This document contains notes from a talk on advanced Terraform techniques. It discusses using Terraform for infrastructure as code to deploy resources across multiple environments like development, staging, and production. It also mentions techniques like separating code into modules, using variables to parameterize configurations, and integrating Terraform with other DevOps tools like Ansible.

18. we can build any type of CI/CD pipeline with Terraform.
You can create your instance with the specific service with Terraform only or you can deploy with other tools.
ansible-pull = good option
No inventory
