Fannie Mae is accelerating its operations with IT infrastructure lifecycle management products like Terraform Enterprise, automating large-scale cloud infrastructure provisioning while mitigating security and compliance risks through policy as code supported by Terraform's Sentinel framework. The company has implemented a comprehensive process for developing Sentinel policies, consisting of five stages: requirements, development, testing, review, and release. This process includes fine-tuning requirements gathering, thinking about performance, reusing code, considering backward compatibility, and adopting a multi-year journey to adopt policy as code in Terraform Enterprise. Fannie Mae has pointed out key areas for other adopters to focus on, including fine-tuning requirements, thinking about performance, reusing code, and considering backward compatibility.
