  1. LEADING FACET OF NETWORKING- CLOUD COMPUTING

  2. WHAT IS CLOUD ?? Infrastructure provided by the service provider to build internet application. The service provided by cloud are categorize > Software As a Service > Infrastructure As a Service > Platform As a Service > Database As a Service > Software plus Service

  3. Cloud Computing- CONCEPT • Cloud computing refers to the use and access of multiple server-based computational resources via a digital network (WAN), Internet connection using the World Wide Web  etc.. Cloud users may access the server resources using a computer, netbook, pad computer, smart phone, or other device. • In cloud computing, applications are provided and managed by the cloud server and data is also stored remotely in the cloud configuration. Users do not download and install applications on their own device or computer; all processing and storage is maintained by the cloud server. The on-line services may be offered from a cloud provider or by a private organization.

  4. HISTORY • Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic, and utility computing. Details are abstracted from end-users, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them. • The actual term "cloud" borrows from telephony in that telecommunications companies, who until the 1990s offered primarily dedicated point-to-point data circuits, began offering Virtual Private Network (VPN) services with comparable quality of service but at a much lower cost.

  5. NEEDS • To reduce the IT operations and management costs • Cloud model of software architecture.

  6. ISSUES RELATED TO CLOUD COMPUTING • Cloud computing may create a dependence on the provider (Google, Amazon) and may make it difficult to move to another platform. • Google itself admits that Google App Engine is targeted at consumer applications, not businesses. • There’s always the risk that the Cloud provider may change business models or even go out of business.

  7. CHARACTERISTICS • Measured Service •  Rapid Elasticity • On-Demand Self-Service • Ubiquitous Network Access • Resource Pooling

  8. ARCHITECTURE

  9. TYPES OF CLOUD • Public Cloud • Private Cloud • Community Cloud • Hybrid Cloud • Combined Cloud

  10. PROS AND CONS : • ADVANTAGES: • Software as a Subscription • Reduced Software Maintenance • Increased Reliability • Environmentally Friendly • Cost Reduction • Portability/Accessibility

  11. DISADVANTAGES: • Bandwidth could bust your budget • App performance could suffer • Data might not be cloud-worthy • Too big to scale

  12. Future of CLOUD COMPUTING • The 55% of respondents believe that cloud computing has a lower total cost of ownership (TCO). • 74 percent of respondents indicated that cloud computing would either lead to an increase in hiring or have no impact, while rest of respondents expected any decrease in hiring based on cloud adoption. • 39 percent indicating that the cloud would make for less or more complex environments.

  13. Conclusions • Cloud Computing is the fastest growing part of IT • • Tremendous benefits to customers of all sizes • • Cloud services are simpler to acquire and scale up or down

  14. Conclusions • Public clouds work great for some but not all applications • Private clouds offer many benefits for internal applications • Public and private clouds can be used in combination
