VMware vRealize Automation (vRA) and Terraform target different infrastructure workflows. This comparison covers SDDC automation, user experience, VMware integration, security, compliance, and support.
End-to-End Automation: vRA automates the entire software-defined data center (SDDC) lifecycle, from provisioning to decommissioning. Terraform is more limited, focusing only on infrastructure provisioning. User Experience: vRA provides a user-friendly interface, making it easier for non-technical users to request and manage infrastructure. Terraform, on the other hand, requires more technical expertise to use effectively. Integration with VMware: vRA integrates with other VMware products, such as vSphere, NSX, and vSAN, allowing for a seamless experience. Terraform can also integrate with VMware, but it requires more manual effort to set up the integration. Enterprise-Grade Security: vRA includes enterprise-grade security features, such as role-based access control and multi-factor authentication. Terraform does not have built-in security features, requiring additional tools or manual effort to secure the environment. Robust Compliance Features: vRA includes compliance features, such as blueprints that enforce specific policies and standards, making it easier to meet regulatory requirements. Terraform does not have built-in compliance features, leaving it up to the user to ensure compliance. Strong Support: vRA has a large, global community of users and is backed by VMware, a well-established company in the tech industry. Terraform is a relatively new tool with a smaller community, making support and resources more limited. vRA fits an SDDC workflow that needs VMware integrations, a self-service interface, and policy controls in one platform. Terraform fits infrastructure provisioning when the team is comfortable managing state and adding separate controls. I compared both approaches in the three-tier application walkthrough.
