What is Cloud Computing ??Cloud computing is about delivering
computing resources (Hardware and Software) as on-demand service or
virtual infrastructure to clients over the Network. "Cloud
computing is a model for enabling convenient, on-demand network
access to a shared pool of configurable computing resources (e.g.,
networks, servers, storage, applications, and services) that can be
rapidly provisioned and released with minimal management effort or
service provider interaction."

no system administration. Increasing resources doesnt compensate
for bad architecture of your system/application. Still
configuration and versioning issues with large cluster of machines.
Performance and Scaling are more than problems with resources
Applications/Systems migration is not just a click away

front end and a back end. They are connected through a network
Front End The front end is the kind of user interface by which the
user interacts with the system. The front end is composed of a
client computer, or the computer network of an enterprise, or the
applications used to access the cloud. Back End The back end is the
cloud itself The back end provides the applications, computers,
servers, and data storage that creates the cloud of services.

physical assets Virtual machine, servers, network devices, storage
disks, etc. We have control of the operating systems, storage,
deployment applications, and, to a limited degree, control over
select networking components. Service providers offers capacity for
rent, basically hosted Data Centers & Servers Example Print On
Demand (POD) The POD model is based on the selling of customizable
products. PODs allow individuals to open shops and sell designs on
products. With cloud storage capabilities, a POD can provide
unlimited storage space.

programming language execution environment, database and web server
It provides a way to deploy applications to the cloud using
programming languages and tools supported by the provider. Platform
as a Service (PaaS) provides access to operating systems and
associated services. Example PaaS has providers such as Amazon's
Elastic Compute Cloud (EC2), Google App Engine Application
developers can develop and run their software solutions on a cloud
platform without the cost and complexity of buying and managing the
underlying hardware and software layers.

provided on demand to users. Example Software as a Service (SaaS)
has providers such as Google Pack. Google Pack includes Internet
accessible applications, tools such as Calendar, Gmail, Google
Talk, Docs, and many more. Social Networking Websites (Facebook,
Twitter, soundcloud)

The information contained herein is subject to change without

public or a large industry group and are owned and provisioned by
an organization selling cloud services. i.e. Amazon Private clouds
exist within your company's firewall and are managed by your
organization. They are cloud services you create and control within
your enterprise. Private clouds offer many of the same benefits as
the public clouds the major distinction being that your
organization is in charge of setting up and maintaining the cloud.
Hybrid clouds are a combination of the public and the private cloud
using services that are in both the public and private space.
Management responsibilities are divided between the public
cloud
