Vertical Autoscaler Simulator Toolkit

Project description

VASIM

Build coverage

VASIM (Vertical Autoscaling SIMulator) is a tool designed to address the complexities involved in assessing autoscaling algorithms.

VASIM is designed for testing recommendation algorithms, with a particular focus on CPU usage in VMs and Kubernetes pods. The toolkit replicates common components found in autoscaler architectures, including the controller, metrics collector, recommender, and resource updater. It enables a comprehensive simulation of the entire autoscaling system’s behavior, with the flexibility to customize various parameters.

Start here!

Our documentation and working example is in our notebook that shows how to get started simulating your data traces and tuning parameters. Our example provides the 3 things needed to run VASim: (1) a data csv file, (2) an autoscaling algorithm, and (3) a metadata.json file of parameters. Details of all of these can be found in the notebook.
