  • Information Technology Lecturer(Dean smith)
  •  Patrico Tyrell  Shanay Allen  Chantal Gardner  Codia Grinian
  •  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.
  •  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.
  •  on-demand self service  rapid elasticity  measured service  broad network access  resource pooling
  •  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.
  •  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
  •  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
  •  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.
  • 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
  • This represents the cloud computing system layout
  • 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
  • There are two systems that provide access to computing resources in a similar way The two systems are: Mainframe Client Server
  • 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.
  • 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)
  •  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.
  • 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.
  • 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.
  •  Usually involves:  Calculating the value of assets  Conduct an impact analysis  Determine its associated risk
  •  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.
  • - 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
  •  In concluding, cloud computing provides greater flexibility, faster page loading and plays an important role in business sustainability
