- 2. DEPARTMENT OF ELECTRONICS AND COMMUNICATION ENGINEERING TECHNICAL SEMINAR ON “ CLOUD COMPUTING AND ITS APPLICATIONS” PRESENTED BY RUDRO JYOTI BISWAS (1EW12EC081) 2
- 3. Cloud- The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is present at remote location. Cloud can provide services over network, i.e., on public networks or on private networks, i.e., WAN, LAN or VPN. Applications such as e-mail, web conferencing, customer- relationship management (CRM),all run in cloud. • Cloud Computing - Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure and application. 3

- 8. • Benefits of Virtual Machines Virtualization help making efficient use of hardware resources Facilitates a greater degree of abstraction Easily move from one piece of hardware to another Replicate them at will Create more scalable and flexible infrastructure Snapshots • Cloud computing has taken that degree of efficiency and agility realized from virtualization Pooled resources Geographic diversity Universal connectivity 8
- 9. VM technology allows multiple virtual machines to run on a single physical machine. 9 Hardware Virtual Machine Monitor (VMM) / Hypervisor Guest OS (Linux) Guest OS (NetBSD) Guest OS (Windows) VM VM VM AppApp AppAppApp Xen VMWare UML Denali etc. Performance: Para-virtualization (e.g. Xen) is very close to raw physical performance!
- 10. Cloud computing enables companies and applications, which are system infrastructure dependent, to be infrastructure-less. By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment! Clients can: Put their data on the platform instead of on their own desktop PCs and/or on their own servers. They can put their applications on the cloud and use the servers within the cloud to do processing and data manipulations etc. 10

- 12. Several large Web companies are now exploiting the fact that they have data storage capacity that can be hired out to others. • allows data stored remotely to be temporarily cached on desktop computers, mobile phones or other Internet-linked devices. Amazon’s Elastic Compute Cloud (EC2) and Simple Storage Solution (S3) are well known examples • Mechanical Turk 12
- 13. The use of the cloud provides a number of opportunities: It enables services to be used without any understanding of their infrastructure. Cloud computing works using economies of scale: Data and services are stored remotely but accessible from “anywhere”. In parallel there has been backlash against cloud computing Security could prove to be a big issue: 13
- 14. Amazon EC2 and S3 Services Google App-Engin Windows Azure Cloud Computing Application in Indian context I) E-Governance II) Rural development 14
- 15. Lower computer costs Improved performance Reduced software cost Instant software updates Improved document format compatibility Easier group collaboration Device independence 15
- 16. Requires a constant Internet connection Does not work well with low speed connection Features might be limited Can be slow Storage data might not be secure Stored data can be lost General concerns 16
- 17. 1. More application availability on the cloud 2. Increased growth in the market for cloud 3. More hybrid cloud adoption 4. Increased development for the cloud 5. More innovation because of cloud 17
