- 2. What is CloudComputing? Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet, ◦ basically a step on from Utility Computing ◦ a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform). ◦ Using the Internet for communication and transport provides hardware, software and networking services to clients These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very simple graphical interface or API (Applications Programming Interface).
- 3. What is CloudComputing? In addition, the platform provides on demand services, that are always on, anywhere, anytime and any place. Pay for use and as needed, elastic ◦scale up and down in capacity and functionalities The hardware and software services are available to ◦general public, enterprises, corporations and businesses markets
- 4. What is CloudComputing? Cloud computing is an umbrella term used to refer to Internet based development and services. A number of characteristics define cloud data, applications services and infrastructure: ◦ Remotely hosted: Services or data are hosted on remote infrastructure. ◦ Ubiquitous: Services or data are available from anywhere. ◦ Commodified: The result is a utility computing model similar to traditional that of traditional utilities, like gas and electricity - you pay for what you would want!
- 5. What is CloudComputing? Many companies are delivering services from the cloud. Some notable examples include the following: • Google — Has a private cloud that it uses for delivering Google Docs and many other services to its users, including email access, document applications, text translations, maps, web analytics, and much more. • Microsoft — Has Microsoft® Office 365® online service that allows for content and business intelligence tools to be moved into the cloud, and Microsoft currently makes its office applications available in a cloud. • Salesforce.com — Runs its application set for its customers in a cloud, and its Force.com and Vmforce.com products provide developers with platforms to build customized cloud services.
- 6. Basic Concepts There arecertain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models for cloud computing: 1. Deployment Models 2. Service Models
- 7. Deployment Models Deployment modelsdefine the type of access to the cloud, i.e., how the cloud is located? Cloud can have any of the four types of access: Public, Private, Hybrid and Community.
- 8. Deployment Models PUBLIC CLOUD: The Public Cloud allows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness, e.g., e-mail. PRIVATE CLOUD : The Private Cloud allows systems and services to be accessible within an organization. It offers increased security because of its private nature. COMMUNITY CLOUD : The Community Cloud allows systems and services to be accessible by group of organizations. HYBRID CLOUD : The Hybrid Cloud is mixture of public and private cloud. However, the critical activities are performed using private cloud while the non- critical activities are performed using public cloud.
- 9. Service Models Service Modelsare the reference models on which the Cloud Computing is based. These can be categorized into three basic service models as listed below: 1. Infrastructure as a Service (IaaS) 2. Platform as a Service (PaaS) 3. Software as a Service (SaaS)
- 11. Infrastructure as aService (IaaS) IaaS is the delivery of technology infrastructure as an on demand scalable service. IaaS provides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc. •Usually billed based on usage •Usually multi tenant virtualized environment •Can be coupled with Managed Services for OS and application support

- 13. Platform as aService (PaaS) PaaS provides the runtime environment for applications, development & deployment tools, etc. PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet. Typically applications must be developed with a particular platform in mind. •Multi tenant environments •Highly scalable multi tier architecture

- 15. Software as aService (SaaS) SaaS model allows to use software applications as a service to end users. SaaS is a software delivery methodology that provides licensed multi-tenant access to software and its functions remotely as a Web- based service. • Usually billed based on usage • Usually multi tenant environment • Highly scalable architecture

- 17. What is thepurpose 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. Cloud-Sourcing Why is itbecoming a Big Deal: ◦ Using high-scale/low-cost providers, ◦ Any time/place access via web browser, ◦ Rapid scalability; incremental cost and load sharing, ◦ Can forget need to focus on local IT. Concerns: ◦ Performance, reliability, and SLAs, ◦ Control of data, and service parameters, ◦ Application features and choices, ◦ Interaction between Cloud providers, ◦ No standard API – mix of SOAP and REST! ◦ Privacy, security, compliance, trust…
- 19. Opportunities and Challenges Theuse of the cloud provides a number of opportunities: ◦ It enables services to be used without any understanding of their infrastructure. ◦ Cloud computing works using economies of scale: ◦ It potentially lowers the outlay expense for start up companies, as they would no longer need to buy their own software or servers. ◦ Cost would be by on-demand pricing. ◦ Vendors and Service providers claim costs by establishing an ongoing revenue stream. ◦ Data and services are stored remotely but accessible from “anywhere”.
- 20. Opportunities and Challenges Inparallel there has been backlash against cloud computing: ◦ Use of cloud computing means dependence on others and that could possibly limit flexibility and innovation: ◦ The others are likely become the bigger Internet companies like Google and IBM, who may monopolise the market. ◦ Some argue that this use of supercomputers is a return to the time of mainframe computing that the PC was a reaction against. ◦ Security could prove to be a big issue: ◦ It is still unclear how safe out-sourced data is and when using these services ownership of data is not always clear.
- 21. Opportunities and Challenges ◦There are also issues relating to policy and access: ◦ If your data is stored abroad whose policy do you adhere to? ◦ What happens if the remote server goes down? ◦ How will you then access files? ◦ There have been cases of users being locked out of accounts and losing access to data.
- 22. Benefits • Cost Savings— Companies can reduce their capital expenditures and use operational expenditures for increasing their computing capabilities. This is a lower barrier to entry and also requires fewer in-house IT resources to provide system support. • Scalability/Flexibility — Companies can start with a small deployment and grow to a large deployment fairly rapidly, and then scale back if necessary. Also, the flexibility of cloud computing allows companies to use extra resources at peak times, enabling them to satisfy consumer demands. • Reliability — Services using multiple redundant sites can support business continuity and disaster recovery. • Maintenance — Cloud service providers do the system maintenance, and access is through APIs that do not require application installations onto PCs, thus further reducing maintenance requirements. • Mobile Accessible — Mobile workers have increased productivity due to systems accessible in an infrastructure available from anywhere.
- 23. Disadvantages of CloudComputing Requires a constant Internet connection: ◦ Cloud computing is impossible if you cannot connect to the Internet. ◦ Since you use the Internet to connect to both your applications and documents, if you do not have an Internet connection you cannot access anything, even your own documents. ◦ A dead Internet connection means no work and in areas where Internet connections are few or inherently unreliable, this could be a deal-breaker.
- 24. Disadvantages of CloudComputing Stored data might not be secure: ◦ With cloud computing, all your data is stored on the cloud. ◦ The questions is How secure is the cloud? ◦ Can unauthorized users gain access to your confidential data? Stored data can be lost: ◦ Theoretically, data stored in the cloud is safe, replicated across multiple machines. ◦ But on the off chance that your data goes missing, you have no physical or local backup. ◦ Put simply, relying on the cloud puts you at risk if the cloud lets you down.
