Cloud Computing
What is Cloud Computing?
• “Cloud” is simply a metaphor for the internet
• Users do not have or need knowledge, control, ownership in the computer infrastructure
• Users simply rent or access the software, paying only for what they use
• Simple Introduction to Cloud Computing
History of Cloud Computing
• Concept dating back to the 1960’s by John McCarthy, a computer scientist, brought up the idea that "computation may someday be organized as a public utility”
• Idea that revolutionized Cloud Computing: Moving from clustering computing to grid computing
– Clustering
– Grid
• “In some ways, the cloud is a natural next step from the grid-utility model,” said Frank Gens, an analyst at the research firm IDC
The “Super Computer” in the Sky
• Two ways of building a “super computer” with enough power that users can plug into according to their needs at a particular time:
– Blue Gene Approach
– Google's Approach
Early Leaders in the Industry
• In 2007, Microsoft made available free software, live.com that connects its Windows operating system to software services delivered on the Internet
• Launched in July 2002, Amazon Web Services provided online services for other web sites or client-side applications
• 3tera launched its AppLogic system in February, 2006
• IBM’s system introduced in the mid 2000’s is called Blue Cloud
Potential Issues
• Data residency – time delay between data being requested and delivered
• Security and confidentiality of data being stored outside the company
• Business buy-in; convincing companies of the infrastructure and reliability
Functionality
• Cloud computing is an emerging technology that is revolutionizing IT infrastructures and flexibility, and software as a service (SaaS)
• During this economic time of recession, there are huge cost-reduction pressures and cloud computing allows businesses to do just that by tapping into cloud computing platforms on a pay-as-you-go basis
• Customer retention is vital, especially today in our economy
