Background:
The central exchange platform allows the exchange of information for different scenarios between social security providers and other relevant bodies. The technical transformations of the modules for insurance periods, sickness insurance membership, electronic disability certificates and claims for reimbursement are harmonised and carried out in the form of microservices. The following microservices are currently included:
Notification: This microservice transforms, treats and forwards information in the context of insurance periods, sickness insurance membership and electronic disability certificates.
Claim: This microservice is responsible for the transformation, treatment and transmission of information in the context of refund claims.
The interfaces and components for communication with external partners and internal IT processes are implemented through a container platform with technologies such as dockers, Kubernets, Prometheus, Grafana and ELK stack. The integration takes place via asynchronous microservice technology and interfaces such as Kafka, REST, SOA and file interfaces. An Oracle database is used as a database.
