Your A company needs to implement a web server. The first alternative is the Windows IIS and the second is a Linux server with Apache. The company has always used Microsoft products so the system administrators are trained on these products exclusively.

Microsoft Implementation

Product Cost: Windows Web Server 2017 - $469.00 annual license (Internet facing web server only)

Web Server Training: 7-day course - $4795

Support: MS Software assurance, updates and support 25% of license cost annually

Red Hat Linux/Apache Implementation

License Costs: Red Hat Enterprise Linux Standard Subscription - $799 annual license

Training:

Red Hat Linux Systems Administration: 4 days - $2498

Apache and Secure Web Server Administration: 4 days - $2398

Support: Updates and 12 hours x 5 days along with web support included

Three administrators are initially trained for each system. Turnover will result in one additional administrator being trained each year. A course day is 8 hours. The cost of personnel time is $100 per hour.

Assume all costs should be adjusted by an inflation value of 5%. Compare the two alternatives over three years of each implementation using a simple average of the actual cash flows (assume the cost of capital is 0%). What is the most economical web server operating system?
