    A look at service meshes
    (2021) Koschel, Arne; Bertram, Marvin; Bischof, Richard; Schulze, Kevin; Schaaf, Marc; Astrova, Irina [in: The 12th International Conference on Information, Intelligence, Systems Applications, 12-14 July 2021, Chania, Crete, Greece]
    Service meshes can be seen as an infrastructure layer for microservice-based applications that are specifically suited for distributed application architectures. It is the goal to introduce the concept of service meshes and its use for microservices with the example of an open source service mesh called Istio. This paper gives an introduction into the service mesh concept and its relation to microservices. It also gives an overview of selected features provided by Istio as relevant to the above concept and provides a small sample setup that demonstrates the core features.

    Cloud computing: serverless
    (IEEE, 2021) Koschel, Arne; Klassen, Samuel; Jdiya, Kerim; Schaaf, Marc; Astrova, Irina [in: 12th International Conference on Information, Intelligence, Systems and Applications, 12-14 July 2021, Chania, Crete, Greece]
    A serverless architecture is a new approach to offering services over the Internet. It combines BaaS (Backend-as-a-service) and FaaS (Function-as-a-service). With the serverless architecture no own or rented infrastructures are needed anymore. In addition, the company does not have to worry about scaling any longer, as this happens automatically and immediately. Furthermore, there is no need any longer for maintenance work on the servers, as this is completely taken over by the provider. Administrators are also no longer needed for the same reason. Finally, many ready-made functions are offered, with which the development effort can be reduced. As a result, the serverless architecture is very well suited to many application scenarios, and it can save considerable costs (server costs, maintenance costs, personnel costs, electricity costs, etc.). The company only must subdivide the source code of the application and upload it to the provider’s server. The rest is done by the provider.

    Towards a microservices-based distribution for situation-aware adaptive event stream processing
    (2019) Schaaf, Marc
    This paper presents the central concepts for a microservices-based distribution of event stream processing pipelines as they are part of our situation-aware event stream processing system. For this, we outline changes to our specification language for a clear separation of the stream processing specification from the actual stream processing engine. Based on this separation, we then discuss our mapping approach for the assignment of the pipelines to stream processing nodes.

    A service based architecture for situation-aware adaptive event stream processing
    (2018) Schaaf, Marc [in: SERVICE COMPUTATION 2018: The Tenth International Conference on Advanced Service Computing]
    This paper presents the central aspects of a service based architecture for a distributed event stream processing system with an emphasis on its components, as well as related scalability and flexibility considerations. The processing system architecture is designed based on a well-defined situation-aware adaptive event stream processing model and a matching scenario definition language, which allow the definition of such processing scenarios in a processing system independent way.
