The ability to adjust and customize hardware or software is referred to as “Configurability.” More precisely, it refers to selecting programmable parameters that allow the program to function according to the user’s preferences, putting together desired components for a custom system, and selecting settings in the system’s user-programmable sections. System configuration is a standard SRE operation across the board. However, it can be time-consuming, especially if the engineer is unfamiliar with the configuring system or if the configuration wasn’t created with clarity and usability.
In systems engineering, a system configuration defines the computers, processes, and devices that make up the system. It’s a type of design in which a fixed collection of predefined components can be joined in specified ways, and an assembly of components chosen from this fixed set meets a set of requirements and adheres to a set of constraints.
Whenever software systems are deployed, they are never considered static and unchanging. Systems are continually changing due to changing business needs, infrastructural requirements, and other considerations. A code update will not suffice when we need to modify system behavior rapidly, and a costly, lengthy rebuild and redeployment process is required. Hence, the configuration is described as a human-computer interface that provides a low-cost method of altering system functioning and is typically done in two ways: during initial setup or an emergency reconfiguration.
Humans are in charge of the configuration since humans ultimately administer our systems. The quality of a system’s configuration’s human-computer interface impacts an organization’s ability to run that system reliably. The impact of a well-crafted (or poorly-crafted) configuration interface on system maintainability over time is analogous to the impact of code quality.
Configuration, on the other hand, differs from code in several ways. Changing a system’s capabilities via code is often a time-consuming and labor-intensive procedure that involves modest incremental modifications, code reviews, and testing. Changing a single configuration choice, on the other hand, can have a significant impact on functionality — for example, a faulty firewall configuration rule could lock you out of your system. Second, configuration, unlike code, frequently exists in an untested (or even untestable) environment. Changes to the system setup may be required under duress. A configuration system that can be easily and safely altered during an incident is critical. Consider the early airplane interface design: perplexing controls and indicators resulted in accidents. Operator failures were common, according to research at the time, independent of pilot competence or experience. In computing systems, the relationship between usability and dependability is reflected. Consider what happens if we substitute config files and monitoring graphs for a control stick and dial indications.
Configuration management is a systems engineering technique for aligning a product’s performance, functional, and physical properties with its requirements, design, and operational data throughout its lifecycle. It’s a type of IT service management that assures system resources, computers, servers, and other assets are understood, sound, and trustworthy.
Configuration management is one of the most expensive aspects of provider networks. The enormous complexity of the supported services and infrastructure drives such expenses. Thousands of businesses with varying services and configurations must be seamlessly and reliably connected across vast geographic areas and dynamically growing networks for a primary provider. Furthermore, a single customer’s initial turn-up installation and subsequent maintenance may span multiple businesses and systems inside the supplier. Thus, the stakes for the supported firm are quite high: an outage could result in lost income, delays in “getting to revenue,” inability to meet contractual obligations or disruption of critical organizational activities. Given the magnitude and stakes, it’s remarkable that the most typical configuration management approach entails extensive human labor or ad hoc scripting. The causes for this are numerous.
Every consumer is different in certain aspects from a provider’s standpoint. Although many new installations produced to fulfill service requests have a lot in common, they all reflect unique mixes of services and network configurations. Interactions with customer networks, outdated, missing, incorrect information, and service interactions make both set up and ongoing configuration management operations complicated and error-prone. Furthermore, the network’s devices and the services they serve evolve at a breakneck speed.
Every day, new firmware versions, client needs, and supported applications pop up. Time-to-market for new services is also a critical driver of income, as delays caused by tool configuration, extension, or development can be the difference between profitability and loss. In other words, there is an unmet need in provider networks for solutions that address these complex and even contradicting difficulties when building service configurations.
Technology is likely at the heart of your company. Technology is the product if you sell SaaS (Software-as-a-Service). Even if you don’t, technology is used by every firm to automate its procedures.
The configuration of these systems is crucial to the success of your company. Your systems (servers, networks, operating systems, data centers, configuration files, IT assets, and all other configuration elements) work because of configuration. Therefore, any software that has a settings menu is dealing with configuration management.
To ensure traceability, you must carefully manage it and keep track of configuration changes. Otherwise, your business and end-users may experience system outages, data breaches, and data leaks. Many firms use a configuration management database (CMDB), a configuration management plan, and a configuration manager to ensure successful configuration management and reduce cybersecurity risk.
It’s critical to have accurate records of the state of your systems, and baselining an attribute can help formal configuration change control processes go smoothly. As a result, version control is essential in every IT system. Project management, asset management, audit processes, software development, and debugging are all aided by this. Configuration management also has the following advantages:
Every day, new firmware versions, client requirements, and supported apps emerge. The time-to-market for new services is also a critical driver of revenue, as delays caused by tool configuration, extension, or development can differ between profit and loss. In sum, there is an unmet demand in provider networks for solutions that solve these complex and even contradictory difficulties that arise while creating service configurations.
