” The’Cloud’concept is finally wrapping peoples minds around
what is possible when you leverage web-scale infrastructure
(application and physical) in an on-demand way. ’Managed
Services’, ’ASP’, ’Grid Computing’, ’Software as a Service’,
’Platform as a Service’, ’Anything as a Service’ all terms that
couldnt get it done. Call it a ’Cloud’ and everyone goes bonkers.”
- Damon Edwards[7]
”Cloud computing is the user-friendly version of grid computing.”

”Clouds are vast resource pools with on-demand resource allocation. The
degree of on-demandness can vary from phone calls to web forms to actual
APIs that directly requisition servers. I tend to consider slow forms of
requisitioning to be more like traditional datacenters, and the quicker ones to
be more cloudy. A public facing API is a must for true clouds.
Clouds are virtualized. On-demand requisitioning implies the ability to
dynamically resize resource allocation or moving customers from one physical
server to another transparently. This is all difficult or impossible without
virtualization.
Clouds tend to be priced like utilities (hourly, rather than per-resource), and
I think well see this model catching on more and more as computing resources
become as cheap and ubiquitous as water, electricity, and gas (well, maybe not
gas). However, I think this is a trend, not a requirement. You can certainly
have clouds that are priced like pizza, per slice.”

Utility computing merely means ”Pay and Use”, with regards to
computing power.
Utility Computing = Grid Computing + Pay-per-use

Cloud Computing vs ASP [1]
ASP
Cloud Computing is a hot buzzword. There have been other terms
for pretty much the same thing in the past. ASP is certainly one of
those, as is SaaS
Cloud Computing
Two main concepts of cloud computing are that :
it removes the need to maintain physical hardware from the
user, and
the contractual and billing arrangements are almost
completely usage-driven (no fixed costs) and short-term (can
sign-up,ramp-up, cancel at any time)

CloudStack [2] is now owned by Citrix Systems, that allows
building any type of cloud including public,private and hybrid.
Components
It has four main parts :
Compute Nodes (CN),
Pods,
Availability Zones (AZ)
Management Server (MS)

CN
The CNs are hypervisor enabled hosts where the VMs will be
executed.The supported hypervisors are
XenServer,
Oracle VM,
KVM,
VMware vSphere.
Pod
A Pod is a collection of CNs.Virtual machine files are stored in a
Primary Storage(PS) which is defined in a Pod and PS is shared
among the CNs.

AZ
An AZ is a collection of Pods with Secondary Storage, that are
visible to end users who must select one of them to start a VM.
MS
provides web user interface and APIs,
manages the assignment of VM instances to particular hosts,
manages public and private IP addresses to particular
accounts, and
manges the allocation of storage.
