Appendix A . ISO 20000:1 2011& 2018 Service Management System. 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. This study yielded results indicating a benefit to using configuration management on projects of this nature. This serviceability is often defined in terms of the amount of usage the component has had since it was new, since fitted, since repaired, the amount of use it has had over its life and several other limiting factors. Most professionals mix up or get confused with Asset management (AM), where it inventories the assets on hand. Configuration management helps engineering teams build robust and stable systems through the use of tools that automatically manage and monitor updates to configuration data. Capturing and disseminating the operating data to the various support organizations is becoming an industry in itself. Automatic processes and procedures when cost effective.

It identifies four procedures that must be defined for each software project to ensure that a sound SCM process is implemented. Configuration management can be used to maintain OS configuration files. I wondered if taking the twenty principles used for an enterprise architecture framework, we could see just how well configuration management stands up to supporting these general architectural principles in an enterprise context. Configuration Verification and Audit: an independent review of hardware and software for the purpose of assessing compliance with established performance requirements, commercial and appropriate military standards, and functional, allocated, and product baselines. Configuration data can be overlooked at times, but it is critical to system operation. Configuration data should be aggregated and compiled from ... Baseline. These tools are what will bring enable the automation needed to achieve CI/CD. Change management and configuration management are complementary, but not identical processes. One team member may tweak a hardware allocation value so that the software runs more efficiently on their personal laptop. The rise of cloud infrastructures has led to the development and adoption of new patterns of infrastructure management. Docker is based on configuration files called Dockerfiles, which contain a list of commands that are evaluated to reconstruct the expected snapshot of operating system state. CM implements the policies, procedures, techniques, and tools that manage, evaluate proposed changes, track the status of changes, and maintain an inventory of system and support documents as the system changes. There is rather much repetition in the book which makes it sometimes little boring to … He has built multi-national teams that value self-direction and self-organization. Configuration values will often be added, removed, or modified.

Imagine numerous post-it notes with passwords and URLs blowing around an office. 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. The Configuration Management process establishes and maintains the consistency of a system’s functional, performance and physical attributes with its requirements, design and operational information and allows technical insight into all levels of the system design throughout the system’s life cycle. Configuration management deals with the state of any given infrastructure or software system at any given time. Configuration Management (CM) is a technical and management discipline, that provides a positive impact on product quality, cost, and schedule when consistently applied. 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. Terraform is an open source configuration management platform by HasiCorp. During system development, CM allows program management to track requirements throughout the life-cycle through acceptance and operations and maintenance. These disciplines are carried out[by whom?] In many cases, without CM, the documentation exists but is not consistent with the item itself. CM verifies that changes are carried out as prescribed and that documentation of items and systems reflects their true configuration. Many types of component use electronic sensors to capture data which provides live condition monitoring. These Guidelines provide the reader with the basic ideas of the industry needs, the benefits to the implementing organization and describes Configuration Management functions and principles… [10] CM for information assurance, sometimes referred to as Secure Configuration Management, relies upon performance, functional, and physical attributes of IT platforms and products and their environments to determine the appropriate security features and assurances that are used to measure a system configuration state. Version control also solves another configuration problem: unexpected breaking changes. Configuration management is a systems engineering process for establishing consistency of a product’s attributes throughout its life. DevOps configuration also brings system administration responsibility under the umbrella of software engineering. release number, data format, role or relationship, held in the Configuration Management database (CMDB). This removes a potential organizational dependency bottleneck of a software development team waiting for resources from a separate system administration team. Any secret data like passwords and keys should be identified and securely encrypted and stored. 9When Configuration Management principles are applied using effective practices, return on investment is maximized and product life cycle costs are reduced. Configuration Management Principles and Practice explains the elements and benefits of a sound CM strategy and shows how to put that strategy into action. 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.[3][4][5]. Without SCM, source code would become so fragmented and unorganized that development would be impossible without breaking major pieces of th… 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. This workflow is similar to running ad-hoc shell scripts but offers a more structured and refined experience through the respective platforms ecosystems. The CM process for both hardware- and software-configuration items comprises five distinct disciplines as established in the MIL–HDBK–61A[9] Configuration management is used to maintain an understanding of the status of complex assets with a view to maintaining the highest level of serviceability for the lowest cost. CI incrementally establishes and maintains the definitive current basis for Configuration Status Accounting (CSA) of a system and its. ;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. Specifically, it aims to ensure that operations are not disrupted due to the asset (or parts of the asset) overrunning limits of planned lifespan or below quality levels. The main purpose of the Configuration Management Working Group (WG) is to ensure that the state of the art and the body of knowledge in CM be used to enhance the state of the art and the body of knowledge of SE; and vice versa.
