# Design Doc: Horizontal Autoscaling
# Design Doc: Elastic Deep Learning

## Background

A PaddlePaddle training job contains several trainer instances,
several parameter server instances, and one master instance. We would
like to automatically scale the number of training instances and the
number of parameter server instances to fully utilize the cluster's
computation resources.
computation resources. We call this Elastic Deep Learning.

Currently, we will only support horizontal trainer
autoscaling. Parameter server horizontal autoscaling will be supported
in the near future. This design doc considers both of them.
