Licklider introduced the idea of "intergalactic computer network Amazon Web Services provided cloud-based services 20022009 as Web 2.0 become popular, Google and others started to offer browser-based enterprise applications Cloud computing service is being common in our life. Nowadays 5. What is cloud computing? Internetbased servicesCloud computing Internetbased resources 6. Types of cloud 1. Public cloud 2. Private cloud 3. Hybrid cloud (combination of public and private cloud) 7. Public Cloud1.Is established where several organizations have similar requirements and seek to share infrastructure so as to appliance.2. Service providers can make their computing resources available online for the public. 8. Private cloud eg. iCylanAPPEnables you to remote access the sensitive applications of enterprises by smart phones or tablet device anywhere and anytime. 9. Services models of cloud computing Platform as a service (PaaS)Software as a service (SaaS)Definition development environments as a service Providing developers with platform( server,memory,s oftware,hardware)application as a service to customer providing end users with access to the data and softwareapplications development tools Building games Examples1.
