Terraform module to provision DynamoDB autoscaler.

Autoscaler scales up/down the provisioned OPS for a DynamoDB table based on the load.


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!
