DH Brown Associates [pdf]: A whitepaper entitled, “Migrating Mail and Web Services to Linux.” Here are few advantages Linux has, quoted from the whitepaper:
- License Costs– Depending on what third-party software is required in addition to a Linux distribution, license costs for a Linux web or mail server may be 25 50% of a Windows-based server for similar workloads. The Windows-based server may provide greater functionality, but system administrators and deployment specialists report ieLinux is good enoughli and provides more flexibility for most deployments.
- Remote Management– Linux offers the ability to perform most system administration tasks remotely using standard UNIX/Linux remote login and other remote features. This may save considerable travel time in a campus or metropolitan area and save payroll or service contract dollars in more remote locations.
- Better Uptime– Some users surveyed have experienced higher availability for a single Linux system than Windows NT Server. A typical system administrator or deployment consultant will say that Linux stays up for months whereas Windows NT may need two or three reboots per month. This matches the common wisdom and was borne out by our research.
- Lighter Hardware Requirements– Many of these Linux servers run without the X-Windows system and desktop GUI, which frees up system resources for mail or web serving. Windows cannot be configured similarly.
- Freedom of Choice– Some users do not like being locked into proprietary formats such as Microsoft Active Server Pages for web serving or Exchange. Linux-based solutions offer a choice of mail solution providers and technical support offerings. [via Linux Today]
