Architecture Advisory Deep Lens
Structured critique of service boundaries, data paths, and failure domains with annotated visuals.
Narrative
We walk layered diagrams of your runtime, data stores, and async pathways. The emphasis is on coupling points that ripple during incidents and the operational signals that should exist before you expand internationally.
Scope notes
- Context diagrams with explicit trust boundaries
- Failure domain overlays on deployment topology
- Contract sketch for highest-churn APIs
- Data lineage notes for regulated payloads
- Capacity assumptions versus measured usage
- Observability gap list with suggested signals
- Plain-language brief for non-engineering sponsors
Outcomes
- An architecture narrative engineers and sponsors both recognize
- Prioritized refactors that reduce incident blast radius
- Shared criteria for future service splits or merges

Client notes
Failure domain overlays finally explained why our staging drills never matched prod — specific to the Deep Lens diagrams.
Plain-language brief saved a painful sponsor meeting; still wish the API contract sketch had one more revision cycle.
Client in enterprise IT — Observability gap list became our Q3 instrumentation backlog.
FAQ lane
Yes — we explicitly surface strangler seams and incremental extraction angles rather than rip-and-replace fantasies.
