Configuration management is a process that includes established methodology, systems, and procedures to control the elements of the change process. Some examples of software configuration metadata are: It’s easy for these configuration values to become an afterthought, leading to the configuration to become disorganized and scattered. Many types of component use electronic sensors to capture data which provides live condition monitoring. Configuration management solves this challenge by creating a “source of truth” with a central location for configuration. This is the first in a series of posts about Drupal 8's configuration management system. This data is analyzed on board or at a remote location by computer to evaluate its current serviceability and increasingly its likely future state using algorithms which predict potential future failures based on previous examples of failure through field experience and modeling. Configuration Management Plan Maintenance The CMP will be updated as per the WBS. CM programs and plans provide technical and administrative direction to the development and implementation of the procedures, functions, services, tools, processes, and resources required to successfully develop and support a complex system. Configuration management (CM) is a systems engineering 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. depend on many different components being serviceable. It needs to be scrubbed from the repositories history or it will be at risk of being exploited. DevOps configuration is the evolution and automation of the systems administration role, bringing automation to infrastructure management and deployment. CI incrementally establishes and maintains the definitive current basis for Configuration Status Accounting (CSA) of a system and its. Configuration Management was introduced as a process in ITIL V2 in 2000, but the principles that underlie the discipline have existed for as long as complex technology systems have been around. An IT asset may represent a piece of software, or a server, or a cluster of servers. All of the options. Ansible, Salt Stack, and Chef are IT automation frameworks. Lack of configuration management can cause serious problems with reliability, uptime, and the ability to scale a system. Construction agencies such as the Federal Highway Administration have used configuration management for their infrastructure projects. Auditing. Alex Pott Drupal Research Engineer Follow July 13, 2015. Many of these functions and models have redefined CM from its traditional holistic approach to technical management. and in ANSI/EIA-649.

Configuration management deals with the state of any given infrastructure or software system at any given time. Bitbucket offers a powerful system for configuration management that is built around Git pull request workflows and CI/CD pipelines. ;login: issue: April 2011, Volume 36, Number 2", "Choosing between the leading open source configuration managers", "NISTIR 7339 Analysis of Standards for Lifecycle Management of Systems for US Army", https://en.wikipedia.org/w/index.php?title=Configuration_management&oldid=1006748625, Articles with specifically marked weasel-worded phrases from July 2016, Creative Commons Attribution-ShareAlike License. Configuration management (CM) for agile development has now been discussed since the turn of the century. This reverse engineering process is wasteful in terms of human and other resources and can be minimized or eliminated using CM. Configuration management can be used to maintain OS configuration files. ISO 20000:1 2011& 2018 Service Management System. 9When Configuration Management principles are applied using effective practices, return on investment is maximized and product life cycle costs are reduced. If not, install Git, initialize a repository for the project, and add the configuration data files to the repository. Each cloud platform has its own representation and interface for common infrastructure components like servers, databases, and queues. The CM process for both hardware- and software-configuration items comprises five distinct disciplines as established in the MIL–HDBK–61A[9] Version Control. During system development, CM allows program management to track requirements throughout the life-cycle through acceptance and operations and maintenance. These new cloud platforms allow teams to specify the hardware resources and network connections they need provisioned through human and machine readable data files like YAML. The following focuses on configuration management as it directly applies to IT software assets and software asset CI/CD. Without version control this can cause problems. When the software is later deployed to a production environment, this new configuration may have a suboptimal effect or may break. Configuration Management principles and practices is a good introduction to the ideas of configuration management. A configuration item is a product (hardware and/or software) that has an end-user purpose. The configuration data files specify a sequence of actions to take to configure a system. Configuration audits are broken into functional and, ANSI/EIA-649-1998 National Consensus Standard for Configuration Management, EIA-649-A 2004 National Consensus Standard for Configuration Management, ANSI EIA-649-C 2019 Configuration Management Standard, GEIA Standard 836–2002 Configuration Management Data Exchange and Interoperability, NATO ACMP 2000 Policy on Configuration Management, NATO ACMP 2100 Configuration Management Contractual Requirements, ITIL Service Asset and Configuration Management. Configuration Management Principles and Practice explains the elements and benefits of a sound CM strategy and shows how to put that strategy into action. This helps build out an audit and accounting system. Configuration audits verify that the system and subsystem configuration documentation complies with the functional and physical performance characteristics before acceptance into an architectural baseline. These attributes are recorded in configuration documentation and baselined. Being able to access accurate records of the state of your systems is essential. It simultaneously maintains the current state of the software (called the “baseline”), while enabling developers to work on new versions for features or fixes. Managing unexpected changes through the use of code review and version control helps to minimize downtime. … [8] Now widely adopted by numerous organizations and agencies, the CM discipline's concepts include systems engineering (SE), Integrated Logistics Support (ILS), Capability Maturity Model Integration (CMMI), ISO 9000, Prince2 project management method, COBIT, ITIL, product lifecycle management, and Application Lifecycle Management. How configuration management helps engineering teams build robust and stable systems. Configuration Management Principles and Practice. Change the password for dev, staging, and production email services. Configuration management deals with the identification, maintenance, reporting on and verification of items and their … The data files are then read and the infrastructure is provisioned in the cloud. Configuration version control enables rollback or “undo” functionality to configuration, which helps avoid unexpected breakage. Through configuration examples and … CM Planning and Management: a formal document and plan to guide the CM program that includes items such as: Administrative meeting guidelines, including a definition of procedures and tools, Configuration control and configuration-status accounting, Configuration Identification (CI): consists of setting and maintaining baselines, which define the system or subsystem architecture, components, and any developments at any point in time. The lack of CM, or its ineffectual implementation, can be very expensive and sometimes can have such catastrophic consequences such as failure of equipment or loss of life. Examples of configuration work are chores and tasks like: Once a configuration management platform is in place, teams have visibility into the work required for configuration tasks. The five disciplines are: The software configuration management (SCM) process is looked upon by practitioners as the best solution to handling changes in software projects. [1][2] Terraform supports Amazon Web Services (AWS), Microsoft Azure, and other cloud platforms. After configuration data has been aggregated and organized a baseline can be established. Configuration Management Schedules Describes the general CM activities schedule . These tools are what will bring enable the automation needed to achieve CI/CD. (ANSI/EIA 649 Rev A) Dockerfiles are committed to a Git repository for version tracking and need additional configuration management to deploy them to infrastructure. Imagine numerous post-it notes with passwords and URLs blowing around an office. [11] Example systems include Ansible, Bcfg2, CFEngine, Chef, Otter, Puppet, Quattor, SaltStack, Terraform, Pulumi and Vagrant. The five CM functions are 1) Configuration Management Planning and Management, 2) Configuration Identification, 3) Configuration Change Management, 4) Configuration Status Accounting and 5) Configuration Verification & Audit. Configuration data can be overlooked at times, but it is critical to system operation. It is an interactive course using syndicate exercises to consolidate learning that discusses roles and responsibilities, key definitions and configuration management processes. These frameworks automate many traditional system administrators' processes. Version control also solves another configuration problem: unexpected breaking changes. principles that are basic for an effective configuration management What are the principle(s) that are basic for an effective configuration management? The SCM process further defines the need to trace changes, and the ability to verify that the final delivered software has all of the planned enhancements that are supposed to be included in the release. This workflow is similar to running ad-hoc shell scripts but offers a more structured and refined experience through the respective platforms ecosystems. When not speaking or coding, you can find Ian indulging his passions in parsers, meta-programming, and domain-specific languages. Configuration data should be aggregated and compiled from ... Baseline. Change management, in contrast, deals with how changes are made to those configurations. These disciplines are carried out[by whom?] Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. Configuration management (CM) is an important, but often neglected, practice that allows application developers and project managers to better identify potential problems, manage changes, and track the … Configuration item (CI) owners: Responsible for the status and attributes of the CI. In the event of suspected problems, the verification of baseline configuration and approved modifications can be quickly determined. Principles of Configuration Management - Part Three. CM verifies that changes are carried out as prescribed and that documentation of items and systems reflects their true configuration. How to implement configuration management. Software configuration management (SCM) is a set of processes, policies, and tools that organizes the development process. 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. The consumers of this data have grown more numerous and complex with the growth of programs offered by original equipment manufacturers (OEMs). c. Binaries should be independent of configuration information. Complex assets such as aircraft, ships, industrial machinery etc. Define roles and responsibilities. In many cases, without CM, the documentation exists but is not consistent with the item itself. Any changes applied to the configuration must be reviewed and accepted by the team. In 1991, the "480 series" was consolidated into a single standard known as the MIL–STD–973 that was then replaced by MIL–HDBK–61 pursuant to a general DoD goal that reduced the number of military standards in favor of industry technical standards supported by standards developing organizations (SDO). The four courses that make up the CM Principles & Implementation (CMPIC) certification program have been developed to provide a solid foundation in Configuration Management (CM) to all those who … CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. The following list of other configuration management tools are designed to be stored in a Git repository and leverage Git version control tracking. At this point configuration data should be organized into data files that can be pointed to as a central source of truth. In the technology world, configuration management is an IT management process that tracks individual configuration items of an IT system. It introduces how configuration management has evolved and is applied within the MOD but looks at the wider applicability of its principles. Configuration change control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. Configuration Management is returned many fold in cost avoidance. Configuration database administrator(s): Responsible for the day-to-day maintenance and updates to the configuration management data bases (CMDBs). This baseline is usually created by reviewing the configuration of a functioning production environment and committing those configuration settings. A perfect example of this process is a GitOps workflow. One team member may tweak a hardware allocation value so that the software runs more efficiently on their personal laptop. Changes to the system are proposed, evaluated, and implemented using a standardized, systematic approach that ensures consistency, and proposed changes are evaluated in terms of their anticipated impact on the entire system. It helps to verify that proposed changes are systematically considered to minimize adverse effects. Today, configuration management is not only used by the defense department, but in software development, IT service management, civil engineering, industrial engineering, and more. These programs can also store information to aid in the maintenance and modification of the infrastructure when it is completed.
