PHP is a general-purpose scripting language originally designed for web development to produce dynamic web pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. It also has evolved to include a command-line interface capability and can be used in standalone graphical applications. PHP can be deployed on most web servers and as a standalone interpreter, on almost every operating system and platform free of charge. PHP is installed on more than 20 million websites and 1 million web servers. PHP was originally created by Rasmus Lerdorf in 1995. The main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP as there is no formal specification. PHP is free software released under the PHP License, it is incompatible with the GNU General Public License (GPL) due to restrictions on the usage of the term PHP. While PHP originally stood for "Personal Home Page", it is now said to stand for "PHP: Hypertext Preprocessor", a recursive acronym.

Ruby on Rails was extracted by David Heinemeier Hansson from his work on Basecamp, a project management tool by 37signals (now a web application company). Hansson first released Ruby on Rails as open source in July 2004, but did not share commit rights to the project until February 2005.[9] In August 2006 the framework reached a milestone when Apple announced that it would ship Ruby on Rails with Mac OS X v10.5 "Leopard", which was released in October 2007. Ruby on Rails version 2.3 was released on March 15, 2009. Major new developments in Ruby on Rails include templates, engines, Rack and nested model forms. Templates enable the developer to generate a skeleton application with custom gems and configurations. Engines let one reuse application pieces complete with routes, view paths and models. The Rack web server interface and Metal allow one to write optimized pieces of code that route around ActionController. On December 23, 2008, Merb, another web application framework was launched, and Ruby on Rails announced a commitment to work together. The Ruby on Rails team announced they would work with the Merb project to bring "the best ideas of Merb" into Ruby on Rails 3, ending the "unnecessary duplication" across both communities. Merb was merged with Rails as part of the Rails 3.0 release.

The .NET Framework (pronounced dot net) is a software framework for Microsoft Windows operating systems. It includes a large library, and it supports several programming languages which allows language interoperability (each language can use code written in other languages). The .NET library is available to all the programming languages that .NET supports. The framework's Base Class Library provides user interface, data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. The class library is used by programmers, who combine it with their own code to produce applications. Programs written for the .NET Framework execute in a software (as contrasted to hardware) environment, known as the Common Language Runtime (CLR). The CLR is an application virtual machine so that programmers need not consider the capabilities of the specific CPU that will execute the program. The CLR also provides other important services such as security, memory management, and exception handling. The class library and the CLR together constitute the .NET Framework. The .NET Framework is intended to be used by most new applications created for the Windows platform. To develop new applications, software developers can also use Microsoft's SDK for Windows 7 or .NET Framework 4 (or newer) or Visual Studio 2010 on top of the .NET Framework

Ada is a structured, statically typed, imperative, wide-spectrum, and object-oriented high-level computer programming language, extended from Pascal and other languages. It has strong built-in language support for explicit concurrency, offering tasks, synchronous message passing (via guarded task entries), protected objects (a monitor-like construct with additional guards as in conditional critical regions) and nondeterminism (via select statements).Ada was originally designed by a team led by Jean Ichbiah of CII Honeywell Bull under contract to the United States Department of Defense (DoD) from 1977 to 1983 to supersede the hundreds of programming languages then used by the DoD. Ada is strongly typed and compilers are validated for reliability in mission-critical applications, such as avionics software. Ada is an international standard, the current version (known as Ada 2005) is defined by joint ISO/ANSI standard,combined with major Amendment ISO/IEC 8652:1995/Amd 1:2007.Ada was named after Ada Lovelace (1815–1852), who is often credited as being the first computer programmer.

Amazon Elastic Compute Cloud (EC2) is a central part of Amazon.com's cloud computing platform, Amazon Web Services (AWS). EC2 allows users to rent virtual computers on which to run their own computer applications. EC2 allows scalable deployment of applications by providing a Web service through which a user can boot an Amazon Machine Image to create a virtual machine, which Amazon calls an "instance", containing any software desired.

Amazon SimpleDB is a distributed database written in Erlang by Amazon.com. It is used as a web service in concert with Amazon Elastic Compute Cloud (EC2) and Amazon S3 and is part of Amazon Web Services. It was announced on December 13, 2007.As with EC2 and S3, Amazon charges fees for SimpleDB storage, transfer, and throughput over the Internet. On December 1st 2008, Amazon introduced a new pricing with free tier[3] for 1 GB of data & 25 machine hours. Transfer to other Amazon Web Services is free of charge.

Amazon Relational Database Service or Amazon RDS is a distributed relational database service by Amazon.com. It is a web service running "in the cloud" and provides users a relational database for use in their applications. It was first released on 22 October 2009. Amazon RDS works on lines similar to MySQL, which means that code/infrastructure built on top of MySQL will blend in seamlessly.
