Interface migration of a java application to a kubernetes cluster
Brief description
PTA supports the migration of interface functions from an on-premise Linux server to an AWS cloud-based infrastructure. The data transfer is between host systems and Oracle databases. The data import into the oracle database happens via a java application. The migration is carried out while largely retaining the previous application. The first step involves setting up the necessary infrastructure in the AWS Cloud and the transfer paths. After that the java application gets migrated to the new kubernetes cluster environment and necessary adaptions are implemented.
Supplement
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.
Subject description
The interface is used to transfer contract and commission data.
