Connection of a PKV calculation kernel to clerk clients and host processes via cloud web service

Up to now, the calculation kernel has been delivered in three different environments. The Windows clients of the clerks call the locally installed calculation kernel for contribution calculation and other processes. As part of the dark processing of the applications submitted by insurance representatives, the calculation kernel is called in a Linux environment. There are various batch processes on the host, such as premium adjustments, dynamization of additional nursing care tariffs or calculation of reserves, which call the calculation kernel. In order to simplify and reduce the computing time on the host (cost savings), the calculation kernel should only be executed in a Linux environment in the AWS cloud within an application server (WebSphere Liberty) and made available to all platforms. The callers of the computing kernel must be switched so that not a local but the cloud calculation kernel is called. This should be done with as few changes as possible in order to minimize conversion costs and risks.
