Once a configuration management platform is in place, teams have visibility into the work required for configuration tasks. Configuration management work can be identified as dependencies for other work and properly addressed as part of agile sprints. 3) In installing hardware and software, configuration is sometimes the methodical process of defining options that are provided. 1) In computers and computer networks, a configuration often refers to the specific hardware and software details in terms of devices attached, capacity or capability, and exactly what the system is made up of.
Then, solve the same problem of smaller size after deleting bottleneck links. A similar kind of centralized, recursive algorithm is discussed in . Centralized algorithm implies that all information is known at each switch, which is not feasible, hence a distributed algorithm is necessary. At that time it will restart the DHCP process from the beginning by broadcasting a DHCPDISCOVER message. Since its lease has expired, it will accept any IP address offered to it. Once it has a new IP address it will once again be able to use the network.
Why is configuration management important?
Agile software, by definition, reflects the desire to make changes to our software faster so that we can respond to market demands. Configuration management helps us to safely manage our changes and keep velocity high. That hopefully paints a clearer picture of the problems that configuration management is trying to solve. A frequent cause of downtime is bad deployments, which can be caused by differences in running production servers to test servers. With our configuration managed properly, our test environments can mimic production, so there’s less chance of a nasty surprise.

- Improve system recovery after a critical event with automated configuration management.
- When a DHCP client refreshes an assignment, it initially requests the same parameter values, but the DHCP server may assign a new address based on the assignment policies set by administrators.
- Generally, a configuration is the arrangement – or the process of making the arrangement – of the parts that make up a whole.
- Bitbucket offers a powerful system for configuration management that is built around Git pull request workflows and CI/CD pipelines.
- While we need to codify our automation in scripts, if we don’t appropriately track the history of our changes, then we aren’t really achieving configuration management.
The client may also request repeat data for a particular application. For example, browsers use DHCP Inform to obtain web proxy settings via WPAD. The protocol expects the DHCP client to configure its network interface with the negotiated parameters.
Learning Ansible basics
The activity level inherently captures the notion of marking, i.e., when a source is bottlenecked elsewhere, then activity level times the fairshare is the actual fairshare of the bottleneck source. The computation of activity level can be done locally and is an O operation, compared to Ocomputations required in consistent marking definition of configuration . Note the 5-tuplerepresents an instant of the bandwidth sharing problem. When all weights are equal the allocation is equivalent to the general max-min fair allocation as defined in . A simple centralized algorithm for solving the above problem would be to first, find the correct allocation vector for the bottleneck links.
A client can receive DHCP offers from multiple servers, but it will accept only one DHCP offer. Before claiming an IP address, the client will broadcast an ARP request, in order to find if there is another host present in the network with the proposed IP address. If there is no reply, this address does not conflict with that of another host, so it is free to be used.

This configuration tests whether the GW fairness can be achieved in the presence of source bottleneck. When the network reaches steady state the VCShareterm converges toExcessFairshare, achieving generalized fairness criterion. The complexity of the computations done at the switching interval isO. In order for rebinding to work, when the client successfully contacts a backup DHCP server, that server must have accurate information about the client’s binding.
However, since its IP address has changed, any ongoing connections will be broken. An option exists to identify the vendor and functionality of a DHCP client. The information is a variable-length string of characters or octets which has a meaning specified by the vendor of the DHCP client. One method by which a DHCP client can communicate to the server that it is using a certain type of hardware or firmware is to set a value in its DHCP requests called the Vendor Class Identifier . This method allows a DHCP server to differentiate between the two kinds of client machines and process the requests from the two types of modems appropriately.
The first octet is the option code, the second octet is the number of following octets and the remaining octets are code dependent. For example, the DHCP message-type option for an offer would appear as 0x35, 0x01, 0x02, where 0x35 is code 53 for “DHCP message type”, 0x01 means one octet follows and 0x02 is the value of “offer”. An illustration of a typical non-renewing DHCP session; each message may be either a broadcast or a unicast, depending on the DHCP client capabilities. After updates by many subsequent RFCs, it was replaced with RFC 8415, which merged in prefix delegation, and stateless address autoconfiguration. When configuring, many deductions are drawn which are not relevant for describing configurations. Most of the text is configured as fragments of observation and reflection.
On large networks that consist of multiple links, a single DHCP server may service the entire network when aided by DHCP relay agents located on the interconnecting routers. Such agents relay messages between DHCP clients and DHCP servers located on different subnets. Configuration management is a necessary tool for managing complex software systems. Lack of configuration management can cause serious problems with reliability, uptime, and the ability to scale a system. Many current software development tools have configuration management features built in. Bitbucket offers a powerful system for configuration management that is built around Git pull request workflows and CI/CD pipelines.
Dockerfiles are committed to a Git repository for version tracking and need additional configuration management to deploy them to infrastructure. With the advent of plug and play technology, most configurations can be performed automatically in the case of software configurations. The quality of performance and life of the computer or device depends on its configuration. Most important aspects of a configuration are the speed of the processor, speed and stability provided by the motherboard, speed and size of storage, graphical display and software drivers. Some hardware or software applications have certain minimum configuration in order to provide the minimum performance.

Despite their common point of departure, their spatial configurations and handling of the substance differed radically and even conflicted. As will be apparent https://globalcloudteam.com/ in the following, these three possibilities correspond to distinct configurations. A variety of different configurations are possible for these devices.
What is configuration management?
For example, in the case of Windows-based operating systems, on selecting the “Properties” option on “My Computer,” information on the operating system version, processor details and RAM information are provided. The same information about the computer configuration can be obtained through the command “msinfo32” in an MS-DOS prompt. The term is very common in computer science and mathematics, and in scientific and technological fields in general. Thus, for example, two scientists won a 1962 Nobel Prize for their description of the configuration of the DNA molecule.
This removes a potential organizational dependency bottleneck of a software development team waiting for resources from a separate system administration team. In the early years of internet application development, hardware resources and systems administration were primarily performed manually. System administrators wrangled configuration data while manually provisioning and managing hardware resources based on configuration data. During the 1950s the United States Department of Defense developed a technical management discipline to track changes in the development of complex systems. It gave this system and various iterations very technical names, until in 2001 it published a consolidated guidebook that established the technical management system now called configuration management.
Configuration Definition

Small and midsize businesses often practice configuration management to establish and maintain the consistency of a productʻs performance, functionalities, and physical attributes. Configuration management is a subset of IT service management that ensures that the configuration of computer systems, resources, servers, and assets are reliable. This practice is quite important for small businesses, as system issues and failures can result in a delay in business operations and are often quite costly to fix if not well maintained.
It’s not really code so it’s not immediately put in version control and it’s not first-class data so It isn’t stored in a primary database. Traditional and small scale system administration is usually done with a collection of scripts and ad-hoc processes. Configuration data can be overlooked at times, but it is critical to system operation. One team member may tweak a hardware allocation value so that the software runs more efficiently on their personal laptop. When the software is later deployed to a production environment, this new configuration may have a suboptimal effect or may break. Many engineering requirements or considerations can influence the selection of CIs.
