マルチリージョン構成におけるTerraformモジュール設計

Learn how to design Terraform modules for multi-region configurations in this 19-minute Japanese language technical talk. Explore Infrastructure as Code (IaC) approaches for efficiently managing and operating distributed systems across multiple geographic regions to enhance cloud infrastructure reliability and availability. Dive into practical aspects of module design including dynamic variable management for region-specific configurations, module segmentation strategies to improve code reusability, and design patterns for maintaining resource consistency across multiple regions. Examine real operational challenges, particularly focusing on proper dependency management between modules to prevent provisioning errors and ensure correct resource creation/deletion sequences when dealing with cross-region resource dependencies.
