Capistrano (software)
Capistrano is an open-source tool for running scripts on multiple servers; its main use is deploying web applications. It automates the process of making a new version of an application available on one or more web servers, including supporting tasks such as changing databases. Capistrano is written in the Ruby language and is distributed using the RubyGems distribution channel. It is an outgrowth of the Ruby on Rails web application framework, but it is also used to deploy web applications written using other languages, for example, PHP. Capistrano is implemented primarily for use on the UNIX shell command line. A user may choose from many Capistrano recipes, e.g. to deploy current changes to the web application or roll back to the previous deployment state. Originally called SwitchTower, the name was changed to Capistrano in March 2006 due to a trademark conflict. The original author, Jamis Buck, announced on February 24, 2009 that he is no longer the maintainer of the proje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby (programming Language)
Ruby is an interpreted, high-level, general-purpose programming language which supports multiple programming paradigms. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. It was developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. Ruby is dynamically typed and uses garbage collection and just-in-time compilation. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. According to the creator, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, BASIC, Java and Lisp. History Early concept Matsumoto has said that Ruby was conceived in 1993. In a 1999 post to the ''ruby-talk'' mailing list, he describes some of his early ideas about the language: Matsumoto describes the design of Ruby as being like a simple Lisp language at its core, with an object system like that of Smalltalk, blocks inspired by higher-o ...

Rake (software)
Rake is a software task management and build automation tool created by Jim Weirich. It allows the user to specify tasks and describe dependencies as well as to group tasks in a namespace. It is similar in to SCons and Make. It's written in the Ruby programming language and the Rakefiles (equivalent of Makefiles in Make) use Ruby syntax. Rake uses Ruby's anonymous function blocks to define various tasks, allowing the use of Ruby syntax. It has a library of common tasks: for example, functions to do common file-manipulation tasks and a library to remove compiled files (the "clean" task). Like Make, Rake can also synthesize tasks based on patterns: for example, automatically building a file compilation task based on filename patterns. Rake is now part of the standard library of Ruby from version 1.9 onward. Example Below is an example of a simple Rake script to build a C Hello World program. file 'hello.o' => 'hello.c' do sh 'cc -c -o hello.o hello.c' end file 'hello' => 'hell ...

Configuration Management
Configuration management (CM) is a process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings. Introduction CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle. The CM process facilita ...

Comparison Of Open Source Configuration Management Software
This is a comparison of notable free and open-source configuration management software, suitable for tasks like server configuration, orchestration and infrastructure as code typically performed by a system administrator. Basic properties "Verify mode" refers to having an ability to determine whether a node is conformant with a guarantee of not modifying it, and typically involves the exclusive use of an internal language supporting read-only mode for all potentially system-modifying operations. " Mutual auth" refers to the client verifying the server and vice versa. "Agent" describes whether additional software daemons are required. Depending on the management software these agents are usually deployed on the target system or on one or many central "controller" servers. Although "Agent-less" = "No" is colored red and might seem to be a negative, in fact having an agent can be considered quite advantageous to many. Consider the impact if an agent-less tool loses connectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puppet (software)
In computing, Puppet is a software configuration management tool which includes its own declarative language to describe system configuration. It is a model-driven solution that requires limited programming knowledge to use. Puppet is produced by Puppet Inc., founded by Luke Kanies in 2005. Its primary product, Puppet Enterprise, is a proprietary and closed-source version of its open-source Puppet software. They use Puppet's declarative language to manage stages of the IT infrastructure lifecycle, including the provisioning, patching, configuration, and management of operating system and application components in data centers and cloud infrastructures. Puppet uses an open-core model; its free-software version was released under version 2 of the GNU General Public License (GPL) until version 2.7.0, and later releases use the Apache License, while Puppet Enterprise uses a proprietary license. Puppet and Puppet Enterprise operate on multiple Unix-like systems (including Linux, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt (software)
Salt (sometimes referred to as SaltStack) is a Python-based, open-source software for event-driven IT automation, remote task execution, and configuration management. Supporting the "infrastructure as code" approach to data center system and network deployment and management, configuration automation, SecOps orchestration, vulnerability remediation, and hybrid cloud control. History Salt originated from the need for high-speed data collection and task execution for data center systems administrators managing massive infrastructure scale and resulting complexity. The author of Salt, Thomas S. Hatch, had previously created several utilities for IT teams to solve the problem of systems management at scale, but found these and other open source solutions to be lacking. Hatch decided to use the ZeroMQ messaging library to facilitate the high-speed requirements and built Salt using ZeroMQ for all networking layers. In late May 2011 initial progress was made toward the delivery of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chef (software)
Progress Chef (formerly Chef) is a configuration management tool written in Ruby and Erlang. It uses a pure-Ruby, domain-specific language (DSL) for writing system configuration "recipes". Chef is used to streamline the task of configuring and maintaining a company's servers, and can integrate with cloud-based platforms such as Amazon EC2, Google Cloud Platform, Oracle Cloud, OpenStack, IBM Cloud, Microsoft Azure, and Rackspace to automatically provision and configure new machines. Chef contains solutions for both small and large scale systems. Features The user writes "recipes" that describe how Chef manages server applications and utilities (such as Apache HTTP Server, MySQL, or Hadoop) and how they are to be configured. These recipes (which can be grouped together as a "cookbook" for easier management) describe a series of resources that should be in a particular state: packages that should be installed, services that should be running, or files that should be written.

Ansible (software)
Ansible is a suite of software tools that enables infrastructure as code. It is open-source and the suite includes software provisioning, configuration management, and application deployment functionality. Originally written by Michael DeHaan and acquired by Red Hat in 2015, Ansible is designed to configure both Unix-like systems and Microsoft Windows. Ansible is agentless, relying on temporary remote connections via SSH or Windows Remote Management which allows PowerShell execution. The Ansible control node runs on most Unix-like systems that are able to run Python, including Windows with Windows Subsystem for Linux installed. System configuration is defined in part by using its own declarative language. History The term "ansible" was coined by Ursula K. Le Guin in her 1966 novel ''Rocannon's World'', and refers to fictional instantaneous communication systems. The Ansible tool was developed by Michael DeHaan, the author of the provisioning server application Cobbler and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domain-specific Programming Language
A domain-specific language (DSL) is a computer language specialized to a particular application domain. This is in contrast to a general-purpose language (GPL), which is broadly applicable across domains. There are a wide variety of DSLs, ranging from widely used languages for common domains, such as HTML for web pages, down to languages used by only one or a few pieces of software, such as MUSH soft code. DSLs can be further subdivided by the kind of language, and include domain-specific ''markup'' languages, domain-specific ''modeling'' languages (more generally, specification languages), and domain-specific ''programming'' languages. Special-purpose computer languages have always existed in the computer age, but the term "domain-specific language" has become more popular due to the rise of domain-specific modeling. Simpler DSLs, particularly ones used by a single application, are sometimes informally called mini-languages. The line between general-purpose languages and domai ...
