  5. Cloud Concepts, Enabling-technologies, and Models: The Cloud Context Wipro Chennai 2011

  6. Evolution of Internet Computing scale deep web Data-intensive HPC, cloud web Semantic discovery Data marketplace and analytics Social media and networking Automate (discovery) Discover (intelligence) Transact Integrate Interact Inform Publish time Wipro Chennai 2011

  7. Top Ten Largest Databases Ref: http://www.focus.com/fyi/operations/10-largest-databases-in-the-world/ Wipro Chennai 2011

  8. Challenges Alignment with the needs of the business / user / non-computer specialists / community and society Need to address the scalability issue: large scale data, high performance computing, automation, response time, rapid prototyping, and rapid time to production Need to effectively address (i) ever shortening cycle of obsolescence, (ii) heterogeneity and (iii) rapid changes in requirements Transform data from diverse sources into intelligence and deliver intelligence to right people/user/systems What about providing all this in a cost-effective manner? Wipro Chennai 2011

  9. Enter the cloud • Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like the electricity grid. • The cloud computing is a culmination of numerous attempts at large scale computing with seamless access to virtually limitless resources. • on-demand computing, utility computing, ubiquitous computing, autonomic computing, platform computing, edge computing, elastic computing, grid computing, … Wipro Chennai 2011

  10. “Grid Technology: A slide from my presentationto Industry (2005) Hmmm…sounds like the definition for cloud computing!!!!! Emerging enabling technology. Natural evolution of distributed systems and the Internet. Middleware supporting network of systems to facilitate sharing, standardization and openness. Infrastructure and application model dealing with sharing of compute cycles, data, storage and other resources. Publicized by prominent industries as on-demand computing, utility computing, etc. Move towards delivering “computing” to masses similar to other utilities (electricity and voice communication).” Now, Wipro Chennai 2011

  11. It is a changed world now… • Explosive growth in applications: biomedical informatics, space exploration, business analytics, web 2.0 social networking: YouTube, Facebook • Extreme scale content generation: e-science and e-business data deluge • Extraordinary rate of digital content consumption: digital gluttony: Apple iPhone, iPad, Amazon Kindle • Exponential growth in compute capabilities: multi-core, storage, bandwidth, virtual machines (virtualization) • Very short cycle of obsolescence in technologies: Windows Vista Windows 7; Java versions; CC#; Phython • Newer architectures: web services, persistence models, distributed file systems/repositories (Google, Hadoop), multi-core, wireless and mobile • Diverse knowledge and skill levels of the workforce • You simply cannot manage this complex situation with your traditional IT infrastructure: Wipro Chennai 2011
