- 2. CLOUD Also referred to as a network cloud. In telecommunications, a cloud refers to a public or semi-public space on transmission lines (such as T1 or T3) that exists between the end points of a transmission. Data that is transmitted across a WAN enters the network from one end point using a standard protocol suite such as Frame Relay and then enters the network cloud where it shares space with other data transmissions. The data emerges from the cloud -- where it may be encapsulated, translated and transported in myriad ways -- in the same format as when it entered the cloud. A network cloud exists because when data is transmitted across a packet-switched network in a packet, no two packets will necessarily follow the same physical path. The unpredictable area that the data enters before it is received is the cloud. 2
- 3. BASIC CLOUD CHARACTERISTICS The “no-need-to-know” in terms of the underlying details of infrastructure, applications interface with the infrastructure via the APIs. The “flexibility and elasticity” allows these systems to scale up and down at will utilising the resources of all kinds CPU, storage, server capacity, load balancing, and databases The “pay as much as used and needed” type of utility computing and the “always on!, anywhere and any place” type of network-based computing. 3
- 4. CLOUD STORAGE Cloud storage means "the storage of data online in the cloud," wherein a company's data is stored in and accessible from multiple distributed and connected resources that comprise a cloud. Cloud storage can provide the benefits of greater accessibility and reliability; rapid deployment; strong protection for data backup, archieval and disaster recovery purposes; and lower overall storage costs as a result of not having to purchase, manage and maintain expensive hardware. However, cloud storage does have the potential for security and compliance concerns. 4
- 5. CLOUD STORAGE Several large Web companies are now exploiting the fact that they have data storage capacity that can be hired out to others. allows data stored remotely to be temporarily cached on desktop computers, mobile phones or other Internet-linked devices. Amazon’s Elastic Compute Cloud (EC2) and Simple Storage Solution (S3) are well known examples Mechanical Turk 5
- 7. VIRTUALIZATION Virtual workspaces: An abstraction of an execution environment that can be made dynamically available to authorized clients by using well-defined protocols, Resource quota (e.g. CPU, memory share), Software configuration (e.g. O/S, provided services). Implement on Virtual Machines (VMs): Abstraction of a physical host machine, Hypervisor intercepts and emulates instructions from VMs, and allows management of VMs, VMWare, Xen, etc. Provide infrastructure API: Plug-ins to hardware/support structures App App App OS OS Hardware OS Hypervisor Virtualized Stack

- 9. CLOUD SERVICES Cloud services means services made available to users on demand via the Internet from a cloud computing provider's servers as opposed to being provided from a company's own on-premises servers. Cloud services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider. A cloud service can dynamically scale to meet the needs of its users, and because the service provider supplies the hardware and software necessary for the service, there’s no need for a company to provision or deploy its own resources or allocate IT staff to manage the service. Examples of cloud services include online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services and more. 9

CLOUD-SOURCING •Why is it becoming 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… 14
- 15. TYPES OF CLOUD 15
- 16. PRIVATE CLOUD Private cloud is the phrase used to describe a cloud computing platform that is implemented within the corporate firewall, under the control of the IT department. A private cloud is designed to offer the same features and benefits of public cloud systems, but removes a number of objections to the cloud computing model including control over enterprise and customer data, worries about security, and issues connected to regulatory compliance. Private Cloud Security A private cloud implementation aims to avoid many of the objections regarding cloud computing security. Because a private cloud setup is implemented safely within the corporate firewall, a private cloud provides more control over the company's data, and it ensures security, albeit with greater potential risk for data loss due to natural disaster. 16

- 18. PUBLIC CLOUD & HYBRID CLOUD Public clouds can also typically be deployed much faster and with more scalability and accessibility than on-premises infrastructure as a result of the public cloud provider’s expertise and existing infrastructure. Public cloud subscribers may pay pay-as-you-go fees or fixed monthly fees for the public cloud services they utilize. Hybrid Cloud: A combined form of private clouds and public clouds in which some critical data resides in the enterprise’s private cloud while other data is stored in and accessible from a public cloud. Hybrid clouds seek to deliver the advantages of scalability, reliability, rapid deployment and potential cost savings of public clouds with the security and increased control and management of private clouds. 18

- 20. CLOUD MANAGEMENT Cloud management means the software and technologies designed for operating and monitoring applications, data and services residing in the cloud. Cloud management tools help ensure a company's cloud computing-based resources are working optimally and properly interacting with users and other services. 20
- 21. THE REASON FOR CLOUD MANAGEMENT •Automation •Cloud-ready solutions •Control •Portability •A good cloud management platform delivers: •Ability to focus above the complexity & tedious work – to your core competency •Agility to IT and business •ROI almost immediately
- 22. CLOUD MANAGEMENT STRATEGIES 22 Cloud management strategies typically involve numerous tasks including performance monitoring (response times, latency, uptime, etc.), security and compliance auditing and management, and initiating and overseeing disaster recovery and contingency plans. With cloud computing growing more complex and a wide variety of private, hybrid, and public cloud-based systems and infrastructure already in use, a company’s collection of cloud management tools needs to be just as flexible and scalable as its cloud computing strategy.

- 32. OPPORTUNITIES AND CHALLENGES •The use 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”. 32
- 33. ADVANTAGES OF CLOUD COMPUTING •Instant software updates: –Another advantage to cloud computing is that you are no longer faced with choosing between obsolete software and high upgrade costs. –When the application is web-based, updates happen automatically •available the next time you log into the cloud. –When you access a web-based application, you get the latest version •without needing to pay for or download an upgrade. •Improved document format compatibility. –You do not have to worry about the documents you create on your machine being compatible with other users' applications or Oses •Unlimited storage capacity: –Cloud computing offers virtually limitless storage •Increased data reliability: –Unlike desktop computing, in which if a hard disk crashes and destroy all your valuable data, a computer crashing in the cloud should not affect the storage of your data. •Universal document access 33
- 34. DISADVANTAGES OF CLOUD COMPUTING 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. 34
- 35. THE FUTURE Many of the activities loosely grouped together under cloud computing have already been happening and centralised computing activity is not a new phenomena Grid Computing was the last research-led centralised approach However there are concerns that the mainstream adoption of cloud computing could cause many problems for users Many new open source systems appearing that you can install and run on your local cluster should be able to run a variety of applications on these systems 35
