What is Cloud Computing?



Traditional business applications and platforms are too complicated and expensive. They need a data center, a complex software stack and a team of experts to run them. This short video explains what Cloud Computing is and why it's faster, lower cost and doesn't eat up your valuable IT resources.

Cloud Computing is a much easier and affordable way to run your business. Cloud Computing is an easy way to improve your company's bottom line, greatly. While allowing you to work from any smart phone, or computer anywhere in the world at any time. This animation is produced by Fahai Media Google Tech Talk May 8, 2009 ABSTRACT Presented by Kevin Lai Cloud computing and its predecessors, grid and utility computing, all address shared, on-demand computing at scale. To achieve sufficient scale to amortize costs, cloud computing emphasizes saving human time through 1) automated management, 2) easier programming using systems like MapReduce and Hadoop, and 3) shared and open access. Existing architectures for achieving these goals are composed of largely isolated resource allocation sub-systems (e.g., for MapReduce scheduling, virtualization, CPU, network bandwidth, power, etc.) These sub-systems have global impact, but local visibility, which can cause them to work against each other. The shared, open nature of cloud computing systems requires balancing the need to do efficient local allocation of resources and the need to regulate and differentiate applications globally. We take a clean slate approach to designing a cloud computing architecure. We apply economic mechanisms to resources at every layer from the high-level Hadoop system through the allocation of virtualized resources to physical servers. We find that this approach 1) simplifies system design, 2) provides more high-level optimization opportunities, 3) provides greater control over predictability, and 4) increases overall application utility. Kevin Lai is a Research Scientist in the Social Computing Lab at HP Labs. He has done research on operating systems, mobile and wireless networking, network measurement, and economic approaches to resource allocation. He is currently the lead developer of the Open Cirrus cloud computing system. He received his Ph.D. in Computer Science from Stanford University. The Chief Geeks of Nasdaq and HP give the 30-second answer. There's been a lot of buzz about Cloud Computing the last few weeks. For those of us with our feet still on the ground, a panel of top CIOs and CTOs gave the executive overview at last week's Summit at Stanford. Anna Ewing invites us to think "distribution": Take high-powered enterprise technology and make it available to the masses via the internet. Russ Daniels of HP talks about the more practical aspect of cloud computing. He believes the essential ingredient is virtualization--getting someone else's computer to do your work for you. This brings down your company's operational costs, freeing up capital while making your company overall more efficient. But it's not all about the bottom line, says's Polly Sumner. Cloud computing also makes enterprise software more human -- SaaS providers are driven to deliver superior customer service, since clients can leave at any time. Imagine that -- technology forcing us to be more human. Check out the video for more. A complete introduction about cloud computing. How does it work ? .. & many more.. !!
