 Definition:  An infrastructure that is used to store and share data over the internet  Three different types of cloud computing:  Software as a Service  Platform as a Service  Infrastructure as Service

 Concept of Cloud Computing dates back to the 1960’s  J.C.R Licklider- Visioned everyonein the world being interconnected, and accessing data from anywhere  John McCarthy- idea that computation as a public Service  Salesforce.com introduced.

 Software as a service  Salesforce  Google Apps  Utility Computing  Storage and virtual Servers  Web services in a cloud  Strike Iron  Google Maps  Credit Card Processing

 Platform as a Service  Force.com  Coghead  Managed Service Providers  Security Services  Service Commerce Platforms  Rearden Commerce  Ariba  Internet Integration  Better Faster Cheaper!!!  Slicing Bread

 Online medical records  Phone applications  OnLive (video games)

 Cloud computing can increase the ability of business intelligence through increased data collection, storage and sharing.  e.g. A small business can use accounting services like intuit.com instead of staffing an accountant.  The business would also have instant access to accounting figures.  However, regulation and auditing procedures will usually lag technology & crime.  With this evolving technology, a single person could cause an unprecedented negative impact on society.

 Access to information anywhere and anytime  You don’t have to maintain infrastructure for applications  Reduced labor costs  Outsourcing equipment cost  Google’s “green” data centers  Less electricity being used  Reduced power waste  A 5 mile trip = 10,000 Google searchs  2 facilities using 100% recycled water

 Changes in the application happen without your knowledge or consent.  Your data is not directly in your hands, but in the hands of a third party.  You are dependent on your internet connection (could be a major problem if the information is critical)  Compliance risk a.k.a. auditing risk.  Data protection and encryption problems  Lock-in (hard to transfer from one provider to another since it would involve a massive level of data migration)  The technology has not yet matured
