Case 07 / live web infrastructure

Configured & live-verified

Shared public web edge.

Three separately owned sites share one public HTTPS edge while preserving hostname, upstream, private-path, certificate, and rollback boundaries.

  • Configured
  • Tested
  • Live-verified
Scope: Three sitesTransport: Public HTTPS on standard portOperating scope: Three owner-operated public sites

Operational problem

One edge had to route several independent services without flattening ownership.

Each site needed public HTTPS, but the shared ingress could not treat hostnames, upstream trust, private paths, or reload behavior as interchangeable. A successful result required both client-facing TLS and validated upstream connections while protecting sibling services from a change.

Constraints

Every boundary had to fail closed and remain recoverable.

  • SNI and hostname enforcement keep each public name mapped to the intended backend.
  • Client-facing certificates are managed automatically.
  • Upstream TLS is validated rather than silently downgraded.
  • DNS automation is narrowly scoped and protected.
  • Configuration validation precedes graceful reload.
  • Sibling-site regression checks and rollback boundaries protect unrelated services.
  • Private paths remain isolated; media delivery preserves byte-range behavior.

Architecture & tradeoffs

Shared ingress, independent trust and routing contracts.

Conceptual shared web edge.

Public HTTPS

External clients connect through a standard encrypted edge with automatic certificate lifecycle.

Validated routing

Host matching, config admission, graceful reload, private-path handling, and rollback define the edge contract.

Upstream TLS

Each independently owned backend retains its own validated identity and service boundary.

External acceptance

Reachability, certificate behavior, redirects, media ranges, and sibling routes are tested from outside the host.

Sanitized conceptual view. Domains, IPs, ports, DNS records, certificate identifiers, credentials, and private paths are omitted.

What Shayne owned

Configuration through public acceptance.

Boundary designSeparated hostname routing, backend ownership, upstream trust, private paths, and sibling-site behavior.
ConfigurationEstablished public HTTPS, automatic certificate management, validated upstreams, and narrowly scoped automation.
Operational safetyRequired configuration validation, graceful reload, regression checks, and rollback.
Live acceptanceVerified public reachability and meaningful routing, certificate, redirect, isolation, and media behavior.

AI role

Configuration assistance did not replace live network proof.

AI-assisted work supported planning, configuration review, diagnostics, and validation. Shayne retained environment ownership, trust and rollback decisions, troubleshooting, and the final external acceptance boundary.

Verification

Three sites exercised at the public edge.

Graceful reloadConfiguration admitted before live replacement.
External checksReachability, redirects, isolation, certificate, and media-range behavior.

Result & operating scope

Live infrastructure supporting three independently owned sites.

The edge was configured, tested, and live-verified for three separate sites. It demonstrates end-to-end operational delivery, hostname isolation, trusted TLS, recoverable configuration changes, and external acceptance at the owner-operated scale.

Operational details are intentionally generalized so the public case study explains the engineering without exposing the live infrastructure.
