Slide 2: 

Cloud Computing 2 Cloud computing is a general term for anything that involves delivering hosted services over the Internet. The name cloud computing was inspired by the ‘cloud’ symbol that's often Used to represent the Internet in flowcharts and diagrams. What is CLOUD COMPUTING?

Slide 3: 

Cloud Computing 3 Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. (An electrical grid is an interconnected network for delivering electricity from suppliers to consumers.) What is CLOUD COMPUTING?

Slide 4: 

Cloud Computing 4 These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS): IaaS like Amazon Web Services provides virtual server instances with unique IP addresses. It blocks of storage on demand. Customers use the provider's application program interface (API) to start, stop, access and configure their virtual servers and storage.

Slide 5: 

Cloud Computing 5 Platform-as-a-Service (PaaS): PaaS in the cloud is defined as a set of software and product development tools hosted on the provider's infrastructure. Developers create applications on the provider's platform over the Internet. PaaS providers may use APIs, website portals or gateway software installed on the customer's computer. Exp: Force.com and GoogleApps.

Slide 6: 

Cloud Computing 6 In the SaaS cloud model, the vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. SaaS is a very broad market. Services can be anything from Web-based email to inventory control and database processing. Because the service provider hosts both the application and the data, the end user is free to use the service from anywhere. Software-as-a-service:

Slide 7: 

Cloud Computing 7 A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour. It is elastic: a user can have as much or as little of a service as they want at any given time. The service is fully managed by the provider.

Slide 8: 

Cloud Computing 8 Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources. The term "cloud" is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network, and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Most cloud computing infrastructures consist of services delivered through common centers and built on servers.

Slide 9: 

Cloud Computing 9 The major cloud service providers include Microsoft Salesforce Skytap HP IBM Amazon Google.

Slide 10: 

Cloud Computing 10 History: 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 Virtual Private Network(VPN) services with comparable quality of service but at a much lower cost.

Slide 11: 

Cloud Computing 11 History(cont…) Amazon played a key role in the development of cloud computing by modernizing their data centers after the dot-com bubble, which, like most computer networks. In 2007, Google, IBM and a number of universities embarked on a large scale cloud computing research project.

Slide 12: 

Cloud Computing 12 In March 2010, Microsoft's CEO, Steve Ballmer, made his strongest statement of betting the company's future in the cloud by proclaiming "For the cloud, we're all in" and further stating "About 75 percent of our folks are doing entirely cloud based or entirely cloud inspired, a year from now that will be 90 percent." History(cont…)

Cloud Computing 13 Layers Of Cloud Computing

Slide 14: 

Cloud Computing 14 Layers: A cloud client consists of computer hardware and computer software that relies on cloud computing for application delivery, or that is specifically designed for delivery of cloud services and that, in either case, is essentially useless without it. Examples include some computers,phones and other devices, operating systems and browsers. Client:

Slide 15: 

Cloud Computing 15 Application: Cloud application services or sofware as a service deliver software as a service over the internet, eliminating the need to install and run the application on the customer's own computers and simplifying maintenance and support.

Slide 16: 

Cloud Computing 16 Cloud platform services deliver a computing platform and/or solution stack as a service, often consuming cloud infrastructure and sustaining cloud applications. It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers. Platform

Slide 17: 

Cloud Computing 17 Infrastructure Cloud infrastructure services delivers computer infrastructure,typically a platform virtualization environment as a service. Rather than purchasing servers, software, data center space or network equipment, clients instead buy those resources as a fully outsourced service.

Slide 18: 

Cloud Computing 18 The servers layer consists of computer hardware and computer software products that are specifically designed for the delivery of cloud services, including multi-core processors, cloud-specific operating systems and combined offerings. Server:

Cloud Computing 19 Deployment models

Slide 20: 

Cloud Computing 20 Public Cloud Hybrid Cloud Private cloud Deployment models

Slide 21: 

Cloud Computing 21 Public cloud Public cloud or external cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications or web services, from an off-site third-party provider who and bills on a fine-grained utility computing basis.

Slide 22: 

Cloud Computing 22 A hybrid cloud environment consisting of multiple internal and /or external providers will be typical for most enterprises. By integrating multiple cloud services users may be able to ease the transition to public cloud services while avoiding issues such as PCI compliance. Hybrid cloud

Slide 23: 

Cloud Computing 23 Another perspective on deploying a web application in the cloud is using Hybrid Web Hosting, where the hosting infrastructure is a mix between Cloud Hosting for the web server, and Managed dedicated server for the database server. Hybrid cloud(cont…)

Slide 24: 

Cloud Computing 24 Private cloud This idea was based upon direct comparison with other industries and the extensive use of hybrid supply models to balance. Private cloud and internal cloud have been described as neologisms, however the concepts themselves pre-date the term cloud by 40 years. Even within modern utility industries, hybrid models still exist despite the formation of reasonably well functioning markets and the ability to combine multiple providers.

Slide 25: 

Cloud Computing 25 A cloud can be private or public: A public cloud sells services to anyone on the Internet. A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people.

Slide 26: 

Cloud Computing 26 When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services.

Slide 27: 

Cloud Computing 27 Cloud Storage Cloud Storage is a model of networked Computer data storage where data is stored on multiple virtual servers, generally hosted by third parties, rather than being hosted on dedicated servers. Hosting companies operate large data centers; and people who require their data to be hosted buy or lease storage capacity from them and use it for their storage needs.

Slide 28: 

Cloud Computing 28 The data center operators, in the background, virtualize the resources according to the requirements of the customer and expose them as virtual servers, which the customers can themselves manage. Physically, the resource may span across multiple servers. Cloud Storage(cont…)

Slide 29: 

Cloud Computing 29 The Intercloud The Intercloud is based on interconnected global "cloud of clouds" and an extension of the Internet "network of networks“ The term was first used in the context of cloud computing in 2007. This Intercloud will have the dimensions of one machine comprising all servers and attendant cloudbooks on the planet.". It became popular in 2009 and has also been used to describe the datacenter of the future.

Slide 30: 

Cloud Computing 30 The Intercloud scenario is based on the key concept that each single cloud does not have infinite physical resources. If a cloud saturates the computational and storage resources of its virtualization infrastructure, it could not be able to satisfy further requests for service allocations sent from its clients. The Intercloud scenario aims to address such situation, and in theory, each cloud can use the computational and storage resources of the virtualization infrastructures of other clouds. The Intercloud
