Scalability

Security

ROI (Return On Investment)

TCO (Total Cost of Ownership)

Reliability

You can easily manage the necessary workloads in today’s

business environment

Linux machine can do as FTP server, Web server, Mail

server, DHCP server, DNS server, …and run smoothly

You do NOT need to reboot machine after installing new

softwares or services

Scalability

The release of the 2.4 kernel can handle large business

workloads that once could only be addressed by closed,

proprietary platforms and solutions

Security

The open source model allows for auditing policy

When problems are found, fixes are developed and tested

by the group of worldwide programmers

Viruses are almost non-existent on Linux

ROI (Return On Investment)

The open source licensing model allows for no per unit fees

or licensing charges.

This will significantly reduce IT infrastructure expense

TCO (Total Cost of Ownership)

Each Linux administrator can maintain a large number of

servers and clients. This reduces the total cost of ownership of

Linux versus Windows, Netware and other PC platforms
