This partnership between HashiCorp and Microsoft enables the creation of a reference architecture for Terraform modules that follow Microsoft's Azure Well-Architected Framework and security best practices. The architecture uses an N-tier model, which is commonly used for traditional on-premises applications migrating to Azure infrastructure. The solution incorporates three key security utilities: Microsoft Defender for Cloud, dynamic provider credentials in Terraform Cloud, and HashiCorp Cloud Platform (HCP) Vault. These tools provide a defense-in-depth approach to cloud vulnerabilities, enabling organizations to maintain secure and reliable infrastructure while adhering to compliance and best practices. By integrating these security features into an infrastructure as code workflow, organizations can ensure their cloud deployments are secure, compliant, and easily maintainable.
