There are five known definitions for configuration management also known as configuration control in the world of telecommunications and information technology.
The first definition involves a change in firmware, hardware, documentation, test documentation, test fixtures, test and software which are controlled and managed by the automated information system in the context of the whole operation of the system.
The second definition of configuration management is recording and documentation of the changes made from hardware, firmware, and software throughout the lifecycle of the system.
The third definition involves guaranteeing the dependability of the system within the scope of any changes that were made. The aim is to keep the system running so that it has the capability to adapt to changes made so that it keeps on track with the evolution of the product and software. Software configuration management is divided into two areas – the first being the component repository, while the second is engineering support.
The fourth meaning of configuration management covers the ability to promote evaluations through configuration of the computer system to make sure that all areas are functioning properly.
The last definition refers to DQDB Networks, also known as Distributed-Queue Dual-Bus Networks. This ensures that the correct configuration is made by the changes with the help of the function of an external timing source, head bus and default slot generator.
In Configuration Management or CM, we must be aware that there are different types and functions which are subdivided into three categories the Software CM or SCM, the Operational CM or OCM, and the Hardware CM or HCM which are all defined by ITIL®. They may have different functions but all adhere to the same goal of balancing the infrastructure of information technology.
This ITIL report evaluates technologies and applications in terms of their business impact, adoption rate and maturity level to help users decide where and when to invest. The Predictive Analytics Scores below – ordered Read more…
