Make FreeBSD your choice for a server

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
  systems

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!
