Working on NetBox Designs: https://netboxlabs.com/blog/netbox-designs-introducing-decla...
Infrastructure architects think in terms of building blocks in "high-level designs" and those building blocks are often socialised/expressed in Visio/Spreadsheets. Thinking in building blocks is now more necessary than ever because of the sheer size of the infra being designed/deployed.
This approach is problematic after the design phase because there's a lossy translation to where the low-level design lives, often referred to as the Source of Truth, like NetBox.
NetBox Designs allows users to express composable, versioned, and templatizable building blocks that can be rendered to low level designs. No lossy translations, and you can always check in the future "does my LLD still match my HLD and if not, where?"
