Relationship Graph + RDE Architecture Deep Dive

How dependency structure is stored, kept current, and traversed for cause and impact reasoning.

For technical evaluators who need to verify that a dependency model holds up during real operations.

Validate dependency accuracy in your environment. (No credit card required)

Validate in 60 Minutes

Use this deep dive to guide a fast technical evaluation. In a live trial, you should be able to:

• Trigger a known change and see nodes and relationships update
• Traverse 3–5 hops upstream and downstream without performance collapse
• Inspect a readable, node-by-node dependency path behind an answer
• Converge on a shared upstream dependency across multiple symptoms
• Confirm redundancy prevents false service degradation
• Spot red flags like stale links, duplicate entities, or black-box results

This is an architecture deep dive focused on update behavior and traversal.

It explains:

It does not cover UI workflows or screenshots.

If you are evaluating correctness, explainability, and operational trust under stress, this document is built for you.

This deep dive is written for technical evaluators who need to confirm that dependency reasoning works in real environments:

Platform and infrastructure architects
Validate model correctness and change impact behavior.
SRE and incident response leads
Test cause isolation, blast radius, and noise reduction.
Security architects and technical evaluators
Confirm scope of exposure and containment boundaries.

Modern systems are interconnected and constantly changing.

When something breaks, the slow part is rarely the fix. The slow part is proving what failed first and what else is affected.

Most tools reconstruct dependencies during an incident. WanAware maintains them continuously.

If dependency structure is not current, explainable, and fast to traverse, it will not be used during incidents.

After reading this deep dive, you should be able to:

Understand what the Relationship Graph represents (a stored data model, not a picture)
Understand what RDE does (evidence → relationships → updates over time)
See how traversal supports upstream cause isolation and downstream impact scoping
Understand how the model stays current as assets scale, move, and retire
Use a short checklist to test correctness and trustworthiness during a trial

The modern dependency problem
Why list-based tools and bolt-on graph views drift or slow down under pressure.

The Relationship Graph data model
Nodes, relationships, and the questions the model must answer:

RDE update behavior
How relationships are normalized, deduplicated, reconciled, marked stale, retired, and flagged when evidence conflicts.

Traversal and reasoning

Data hierarchy and stability
Assets → Collections → Service Elements → Structures
How services remain stable while underlying assets change.

Service health and redundancy awareness
How health rolls up without turning single-component noise into service outages.

This document focuses on how the dependency layer behaves under real operational stress.

Read this if you are:

Dependency reasoning only works when the structure behind it is current, inspectable, and built for traversal.
