Customer have higher degree of control and transparency, comply with security standards, regulatory compliance Customer of public cloud has a low degree of degree, since security management are done by vendors Hybrid cloud combination of two or more type of clouds
-Scalability, as in flexible business model according to the size of the organization -Pay for use model. -less maintenance as in patches and updates, in this virtualized environment. Increased automation also saves cost. Flexibility and the ownership /operation of hardware all getting outsourced. . If you’ve ever used MySpace, Facebook, LinkedIn, Picasa, Flickr, Hotmail, or Gmail, then you’ve used cloud computing
concern is to trust that a company's or an individual's information is both secure and private Unplanned outages - Understanding the cloud provider’s disaster recovery and business continuity measures, negotiating strong service level agreements and disaster recovery commitments, A major concern with cloud computing is the difficulty of determining where data will be stored, and, thus, what courts have jurisdiction and what law governs the use and treatment of such data (i.e., local, state, federal, foreign, etc.). For the location of data you wouldn’t know where it is located too
Jericho Forum and CSA joined forces to push for technology to allow business , to collaborate securely in the cloud.

Cloud Computing Services & Security Concerns for Data Storage
‘ Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.’
According to Gartner
‘ Gartner defines cloud computing as a style of computing in which massively scalable IT-related capabilities are provided "as a service" using Internet technologies to multiple external customers’
Cloud Computing is internet based, real-time service and can access solution regardless of location
It is massively scalable with flexible business model
Provides a flexible pricing model, with a low upfront cost for both infrastructure and software
End up being less maintenance, promoting energy efficiency (Green IT) and cost benefits.
