How to use

  1. Open the Reladraw playground
  2. Paste the source above — the diagram re-solves live
  3. Export SVG from the playground, or render locally: npx reladraw cdn-edge-architecture.reladraw -o out.svg

When to use this template

Traffic from users through edge PoP and shield region to origin, with WAF inspection at the edge.. Use it to explain cache hit paths and where TLS terminates.

How to customize

  1. Add a step or node. Insert one line: node new_id 'New label' below anchor — placement is relative, so the solver re-flows the whole diagram instantly.
  2. Relabel an edge. Edit the text after the arrow: edge a -> b 'your label' — labels are the fastest way to carry rates, protocols or percentages.
  3. Change reading order. Swap a placement word: below to right of rotates a branch sideways without touching any other line.
