An Open-Source Benchmark Suite for Cloud and IoT Microservices
Cloud services have recently started undergoing a major shift from monolithic
applications, to graphs of hundreds of loosely-coupled microservices.
Microservices fundamentally change a lot of assumptions current cloud systems
are designed with, and present both opportunities and challenges when
optimizing for quality of service (QoS) and utilization. In this paper we
explore the implications microservices have across the cloud system stack. We
first present DeathStarBench, a novel, open-source benchmark suite built with
microservices that is representative of large end-to-end services, modular and
extensible. DeathStarBench includes a social network, a media service, an
e-commerce site, a banking system, and IoT applications for coordination
control of UAV swarms. We then use DeathStarBench to study the architectural
characteristics of microservices, their implications in networking and
operating systems, their challenges with respect to cluster management, and
their trade-offs in terms of application design and programming frameworks.
Finally, we explore the tail at scale effects of microservices in real
deployments with hundreds of users, and highlight the increased pressure they
put on performance predictability
