Experience
High Availability App Deployment with Terraform and Ansible
https://github.com/riveragalejandro/ha-deploy-terraform-ansibleDisaster recovery is as easy as providing a new AMI for the instances and changing the region on a variables file for the VPC deployment.
Ansible configures the application and leverages AWS dynamic inventory to apply changes on groups of instances based on instance tags. This can also be configured to use other resources to group instances by.
