Building a Self-Sustaining Infrastructure: A Two-Server Docker Setup
Overview
Creating a resilient, self-sustaining infrastructure doesn’t require complex enterprise solutions. With two strategically configured servers and a well-thought-out backup strategy, you can achieve both reliability and security for your self-hosted applications.
The Architecture
Docker Host Server
The primary server runs all application workloads using Docker containers. This containerized approach provides:
- Isolation: Each service runs in its own container with defined resources
- Portability: Services can be easily migrated or replicated
- Consistency: Docker Compose configurations ensure reproducible deployments
The Docker host maintains minimal external exposure, with only essential ports opened to the internet. This reduces the attack surface while still providing necessary services.
