WHAT IS OPEN SOURCE

Open source doesn't just mean access to the source code. The distribution
terms of open
-
source software must comply with the following criteria:

1. Free Redistribution

The license shall not restrict any party from selling or giving away the software
as a component of an aggregate software distribution containing programs
from several different sources.

2. Source Code

The program must include source code
, and must allow distribution in source
code as well as compiled form. Where some form of a product is not distributed
with source code, there must be a well
-
publicized means of obtaining the
source code for no more than a reasonable reproduction cost preferably,
downloading via the Internet without charge.

3. Derived Works

The license must allow modifications
and derived works, and must allow them
to be distributed under the same terms as the license of the original software.



Source:
http://www.opensource.org/docs/osd

WHAT IS OPEN SOURCE

4. Integrity of The Author's Source Code

The license may restrict source
-
code from being distributed in modified form
only if the license allows the distribution of "patch files"
with the source code for
the purpose of modifying the program at build time. The license must explicitly
permit distribution of software built from modified source code. The license may
require derived works to carry a different name or version number from the
original software.


5. No Discrimination Against Persons or Groups

The license must
not discriminate against any person or group of pers
ons
.


6. No Discrimination Against Fields of Endeavor

The license must not restrict anyone from making use of the program in a
specific field of endeavor. For example,
it may not restrict the program from
being used in a business, or from being used for genetic research
.



Source:
http://www.opensource.org/docs/osd

WHAT IS OPEN SOURCE

7. Distribution of License

The rights attached to the program must apply to all to whom the
program is redistributed
without the need for execution of an additional
license by those parties.

8. License Must Not Be Specific to a Product

The rights attached to the program must not depend on the program's
being part of a particular software distribution.

9. License Must Not Restrict Other Software

The license must not place restrictions on other software that is
distributed along with the licensed software.
For example, the license
must not insist that all other programs distributed on the same medium
must be open
-
source software.

CLASSIFICATION OF CLOUD COMPUTING:

According to National Institute of Standard and Technology (U.S.
Department of Commerce),

Software as a Service (
SaaS
):

Through this service, educational
institutions can subscribe for Web based application software and pay
for usage of the software.

Infrastructure as a service (
IaaS
):
Through this service, educational
institutions can subscribe for a virtual IT infrastructure that consists of
servers, networks, data storage and other necessary tools properly
configured to form a virtual computing environment.

Platform as a service (
PaaS
):
Through this service, educational
institutions can subscribe for a Web based application development
platform to design, develop, test, deploy, upgrade, and host Web based
application software. It allows the developers of the software to form a
community for the collaboration on a project.

services offered by, a provider. This is a
strong driver for cloud providers to
improve security practices.
