Cloud Service Providers deliver their products in form of ”as-a-Service”, which are typically categorized by the level of abstraction. This approach hides the implementation details and shows only functionality to the user. However, the problem is that it is hard to measure the performance of Cloud services, because they behave like black boxes. Especially with Function-as-a-Service it is even more difficult because it completely hides server and infrastructure management from users by design. Cloud Service Prodivers usually restrict the maximum size of code, memory and runtime of Cloud Functions. Nevertheless, users need clarification if more ressources are needed to deliver services in high quality. In this regard, we present the architectural design of a new Function-as-a-Service benchmarking tool, which allows users to evaluate the performance of Cloud Functions. Furthermore, the capabilities of the framework are tested on an isolated platform with a specific workload. The results show that users are able to get insights into Function-as-a-Service environments. This, in turn, allows users to identify factors which may slow down or speed up the performance of Cloud Functions.
@cite_12 identify the need to benchmark different qualities and features of FaaS platforms and present a set of benchmarking approaches. They present a preliminary results for a systematic literature review in support of benchmarking FaaS platforms. The results show that no standardized and industry-wide Benchmark suite exists for measuring the performance and capabilities of FaaS implementations. Their results indicate a lack of benchmarks that observe functions not in an isolated but in a shared environment of a Cloud Service.

The number of available FaaS platforms increases with the rising popularity of a "serverless" architecture and development paradigm. As a consequence, a high demand for benchmarking FaaS platforms exists. In response to this demand, new benchmarking approaches that focus on different objectives continuously emerge. In this paper, we call for community participation to conduct a collaborative systematic literature review with the goal to establish a community-driven knowledge base.
