Abstract:
Since its appearance in mid-2014, there has been notable growth in the adoption of cloud services via the Function-as-a-Service (FaaS) model, with several public cloud providers offering this model in their catalog. Various papers have mostly evaluated the performance of these models in public cloud environments. However, the implementation of this model in a private cloud environment has not been explored enough by the academic community. This article presents a two-level factorial design-based assessment of the main open-source operating platforms (Such as OpenWhisk, Fission, and OpenFaaS) currently available to serve as a comparative tool that can be used in decision-making processes. Results showed that regarding the stress test the OpenWhisk platform has greater reliability. On the other hand, regarding the processing of the Matrix, Factors, and Filesystem functions, Fission remains at similar behavior at all concurrency levels.
