Introduction

When you store your documents online instead of on your home computer, or use webmail or a social networking site, you are using a “cloud computing” service.

If you are an organization, and you want to use, for example, an online invoicing service instead of updating the in-house one you have been using for many years, that online invoicing service is a “cloud computing” service.

"Cloud computing is a buzzword..." "The concept, quite simply, is that vast computing resources will reside somewhere out there in the ether (rather than in your computer room) and we'll connect to them and use them as needed." • - Jonathan Weber (The Times Online)

Myths & Facts Myths Cloud computing will eliminate the need for IT personnel. Cloud computing will eliminate IT expense.

Facts Cloud technology is real. This technology should not be ignored. This presentation will assist you in understanding “The Cloud”.

What is Cloud Computing? 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.

Cloud computing is comparable to grid computing, a type of

computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine.

Why Cloud Computing On demand self service Customer can request and manage their own computing resources. Broad network access Allows services to be offered over the internet or private networks. Resource pooling customers draw from a pool of computing resources,usually in remote data centres. Rapid elasticity Services can be scaled larger or smaller. Measured service use of service is measured and customers are billed accordingly.

Cloud Architecture

Cloud Service Models

SaaS

• Software as a service

• Service Applications, typically available via the browser

• Pre-made application

• Access to both resources and application.

PaaS

• Platform as a service

• Hosted application environment for building and deploying cloud applications

• Access to components require to develop and operate application.

IaaS

• Infrastructure as a service

• Utility computing data center providing on demand server resources

• Completely outsources the storage and resources, such as hardware and software.

Types of Cloud Storage Public Cloud Services are delivered to the client via the Internet. Services can be shared by various organizations. Access to the cloud space.

Example: Amazon, Google, Microsoft, Sales force

Private Cloud Services are managed and provided within the organization. There are less restriction on network bandwidth. Fewer security exposures and other legal requirements. More expensive and more secure. Example: HP data center, IBM, Sun, Oracle, 3tera

Hybrid Cloud Combination of services provided from public and private Clouds. Hosting critical applications on private clouds. relatively less security concerns on public cloud.

Example: ERP in Private cloud andSales & Email on public

Pros and Cons Pros Reduce E-Waste Reduce spending on technology Low up-front cost Improve accessibility and flexibility Less personal training is needed Monitor project more effectively Rapid deployment and customization Increased data reliability Allow for better audit trails

Cons Security & Privacy Is it safe? For Whom and at what level? Regulatory compliance: HIPPA, SOX etc Interoperability & Vendor Lock-In Lack of control Standardization Bandwidth could bust your budget Legal issues

ConclusionCloud Computing holds some strong promises– Highly Available– Dynamically allocate resources– Pay only for resources that you use

If you are considering using the cloud,

Be certain that you identify what information you will be putting out in the cloud, who will have access to that information, and what you will need to make sure it is protected.

know your options in terms of what type of cloud will be best for your needs, what type of provider will be most useful to you, and what the reputation and responsibilities of the providers you are

considering .
