Diagrammes d'architecture réseau

Network diagrams people can point at

Network architecture diagrams usually fail at the pointer test: in a review, nobody can point at the path a packet takes. Icons float without frames, subnets are implied, and the firewall might as well be decorative. A network topology canvas passes the test by making the path visible, from the Internet to DNS to load balancer to firewall to VPC and subnet frames, with servers or Kubernetes workloads inside them. Orthogonal edges carry the hops cleanly; labeled edges carry the policy, like which port the firewall allows. When the whole path is on one board, the review moves from guessing to deciding.

Frame aggressively. VPC and subnet frames turn a pile of servers into an address plan reviewers can read: public subnets hold the load balancer, private subnets hold the workloads, and the firewall sits visibly between the edge and everything else. Add a legend for the review audience, because reviewers who do not live in the network still need to read it. Put DNS early in the path; half of all network mysteries start with name resolution, and the diagram should say so.

From topology sketch to change ticket

A network diagram becomes operational when it attaches to the change process. Export an SVG or PNG for the ticket, share a branded public link for the pre-launch review, and snapshot a revision before the firewall rule changes, since the before-shape is the fastest way to roll a conversation back. Keep the Kubernetes workloads that sit behind the firewall on the same canvas instead of a separate drawing; the subnet frame should contain what it actually routes to, whether that is servers or Pods. Tickets with a live link get approved faster than tickets with a stale screenshot.

The Network pack ships on Free with Cloud, Security, and Kubernetes packs beside it, because topologies never stop at the subnet edge. Combine Internet, router, switch, and CDN nodes with the firewall and VPC frames, and let the canvas hold the whole story from edge to workload. Pro adds embed plus watermark-free snapshots for the tickets that leave the platform team. Draw the path the packet takes, and then point at it.
