Cloud Computing

• Just make you familiar with Cloud Computing and its Services

• Explore Cloud Computing and how it can be used for providing library services2

Our effort is to:

What is Cloud Computing?Distributed computing on internet Or delivery of computing service over the internet.Eg: Yahoo!, GMail, Hotmail-

Instead of running an e-mail program on your computer, you log in to a Web e-mail account remotely. The software and storage for your account doesn't exist on your computer -- it's on the service's computer cloud.

HistoryConcept evolved in 1950(IBM) called RJE

(Remote Job Entry Process).In 2006 Amazon provided First public

cloud AWS(Amazon Web Service).

Cloud ComponentsIt has three components 1.) Client computers2.) Distributed Servers3.) Datacenters

ClientsClients are the device that the end user interact with cloud. three types of clients:

1.) Mobile2.) Thick3.) Thin (Most Popular)

DatacenterIt is collection of servers where application is placed and is accessed via internet.

Distributed serversOften servers are in geographically different places, but server acts as if they are working next to each other.

Central ServerIt Administers the system such as

monitoring traffic, client demands to ensure everything runs smoothly.

It uses a special type of software called Middleware.

Middleware allow computer to communicate each other.

Service ModelsSaaS(Software as a service):

Required software, Operating system & network is provided.

PaaS(Platform as service): Operating system and network is provided.

IaaS(Infrastructure as a service): just Network is provided.

Deployment of Cloud Service

Public CloudPrivate CloudCommunity CloudHybrid Cloud(Combined Cloud)

Why cloud service is popular? Reduce the complexity of networks. Do not have to buy software licenses. Customization. Cloud providers that have specialized in a

particular area (such as e-mail) can bring advanced services that a single company might not be able to afford or develop.

scalability, reliability, and efficiency. Info. at cloud are not easily lost.

ApplicationSocial Networking sites.E-mail sites.Search Engines.Many more services OVER THE

INTERNET.

Challenges

Alignment with the needs of the business / user / non-computer specialists / community and society

Need to address the scalability issue: large scale data, high performance computing, automation, response time, rapid prototyping, and rapid time to production

Need to effectively address (i) ever shortening cycle of obsolescence, (ii) heterogeneity and (iii) rapid changes in requirements

Transform data from diverse sources into intelligence and deliver intelligence to right people/user/systems

What about providing all this in a cost-effective manner?

What is the purpose and benefits?

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. 18
