We present Theodolite, a method accompanied by an open source implementation for benchmarking the scalability of such microservices as well as their employed stream processing frameworks and deployment options. According to common scalability definitions, Theodolite provides detailed insights into how resource demands evolve with increasing load intensity. However, accurate and statistically rigorous insights come at the cost of long execution times, making it impracticable to execute benchmarks for large sets of systems under test. To overcome this limitation, we raise three research questions and propose a research agenda for executing scalability benchmarks more time-efficiently and, thus, for running scalability benchmarks at large scale.enmicroserviceTheodolitescalabilityloadbenchmarkText/Conference Paper0720-8928
