What is Information Systems Management
• The ISM program combines the fundamental
intellectual content of both Computer Science
and Business Management Economics.
• An increasingly larger number of companies
and institutions have concluded that their
daily operations have an indispensable
reliance on computer-based systems.
Common Information Management issues
• Large number of disparate systems
• Little integration or coordination between information systems
• No clear strategic direction for the overall technology environment.
• Range of legacy systems requiring upgrading or replacement
• Limited and patchy adoption of existing information systems by staff.
• Poor quality of information, including lack of consistency,
duplication, and out-of-date information.
What is Cloud Computing ?
• a new delivery model for IT services based on the Internet,
• it involves over-the-Internet provision of dynamically scalable &
CC frequently takes the form of web-based tools or applications
that users can access and use through a web browser as if it were a
program installed locally on their own computer.
• Cloud Computing is the fifth generation of computing
(after Mainframe, Personal Computer, Client-Server
Computing, and the web).
What is Cloud Computing ?
1. CC providers deliver common
business applications online that are
accessed from another Web service
or software like a Web browser ,
while the software and data are
stored on servers.
2. The major cloud service providers
include Sales force, Amazon and
Architecture of Cloud Computing
1. The systems architecture of the software
systems involved in the delivery of cloud
computing, typically involves multiple
cloud components communicating with
each other over application programming
interface, usually web services.
2. The two most significant components of
cloud computing architecture are known
as the front end and the back end.
The front end is the part seen by the
client, i.e. the computer user. This includes
the client’s network (or computer) and the
applications used to access the cloud via a
user interface such as a web browser. The
back end of the cloud computing
architecture is the ‘cloud’ itself, comprising
various computers, servers and data
Benefits of Cloud Computing ?
• Provides access to the latest software versions
• Can be accessed from anywhere
• Resiliency and Redundancy
• Improved services
• Environmentally friendly
• Sharing info is not restricted to size
• Innovation & Competitiveness
Why Cloud Computing ?
• Customer Perspective
In one word: economics, minimum TCO(Total Cost of Ownership)
Faster, simpler, cheaper to use cloud applications
No additional capital required for servers and storage
No ongoing operational expenses for running datacenter
Applications can be accessed from anywhere, anytime
• Vendor Perspective
Easier for application vendors to reach new customers
Lowest cost way of delivering and supporting applications
Ability to use commodity server and storage hardware
Ability to drive down data center operational cots
In one word: economics
Downsides Cloud Computing ?
• Immature technologies
• Migrations and customisations
• Data Sovereignty
Industry Examples: Google Docs
Industry Examples: Salesforce CRM

Cloud Computing is the fastest growing part of IT
Tremendous benefits to customers of all sizes
Cloud services are simpler to acquire and scale up or down
Key opportunity for application and infrastructure vendors
Public clouds work great for some but not all applications
Private clouds offer many benefits for internal applications
Public and private clouds can be used in combination
