PROFILE
Roman Zhuzha
Roman Zhuzha enhanced the hashicorp/terraform-provider-aws repository by improving the reliability of EC2 CPU options updates. He addressed an AWS API requirement by ensuring both CoreCount and ThreadsPerCore values are always sent together when modifying cpu_options, preventing MissingParameter errors during partial updates. Using Go for backend development and leveraging AWS API integration, Roman implemented acceptance tests to validate correct handling of these updates, specifically covering scenarios where only one value changes. His work strengthened CI coverage and reduced API errors, demonstrating a thorough approach to test-driven development and robust handling of Optional+Computed fields within the Terraform AWS provider.

Mar 1, 2026March 2026 monthly summary for the Terraform AWS provider focused on EC2 CPU options reliability. Key feature delivered: ensure both CoreCount and ThreadsPerCore are sent together when modifying cpu_options, with acceptance tests verifying correct handling of partial updates by the AWS API. Major bug fixed: mitigate MissingParameter errors by always sending both values when either changes. Added acceptance tests to cover partial updates (TestAccEC2Instance_cpuOptionsCoreCountOnly and TestAccEC2Instance_cpuOptionsThreadsPerCoreOnly). Overall impact: increased reliability of CPU option updates, reduced API errors, and stronger CI coverage. Technologies/skills demonstrated: Go-based provider development, AWS EC2 API integration, acceptance testing, handling Optional+Computed fields, and test-driven validation of API behavior.
