Cloud Computing by Abhijeet Singh 2

What is a Cloud?

• Cloud refers to a network over the internet. It derives its name from the time clouds were used to represent telephone networks and the internet in computer networks later on.

• Clouds often appear as single points of access for consumers' computing needs. This causes centralization of data and gives mobility and versatility to the users of cloud services.


Why use the cloud?

• Using cloud computing has multiple benefits such as automated backups, multiple and simultaneous data access and unmatched data portability all combined over a steep reduction in server and storage costs.


What is Cloud Computing?

• Cloud computing is network based computing where shared resources software and information are shared among multiple users.

• Cloud computing allows a user to consume the resources without investing in the basic infrastructure such as software licensing, Server procuring and maintenance costs.

• It is like Gmail, use when you want and where you want.


Understanding Cloud Computing

• Client consists of computer hardware or software.

• Application /Platform/Infrastructure (As the case may be)

• Server refer to the hardware or software designed specifically for delivery in the cloud.


Why Cloud computing?

• There is only one versatile application provided by the provider which in turn saves the cost for both the provider and the consumer.

• The users pays only for the services they use(Such as

Electricity) or on a timely basis(Such as club membership). This gives cloud computing an advantages as the user pays for only for what he uses and hence allows to save huge costs for the consumer.


What services are available in the market?

• Cloud Operating Systems • Online Storage• Online office suites• Cloud hosting• Online sales management over the cloud• Online CRM• Cloud collaboration• Online app development• Email Services• Instant messaging services


Applications in business

• Small and Medium Enterprises(SMEs) are getting increasingly associated with Cloud Computing as they cannot justify or afford the large capital expenditure of IT.

• SMEs in emerging market can be benefited by established infrastructure of provider and inexpensive models of management.


Kinds of Cloud Computing

• Software As a Service.(SaaS)• Platform As a service.(PaaS)• Infrastructure As a service (IaaS)

• Software as a Service(SaaS) is providing all the features of a sophisticated software, but through a browser , not a locally installed application. SaaS eliminates worries about app servers, storage, application development and related, common concerns of IT. The best examples are Salesforce.com, Google’s Docs


Kinds of Cloud Computing

• Platform As a service(PaaS) is about providing virtualized servers and allowing users to run and develop applications on them without having to worry about maintaining the operating system and processing capabilities. Examples Microsoft Azure & Salesforce’s Force.com

• Infrastructure As a service (IaaS) aims to replace the need of a data centre. It provides cluster of networks, storages, and servers . Example Amazon’s Elastic Compute Cloud [EC2].


How is service provided and payment made?

• Services are provided by the extensive use of internet and networking. The user subscribes only to the services which he needs. Whenever the user needs to change the quantum of services he can request the service provider to provoke or revoke a particular service.

• Payment is usually made on a pay as you use basis i.e. either on utility basis or on a timely basis. That is the user need not to pay for the processing capability which he doesn’t need.


Who are the providers?

• Providers of Cloud Computing servicesIaaS•Windows live-

Skydrive•Amazon EC2•Chatter

PaaS•Microsoft Azure•Salesforce’s Force.com•eyeOS’s web app development

SaaS•Google Docs and

Gmail•VoIP services from

Skype•IM service from

AOL


Database Storage Service

• Cloud storage is a model of networked online storage where data is stored in virtualized pools of storage which are generally hosted by third parties.


Properties of Cloud Storage

• Cloud storage is:• made up of many distributed resources, but still

acts as one• highly fault tolerant through redundancy and

distribution of data• highly durable through the creation of versioned

copies• typically eventually consistent with regard to data

replicas

Features in Cloud Computing

• Cost Saving Both for the service provider and consumer deploying the cloud is a profitable issue.

• Security Because of centralization providers are able to use security features that many users are not able to afford.

• Metering means the usage is measureable on a per client or per user basis.

• Multi tenancy enables sharing of resources and costs across a large pool of users. Peak-load capacity increases

• Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using (e.g., PC, mobile)


Issues in Cloud Computing

• Privacy privacy over the cloud may be compromised as the data crucial to the organization is stored outside the organization

• Compliance users may have to adopt community or hybrid deployment

modes which are typically more expensive and may offer restricted benefits.• Adaptability as there is a single app provided by the provider it may

not be perfectly suitable for the consumer’s need.

• Connectivity poor connectivity to the provider may lead to inefficiency on the end of consumer.


Cloud Implementation

• The cloud as a new and developing technology has unlimited potential.

• The development of cloud OS such as Azure and Chromium have heralded a new era of networking and multitasking.

• Implementing cloud in the organization saves precious profits.


Cloud in education

• Networked institutions such as universities can create vast repositiries of knowledge that can be accessed over the cloud.

• OPAC has been implemented in vaious universities around the globe including DAVV.


Cost saving by Cloud

• Every year services such as Smartcloud by IBM save thousands of rupees.

• Cloud delivers secure and scalable hosted IT infrastructure with on-demand access to virtual server and storage resources. Well suited for development and test activities, as well as other dynamic workloads.
