Cloud computing Cloud computing Presentation Transcript

  • LOGO
  •  Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Much more efficient computing by centralizing storage, memory, processing and bandwidth. 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 thats often used to represent the Internet in flowcharts and diagrams.
  • Example : A simple example of cloud computing is Yahoo email or Gmail etc. You dont need a software or a server to use them. All a consumer would need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud ( internet) and is totally managed by the cloud service provider Yahoo , Google etc. The consumer gets to use the software alone and enjoy the benefits.
  • Analogy : ‘If you only need milk , will you buy a cow ?’ All the users or consumers need is to get the benefits of using the software or hardware of the computer like sending emails etc. Just to get this benefit (milk) why should a consumer buy a (cow) software /hardware ?

  • Cloud Architecture (1) Typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services. Front end includes the client‟s network (or computer) and the applications used to access the cloud via a user interface such as a web browser. The back end of the cloud computing architecture is the „cloud‟ itself, comprising various computers, servers and data storage devices.
  • Cloud Architecture (2)Cloud Computing Sample Architecture
  • Cloud Computing : Services (1) Infrastructure-as-a-Service (IaaS)• A service offering to provide elastic renting of computing resources. Platform-as-a-Service (PaaS)• A service offering to provide an application development and hosting platform. Software-as-a-Service (SaaS)• A service offering to provide various software applications.

  • Cloud Computing: Key Features (1) Agility improves with users ability to rapidly and inexpensively re-provision technological infrastructure resources. API accessibility to software that enables machines to interact with cloud software. Device and location independence. Multi-tenancy enables sharing of resources and costs across a large pool of users.
  • Cloud Computing: Key Features (2) Reliability is improved if multiple redundant sites are used, which makes well designed cloud computing suitable for business continuity and disaster recovery. Scalability via dynamic ("on-demand") provisioning of resources on a fine-grained, self-service basis near real- time, without users having to engineer for peak loads. Maintenance of cloud computing applications is easier, since they dont have to be installed on each users computer.
  • Cloud Computing: Key Features (3) Security could improve due to centralization of data, increased security-focused resources, etc., but concerns can persist about loss of control over certain sensitive data, and the lack of security for stored kernels. Metering means that cloud computing resources usage should be measurable and should be metered per client and application on a daily, weekly, monthly, and yearly basis.
  • Who is on the cloud ??????????
  • Cloud Computing:”it is the future”
  • Interesting Facts Despite cloud computing being in the media spotlight, only a minority of respondents (5%) say that they use it "a lot" and less than a quarter of those surveyed (19%) reveal that they only use cloud computing sparingly. Almost half of respondents (47%) admit that their company doesn‟t use cloud computing with the remaining 29% conceding that they “don‟t know” whether their organisation uses it or not. Still there is a "CLOUD CONFUSION" amongst 41% of IT professionals.
  • Conclusion Finally, cloud apps don‟t eat up your valuable IT resources. This lets you focus on deploying more apps, new projects, and innovation. The bottom line: Cloud computing is a simple idea, but it can have a huge impact on your business.
