This architecture can be deployed independently while also serving as a foundational deployable architecture for other architectures like [Cloud automation for Red Hat OpenShift AI](https://cloud.ibm.com/catalog/7a4d68b4-cf8b-40cd-a3d1-f49aff526eb3/architecture/deploy-arch-ibm-ocp-ai-ba708aed-bb8a-4ac0-83a7-53a066701db5-global) to deploy mission critical applications and AI-driven initiatives to market quickly and securely with a managed OpenShift service.\n\nℹ️ This Terraform-based automation is part of a broader suite of IBM-maintained Infrastructure as Code (IaC) assets, each following the naming pattern \"Cloud automation for *servicename*\" and focusing on single IBM Cloud service. These single-service deployable architectures can be used on their own to streamline and automate service deployments through an [IaC approach](https://cloud.ibm.com/docs/secure-enterprise?topic=secure-enterprise-understanding-projects), or assembled together into a broader [automated IaC stack](https://cloud.ibm.com/docs/secure-enterprise?topic=secure-enterprise-config-stack) to automate the deployment of an end-to-end solution architecture.",
