This document provides an overview of cloud computing, including its service models (SaaS, PaaS, IaaS), deployment models (private, public, hybrid, community clouds), advantages like flexible pricing and scalability, and disadvantages like security concerns and dependence on internet connectivity. Key technologies that enable cloud computing are discussed, such as virtualization and its use of hypervisors. Common applications of cloud computing are also mentioned.

- 5. Working definition of Cloud ComputingCloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

- 8. Cloud Service ModelsCloud Software as a Service (SaaS)---Use provider’s applications over a network Cloud Platform as a Service (PaaS)---Deploy customer-created applications to a cloud Cloud Infrastructure as a Service (IaaS)---Rent processing, storage, network capacity, and other fundamental computing resources
- 9. Cloud Deployment ModelPrivate cloud - enterprise owned or leasedCommunity cloud- shared infrastructure for specific communityPublic cloud-sold to the public, mega-scale infrastructureHybrid cloud-composition of two or more clouds

- 15. Role of Open SourceOpen source software plays an important role in cloud computing by allowing it basic software elements — virtual machine images and appliances — to be created from easily accessible componentsOpen source is shaping cloud - by providing the raw material upon which many private and public clouds are built.

- 17. Are you in Cloud?Google Docs: Online word processing,spreadsheet, presentations and collaboration software.Picasa: photo sharing siteYouTube: Online storage of videos.Webex: Online meetings. Gmail: Online email accountGliffy: Online diagram drawing.Yahoo! Calendar: An online calendar.Linkedln: Social networking for business.The business answer to MySpace and FaceBook.Picnik: Online photo editing.Blogger: A service for online publishing blogs.Google: search engineFlickr: photo sharing siteAnd many more…..

- 19. Future WorkWith Saas, Iaas, Paas the model “Everything as a service” is on the verge of development.
- 20. At the moment, this is not clear which kind of measures, tools are taken to guarantee the privacy of dataThere is still hindrance in the path to achieve cloud computing due to non availability of toolsThere should be scenario for automatic adjustment of bandwidth as traffic increases
- 21. Distributed Hybrid Cloud Architecture
- 22. ConclusionBenefits of Highly Professional Computing made available to all sizes of Business.No upfront investment – Encourages innovation. Innovators are free to focus on the innovation rather than the logistics of finding and managing resources that enable the innovation.Key Opportunity for application and infrastructure vendors.Environmental Friendly.
- 23. Cloud Computing – Tomorrow…All IT companies throwing resources into cloudcomputing .It will affect all levels of computational system, from casual user to software developers, IT managers, even hardware manufacturer. It seems like much of world’s digital information willbe living in cloudsTechnology will evolve from services into fullfledged operating systems
- 25. Hmm… Cloud computingseems less cloudy now
