  Why there isso much buzz?The interesting thing about cloud computing is that we've redefined cloud computing to include everything that we already do. I can't think of anything that isn't cloud computing with all of these announcements. 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, Oracle

  What Cloud CanDo?Developer/Startups - Get an easy access for required resources.Increased Reliability Easy scale up and scale out in minutesPay Per Usage - Cost reduction and flexibilityBoon for SaaS?Easy maintenance (!= No maintenance)“Big Data” computations can be done by you/me – Think Hadoop?Great for load/stress/performance testing - Don’t worry about boxes!7

  What Cloud Can’tDo?Moving to cloud doesn’t mean no system administration.Increasing resources doesn’t compensate for bad architecture of your system/application.Still configuration and versioning issues with large cluster of machines.Performance and Scaling are more than problems with resourcesApplications/Systems migration is not just a click away9

  Cloud Concerns???Security - Don’t you trust the bank to save your money . Sensitive and mission critical data?Data Control – Where and how the data is stored and who can access it?.Private Clouds -Where is the flexibility?Image backups/versioning – Headaches with config changesAnother 100+ ??? 13
