Types of Cloud Computing Public Cloud: Computing infrastructure is hosted at the vendors premises. Private Cloud: Computing architecture is dedicated to the customer and is not shared with other organizations. Hybrid Cloud: Organizations host some critical, secure applications in private clouds. Not critical applications are hosted in the public cloud Cloud bursting: the organization uses its own infrastructure for normal usage, but cloud is used for peak loads. 8.

Classification of Cloud Computing based on Service Provided Infrastructure as a service (IaaS) Offering hardware related services using the principles of cloud computing. These could include storage services (database or disk storage) or virtual servers. Amazon EC2, Amazon S3, Rackspace Cloud Servers and Flexiscale. Platform as a Service (PaaS) Offering a development platform on the cloud. Googles Application Engine, Microsofts Azure, Salesforce.com, s force.com . Software as a service (SaaS) Including a complete software offering on the cloud. Users can access a software application hosted by the cloud vendor on pay- per-use basis. This is a well-established sector. Salesforce.coms offering in the online Customer Relationship Management (CRM) space, Googles gmail and Microsofts hotmail, Google docs. 44.
