  3 Cloud computing isinternet-based computing in which large groups of remote servers are networked to allow 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 a very simple graphical interface or API (Applications Programming Interface). What is Cloud Computing?

  5  Cloud computingis an umbrella term used to refer to Internet-based development and services  Introduction to a cloud context o Technology context: multi-core, virtualization, 64-bit processors, parallel computing models, big-data storage… o Cloud models: IaaS (Amazon AWS), PaaS (Microsoft Azure), SaaS (Google App Engine)  Several 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!

  How to usea 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 click add files.

  Moving and Downloadingyour 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.

   On-demand self- service Broad network access  Rapid elasticity  Measured service  Lower costs Benefits of Cloud Computing
• 10.
  Clients can provision computerresources without the need for interaction with cloud service provider personnel. On-demand Self-Service
• 11.
  Reliability The scale ofcloud computing networks and their ability to provide load balancing and failover make them highly reliable, often much more reliable that what you can achieve in a single or organization.
• 12.
  Rapid Elasticity The systemcan 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.
• 13.
  Broad Network Access Accessto resources in the cloud is available over the network using standard methods in a manner that provides platform- independent access to the clients of all types
• 14.
  Lower Costs Because cloudnetworks operate at higher efficiencies and with greater utilization, Significant cost reductions are often encountered.
• 15.
  Measured service The useof 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 the amount of storage used, number of transactions, network input/output, amount of processing power used, and so forth.

  Answer: The CloudComputing?  Typical requirements and models: o Platform (PaaS), o Software (SaaS), o Infrastructures (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 to owning one.  An organization could also maintain a private cloud and/or use both.

  SECURITY  Cloud computingsecurity 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 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 several 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.

  STORAGE  Cloud Storageis 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 service may be accessed through a collocated 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.
