Cloud computing describe how computer programs are hosted and operate over the internet. What is Cloud Computing? 3 Prepared By : Bhavin Tank CCSIT, Junagadh. Cloud Computing

4. Types Of Clouds Public Cloud: the services are delivered to the client via the Internet from a third party service provider. Example: Amazon, Yahoo, Google Private Cloud: these services are managed and provided within the organization. There are less restriction on network bandwidth, fewer security exposures and other legal requirements compared to the public Cloud. Example: HP Data Centers Hybrid Cloud: allow data and/or applications to be moved from one cloud to another. This can be a combination of private and public clouds that support the requirement to retain some data in an organization. 4 Prepared By : Bhavin Tank CCSIT, Junagadh. Cloud Computing
