This document summarizes a technical seminar on cloud computing and its applications. The seminar defines cloud computing as manipulating and accessing applications online through data storage, infrastructure, and software provided via the internet. It discusses different types of cloud models (private, public, hybrid, community) and key characteristics of cloud computing including resilience, ubiquitous access, resource pooling, broad network access, rapid elasticity and on-demand self-service. The seminar outlines benefits of cloud computing such as reduced costs, flexibility and scalability. Potential issues discussed include security concerns and dependency on constant internet access.

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.

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

9. VM technology allows multiple virtual
machines to run on a single physical
machine.

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.

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

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:

15.  Lower computer costs
 Improved performance
 Reduced software cost
 Instant software updates
 Improved document format compatibility
 Easier group collaboration
 Device independence

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

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
