  • Take the poll
    Have you used the cloud
    For one, two, three, or more of these services
  • ScalabilityInfrastructure capacity allows for traffic spikes and minimizes delays.
    ResiliencyCloud providers have mirrored solutions to minimize downtime in the event of a disaster. This type of resiliency can give businesses the sustainability they need during unanticipated events.
    Homogeneity: No matter which cloud provider and architecture an organization uses, an open cloud will make it easy for them to work with other groups, even if those other groups choose different providers and architectures.
    On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.
    Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
    Resource pooling. Multi-tenant model.. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.
    Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
    Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts).

    1. 1. Cloud Computing By :-T. Mur@li sankaran
    2. 2. INTRODUCTION  Cloud computing is a marketing term for technology  End - user do not require any knowledge regarding system  Users can access and use facilities through a web browser
    3. 3. What is Cloud Computing?  Cloud computing is used to describe a variety of different types of computing concepts that involve a large number of computers connected through a real-time communication network  cloud computing is the delivery of computing as a service rather than a product
    4. 4. What is Cloud Computing?  Utility computing  Platform  Cloud
    5. 5. Do you Use the Cloud?
    6. 6. Cloud Computing Characteristics Common Characteristics: Massive Scale Massive Scale Resilient Computing Resilient Computing Homogeneity Homogeneity Geographic Distribution Geographic Distribution Virtualization Virtualization Service Orientation Service Orientation Low Cost Software Low Cost Software Advanced Security Advanced Security Essential Characteristics: On Demand Self-Service On Demand Self-Service Broad Network Access Broad Network Access Resource Pooling Resource Pooling 6 Rapid Elasticity Rapid Elasticity Measured Service Measured Service
    7. 7. Cloud Architecture 7
    8. 8. Service Models 1 Infrastructure as a Service (IaaS) In this architecture you're buying access to raw computing hardware over the Net, such as servers or storage. 2 Software as a Service (SaaS) In this architecture you use a complete application running on someone else's system 3 Platform as a Service (PaaS) In this you develop applications using Web-based tools so they run on systems software and hardware provided by another company.
    9. 9. IaaS Examples
    10. 10. SaaS Examples
    11. 11. PaaS Examples
    12. 12. Deployment Models  Private cloud  Public cloud  Community cloud  Hybrid cloud  Personal cloud  Distributed cloud
    13. 13. Types Of Cloud
    14. 14. Advantages Can be less expensive compared to buying software and hardware Can be used from any computer or device with an Internet connection The device does not need as large of an internal storage system Compatible with most computers and operating systems Updates occur across the service
    15. 15. Disadvantages • • • • • • • Manageability Privacy & Security Data Management Federation Interoperability Virtualization, Elasticity and Adaptability APIs, Programming Models & Resource Control
    16. 16. Disadvantage s Advantages
    17. 17. CONCLUSION • CLOUD COMPUTING IS THE FASTEST GROWING PART OF IT • TREMENDOUS BENEFITS TO CUSTOMERS OF ALL SIZE • CLOUD SERVICES ARE SIMPLER TO AQUIRE • PUBLIC AND PRIVATE CLOUDS MAY BE USED IN COMBINATION
