FreeBSD is an open source, Unix-like operating system that is highly customizable, secure, and stable. It provides high performance for servers with near 100% uptime and minimal downtime for upgrades. FreeBSD has a large community of developers contributing to its mature codebase and wide range of server applications. It is a free alternative to proprietary operating systems that supports hardware from many vendors.

1. Make FreeBSD your choice for a server!

2. Demands for high performance servers Near 100% uptime Ease of maintence (virtually or physically) Ability to server all users simultaneously Ability to upgrade/update with minimal downtime

3. Choices for high performance servers FreeBSD – PC, Alpha and Sun Windows NT – PC, MAC and Alapha Solaris – PC and Sun Linux – PC, Alpha, Sun, MAC Novell Netware – PC Mac Server - Mac

4. Why choose FreeBSD? Advantages Powerful (customization) Source code availability Server software availability Disadvantages Arcane and archiac Non intuitive Limited user software availability

5. Where does FreeBSD come from? Derivitive of original Unix code First developed at UC Berkley Split off to make a freely developed operating system Supported by a community of developers Applications Networking File System (kernel)

6. Design of FreeBSD Bounce buffering Merged virtual memory and filesystem buffer cache Compatibility modules Dynamically loadable kernel modules Shared libraries SMP (Symetric MultiProcessing)

7. What is FreeBSD? Based on Unix Developed in a community Mature and dependable Multi-platform support Wide array of server applications Highly configurable

8. Communually developed Anyone can modify the code for their own operating system Ideas and thougts are shared and implimented Other people update operating system (other than vendor) Leads to optimized code Knowledge is shared

9. Mature and dependable Can be up for years without downtime Applications seperated by kernel Used by a number of major internet sites SMP (Symetric MultiProcessing) code is the most mature and stable among other server operating system’s

10. Multi-platform support Will run from 386SX to IA64 class PC's Supports most disk controllers (IDE, ATAPI, SCSI) Supports virtually all network cards Will handle almost all back-up devices Will run from IPX to Ultra systems by Sun Supports most hardware made by Sun Microsystems Supports almost hardware made for Sun systems Runs on DEC Alpha

11. Wide array of server applications Databases – MySQL, PostgreSQL Internet/Intranet Share filesystems with NFS Distribute network information with NIS Support remote logins Remote SNMP configuration and management Serve files with FTP and SMB Resolve Internet hostnames with DNS/BIND Routing packets and IP Multicast services

12. Highly configurable Can be customized to suit your needs Optimize applications to reach max. efficency Maintain and configure all applications remotely Update the system without reboots Optimize utilities and kernel for your particular processor and hardware

13. Competive Advantages Inexpensive as compared to others New updates are released every month If something needs to be customized (i.e. kernal), can be done with ease Availability over the web

14. Security Kernel support for IP firewall and proxy Encryption software Kerberos PGP End-to-end encryption Secure Shell Virtual Private Network

15. Personal Thoughts Performance is superior to all others Very secure alternative to other programs Ability to control all internet and intranet services Developed almost two decades Free!
