„Everything as Code“ with Terraform and Ansible

Automation in IT always takes place on different levels: On the one hand, it requires the management of infrastructure, such as (virtual) servers and network components. On the other hand, this infrastructure also needs to be configured and populated with applications. A key role in the automation of these two levels is played by their formulation in declarative form - one speaks of "Infrastructure as Code" and "Configuration as Code". A popular combination for implementing this concept is to manage infrastructure using Terraform, while Ansible handles application installation and configuration. The only problem: how should the two programs communicate with each other? In this talk, I will present various interfaces between Terraform and Ansible, ranging from completely separate workflows, to the joint packaging of "Terraform-Ansible code".
