Abstract
Distributed transactions that span multiple microservices are more and more realized using the Saga Pattern. However, in case the interaction between microservices fails due to an Service Level Objective (SLO) violation, e.g., insufficient availability, the executed business logic gets significantly impacted when a saga compensates already executed operations. Unfortunately, analyzing such impacts manually and reporting found issues is too slow for modern systems. Therefore, we present Dromi, a model-based tool that traces the impacts of SLO violations across a microservice architecture and, if a violation results in compensations caused by sagas, creates an issue report about the violation’s location and resulting impacts on the business processes. The target audience of this demonstration includes architects and developers, who will be shown how such impacts are detected automatically by Dromi.
