Why Linux from Windows?
Windows
비교적저렴하다. 그러나서비스를위한 S/W 라이센스를고려한다면결코저렴하지않다. Cost
해킹 및 바이러스에의한피해가심각하다. 또한잦은패치 작업으로인한서비스중단이빈번하다.
Security
패치 및버그수정등의지원은 MS에의존할수밖에없다.Support
Linux competency- cost : 라이센스 가격이 저렴한 오픈소스입니다. 또한 각종 서비스를 위해 오픈 소스 S/W를 사용할 경우 매우 저렴하게
구축할 수 있습니다. - customizable : 필요에 맞게 유연하게 구성할 수 있습니다. 또 클러스터를 위한 새로운 서버는 configuration CD 를
이용하여 손쉽게 단 시간 내에 사용이 가능합니다.- stable & reliable : Gartner Group의 운영체제 평가에서, Linux는 안정성 항목에서 “Excellent” 등급을 받아 RISC UNIX와
동급으로 평가받았으며, Windows NT나 Windows 2000보다 뛰어난 플랫폼입니다.- scalable : 고성능 컴퓨팅 클러스터와 scalability가 중요한, 분산 업무에 적합한 platform입니다. 현재 32way까지 확장
가능하며, 2.6 커널에서는 255way까지 지원 가능합니다.- security : Linux를 구성하는 코드들이 수많은 개발자들에 의해 검토되어, 각종 문제점들이나 버그들을 조기에 해결할 수
있습니다. 또한 Firewall, IDS 등 보안 Tool의 안정적 운영이 가능합니다.- performance : Linux는 적은 시스템 자원만으로도 뛰어난 성능을 보입니다. 보다 빠른 프로세서와 메모리가 있는 경우
역시, 주어진 자원을 최대한 활용하여 최적의 처리 능력 제공합니다.- skill : 시장에 숙련된 리눅스 기술자/개발자들이 많이 있으며, 이는 기존 unix 와 비슷하기 때문에 더욱 가능합니다.

- 2000년 MS 100개의보안취약점보안권고
- DoS공격이큰비중을차지
- 최근에 IIS에 Buffer Overflow 공격이증가하는추세
Concerns & Issues- Windows platform의취약한보안성
- 사용자/서버관리자의보안인식 부족
- 바이러스, 웜 감염으로인한서비스중단 (ex, 2003.1.25 Slammer worm injection)- 백신프로그램지연대응
- 백신프로그램과기존프로그램의충돌
- 백신프로그램 배포의어려움 (개인업무용 PC, 업무 Server)- 보안패치프로그램의배포의어려움 (개인업무용 PC, 업무 Server)- 보안정책 강제의어려움(보안설정강제, 불법 SW 통제등) 정보자산유출

Migrate Microsoft Web Application to IBM WebSphere Application Server on Linux
Migration of HTML from IIS to IBM HTTP Server- Very Easy, Usually can be manually converted. Just import into WebSphere Studio- Issues
Case sensitivity (Windows is not, J2EE is)Managing links
Migration from ASP to JSP- Tools can help
DiamondEdge, NetCoole, ... : Quick and easy to use. Use on ASPs and import resultant files into WebSphere StudioInsert dependencies into called classes they provide – need licenseCode is not 100% reliableGenerated code needs to be reverse engineered for debugging
- Manual conversionImport into WebSphere StudioRename files to “.jsp”Manage the linksFix compilation problemsTransactional ASP'sFix case issues
Migration of Components (COM, DCOM, MTS and IDC)- Tools have limited support for migration
DiamondEdge : Quick and easy to use. Use on Visual Basic .BAS Modules and import resultant files into development environmentInsert calls to proprietary librariesCode is not 100% reliableGenerated code needs to be reverse engineered for debugging
- Issues to be aware of Transactions, Remotability, Database Access
