Putting the “Micro” Back in Microservice
Modern cloud computing environments strive to provide
users with fine-grained scheduling and accounting, as well
as seamless scalability. The most recent face to this trend
is the “serverless” model, in which individual functions,
or microservices, are executed on demand. Popular implementations
of this model, however, operate at a relatively
coarse granularity, occupying resources for minutes at a
time and requiring hundreds of milliseconds for a cold
launch. In this paper, we describe a novel design for
providing “functions as a service” (FaaS) that attempts
to be truly micro: cold launch times in microseconds
that enable even finer-grained resource accounting and
support latency-critical applications. Our proposal is
to eschew much of the traditional serverless infrastructure
in favor of language-based isolation. The result is
microsecond-granularity launch latency, and microsecondscale
preemptive scheduling using high-precision timers.
