Note:
|
||||
- in der Praxis mehr Knoten
|
||||
- wechselnde Admins
|
||||
- Dokumentation veraltet schnell
|
||||
- sowohl bestehende Knoten müssen aktuell gehalten werden,
|
||||
als auch neue eingerichtet
|
||||
- Komplexe Shell-Skripte sind schlecht maintainbar,
|
||||
häufig nicht portable und langsam
|
||||
- Problem wird durch Konfigurationsmanagements gelöst.
|
||||
- Grundidee: Infrastruktur wird durch eine Konfigurationsdatei oder Sprache beschrieben
|
||||
und das Konfigurationsmanagement, versucht diesen Zustand herzustellen.
|
||||
- Hier ein paar Beispiele, Im folgenden werde ich näher auf chef und Puppet
|
||||
eingehen.
