virtuoso-opentofu: Self-managed OpenTofu Deployments for Virtuoso Universal Server

The repository provides self-managed OpenTofu deployment scripts for OpenLink Virtuoso Universal Server across supported cloud providers. It is for self-managed deployments only and does not contain the managed SaaS control plane, Marketplace integration, customer portal, seller admin portal, or operational evidence used by the managed service.

Supported providers are AWS (available, ECS Fargate + EFS), Azure (available, Virtual Machine + Managed Disk), Azure ACI (experimental, Container Instances + Azure Files), and Google Cloud (available, Compute Engine + Docker + Persistent Disk + Secret Manager).

Operators choose the cloud provider directory and run OpenTofu from inside that directory (tofu init, validate, plan, apply). Each provider directory is intentionally self-contained with its own README.md, versions.tf, variables.tf, outputs.tf, terraform.tfvars.example, deployment helper script, and provider-specific modules. Multiple deployments are supported within the same cloud account, subscription, or project using separate OpenTofu state per deployment plus a distinct naming prefix such as project_name.

Potential future additions under consideration are azure/aks/ (Kubernetes-based Azure variant using AKS with Azure Disk for the live database volume) and gcp/gke/ (Kubernetes-based Google Cloud variant using GKE with Persistent Disk for the live database volume). The current recommended single-instance self-managed baselines remain Azure VM + Managed Disk and GCP Compute Engine + Persistent Disk.

Managed SaaS implementation files must not be added to this repository; they remain in the private or full development repository. Excluded by design are AWS Marketplace SaaS registration and metering code, customer and seller portal source code, managed SaaS control-plane Lambda/API/CodeBuild/OpenTofu code, Marketplace private offer JSON files, Marketplace validation evidence, and Terraform or OpenTofu state files and local terraform.tfvars.

Head-to-head comparison of the AWS, Azure, and Google Cloud self-managed deployment baselines across compute platform, storage, secrets management, status, recommended baseline, and future Kubernetes path.
