Infrastructure as code with Terraform
summary
Presentation explains Terraform (HashiCorp Configuration Language) for defining infrastructure as code, showing Terraform 0.11.8 examples that create a VPC, a security group and two AWS EC2 instances and noting the upcoming 0.12 language upgrade. It covers how state is stored in a tfstate file or remote backends, graph-based plan execution that enforces idempotence and resource ordering, use of modules to encapsulate topology, data sources to find existing VPCs by tags, and available providers (AWS, GCP, Azure, etc.), plus a repository with 1,230 contributors.
