  3. 3. <ul><li>Evolution </li></ul>Cloud Computing Evolution <ul><li>Evolution </li></ul>Web 3.0 with Cloud Computing Web 2.0 with Collobaration Anyone can Transact with the Web Technologies involved 1.Basic HTML 2.Slow Internet Connections Web 1.0 with Static Web Content Anyone can participate Technologies involved 1.Writing in the Web 2.XML 3.Communities,blogs etc 4.Web Services 5.Better Network connections Anyone can Innovate OnDemand
  4. 4. What s Cloud Computing <ul><li>Cloud is collection of resources which can be accessed over the internet as utilities compared to apps running on desktops/or on dedicated resources. </li></ul><ul><li>Cloud computing enables the building/running of applications on the Cloud. </li></ul>Virtualization Utility Computing Software as a Service
  5. 5. Why Cloud Computing and the Usage <ul><li>Facilitates easy deployment of applications ,without the complexity of managing the associated hardware. </li></ul><ul><li>Reduced Cost due to the OnDemand pricing model. </li></ul><ul><li>Enables sharing of resources among large pool of users.(Potential Security Risk) </li></ul><ul><li>Scalable since the infrastructure </li></ul><ul><li>Usage </li></ul><ul><ul><ul><li>Resources can be accessed as a Service over the internet which can be a Application(SaaS),Platform(PaaS),Infrastructure(IaaS),storage (DataStorage as a Service). </li></ul></ul></ul><ul><ul><ul><li>Applications are accessed as a Service using traditional protocols like SOAP etc. </li></ul></ul></ul>
  6. 6. Technical Aspects of Cloud <ul><li>What are the key drivers of a Cloud Platform ? OR How is a cloud constructed and enabled? </li></ul><ul><li>Virtualization </li></ul><ul><li>Utility Computing </li></ul><ul><ul><li>Utility computing is a metered service of computing resources. </li></ul></ul><ul><ul><ul><li>Virtualization is the process by which the resources are abstracted as number of virtual resources including OS,server,DB,network. </li></ul></ul></ul><ul><ul><ul><ul><li>Ex.OS Virtualization is one in which the Virtualization software partitions the hardware and emulates to run with different OS. </li></ul></ul></ul></ul><ul><li>IaaS – Consuming InfraStructure as a Service </li></ul><ul><li>PaaS – Consuming Platform related operations as Services </li></ul><ul><li>SaaS – Consuming enterprise applications as Services </li></ul>
  7. 7. Cloud Computing Platforms <ul><li>Amazon AWS (http://aws.amazon.com/) </li></ul><ul><ul><ul><li>Amazon EC2 – Amazon Elastic Cloud </li></ul></ul></ul><ul><ul><ul><li>Amazon S3 – Storage as a Service </li></ul></ul></ul><ul><li>Google App Engine </li></ul><ul><li>SalesForce </li></ul><ul><li>Microsoft Azure Platform – Cloud Platform hosted in Microsoft Data Center </li></ul><ul><li>IBM Cloud </li></ul>
