Cloud Resilience Is IaC's #1 Benefit in 2026, But Most Teams Still Can't Deliver On It

Infrastructure practitioners are increasingly focused on achieving infrastructure immutability and rebuild confidence through Infrastructure as Code (IaC) by 2026, but many teams fall short in fully realizing this goal. Despite widespread adoption of IaC, with pipelines running and modules versioned, only 11% of teams have tested and validated disaster recovery (DR) capabilities, revealing a significant gap between expectations and actual performance. This discrepancy arises from issues such as reliance on manual validation, inadequate codification of infrastructure, and the accumulation of "ClickOps debt," where not all infrastructure elements are represented in code. The 2026 State of Infrastructure as Code report highlights that while most organizations have IaC, they lack the confidence to execute a reliable recovery due to untested DR procedures and incomplete infrastructure codification. As AI agents become more involved in infrastructure management, the need for robust, automated DR capabilities intensifies, making it critical for teams to continuously reconcile code with live cloud states and prioritize codification as an integral part of infrastructure management rather than an afterthought.
