Software Deployment
Swe04
----++ Description After development, software should be put to use. That is, it should be released and made available to users, who can then download, install, and activate it. These activities are captured under the common term _software deployment_. [[http://www.cs.colorado.edu/~rickhall/][Richard S. Hall]] in the '[[http://www.cs.colorado.edu/~rickhall/deployment/][Software Deployment Information Clearinghouse]]' defines software deployment as follows: "The term software deployment refers to all of the activities that occur after a software system has been developed and made available for release. As such, software deployment includes activities such as packaging, releasing, installing, configuring, updating, and uninstalling a software system." and "Software deployment is the assembly and maintenance of the resources necessary to use a version of a system at a particular site." The following deployment activities make up the software deployment _process_: * Release * Packaging * Transfer * Installation * Configuration * Activation * De-activation * Update * Adapt * De-installation * De-release These activities are not necessarily performed sequentially. Many phases of the deployment process are often performed manually. For example, downloading, building and installing a source distribution of a software package, requires a number of commands to be formulated and executed. Each such command requires knowledge of some sort about the activity. Manual deployment does not scale when deploying * many applications * applications composed from seperately deployed components * on multiple machines * on different types of machines ----++ Tools Many tools are available supporting one or more deployment activities. Here is a list with representative tools, classified by the main activity the tool supports. ----+++ Release * [[http://sourcewell.berlios.de/html/][SourceWell]] -- software announcement & retrieval ----+++ Configuration * [[GNU build tools]] (autoconf, automake, libtool) -- generation of scripts to adapt a source tree to a consumer site before compilation ----+++ Packaging * [[RedHat Package Manager]] -- packaging, installing, de-installing, updating of binary distributions for the RedHat Linux operating system * [[http://www.easysw.com/epm/][EPM - ESP Package Manager]] * FileWave * SmartUpdate (Netscape) * [[http://www.program-transformation.org/Tools/AutoBundle][AutoBundle]] -- bundling of source packages and package announcement through [[http://www.program-transformation.org][package base]] * [[http://www.cryon.com/gbuild/][gbuild]] -- a script written to simplify package maintenance ----+++ Installation & Update * [[FreeBSD ports collection]] -- automatic installation and updates based on _source code_ distributions * [[http://www.autorpm.org/][autorpm]] -- automatic update to newly available rpms * up2date -- automatic update of rpms ----+++ Activation ----+++ Integrated deployment tools * [[http://www.ximian.com/products/redcarpet/][Red Carpet]] -- proposes software updates based on analysis of consumer site and announcements from producer * [[Software Dock]] ----+++ Other Tool Collections * [[http://www.cs.colorado.edu/~rickhall/deployment/links.html][Software Deployment Links]] at the [[http://www.cs.colorado.edu/~rickhall/deployment/][Software Deployment Information Clearinghouse]] ----++ Issues * Managing an installation * Library versions: multiple, dependency * Adaptability to configuration * Traceability and predictability * Obfuscation -------------------------------++ Literature * [[http://www.tldp.org/HOWTO/Software-Release-Practice-HOWTO/][Software Release Practice HOWTO]] by Eric S.
