  2. 2. A Brief History of Cloud Computing  “cloud computing” concepts date back to the 1950s when large-scale mainframes were made available to schools and corporations  A couple decades later in the 1970s, IBM released an operating system called VM that allowed admins on their System/370 mainframe systems to have multiple virtual systems  In the 1990s, telecommunications companies that had historically only offered single dedicated point–to-point data connections started offering virtualized private network connections >>>>See more 2 Cloud Computing

  8. 8. SAAS : able to access software applications over the internet. Often referred to as software-on-demand and utilizing it is akin to renting software rather than buying it. There are no setup costs with SaaS, as there often are with other applications SaaS is scalable with upgrades available on demand Access to Software as a Service is compatible across all internet enabled devices As long as there is an internet connection, applications are accessible from any location >>>>See More Cloud Computing 8

  17. 17. Public Clouds : The most recognizable model of cloud computing to many consumers is the public cloud model, under which cloud services are provided in a virtualized environment, constructed using pooled shared physical resources, and accessible over a public network such as the internet. To some extent they can be defined in contrast to private clouds which ring-fence the pool of underlying computing resources, creating a distinct cloud platform to which : Amazon Example only a single organization has access. Public clouds, however, provide >>>See More multiple clients using the same services to Cloudshared infrastructure Computing 17
  18. 18. Private Cloud : A private cloud is a particular model of cloud computing that involves a distinct and secure cloud based environment in which only the specified client can operate. As with other cloud models, private clouds will provide computing power as a service within a virtualized environment using an underlying pool of physical computing resource. However, under the private cloud model, the cloud (the pool of resource) is only accessible by a single organization Example: HP Data Centers providing that organization with greater control and privacy >>>See More Cloud Computing 18
  19. 19. Hybrid Clouds : A hybrid cloud is an integrated cloud service utilizing both private and public clouds to perform distinct functions within the same organization. All cloud computing services should offer certain efficiencies to differing degrees but public cloud services are likely to be more cost efficient and scalable than private clouds. Therefore, an organization can maximize their efficiencies by employing public cloud services for all non-sensitive operations, only relying on a private cloud where they require it and ensuring that all of their platforms are >>>See More seamlessly integrated.

  20. 20. Community Cloud : A community cloud is a cloud service model that provides a cloud computing solution to a limited number of individuals or organizations that is governed, managed and secured commonly by all the participating organizations or a third party managed service provider. >>>See More Cloud Computing 20
  21. 21. Distributed cloud : Cloud computing can also be provided by a distributed set of machines that are running at different locations, while still connected to a single network or hub service. Examples of this include distributed computing platforms such as BOINC and Folding@Home. >>>See More Cloud Computing 21
  22. 22. Security Cloud : What's one of the biggest hindrances slowing the migration to cloud computing? Concerns over security, that's what. Companies want to know where their data is, who has access to it and that it's protected. These companies target three key areas for cloud security: security in the cloud, security for the cloud and security from the cloud. >>>See More Cloud Computing 22
  23. 23. Storage Cloud : The cloud seems made for online storage. At its core, the cloud offers a nearly infinite space to store data, whether it's for backup, business continuity, disaster recovery or any of the other myriad purposes. And for solution providers, offering Storage-as-a-Service, or offering the ability to back up or store data via the Internet, is creating new business opportunities. The ability to dynamically expand or scale back storage capacity on demand is a powerful proposition, and solution providers and enterprises want to >>>See More ensure they're trusting their data to the Cloudright cloud storage vendor.

  31. 31. Conclusions : To summarize, the cloud provides many options for the everyday computer user as well as large and small businesses. It opens up the world of computing to a broader range of uses and increases the ease of use by giving access through any internet connection. However, with this increased ease also come drawbacks. You have less control over who has access to your information and little to no knowledge of where it is stored. You also must be aware of the security risks of having data stored on the cloud. The cloud is a big target for malicious individuals and may have disadvantages because it can be 31 accessed through an unsecured internet connection Cloud Computing
