BAPP

The acronym BAPP (or B.A.P.P.) refers to a set of open-source software programs commonly used together to run dynamic web sites or servers:

• BSD, family of operating systems;
• Apache, the web server;
• PostgreSQL, the database management system (or database server);
• Perl, PHP, Python, and/or Primate (mod mono), scripting/programming languages.

The acronym has three major uses:

1. Define a web server infrastructure
2. Define a programming paradigm of developing software
3. Define a software distribution package

To be precise, it is an open source web platform.

As an operating system, FreeBSD (a BSD descendant) is generally regarded as reliable and robust, and of the operating systems that accurately report uptime remotely,^[1] FreeBSD (and other BSD descendants) are the most common free operating system listed in Netcraft's list^[2] of the 50 web servers with the longest uptime (uptime on some operating systems such as some versions of Linux cannot be determined remotely^[1]), making it a top choice among ISPs and hosting providers. A long uptime also indicates that no kernel updates have been deemed necessary, as installing a new kernel requires a reboot and resets the uptime counter of the system.

Though the originators of these open source programs did not design them all to work specifically with each other, the combination has become popular because of its low acquisition cost and because of the ubiquity of its components (which come bundled with most current BSD distributions particularly as deployed by ISPs). When used in combination they represent a solution stack of technologies that support application servers. Other such stacks include unified application development environments such as Apple Computer's WebObjects, Java/Java EE, Grails, and Microsoft's .NET architecture.

The scripting component of the BAPP stack has its origins in the CGI web interfaces that became popular in the early 1990s. This technology allows the user of a web browser to execute a program on the web server, and to thereby receive dynamic as well as static content. Programmers used scripting languages with these programs because of their ability to manipulate text streams easily and efficiently, even when they originate from disparate sources. For this reason system designers often referred to such scripting systems as glue languages.
