Multi-Server, Multi-App, Multi-Service Orchestrator.

DHermes — Multi-Server, Multi-App Enviroments Orchestrator (DevOps-as-Code)

Hermes is a robust and extensible environment manager designed to orchestrate complex DevOps workflows across multiple servers, applications, and services.

It provides a DevOps-as-Code interface that simplifies:

• Infrastructure provisioning
• Application deployment
• Service lifecycle management
• Event-driven automation
• Secure multi-server credentials handling

Built with flexibility and scalability in mind, Hermes allows teams to define environments declaratively using a lightweight DSL (YAML), enabling:

• Seamless coordination of distributed deployments
• Reusable, composable event hooks (e.g., onDeploy, onUpdate)
• Specific Environment server/app/service configurations
• Importable configuration modules for better DRY practices

Use Cases

• Deploy microservices to different VMs with event-triggered hooks
• Spin up isolated dev/stage/prod environments with different configs
• Automate CI/CD operations per service/app/server or global
• Centralize infrastructure configuration in a single source of truth
