This document provides an introduction to cloud computing, including definitions, examples of existing cloud applications, benefits, and limitations. It discusses key cloud concepts like infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Popular cloud platforms like Amazon AWS, Google App Engine, and Windows Azure are briefly introduced. Potential concerns with security, data control, and migration are also outlined. The presentation aims to explain cloud computing fundamentals and tradeoffs for developers and startups.

- 2. What is Cloud Computing?
- 3. "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." - NIST

- 5. Why there is so 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
- 6. Virtualization is not Cloud it’s just one part of Cloud
- 7. What Cloud Can Do?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

- 9. What Cloud Can’t Do?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

- 13. 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
