ranging effects across IT,
Information Architecture,
Business, Software Engineering,
and Data Storage
Cloud computing refers to the
delivery of computing resources
over the Internet.

5. Why cloudcomputing ???...
Cloud computing is user-centric
 Cloud computing is task-centric

6. HISTORY
Concept evolved in 1950 (IBM) called RJE (Remote Job Entry
process)
In 2006 Amazon provided first public cloud AWS (Amazon Web

cloud.
Three types of clients
i. Mobile
ii. Thick
iii. Thin( most popular)

9. DISTRIBUTED SERVERS
Often servers are in
geographically in different
places, but server acts if they are
working next to each other

10. Data center
It is collection of servers
where application is
placed and is accessed via
internet

11. Service models
