Need of cloud computing
Cloud Computing is a general term used to describe a new class
of network based computing that takes place over the Internet,
•Cloud computing refers to on demand delivery of it resources
via the internet with pay as you go process.
•Using the Internet for communication and transport provides
hardware, software and networking services to clients
•Cloud computing is a platform as well as a software
application.
Who invented”Cloud computing”??
John McCarthy however opined "computation
may someday be organized as a public
utility”.
Massive development took place in the 90’s.
There is no sole inventor.
Who introduced it??
 Salesforce.com in 1999.
 Delivered enterprise applications via a simple website
 Amazon Web Services in 2002.
 Provided a suite of cloud-based services including storage,
computation and even human intelligence through the
Amazon mechanical trunk
 Amazon Elastic Compute cloud (EC2/S3) (2006) was the first
widely accessible cloud computing infrastructure service.
 Another big milestone came in 2009, as Web 2.0.
How??
On supply and demand basis.
This “supply and demand” stuff is nothing but
“cloud computing”.
Well……,What did they
actually deliver??
 They delivered ….computing to every individual user.
So, what is cloud computing
actually???
Let me explain….
Cloud computing provides the following services
 Infrastructure as a service.
 IAAS
 Platform as a service.
 PAAS
 Software as a service.
 SAAS
Infrastructure as a service (IAAS)
It mainly provides:
 Servers(physical and virtual)
 Storage(data base)
 Maintenance
Provides infrastructure for individuals and companies.
Companies offering IAAS through cloud computing
 Amazon

 Sun
B-hive
Different fields in IAAS
Private hosting
Dedicated
hosting
