Deployment ohne Streichhölzer @ code.talks 2015

Endlich, das neue Feature ist fertig! Jetzt muss das Ganze nur noch auf die Server. Wer zieht denn dieses Mal das kurze Streichholz und muss sich für 3 Uhr den Wecker stellen? Genügt eine Downtime von einer Stunde? Hoffentlich gibt es keine Probleme, sonst brauchen wir mindestens zwei Stunden. Klingt vertraut, aber kann man halt nicht ändern? Von wegen! Denn mit den richtigen Werkzeugen und einer verlässlichen Automatisierung wird jedes Deployment zum Kinderspiel. Egal ob Aktualisierung der Linux-Distribution, Deployment der eigenen Anwendung oder Anpassung der Konfiguration - Hand in Hand mit der Paketverwaltung des Betriebssystems lassen sich mit erstaunlich wenig Aufwand selbst komplexeste Umgebungen vollständig automatisiert erstellen und pflegen.
