Essential Terraform best practices for organizing and structuring your infrastructure code: 1. Separate Configuration Files Instead of putting all code in main.tf, distribute it across multiple files: main.tf: Calls modules, locals, and data sources to create all resources variables.tf: Contains variable declarations used in main.tf. Place required variables at the top and optional ones at the bottom, separated by a comment line for better readability outputs.tf: Contains outputs from resources created in main....

GitHub’s platform engineering team shares their approach to tackling infrastructure challenges at scale. Key strategies include: Understanding your domain: Talk to neighboring teams with more experience Investigate old issues to understand system limitations Read documentation to build foundational knowledge Platform-specific skills: Network fundamentals (TCP, UDP, L4 load balancing, debugging tools) Operating systems and hardware selection for scalability and cost Infrastructure as Code (Terraform, Ansible, Consul) Distributed systems understanding (failures are inevitable, need failover/recovery) Impact radius considerations:...
