Systems Integration Application

Digitalisation is a hot topic in the modern world that aims to create better services that are more available and accessible. Transaction times for anything and everything needs to be as short as possible, and usable by virtually anyone, at anytime and anywhere. This thesis investigates the digitalisation project of one Finnish government agency. The agency deals with resource usage applications in paper forms via postal mail. They have recently acquired new digital systems for the application and archival procedures to replace their physical world counterparts. Even with brand new digital systems, the clerks must still deal with the processes of handling applications manually. The topic of this thesis was to create a systems integration application that ties three individual information systems together and automates data flows between them. The new integration application aims to streamline the resource application process for clients, and to help ease manual work tasks of the clerks. The product of this thesis was a brand new software application. The application was developed to be highly available through asynchronicity and easily maintainable and deployable through containerisation and configurability. The application was designed as a central relay hub for horizontal integration model using a stateless architecture to ensure problem free operation
