    • 1. Make FreeBSD your choice for a server!
    • 2. Demands for high performance servers <ul><li>Near 100% uptime </li></ul><ul><li>Ease of maintence (virtually or physically) </li></ul><ul><li>Ability to server all users simultaneously </li></ul><ul><li>Ability to upgrade/update with minimal downtime </li></ul>
    • 3. Choices for high performance servers <ul><li>FreeBSD – PC, Alpha and Sun </li></ul><ul><li>Windows NT – PC, MAC and Alapha </li></ul><ul><li>Solaris – PC and Sun </li></ul><ul><li>Linux – PC, Alpha, Sun, MAC </li></ul><ul><li>Novell Netware – PC </li></ul><ul><li>Mac Server - Mac </li></ul>
    • 4. Why choose FreeBSD? <ul><li>Advantages </li></ul><ul><ul><li>Powerful (customization) </li></ul></ul><ul><ul><li>Source code availability </li></ul></ul><ul><ul><li>Server software availability </li></ul></ul><ul><li>Disadvantages </li></ul><ul><ul><li>Arcane and archiac </li></ul></ul><ul><ul><li>Non intuitive </li></ul></ul><ul><ul><li>Limited user software availability </li></ul></ul>
    • 5. Where does FreeBSD come from? <ul><li>Derivitive of original Unix code </li></ul><ul><li>First developed at UC Berkley </li></ul><ul><li>Split off to make a freely developed operating system </li></ul><ul><li>Supported by a community of developers </li></ul><ul><ul><li>Applications </li></ul></ul><ul><ul><li>Networking </li></ul></ul><ul><ul><li>File System (kernel) </li></ul></ul>
    • 6. Design of FreeBSD <ul><li>Bounce buffering </li></ul><ul><li>Merged virtual memory and filesystem buffer cache </li></ul><ul><li>Compatibility modules </li></ul><ul><li>Dynamically loadable kernel modules </li></ul><ul><li>Shared libraries </li></ul><ul><li>SMP (Symetric MultiProcessing) </li></ul>
    • 7. What is FreeBSD? <ul><li>Based on Unix </li></ul><ul><li>Developed in a community </li></ul><ul><li>Mature and dependable </li></ul><ul><li>Multi-platform support </li></ul><ul><li>Wide array of server applications </li></ul><ul><li>Highly configurable </li></ul>
    • 8. Communually developed <ul><li>Anyone can modify the code for their own operating system </li></ul><ul><li>Ideas and thougts are shared and implimented </li></ul><ul><li>Other people update operating system (other than vendor) </li></ul><ul><ul><li>Leads to optimized code </li></ul></ul><ul><ul><li>Knowledge is shared </li></ul></ul>
    • 9. Mature and dependable <ul><li>Can be up for years without downtime </li></ul><ul><li>Applications seperated by kernel </li></ul><ul><li>Used by a number of major internet sites </li></ul><ul><li>SMP (Symetric MultiProcessing) code is the most mature and stable among other server operating system’s </li></ul>
    • 10. Multi-platform support <ul><li>Will run from 386SX to IA64 class PC's </li></ul><ul><ul><li>Supports most disk controllers (IDE, ATAPI, SCSI) </li></ul></ul><ul><ul><li>Supports virtually all network cards </li></ul></ul><ul><ul><li>Will handle almost all back-up devices </li></ul></ul><ul><li>Will run from IPX to Ultra systems by Sun </li></ul><ul><ul><li>Supports most hardware made by Sun Microsystems </li></ul></ul><ul><ul><li>Supports almost hardware made for Sun systems </li></ul></ul><ul><li>Runs on DEC Alpha </li></ul>
    • 11. Wide array of server applications <ul><li>Databases – MySQL, PostgreSQL </li></ul><ul><li>Internet/Intranet </li></ul><ul><ul><li>Share filesystems with NFS </li></ul></ul><ul><ul><li>Distribute network information with NIS </li></ul></ul><ul><ul><li>Support remote logins </li></ul></ul><ul><ul><li>Remote SNMP configuration and management </li></ul></ul><ul><ul><li>Serve files with FTP and SMB </li></ul></ul><ul><ul><li>Resolve Internet hostnames with DNS/BIND </li></ul></ul><ul><ul><li>Routing packets and IP Multicast services </li></ul></ul>
    • 12. Highly configurable <ul><li>Can be customized to suit your needs </li></ul><ul><ul><li>Optimize applications to reach max. efficency </li></ul></ul><ul><ul><li>Maintain and configure all applications remotely </li></ul></ul><ul><ul><li>Update the system without reboots </li></ul></ul><ul><ul><li>Optimize utilities and kernel for your particular processor and hardware </li></ul></ul>
    • 13. Competive Advantages <ul><li>Inexpensive as compared to others </li></ul><ul><li>New updates are released every month </li></ul><ul><li>If something needs to be customized (i.e. kernal), can be done with ease </li></ul><ul><li>Availability over the web </li></ul>
    • 14. Security <ul><li>Kernel support for IP firewall and proxy </li></ul><ul><li>Encryption software </li></ul><ul><ul><li>Kerberos </li></ul></ul><ul><ul><li>PGP </li></ul></ul><ul><li>End-to-end encryption </li></ul><ul><ul><li>Secure Shell </li></ul></ul><ul><ul><li>Virtual Private Network </li></ul></ul>
    • 15. Personal Thoughts <ul><li>Performance is superior to all others </li></ul><ul><li>Very secure alternative to other programs </li></ul><ul><li>Ability to control all internet and intranet services </li></ul><ul><li>Developed almost two decades </li></ul><ul><li>Free! </li></ul>
    • 16. Any questions? <ul><li>All questions can be answered by email: </li></ul><ul><li>[email_address] </li></ul>
