What is the cloud Cloud computing

◦ A type of computing that relies on sharing computer resources rather than having local servers or personal devices-http://www.webopedia.com/TERM/C/cloud_computing.html

◦ The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer - Google

◦ The elastic leasing of pooled computer resources over the internet – MIS book

Evolution of The Cloud Grid Computing

◦ Solving large problems with parallel computing

Utility Computing◦ Offering computing

resources as a metered service

SaaS◦ Network based

subscriptions to applications

Cloud Computing◦ Anytime, anywhere access

to IT resources delivered dynamically as a service

How Cloud Computing Works

How Cloud Computing Works

Typically each application will have its own dedicated server

There are multiple digital storage devices that are located all over the globe to keep data safe and secure. If one server goes down the data is replicated on multiple other servers so the data is always available to the end user

Characteristics of CloudA number of characterises can be used to define the nature of the solution and services offered through cloud computing:

Benefits of the cloud‣ Cost Effectiveness

‣ Unlimited Data storage and security

‣ Backup and Disaster Recovery

‣ Ease of access and availability

‣ Connect Seamless Connectivity to all their data,

data of their partners, customers
