1 Why use Linux Based Server?? How fast is the Internet growing? Web sites (worldwide) are growing from O.5 MM to 7.5 MM from E, which is 45% CAGR. Users (worldwide) are growing at 55% cagr from E to 300MM; growing from 142 million in 1998 to 502 million in Worldwide e-commerce revenues are projected to increase from approximately $50 billion to more than $1.3 trillion during the same period. Source: IDC, July Additionally, according to IDC, spending on Internet information technology infrastructure will grow from approximately $110 billion in 1998 to approximately $592 billion in $592 billion in Is Open Source really penetrating the Web environment? It's dominating! Example 1 - Web Server software (Mar 2000 per Netcraft): 60% Apache 21% MS Internet Information Server (IIS) Example 2 - transfer agents (Feb 2000 Netcraft) Sendmail 80% Why is Linux/open source becoming so popular? In addition to the Internet propelling Linux growth, open source software is essentially free. Its development model ensures that a much larger number of people test it, versus

2 the traditional approach. This larger talent pool drives rapid innovation. Finally, it brings non-proprietary software to customers. Why is Linux better than other operating systems? 1. Linux's demonstrated quality and stability edge 2. The development model taps a worldwide talent pool 3. This same model drives faster innovation 4. Linux frees customers from being tied to vendor agendas 5. It costs less - for 1,000 user system Linux was $11,000 vs. $170,000 for hardware, software, and installation services (the latter of which Linux was higher) 6. Reduced TCO 7. Improved compatibility with other operating systems, applications and networks 8. Ease of customization due to the open availability of the source code Why is Linux well suited for the Internet? 1. Highly reliable 2. Secure 3. Low cost 4. Customizable All of which are essential to the Internet. Where does Linux excel? 1. File and print serving in heterogeneous environments (SAMBA, Nettalk, NFS) 2. Web serving (Apache) 3. and news server (Sendmail, NNTP, list servers) 4. Network infrastructure (DNS/DHCP, LDAP) 5. Network security (Firewalling, IP masquerading, NAT) 6. Inexpensive parallel supercomputing (Beowulf)

3 What is the cost savings associated with Linux? To illustrate, look at Linux vs. NetWare 5 and NT 4.0 for Departmental File/Print Sharing: Number of users: 1,000 NetWare 5 WIN 2000 Linux Software OS license per user $1,195 $4,000 $99 OS per seat client license $54 $128 $0 Total s/w costs $58,780 $144,000 $99 Engineering Engineering time per server (hours) Engineering cost per hour $120 $120 $250 Total engineering costs $1,920 $1,920 $5,500 Hardware # of servers required H/w per unit cost $5,800 $5,800 $5,800 H/w maintenance and support $250 $250 $250 Total h/w costs incl. All servers $23,200 $23,200 $6,050 TOTAL $83,900 $169,120 $16,949 What is driving Linux's growth? 1. It's free - no per-user licensing costs 2. It's widely available - on systems ranging from embedded controllers to roomsized clusters with the performance of supercomputers 3. Stable - continuous uptime of one or more years is not uncommon for Linux installation

4 4. Secure - primarily as a result of open peer review throughout its development 5. Flexible - because source code is available and may be modified to fit customer needs 6. Low risk - because its future development is not dependent upon a single corporation 7. Internet-ready - Linux was designed from the ground up as a network operating system 8. Open - based on published standards and built for interoperability How long has Linux been around? Isn't it new? The first Linux kernel, version 0.02, was released on October 5, It was 71K in size (compressed). In what instances would Windows or Solaris operating systems be better suited? Linux still has some weaknesses: 1. Lack of consistent GUI 2. Lack of scalability past 8 processors 3. Limited support for databases greater than a terabyte in size 4. Virtually no groupware applications 5. Lack of mainstream productivity applications 6. Extreme high-end features (e.g., journaling file systems) in development phase Where is Linux being deployed? What kinds of areas is Linux being used in? 1. Web application development, administration and deployment (e.g., IBM Websphere) 2. Network management (e.g., CA Unicenter) 3. Enterprise applications (e.g., SAP) 4. Custom applications 5. Databases

5 In your opinion, what has to happen to Linux to have it pose a serious threat to NT and other operating systems? The availability of business productivity applications would further boost Linux's adoption. Linux's success is not predicated on the demise of NT or other operating systems. How will the release of the Microsoft's next version of NT affect us? Minimal effect. we expects Linux to co-exist with Windows and continue to grow. How do you determine what advances in the Linux operating systems are advantageous to Primex Technology? Primex Technology actively contributes to the development of the Linux kernel and keep current with Linux advances. New features are continually added to Linux, which means more opportunity. How concerned is Coventive that the development of the Linux operating system might splinter? Has the Coventive seen any fissures in the past? How did it not break off entirely? Not concerned. Linux is held together by the GPL, which prevents proprietary extensions. Why will Linux not go the way of UNIX? Linux is held together by the GPL, which prevents proprietary extensions. UNIX's license permitted proprietary extensions to the code base, and as a result, it splintered. What happens to the Linux community if Linus Torvalds decides tomorrow that Linux has gone the wrong way and he can no longer advocate it's usage? What happens if Linus Torvalds is run over by a bus tomorrow? Who will pick up the responsibility of maintaining the standards of the Linux kernel

6 releases? Linus has been instrumental to the development of the Linux kernel, but a number of people work together to produce the "standard" kernel. Linus actually is the release maintainer for the experimental kernel releases. Alan Cox is the maintainer for the stable, kernel releases, or the "heir apparent" if Linus stopped working on Linux, but it really doesn't matter because it is all open source code. The best code would get into all of the kernel trees and someone would step forward as the maintainer of the tree - no one rules by fiat, either. If they are not doing a good job, then others would step in to replace them. How big is the market opportunity for Linux services? According to IDC preliminary estimates, the services opportunity in the Linux arena will be $8.2 billion by Why is the market for Linux software so strong? Linux is the fundamental force powering the Internet, running on 31% of Internet servers (Windows 95/98/NT has 24%, Solaris/Sun has 17%, BSD 15%, IRIX, 5% as of April 1999, per Internet Operating System Counter). In conjunction, in an open-source world, the value offered to customers shifts from its traditional link in the value chain, i.e. the software product itself, to the need to understand these new technologies and how to build solutions with them. This value shift means that increasingly revenue and profits will come from services. As this shift takes place these benefits will accrue to providers of the best, most in-depth services and support. IDC WW Server Operating System Environment - New Software License Shipments: Platform Shipments Share Shipments Share Growth (%) (%) 1999 (000) (%) Windows NT

7 Linux Netware 3.x, 4.x, 5.0 Combined UNIX Other NOS TOTAL Source: IDC, December 1999 "Linux is the darling SOE for CY99, with shipment growth rate of 93.2% from 1998 to 1999." Share rose from 15.8% in 1998 to 24.6% in Is it a global revolution - or primarily a US one? The IDC numbers above on server shipments are worldwide. Is Linux growing at the expense of Windows NT or UNIX (or both)? Most analysts' opinions are mixed. Clearly, Linux is NOT cannibalizing Windows. About a year ago, Jocelyn surveyed opinion on this from Gartner, IDC, et al and they believed Linux would cannibalize UNIX and OS/2 installed base first and then "potentially" Windows. It is equally likely that Linux adoption is being driven by new deployments of web servers, servers, etc, rather than ripping out Unix or Windows boxes.
