The good, the bad, and the ugly of migrating hundreds of legacy applications to a cloud native platform

Wir haben bei der Allianz innerhalb von 17 Monaten eine Container Plattform in der Public Cloud aufgebaut und in einem ersten Schritt 144 Java Legacy Anwendungen cloud-ready gemacht und dorthin migriert. Im Vortrag zeigen wir, was dabei unsere Erfolgsrezepte und größten Hindernisse waren. Es geht dabei unter anderen darum, wie man eine große Anwendungslandschaft auf ihre Cloud-Readiness hin analysiert und wie man eine industrialisierte Migration von Anwendungen auf eine Cloud Plattform etabliert.
