• Abstract: Microservices have been a key architectural approach for over a decade, transforming system design by promoting decentralization and allowing development teams to work independently on specific microservices. While loosely coupled microservices are ideal, dependencies between them are inevitable. Often, these dependencies go unnoticed by development teams. Although syntactic dependencies can be identified, tracking semantic dependencies - when multiple microservices share similar logic - poses a greater challenge. As systems evolve, changes made to one microservice can trigger ripple effects, jeopardizing system consistency and requiring updates to dependent services, which increases maintenance and operational complexity. Effectively tracking different types of dependencies across microservices is essential for anticipating the impact of such changes. This paper introduces the Semantic Dependency Matrix as an instrument to address these challenges from a semantic perspective. We propose an automated approach to extract and represent these dependencies and demonstrate its effectiveness through a case study. This paper takes a step further by demonstrating the significance of semantic dependencies, even in cases where there are no direct dependencies between microservices. It shows that these hidden dependencies can exist independently of endpoint or data dependencies, revealing critical connections that might otherwise be overlooked.

  We analyse a microservice dataset released by Alibaba along three dimensions of complexity: scale, heterogeneity and dynamicity. We find that large-scale deployments can consist of tens of thousands of, that support an even broader array of front-end functionality. This diversity is also reflected in call graphs, where we find that whilst front-end services produce dominant call graphs, non-dominant call graphs are rarer and could involve dissimilar microservice calls.

  Many organizations are pursuing the migration of legacy monolithic systems to an architectural style. This process is challenging, risky, time-intensive, and prone to failure while several organizations lack necessary financial resources, time, or expertise to set up this migration process. We propose exposing a legacy system as a microservice application without having to migrate it.

  Learning from fully-unlabeled data is challenging in Multimedia Forensics problems, such as Person Re-Identification and Text Authorship Attribution.

We propose a strategy to tackle Person Re-Identification and Text Authorship Attribution by enabling learning from unlabeled data even when samples from different classes are not prominently diverse.
