Cloud Computing

Based on a presentation by Farhad Javidi at Course Technology

Conference 2009

The Cloud is the New Dot Com

What is Cloud Computing?

“The interesting thing about cloud computing is that we’ve redefined cloud computing to include everything that we already do. […] The computer industry is the only industry that is more fashion-driven than women’s fashion. Maybe I’m an idiot, but I have no idea what anyone is talking about. What is it? It’s complete gibberish. It’s insane. When is this idiocy going to stop? Larry Ellison during Oracle’s Analyst Day

• “• Cloud computing is simply a buzzword

used to repackage grid computing and utility computing, both of which have existed for decades.”

(Good Luck) Defining Cloud Computing• Software-as-a-Service

– “My customer resource management (CRM) system is out on the Internet!”

• Grids vs. Clouds– Shared Virtual Resources– Batch Jobs vs. Online Applications– Different Approaches to State

Management

• Network Diagrams– A service is “on a cloud somewhere”

• Virtualization Platforms & APIs– Hardware can be manipulated with

software

Grid CloudUnderlying concept Utility Computing Utility ComputingMain benefit Solve computationally

complex problemsProvide a scalable standard environment for network-centric application development, testing and deployment

Cloud Platforms

• Google Gears• Amazon Web Services• Salesforce (app Exchange)• Facebook• Adobe Air• Microsoft Azure

Cloud Benefits

• Cloud = Less Investment

(not own data center, hardware; use outside provider of servers, storage, and bandwidth)

• Cloud = Scale

(tens of thousands of server computers)

• Cloud = Flexible and Efficiency

Cloud Ecosystem• End-user applications, Software-as-a-Service (SaaS)• Platform-as-a-Service (PaaS)• Infrastructure-as-a-Service (IaaS)
