If you want to implement and keep control of distributed systems, there is a demand to use what is called system management software. Assuming a firm is big enough and has operations spread out substantially enough to guarantee a distributed system, the extensive benefits are really self evident. For a growing company, there is also a cutoff point at which it becomes unrealistic to do individual installations on each station, and go through the paper and electronic trail left by every user in order to centralize the whole setup.

Virtually all of the companies spend many hours and way too high amounts of assets paying for individuals to manage their infrastructure for them. The advantage of infrastructure management is that there are certainly people there most of the time that are looking out for the network and always ensuring that it is operating at its very best.

This is done remotely so even when the office is closed things can be repaired, slow servers can be noticed and repaired, and when the office reopens in the morning everyone will find that their systems work exactly the way they should, and they are none the wiser of any problems that existed or were repaired the night before.

Cost Reduction: First of all, no company, big or small, needs to worry about not benefiting from system management. The only debatable point is the ROI related to the cost of the software and paying a system administrator. Regardless, once implemented, it cuts down the need for IT staffing and other related expenses on a long-term basis. The real savings come from the capability to install new systems and software faster and at a lower cost. Companies start using client-server architecture, ERP and other kinds of enterprise level software and systems. It helps them expand, and open branches where otherwise it may not have been possible. End of the day, it leads to a massive makeover for the entire company, with large-scale improvements in distribution, productivity, work flow and reporting capabilities.

Security: System management has a huge impact on IT security. The same security settings are implemented on all stations, and any new policies are remotely implemented instantaneously on all the stations. Users can access any station and get the same settings and data, made possible by settings that apply to specific usernames and job or department levels. This makes the network more capable of withstanding external attacks. Security patches and critical updates can be done instantaneously on all stations without any extra effort or manpower, which reduces the window that attackers can use to take advantage of bugs. The network gets centralized enterprise anti virus and malware protection. Even the data is more secure as regards hardware failure or data corruption, since everything is stored on servers with a backup system.

Then there is configuration control, which is the list of methods and approval stages that are needed to modify a configuration point's traits and reinitiate them. Configuration status accounting is the facility needed to document and deal with the configuration baselines correlated to each point at any time period. The last task is Configuration audits, which has two aspects: functional audits and physical audits. The former deals with the functional and performance attributes of the configuration point. On the other hand the latter makes certain that the configuration point is established according to what is required by the detailed design records.


Systems management is a continual process. Even if an effective information system can be created and put into use there is still a good chance that it will need to be modified occasionally to fit the changing environment
