What is Cloud?Cloud is a metaphor for Internet, based on how it is depicted in computer network, diagrams, and is an abstraction for the complex infrastructure it conceals.What is Cloud Computing?Leveraging 3rd party computing capability over the network to cut costs, increase scale, improve agility, and access best practices..

Cloud Deployment Models4 Cloud Deployment Models:

Private cloud. The cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on premise or off premise.Community cloud. The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise.Public cloud. The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.Hybrid cloud. The cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting).

8Essential Cloud Characteristics On-demand self-service Broad network access Resource pooling- Location independence Rapid elasticity Measured service

Security in CloudTwo Broad Categories of Cloud Security Security issues faced by cloud providers (organizations providing services via the cloud). The providers must ensure the security & protection of their infrastructure and clients data and applications.

Security issues faced by the cloud customers. The customer must ensure that the provider has taken proper security measures to protect their information.Dimensions of Cloud SecuritySecurity and Privacy Data Protection Identity Management Physical and Personal Security Availability Application Security PrivacyCompliance Business Continuity and Data Recovery Logs and Audit Trails Unique Compliance Requirements

The Future A solid majority of technology experts and stakeholders expect that by 2020, most users will perform most computing and communicating activities through connections to servers operated by outside firms. This does not mean, however, that most of these experts think the desktop computer will disappear soon. The majority sees a hybrid life in the next decade, as some computing functions move towards the cloud and others remain based on personal computers.Courtesy: Janna Quitney Anderson, Elon University and Lee Rainie, Pew Internet & American Life Project (June 11, 2010)
