Google Cloud Sunsets Deployment Manager, Pushing Users Towards Infra Manager for Modern IaC Workflows

Google Cloud has officially deprecated its Deployment Manager service, effective April 1, 2026, with a complete shutdown slated for June 30, 2027. Existing users can continue to manage their deployments "at their own risk" until the final shutdown, but new customers are already blocked from enabling the service or creating new deployments as of June 30, 2026. Google Cloud will not be providing standard support for Deployment Manager issues, nor will there be any new features or critical bug fixes. The company is actively redirecting users to its newer Infrastructure Manager (Infra Manager) service, urging all current Deployment Manager users to migrate to Infra Manager or another suitable deployment technology to ensure uninterrupted service. This move is highly significant for anyone operating infrastructure within Google Cloud. It's not merely a technical upgrade but a strategic pivot by Google Cloud to standardize on a more advanced and integrated IaC platform. For practitioners, this means that the older, YAML-based configuration approach of Deployment Manager is no longer considered a viable long-term strategy. The shift to Infra Manager, which is built on Terraform, reflects a broader industry trend towards more powerful, flexible, and widely adopted IaC frameworks. Ignoring this deprecation will inevitably lead to operational challenges, including lack of support, inability to leverage new cloud features, and potential security vulnerabilities as the deprecated service receives no further updates. This development aligns with the broader, well-established trend in cloud and DevOps where IaC is becoming increasingly sophisticated and integrated. The IaC market is projected to reach $3.3 billion in 2026, with a strong emphasis on automation, governance, and resilience. Tools like Terraform and Pulumi have become dominant for provisioning across multiple cloud providers, offering declarative approaches and extensive ecosystems. The industry is moving towards platforms that offer not just provisioning but also continuous governance, drift detection, and automated remediation. The deprecation of Deployment Manager and the push towards Infra Manager is Google Cloud's way of ensuring its users are equipped with tools that meet these modern IaC demands, particularly in multi-cloud and hybrid environments where consistency and control are paramount. In practice, practitioners currently using Google Cloud Deployment Manager should immediately begin assessing their existing deployments and planning a migration strategy. This involves identifying all resources managed by Deployment Manager, understanding their dependencies, and evaluating whether Infra Manager or another IaC tool like Pulumi or OpenTofu is the best fit for their future needs. The migration offers an opportunity to modernize IaC practices, implement stronger policy-as-code guardrails, and integrate with more advanced CI/CD pipelines. Teams should prioritize this migration to avoid being left with unsupported infrastructure and to leverage the enhanced capabilities that modern IaC platforms provide for managing complex, scalable, and secure cloud environments. Failure to act will result in a forced, potentially disruptive transition as the June 2027 deadline approaches.
