10 False Reasons for using LINUX Or “Beware of Jumping on the Bandwagon” Dennis Adams 1 March 2000 © Dennis Adams Associates
Why I am doing this Presentation • Warn Management of being dragged into technical decisions – By “Techies” • Who Love Technology – Particularly if they can get to Play with it ! • Speaking as a Techie Myself. • Magazines etc. have identified “Good Reasons” for moving to Linux…. 2 March 2000 © Dennis Adams Associates
1: It’s not Microsoft • Not really a valid reason to purchase software • You may not like Bill Gates / Microsoft etc. – But is that (in itself) justification for Linux ? • The anti-Microsoft camp speaks about software quality. – The only valid reason for purchasing software is the business benefit 3 March 2000 © Dennis Adams Associates
2: It’s Open Source • So anyone can alter it. . • Which destroys standardisation ! • Are you really intending to read the source ? – No ! • Then why the interest in Open Source. . ? – Yes ! • Haven’t you got anything interesting to do. . ? 4 March 2000 © Dennis Adams Associates
3: Support is available from anyone on the Web • Do you really want someone who. . – You don’t know – has no real interest in your company – has no financial return for doing a good job – has no liability for bad workmanship – probably has no Q/A or Quality Control supervising his work • Supporting Your Business ? 5 March 2000 © Dennis Adams Associates
4: It’s available from multiple suppliers • Each supplier has their own distribution • Distributions differ between vendors • Software Houses certify their products for a particular version of a given vendor’s product. • Sounds like the early days of UNIX ? 6 March 2000 © Dennis Adams Associates
5: It’s cheap to buy and use • Cost of Operating System Software is only a small percentage of the total. • Have you worked out the cost of supporting it ? – Often more than purchase costs 7 March 2000 © Dennis Adams Associates
6: There is a standard reference version • In fact, there are several. • Like Unix • And they change all the time – New versions of the Linux Kernel come out every few months. 8 March 2000 © Dennis Adams Associates
7: Upgrades and Enhancements are very frequent. • Which is not very helpful if you are trying to have a standard, supportable infrastructure for production deployment of missioncritical applications. • It’s bad enough with HP/UX version 10. 20, 11. 0 i, 12. 0 with Sybase 11. 5. 11. 9. 2, 11. 9. 3, 12. 0. 1 etc. . 9 March 2000 © Dennis Adams Associates
8: It scales over anything from a 386 to S/380 • So ? • Great idea for software houses to develop S/380 software using a 386 • Do you really anticipate such a breadth of compute power range ? • And is it really as efficient on each possible type of hardware platform ? • In fact, it lives best on Intel Pentium 10 March 2000 © Dennis Adams Associates
9: It is immune to Viruses • Are You Sure ? • Certain ? • Sounds like a challenge to me ! 11 March 2000 © Dennis Adams Associates
10: It can Emulate NT, 98, Atari etc. • True ! • The best emulator for NT is probably – NT. • (Although some benchmarks suggest that Linux Emulators are faster than native NT !) 12 March 2000 © Dennis Adams Associates
11: Millions of Apache users can’t all be wrong • Sounds familiar ? – Millions of Microsoft Office users can’t all be wrong • Can they ? ? ? • How do you get Competitive Advantage by using exactly the same solution as your competitors ? 13 March 2000 © Dennis Adams Associates
Conclusions • Beware of Bandwagons • Make Decisions for Business Reasons • Linux probably has a place in your organisation – But it’s your decision • Not your techies’ decision. 14 March 2000 © Dennis Adams Associates
