for application delivery

SERVER

The servers layer consists of computer hardware and/or computer software products that are specifically designed for the delivery of cloud services, including multi-core processors, cloud-specific operating systems and combined offerings

DEPLOYMENT MODELS

COMMUNITY CLOUD:

A community cloud may be established where several organizations have similar requirements and seek to share infrastructure so as to realize some of the Benefits of cloud computing with the costs spread over fewer users than a public cloud , this option is more expensive but may offer a higher level of privacy .

Eg : Google’s Gov Cloud

HYBRID CLOUD

A hybrid cloud environment consists of multiple internal and external providers “ will be typical for most enterprises “ . By integerating multiple cloud , users may be able to ease the transition to public cloud services

PRIVATE CLOUD

Private cloud and Internal cloud are expressions that some vendors have recently used to describe offering that emulate cloud computing on private networks. These products claim “ to deliver some benefits of the cloud computing without pitfall ”, capitalizing on data security, corporate governance and reliability concerns. They have been criticized on the basis that

“ users still buy , build and manage them” and as such do not benefit from lower up-front capital costs and less hand on management.

HIGH LEVEL MARKET ORIENTED CLOUD ARCHITECTURE

A MODERN APPLICATION PLATFORM CAN BE VIEWED AS HAVING THREE PARTS

TAXONOMY FOR CLOUD COMPUTING

SERVICE PROVIDER

Application Programming Interfaces (APIs)

Levels of APIs Level 1 – The Wire: At this level, the developer writes directly to the wire

format of the request. Level 2 – Language-Specific Toolkits: Developers at this level use a

language- specific toolkit to work with requests. Level 3 – Service-Specific Toolkits: The developer uses a higher-level

toolkit to work with a particular service. Level 4 – Service-Neutral Toolkits: This is the highest level of API. A

developer working at this level uses a common interface to multiple cloud computing

Level 5 – Internal Interfaces: Programming interfaces for the internalinterfaces between the different parts of a cloud infrastructure.

“We are at the beginning of the age of planetary computing. Billions of people will be wirelessly interconnected, and the only way to achieve that kind of massive scale usage is by massive scale, brutally efficient cloud-based infrastructure.”
