InVitro

In-Vitro is a set of tools for analyzing the performance of serverless cluster deployments. In-Vitro consists of two tools, namely sampler and loader. Sampler creates representative workload summaries (i.e., samples of functions) based on production traces. Loader reconstructs the invocation traffic based on a given trace and steers this load to the functions deployed in the studied serverless cluster. Currently, In-Vitro supports vHive and OpenWhisk. Documentation on how to use the sampler and the loader can be found in the docs folder.

Standard sampled traces are available in data/traces/reference folder in this repository. The traces are sampled from the Azure Functions production traces using the sampler tool. More details on the sampling process can be found here.
