Cloud computing presentation

  1. 1. Information Technology Lecturer(Dean smith)
  2. 2.  Patrico Tyrell  Shanay Allen  Chantal Gardner  Codia Grinian
  3. 3.  The ‘cloud’ in cloud computing is defined as the set of hardware, networks, storage, services, and interfaces that combine to deliver aspects of computing as a Service.  Cloud computing is the ability to access a pool of computing resources owned and maintained by a third party via the Internet.
  4. 4.  An example of cloud computing in action is demonstrated by web based email service providers such as Yahoo and Gmail which uses cloud computing to store software and users emails.
  5. 5.  on-demand self service  rapid elasticity  measured service  broad network access  resource pooling
  6. 6.  Users being able to monitor and manage computing resources as needed without the help of human administrators.  This feature promotes less interaction between servers and users, since users are able to maneuver resources on their own.
  7. 7.  This entails service been transmitted over a standard network and different devices such as laptops, mobile phones and tablets. • The rapid elasticity capability of cloud computing is the ability to scale resources both up and down as needed rapid elasticity
  8. 8.  This basically the cloud system being closely monitored and service use by users is measured and the appropriate charges are presented to consumers. • resource pooling is whereby the service provider put together a group of resources to work together to meet users needs. resource pooling
  9. 9.  Private cloud (also called internal cloud or corporate cloud) is a marketing term for a proprietary computing architecture that provides hosted services to a limited number of people behind a firewall.  Private cloud computing can also be adopted when business owners and application owners use the corporate IT as a standard infrastructure on the request of new business service, not knowing how complex it is at the time.
  10. 10. PUBLIC CLOUD  A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.  Easy and inexpensive set-up because hardware, application and bandwidth costs are covered by the provider.  Scalability to meet needs.  No wasted resources because you pay for what you use. Benefits of PUBLIC Cloud
  11. 11. This represents the cloud computing system layout
  12. 12. The main characteristics of cloud computing are as follows:  Virtualization – which allows servers and storage devices to be shared giving users the impression that they full control over the resource that is being accessed  Multi-tenancy – which enables sharing of resources and costs across a large pool of users  Ease of maintenance – which means that because applications are not installed on the user’s computer there is no need to visit each computer to maintain the application
  13. 13. There are two systems that provide access to computing resources in a similar way The two systems are: Mainframe Client Server
  14. 14. A Mainframe is a large digital computer serving 100-400 users.  Main Frames also run multiple different instances of operating systems at the same time thereby operate not as a single computer but as a number of virtual machines. This technique of virtual machines allows applications to run as if they were on physically distinct computer.
  15. 15. Mainframes allow multiple users to share the CPU time and is similar to the multi- tenancy concept used by cloud computing to make available to a large number of users the resources of the main frame  Users gain access through specialized terminals or, from personal computers equipped with terminal emulation software (green screen that you use at work)
  16. 16.  Client Server System - A computing system composed of two logical parts: a server, which provides information or services, and a client, which requests them. On a network, for example, users can access server resources from their personal computers using client software.  Client/server systems are constructed so that the resource that is to be accessed can reside on a central computer, known as a server, and is shared among several users. Users access the server through a client or server application and they have the impression that they have full control over the resources that is being access.
  17. 17. The server opens connections to the resource being accessed and in so doing enables sharing of resources across a large pool of users as it allows many users to use a single resource which is similar to the multi-tenancy characteristic of cloud computing.
  18. 18. CLOUD COMPUTING ON COMPUTER SECURITY  In today’s world more IT professionals are using cloud computing to protect their firms computer system. Instead of running anti-virus products on their own network, companies are buying security layers from cloud computing specialists. These would be security specialists like Kasperksy Lab and AVE.
  19. 19.  Usually involves:  Calculating the value of assets  Conduct an impact analysis  Determine its associated risk
  20. 20.  Cloud computing has helped to sustain businesses of all sizes. It helps to lower cost and fits with the budget the company is working with.  It also time provide them with a more sustainable, ecologically-friendly alternative to traditional IT infrastructure.
  21. 21. - The reason behind cloud system providing a more sustainable, ecologically-friendly alternative is that; When the businesses uses the cloud system 1) Fewer physical components are used, hence reducing the amount of energy used 2) It reduces the carbon emission
  22. 22.  In concluding, cloud computing provides greater flexibility, faster page loading and plays an important role in business sustainability
