Multi-tenant distributed systems composed of small services, such
\nas Service-oriented Architectures (SOAs) and Micro-services, raise
\nnew challenges in attaining high performance and efficient resource
\nutilization. In these systems, a request execution spans tens to thousands
\nof processes, and the execution paths and resource demands on
\ndifferent services are generally not known when a request first enters
\nthe system. In this paper, we highlight the fundamental challenges of
\nregulating load and scheduling in SOAs while meeting end-to-end
\nperformance objectives on metrics of concern to both tenants and
\noperators. We design Wisp, a framework for building SOAs that
\ntransparently adapts rate limiters and request schedulers system-wide
\naccording to operator policies to satisfy end-to-end goals while
\nresponding to changing system conditions. In evaluations against production
\nas well as synthetic workloads, Wisp successfully enforces
\na range of end-to-end performance objectives, such as reducing average
\nlatencies, meeting deadlines, providing fairness and isolation,
\nand avoiding system overload.<\/p>\n","protected":false},"excerpt":{"rendered":"
