- 3. Cloud Computing ….. It walks through the cloud (C)ANTARA&ANIK 3
- 4. What is Cloud computing ? “Any situation in which computing is done in a remote location (out in clouds), rather than your desktop or portable device” (C)ANTARA&ANIK 4
- 5. Cloud computing is a internet-based Computing, whereby Shared resources Software Information Are provided to computer and other devices on demand, like the electricity grid (C)ANTARA&ANIK 5
- 7. “Microsoft & others are working on quantum computing. It isn’t clear when it will work or become mainstream. There is a chance that within 6-10 years cloud computing will offer super computation by using quantum” - Bill Gates, Founder of Microsoft Corporation "I don't need a hard disk in my computer if I can get to the server faster... carrying around these non-connected computers is byzantine by comparison.“ - Steve Jobs, late chairman of Apple (1997) “With the cloud, individuals and small businesses can snap their fingers and instantly set up enterprise-class services.” - Roy Stephan, Director IT Architecture & Engineering – Intelligent Decisions.

- 9. Public Cloud: • It is offered by third-party providers over the public Internet • available to anyone who wants to use or purchase them. • They may be free or sold on- demand, allowing customers to pay only per usage for the CPU cycles, storage, or bandwidth they consume. EXAMPLES: Amazon Elastic Compute Cloud (EC2), IBM's Blue Cloud, Sun Cloud,Google AppEngine and Windows Azure Services Platform. (C)ANTARA&ANIK 9

(C)ANTARA&ANIK 11
- 12. Cloud Computing Service Delivery Models Infrastructure as a service (IaaS): • provides virtualized computing resources over the internet • cloud provider hosts the infrastructure components traditionally present in an on- premises data center. • It also supplies a range of services to accompany those infrastructure components.(C)ANTARA&ANIK 12
- 13. Cloud Computing Service Delivery Models Platform as a service (PaaS) • third-party provider delivers hardware and software tools • hosts the hardware and software on its own infrastructure. • It frees users from having to install in- house hardware and software to develop or run a new application(C)ANTARA&ANIK 13
- 14. Cloud Computing Service Delivery Models Software as a Service SaaS: • software licensing and delivery mode • software is licensed on a subscription basis and is centrally hosted • sometimes referred to as "on-demand software“ • typically accessed by users using a thin client Examples: Google Apps, Dropbox, ((C)ANTARA&ANIK 14
- 15. ASPECTS Security •Data security in the cloud •Cloud computing standards & compliance •Cloud Governance Cost and Management •Cloud computing pricing and economics •Cloud management and monitoring •Cloud disaster recovery Applications •Software as a service & cloud computing •Mobile cloud computing • Network & applications performance in the cloud(C)ANTARA&ANIK 15
- 18. CONCLUSION • new technologies emerging at a rapid rate • potential of making human’s lives easier • security risks and challenges (C)ANTARA&ANIK 18
