BIAS Autoscaler

BIAS Autoscaler leverages burstable instances for scaling Google Computer Engine instances on GCP. Unlike most of the autoscalers available in the industry, BIAS Austoscaler uses burstable instances for reducing cost and increasing efficiency of cloud resources while maintaining quality of service metrics.


BIAS Autoscaler uses the Google API and Google SDK for scaling out and in Google Compute Engine instances. The Google Cloud Load Balancer is used for tuning the CPU usage of the burstable instances in real time.

Internal design

The internal architecture of the BIAS Autoscaler consists of three major blocks: Controller, Monitor and Scaling Policy.

Languages and frameworks
