Interface migration of a java application to a kubernetes cluster

The migration is necessary because onpremise servers will be decommissioned at the customer in the future. The previous direct data transfer from the host to the Linux via Connect:Direct is no longer possible in this form. IBM Sterling File Gateway is therefore used for data transfer between the host and the AWS Cloud. In the new infrastructure, there is also a strict separation between data storage and processing logic. Scheduling is done using cron jobs in the java application. The transfer files to be processed are stored in an S3 (simple service storage) bucket, which the java application can access. Afterward the application writes the proccessed data in a oracle database.
