DEFINING CLOUD COMPUTING
“Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services.”
“…a hosted infrastructure model that delivers abstracted IT resources over the Internet”
“Cloud computing describes a systems architecture. Period. This particular architecture assumes nothing about the physical location, internal composition or ownership of its component parts.”
IaaS(Infrastructure As a Service)
CLOUD providers offer computers –as physical or more often as virtual machines.
Firewalls,Raw storage,load balancers & Networks.
For wide area connectivity internet can be used.
Cloud users responsible for patching & maintaining the OS & Application software.
Billing is done on a utility computing basis….
SaaS(Software As a Service)
Cloud providers install & operate application software in the cloud.
Cloud users access the software from Cloud Client.
Cloud users don’t manage the Cloud infrastructure & platform.
It has the property of elasticity.
Cloning task onto multiple virtual machine at runtime.
The process is transparent to the cloud users(Single Access Point)..
Cloud “Applications”
SaaS resides here
Most common Cloud / Many providers of different services
Examples: Sales Force, Gmail, Yahoo! Mail, Quicken Online
Advantages: Free, Easy, Consumer Adoption
Disadvantages: Limited functionality, no control or access to underlying technology
