Terraform Cloud has introduced a new organizational structure called projects, which allows users to isolate subsets of workspaces and define permissions within a single organization. This feature helps users organize and centrally manage their workspaces at scale while providing more granular permissions to a subset of workspaces. The introduction of projects aims to address the challenges in workspace management, such as lack of flexibility and complex workarounds, limitations with organization-level permissions, and reduced risk with centralized control. With projects, teams can safely self-manage workspaces and enable organization admins to create logical ownership boundaries to ensure security. Projects also provide increased agility with workspace organization, reduced risk with centralized control, and better efficiency with self-service capabilities.
