SUSE Multi-Linux Manager Server Air-gapped Deployment

1. What is Air-gapped Deployment?

Air-gapped deployment refers to the setup and operation of any networked system that is physically isolated from insecure networks, especially the internet. This type of deployment is commonly used in high-security environments such as military installations, financial systems, critical infrastructure, and anywhere sensitive data is handled and must be protected from external threats.

2. Deployments

SUSE Multi-Linux Manager supports two deployment variants.
