A technical look at remote access architectures that use outbound-initiated, TLS-wrapped tunnels to expose internal services through external endpoints.
The Pattern: Machines establish outbound connections to external endpoints, then expose internal services back through those connections using SSH reverse tunnels wrapped in TLS.
Key characteristics:
Common use cases:
The architecture provides multiple security layers (TLS encryption, mutual TLS, SSH authentication) while maintaining audit trails at the tunnel endpoint.
