Abstract:
This paper demonstrates and evaluates the technical improvement of an existing prototype of the STIMEY e-learning platform based on a microservices architectural pattern. The first approach is using our page fragments technology that allows to integrate contents of other microservices in a superordinate context but lead to difficulties regarding maintenance. The second approach holds all page fragments in one microservice, and the specific data is provided separately by domain-specific microservices which makes it easier to work with them, in case of the STIMEY platform, because domain-specific designers can now be assigned to just one respective microservice. Additionally, a conception to migrate the platform to Amazon Web Services (AWS) in the future is shown. A novel three-dimensional architecture model is introduced to visualize the used microservices’ architectural pattern. Three patterns are shown for the data access of the individual microservices and for their interconnectedness. At the end, it is discussed how the database design can be implemented.
