Software ConfigurationManagement (SCM)
“the discipline of identifying the configuration ofa system at distinct points in time for the purposeof systematically controlling changes to theconfiguration and maintaining the integrity andtraceability of the configuration throughout thesystem life cycle.” SWEBOK v3 (Ch. 6)
“Software configuration management (SCM) is asupporting-software life cycle process that benefitsproject management, development andmaintenance activities, quality assurance activities,as well as the customers and users of the endproduct.” SWEBOK v3 (Ch. 6)
Examples
Fundamental Features Manage changes to files over time Track changes, provide history, auditing, tracing Provide mechanisms to maintain versions Allow going backward and forward in time, recoverolder versions
More than just Version Control Version (revision) control of: source code, documentation,configuration files, Workflow management: branch, merge, pull requests, tagging File access: distributed, centralized, permissions Manage/facilitate concurrent access: merge model or locking Record who made changes, blame See: https://en.wikipedia.org/wiki/Comparison of version control software
Really, more than justVersion Controlis the primary enabler of many core SE activities Build: build automation, release management Test: test automation, code coverage, traceability Documentation: doc generation Requirements/Specifications Modeling: modeling artifacts Changes: change management Maintenance: defect tracking, bugs, tickets ?

Docker“Docker containers wrap up a piece of software in a complete filesystem thatcontains everything it needs to run: code, runtime, system tools, system libraries– anything you can install on a server. This guarantees that it will always run thesame, regardless of the environment it is running in.” docker build -t lab6image . docker run -it lab6image /bin/bash docker run -d -p 80:80 —name webserver nginxImages: https://www.docker.com
