In order to implement and manage distributed systems, there is a need to use what is known as system management software. Assuming a company is big enough and has operations spread out far enough to warrant a distributed system, the advantages are fairly obvious. For a growing company, there is a cutoff point at which it becomes unrealistic to do individual installations on each station, and sort through the paper and electronic trail left by each user in order to centralize the entire setup.
Once system management is implemented, the process becomes more streamlined. The automation starts offering immediate benefits. It enables reduction in IT staff levels and improves security and information sharing among employees and departments, and with the data already centralized, the reporting and monitoring process becomes a lot easier.
Installation & Management: The biggest benefit is in the form of automation of new installations and upgrades. If a company has 10 computers in the same office space, it's not that hard to do installations individually on each station. But that's out of the question for companies with hundreds or thousands of computers housed at different locations. When a company starts using servers and system management software, the whole process suddenly becomes automated, and needs less staff and less time.
Cost Reduction: There are no ifs and buts as to the cost reduction capabilities, regardless of the size of the company. Even for small companies, the only caveat is whether or not the company is capable of buying system management software and hiring a sys admin. Once these expenses are taken care of, the benefits in the form of lower IT costs are immediate and long lasting.
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 helps enhance security in various ways. For starters, universal settings can be deployed on all stations, and users can be granted access based on their username and job description, regardless of which station they use. It also helps in keeping the system safe from external attacks and hacking.
Critical security updates and software patches can be administered quickly and simultaneously to all stations, thus reducing chances of the system going down or being attacked. Anti-virus software and malware protection can be installed on an enterprise network level, which provides more protection. Centralized data storage and backups on servers offer greater safety and reduce chances of data corruption or data loss due to hardware problems.
Monitoring: Other than automation and cost-reduction, the monitoring capabilities are perhaps the biggest benefit of system management. All the data flowing on the network is automatically centralized, and lends itself to greater monitoring. The network and system can be tweaked to adjust for utilization patterns. User activity monitoring helps management keep track of employees and their work patterns.
To summarize, the immediate advantages of using system management are very much real and the possibilities even bigger. End of the day, each company has to make an informed decision about this based on its own size and growth curve. A cost benefit analysis to figure out the ROI of system management software would be a good place to begin.
