Adaptable TeaStore (2412.16060v1)

Abstract: Adaptability is a fundamental requirement for modern Cloud software architectures to ensure robust performance in the face of diverse known and unforeseen events inherent to distributed systems. State-of-the-art Cloud systems frequently adopt microservices or serverless architectures. Among these, TeaStore is a recognised microservice reference architecture that offers a benchmarking framework for modelling and resource management techniques. However, TeaStore's original configuration lacks the flexibility necessary to address the varied scenarios encountered in real-world applications. To overcome this limitation, we propose an enhanced variant of TeaStore that distinguishes between mandatory and optional services while incorporating third-party service integration. Core services such as WebUI, Image Provider, and Persistence are designated as mandatory to maintain essential functionality, whereas optional services, such as Recommender and Auth, extend the architecture's feature set. We outline the design and configuration possibilities of this adaptable TeaStore variant, aimed at enabling a broader spectrum of configurability and operational resilience.
