Lessons from Platform Engineering at Scale

Architecting Enterprise-Grade GitOps with OpenTofu: Lessons from Platform Engineering at ScaleAs platform engineering teams scale Infrastructure as Code (IaC), they face a key architectural challenge: balancing developer autonomy with centralized security, compliance, and control. While GitOps offers a declarative model for infrastructure management, adopting it at scale often reveals gaps in traditional tooling—especially when using open-source IaC like Terraform.

In this webinar, Rohit Reddy from Harness shares patterns, design lessons, and insights from building a GitOps-first IaC platform using OpenTofu—the open-source Terraform fork backed by the Linux Foundation. Learn how teams can evolve from ad hoc scripts to policy-driven workflows integrated into the delivery lifecycle.

What You’ll Learn:

• Trade-offs between GitOps, imperative IaC, and event-driven provisioning
• Designing modular, auditable IaC repositories for scale
• Building policy-as-code for security, cost, and compliance
• Lessons from adopting and running OpenTofu in production
• Inside Harness’ GitOps IaC architecture: policy engines, workflows, feedback loops
