Saving money using Linux starts with the fact that, Linux is open source and thus you do not need to buy a license for it download it for free from the internet and use it as you please. Several of institutions and organization that have moved from licensed operating system to Linux have found that there was a huge reduction in IT costs and user complaints in their organizations. This further led to reduction of labor saving them a lot of money.
To say that Linux will with no doubt aid in saving IT cost we might want to look at the differences that come with Linux as compared to licensed operating systems, amongst them include the benefits, its stability, its compatibility, easy integration, hardware support.
Open source systems have been found to save time on software installations an updates administration saving money within an enterprise by reducing the administration overheads. This has been done by encouraging frequent updates meaning all updates are made available as soon as they are released. An example is Ubuntu that releases updates for free 18 months after the release of new version of the operating system. New releases are done every six months providing a relevant environment for organizations to run their operations always.
Thus unlike licensed products that one has to pay for an update or upgrade Linux updates and upgrades are free of charge. An example one can pay even more than $100 to upgrade windows once new releases are launched, again with the availability of so many types of windows one is likely to over spend in choosing the best since every time you want to change you pay for a license while on the Linux you are free to download and use as it pleases you. Who would not want to take this opportunity?
Another problem with windows arises with malware or viruses. One has to acquire additional antivirus at an added cost to defend against these malicious programs, again the risk of losing data and even the time wastage in the occurrence of these malware is a huge cost a user is likely to incur. For Linux however, you do not need additional software to run to detect or prevent against these malwares as Linux is not a target for the malwares. This leads to reduced cost again.
Another way to look at the cost saving for Linux comes from the side of the applications to be run on the System Software. Unlike off the shelves product for windows that one has to acquire a license for e.g. Microsoft office suit these applications in Linux are free to download and use.
People preferred windows to Linux before because of its Graphical User interface, but today even Linux is utilizing the GUI interface making it easier to be used by every user in the market for an OS.
From many discussions it has been concluded that Linux is the best OS ever to the point of even Bill Gates the founder of Microsoft admitting the same in a conference. If this does not convince you enough I believe you should download your own copy of Linux, installation guides are available all over the internet. Use it for a while and find out if you will not share the same sentiments here. After all experience is the best way to tell.
