dspace-group / simphera-reference-architecture-aws

In order to deploy SIMPHERA to AWS, various cloud resources, such as a Kubernetes cluster, PostgreSQL database server, etc., need to be created. This repository contains a reference architecture for these AWS resources. You can use this Terraform configuration as a starting point to create these resources in your own AWS account.
