Resumen:
In the paper Controlling Garbage Collection and Request Admission
to Improve Performance of FaaS Applications[30], we veriied
and evaluated the impact of memory management mechanics of
programming languages in the context of Functions as a Service
(FaaS) via simulation experiments. The results of this study pointed
to an impact of up to 11.68% on the response time of requests when
a garbage collector procedure was executed during the execution
of a CPU-bound function. As future work, we listed a few threats
to the validity of the results attained, and among them, we cited
the validation of the simulation model used. The validation of the
model is important because it validates the results generated in
the simulation experiments, which ensures realistic results. In this
work, we proposed and executed a validation to the simulation
model used in the previous work. To do so, we run measurement
experiments in a public FaaS platform and simulation experiments
of the same scenarios using the same simulator of the previous
paper. Then, we validate the simulator by comparing the results
obtained in both experiments to ensure that the simulation result
and the measurement one are equivalent.
