  6. 6. What is Public Cloud?<br />Public Cloud (external Cloud)<br />Public cloud or external cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who bills on a fine-grained utility computing basis.<br />
  7. 7. What is Private Cloud?<br />Private Cloud (Internal Cloud or Corporate Cloud) <br />Private Cloud is a marketing term for a proprietary computing architecture that provides hosted services to a limited number of people behind a firewall.<br />Advances in virtualization and distributed computing have allowed corporate network and datacenter administrators to effectively become service providers that meet the needs of their "customers" within the corporation.<br />
  8. 8. What is Hybrid Cloud?<br />A hybrid cloud environment consisting of multiple internal and/or external providers "will be typical for most enterprises".By integrating multiple cloud services users may be able to ease the transition to public cloud services while avoiding issues such as PCI compliance.<br />Another perspective on deploying a web application in the cloud is using Hybrid Web Hosting, where the hosting infrastructure is a mix between Cloud Hosting for the web server, and Managed dedicated server for the database server.<br />
