update: Update the files in a working copy with the latest version from a repository; lock: Lock files in a repository from being changed by other users; add: Mark specified files to be added to repository at next commit; remove: Mark specified files to be removed at next commit (note: keeps cohesive revision history of before and at the remove.)
Source Code Control System (SCCS) [open, shared] – part of UNIX; based on interleaved deltas, can construct versions as arbitrary sets of revisions; extracting an arbitrary version takes essentially the same time and is thus more useful in environments that rely heavily on branching and merging with multiple "current" and identical versions
This is an accepted version of this page This is the latest accepted revision, reviewed on 25 February 2025. Integration of software development and operations DevOps is the integration and automation of the software development and information technology operations [a]. DevOps encompasses necessary tasks of software development and can lead to shortening development time and improving the ...
Generally thought of as an extension of infrastructure as code (IaC) frameworks. [1] CCA tools include Ansible, Chef software, Otter, Puppet (software), Rudder (software) and SaltStack. [5] Each tool has a different method of interacting with the system some are agent-based, push or pull, through an interactive UI.
For the duration of an orchestration task, a process running the module communicates with the controlling machine with a JSON-based protocol via its standard input and output. [18] When Ansible is not managing a node, it does not consume resources on the node because no daemons are run or software installed. [17]
CI/CD bridges the gaps between development and operation activities and teams by enforcing automation in building, testing and deployment of applications. CI/CD services compile the incremental code changes made by developers, then link and package them into software deliverables. [3]
The rules a compiler applies to the source creates implicit standards. For example, Python code is much more consistently indented than, say Perl, because whitespace (indentation) is actually significant to the interpreter. Python does not use the brace syntax Perl uses to delimit functions. Changes in indentation serve as the delimiters.
StackStorm (abbreviation: ST2) is an open source event-driven platform for runbook automation. It supports the Infrastructure as Code (IaC) approach to DevOps automation and has been compared with SaltStack and Ansible, [2] it primarily focuses on doing things or running workflows based on events.
