PHP: Formerly Personal Home Page, a language for hobbyists
building Web pages. PHP was recomposed by Andi Gutmans
and Zeev Suraski into PHP 3.0 for professional Web site
builders. It is a dynamic language that runs the latest changes
made in a program without needing to be compiled. It’s used
to link a database to a Web application, for example. It is open

source code and is sometimes referred to as the P in the
open source LAMP stack.

Platform as a service: A cloud platform, such as Salesforce
.com’s Visualforce and Apex, where an application can be de-

veloped that conforms to the platform’s application pattern
and can be run in a cloud that supports the platform, such as
Force.com.

Private cloud: The portion of the enterprise data center that
can be organized around cloud principles, usually a cluster of
x86 servers that are accessible to private company employees
and business partners, who can self-provision virtual ma-
chines. A goal of building a private cloud is often to coordi-
nate activities with a public cloud. Also known as an internal
cloud.

Public cloud: A data server where compute resources are made
available to any member of the public who is willing to pay for
them; Amazon Elastic Cloud Compute (EC2), Microsoft Azure,

and Google App Engine are all examples.

Python: A popular Web site scripting or dynamic language, like
PHP and Perl.
