Terraform has introduced project-owned variable sets to provide more flexible controls over access and usage, simplifying management, reducing dependencies, and allowing for granular permissions. This feature addresses the need for more control within projects while ensuring consistency and security across multiple workspaces. With project-owned variable sets, users can define variables once and reuse them across multiple workspaces within a specific project, eliminating the need for manual duplication of sensitive data or reliance on platform teams for variable set management. The new feature offers benefits such as facilitating the transition to projects, simplifying variable set management, granular control over variable sets, and increased operational efficiency, ultimately empowering project teams with the control they need to manage their infrastructure efficiently while maintaining a high level of security and governance.
