Cloud computing

  1. 1. cloud computing By K. Vignesh
  2. 2. Introduction: • Cloud computing is the delivery of computing services over the Internet. • Whether they realize it or not, many people use cloud computing services for their own personal needs. • For example, many people use social networking sites or webmail, and these are cloud services. • Photographs that people once kept on their own computers are now being stored on servers owned by third parties.
  3. 3. Cloud application architecture: • Infrastructure as a Service (IaaS) refers to hardware for hire, in terms of servers, storage capacity, and network bandwidth, with the application and the maintenance of that application layer remaining the responsibility of the customer. • The servers are virtualized to provide agility and flexibility. • IaaS is typically billed on a utility computing basis and amount of resources consumed (and therefore the cost) will typically reflect the level of activity.
  4. 4. Cloud application architecture(Cont): • Platform as a Service (PaaS) allows for the creation and deployment of applications and services and includes the infrastructure to host the built application. • It facilitates the quick roll-out and/or modification of operating system features.
  5. 5. Cloud application architecture(cont): • Software as a Service (SaaS) is a way of providing the same software to different customers via a network, usually the Internet. • Either the software is not hosted on the customers’ individual computers, nor is the customer responsible for the hardware that delivers the service. • In this instance a supplier takes care of the creation, updating, and maintenance of the software and, again, customers pay for what they use.

  7. 7. Cloud infrastructure model: • There are many considerations for cloud computing architects to make when moving from a standard enterprise application deployment model to one based on cloud computing. • There are public and private clouds that offer complementary benefits, there are three basic service models to consider. • IT organizations can choose to deploy applications on public, private, or hybrid clouds, each of which has its trade-offs. The terms public, private, and hybrid do not dictate location. • While public clouds are typically “out there” on the Internet and private clouds are typically located.
  8. 8. Public clouding: • Public clouds are run by third parties, and applications from different customers are likely to be mixed together on the cloud's servers, storage systems, and networks. • Public clouds are most often hosted away from customer premises, and they provide a way to reduce customer risk and cost by providing a flexible, even temporary extension to enterprise infrastructure.
  9. 9. Private clouding: • Private clouds are built for the exclusive use of one client, providing the utmost control over data, security, and quality of service. • The company owns the infrastructure and has control over how applications are deployed on it. • Private clouds may be deployed in an enterprise datacenter, and they also may be deployed at a collocation facility.
  10. 10. Hybrid clouding: • Hybrid clouds combine both public and private cloud models. • They can help to provide on-demand, externally provisioned scale. • The ability to augment a private cloud with the resources of a public cloud can be used to maintain service levels in the face of rapid workload fluctuations. • This is most often seen with the use of storage clouds to support Web 2.0 applications. • Hybrid clouds introduce the complexity of determining how to distribute applications across both a public and private cloud.
