Nebulizer: Certificate Generation at Scale for Slack Nebula Overlay Network Made Easy

Nebula Network

Slack Nebula is an overlay network. Basically an on-demand VPN mesh system, Nebula allows hosts in different networks and locations to auto-create encrypted communication channels between each other. A virtual interface is provided to the operating system, and a unique IP address. Once communication has been established, the nodes see each other as being on the same LAN.
