The solution
The aim of PEDA-S 4.0 was to fully migrate these vast amounts of data: not only to a contemporary application, but also to PostFinance’s private Kubernetes cloud at the same time. The latter is a first in the history of PostFinance – PEDA-S was the first major core application to be transferred to its own cloud successfully, making it the example to follow for other applications.
The way the migration was done was also something out of the ordinary: the countless interfaces and dependencies to the periphery systems meant that the release has to be migrated in a ‘big-bang approach’ rather than be introduced gradually. As the name suggests, PEDA-S 4.0 was successfully introduced over a release weekend and, above all, synchronously with other applications. This was only possible thanks to the intensive testing carried out by adesso and the close collaboration with PostFinance employees.
