Cloud computing allows users to access computing resources like servers, storage, databases, networking, software, analytics and more over the internet. It provides scalability, reliability and cost savings. There are different cloud service models like Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Users can choose between public, private or hybrid cloud deployment models based on their needs.

- 3. What is Cloud Computing? Cloud computing is internet-based computing in which large groups of remote servers are networked to allow the centralized data storage, and online access to computer services or resources. Clouds can be classified as public, private or hybrid. Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet, Using the Interbasically a step on from Utility Computing a collection/group of integrated and networked hardware, software and Internet infrastructure is called a platform. 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).
- 4. Cloud Summary outline Cloud computing is an umbrella term used to refer to Internet based development and services Introduction to cloud context o Technology context: multi-core, virtualization, 64-bit processors, parallel computing models, big-data storages… o Cloud models: IaaS (Amazon AWS), PaaS (Microsoft Azure), SaaS (Google App Engine) A number of characteristics define cloud data, applications services and infrastructure: o Remotely hosted: Services or data are hosted on remote infrastructure. o Ubiquitous: Services or data are available from anywhere. o 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. Cloud computing metaphor: For a user, the network elements representing the provider-rendered services are invisible, as if obscured by a cloud.

How to use a Cloud storage ? … (ex: One Drive) Step 1 On the Start screen, tap or clickOneDrive to open the OneDrive app. Step 2 Tap or click folders to browse to the location on OneDrive where you want to add the files. Step 3 Swipe in from the top or bottom edge of the screen or right-click to open the app commands, and then tap or clickAdd files.
- 7. Moving and Downloading your files…. To move files to OneDrive using File Explorer When you move files, you're removing them from your PC and adding them to OneDrive. Drag files from the file list in the right pane to OneDrive in the left pane. Getting to your files from anywhere When your files are in OneDrive, you can get to them from any device, even if something happens to your PC. You can go to the OneDrive website, or you can use one of the mobile apps for Android, iOS, or Windows Phone.
- 8. Benefits of Cloud Computing On-demand self-service Broad network access Rapid elasticity Measured service Lower costs
- 9. On-demand Self-Service Clients can provision computer resources without the need for interaction with cloud service provider personnel.
- 10. Reliability The scale of cloud computing networks and their ability to provide load balancing and failover makes them highly reliable, often much more reliable that what you can achieve in a single or organization.
- 11. Rapid Elasticity The system can add resources by either scaling up systems (more powerful computers) or scaling out systems (more computers of the same kind), and scaling may be automatic or manual.
- 12. Broad Network Access Access to resources in the cloud is available over the network using standard methods in a manner that provides platform-independent access to clients of all types.
- 13. Lower Costs Because cloud networks operate at higher efficiencies and with greater utilization, significant cost reductions are often encountered.
- 14. Measured Service The use of cloud system resources is measured, audited and reported to the customer based on a metered system. A client can be charged based on a known metric such as amount of storage used, number of transactions, network input/output, amount of processing power used and so forth.
- 15. Answer: The Cloud Computing? Typical requirements and models: o platform (PaaS), o software (SaaS), o infrastructure (IaaS), o Services-based application programming interface (API) A cloud computing environment can provide one or more of these requirements for a cost Pay as you go model of business When using a public cloud the model is similar to renting a property than owning one. An organization could also maintain a private cloud and/or use both.

- 20. SECURITY Cloud computing security or, more simply, cloud security is an evolving sub-domain of computer security, network security, and, more broadly, information security. It refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing. Organizations use the Cloud in a variety of different service models (SaaS, PaaS, and IaaS) and deployment models (Private, Public, and Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: security issues faced by cloud providers (organizations providing software-,platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers
- 21. STORAGE Cloud storage is a model of data storage where the digital data is stored in logical pools, the physical storage spans multiple servers (and often locations), and the physical environment is typically owned and managed by a hosting company. These cloud storage providers are responsible for keeping the data available and accessible, and the physical environment protected and running. People and organizations buy or lease storage capacity from the providers to store end user, organization, or application data. Cloud storage services may be accessed through a co-located cloud compute service, a web service application programming interface (API) or by applications that utilize the API, such as cloud desktop storage, a cloud storage gateway or Web-based content management systems.
- 23. What is Open Stack? Open Stack is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. The project aims to deliver solutions for all types of clouds by being simple to implement, massively scalable, and feature rich.
- 24. Similar Concepts Grid computing — "A form of distributed and parallel computing, whereby a 'super and virtual computer' is composed of a cluster of networked, loosely coupled computers acting in concert to perform very large tasks." Mainframe computer — Powerful computers used mainly by large organizations for critical applications, typically bulk data processing such as: census, industry and consumer statistics, police and secret intelligence services; enterprise resource planning; and financial transaction processing. Utility computing — The "packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility, such as electricity." Peer-to-peer — A distributed architecture without the need for central coordination. Participants are both suppliers and consumers of resources (in contrast to the traditional client–server model).

Editor's Notes
- #17: ScalabilityInfrastructure capacity allows for traffic spikes and minimizes delays. ResiliencyCloud providers have mirrored solutions to minimize downtime in the event of a disaster. This type of resiliency can give businesses the sustainability they need during unanticipated events. Homogeneity: No matter which cloud provider and architecture an organization uses, an open cloud will make it easy for them to work with other groups, even if those other groups choose different providers and architectures. On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider. Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). Resource pooling. Multi-tenant model.. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines. Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). <number>
