SignalWeaver

Cross Domain Event Platform

🎯 Our Mission

To enable organizations worldwide to share event-driven data across boundaries—securely, reliably, and using open standards—without building custom integration infrastructure.

❓ The Problem We Solve

🔗 Integration Complexity

Every organization builds custom webhooks, event systems, and integration APIs—reinventing the wheel for event-driven communication. This leads to:

Duplicated infrastructure
Inconsistent event formats
Fragile point-to-point integrations
No centralized event discovery

🚧 Trust Boundaries

Events need to flow across organizational boundaries, but traditional event systems weren't designed for this:

Hard to secure cross-organization access
No standard authentication model
Difficult to track delivery and acknowledgements
Manual subscriber management

📊 Lack of Visibility

Once events are published, organizations lose visibility:

Did the subscriber receive it?
Was it processed successfully?
Where did delivery fail?
No centralized monitoring

⚙️ Operational Burden

Running event infrastructure at scale requires:

Managing subscriber webhooks
Retry and dead-letter handling
Event versioning and evolution
Security and compliance

✅ How SignalWeaver Solves This

🌐 Cross Domain Events (CDEs)

SignalWeaver introduces the concept of Cross Domain Events (CDEs)—events that flow across organizational boundaries using the CloudEvents v1.0 open standard.

Instead of building custom integrations, organizations publish and subscribe to standardized events through a managed platform.

1️⃣

Publish Once

Publishers send CDEs using our SDK—no infrastructure setup required

2️⃣

Platform Routes

SignalWeaver handles routing, retry, dead-letter, and delivery tracking

3️⃣

Subscribe Anywhere

Subscribers receive events via webhook with acknowledgement tracking

🏛️ Design Philosophy

SignalWeaver is built on CloudEvents v1.0, the industry-standard specification for event data. This means:

✅ Interoperability with other CloudEvents systems
✅ No vendor lock-in—events are portable
✅ Leverages existing ecosystem and tooling
✅ Future-proof as CloudEvents evolves

Why CloudEvents? Instead of inventing a proprietary format, we use a CNCF-backed standard that's supported by AWS, Azure, Google Cloud, and more.

Organizations shouldn't need to build event infrastructure. SignalWeaver provides:

✅ Azure Event Grid for reliable delivery
✅ Automatic retry with exponential backoff
✅ Dead-letter queue for failed deliveries
✅ Built-in monitoring and health checks

Why managed? Running event infrastructure at scale is complex. We handle the operational burden so you can focus on business logic.

The SignalWeaver SDK is designed to "just work" with minimal configuration:

✅ Single NuGet package for publishing and subscribing
✅ Automatic CloudEvent serialization/deserialization
✅ Built-in retry and error handling
✅ Aspire-ready with service discovery

Philosophy: Five lines of code should get you from zero to publishing events. Complexity is opt-in, not mandatory.

Cross-domain events require strong security boundaries:

✅ Microsoft Entra External ID for authentication
✅ Publisher/Subscriber isolation via claims-based authorization
✅ HTTPS-only event delivery
✅ Webhook validation before subscription creation

Trust model: Publishers control who can subscribe to their events. Subscribers receive only events they're authorized for.

You should never wonder "Did my event get delivered?":

✅ Real-time delivery tracking via dashboard
✅ Subscriber acknowledgement flow
✅ Structured logging with correlation IDs
✅ Health checks for all endpoints

Visibility matters: Every event has a complete audit trail from publish → delivery → acknowledgement → processing.

💡 Real-World Use Cases

🛒 E-Commerce Order Flow

Scenario: An e-commerce platform needs to notify external partners when orders are placed.

With SignalWeaver:
Publish order.placed → Partners subscribe → Automated fulfillment, accounting, and inventory updates across organizational boundaries.

💳 Payment Processing

Scenario: Payment gateway needs to notify merchants of successful/failed payments.

With SignalWeaver:
Publish payment.processed → Merchants subscribe → Real-time notification without polling or custom webhooks.

🏥 Healthcare Integration

Scenario: Hospital systems need to notify labs, pharmacies, and billing when patient events occur.

With SignalWeaver:
Publish patient.admitted → Authorized subscribers receive → Cross-organization workflow without point-to-point integrations.

📦 Supply Chain Events

Scenario: Shipping logistics need to notify multiple parties of package status changes.

With SignalWeaver:
Publish shipment.updated → Suppliers, warehouses, and customers subscribe → End-to-end visibility.

🏗️ Architectural Principles

Note: This section explains why we made architectural decisions, not the technical implementation details.

🎯 Event Registry as Catalog

Why: Organizations need to discover what events are available before subscribing. The Event Registry provides a centralized catalog—like a "marketplace" for events.

🔄 Publisher/Subscriber Isolation

Why: Publishers shouldn't know (or care) who subscribes to their events. This loose coupling enables independent evolution and reduces coordination overhead.

✉️ Acknowledgement Flow

Why: Delivery confirmation isn't enough—publishers need to know if subscribers processed the event successfully. The acknowledgement flow provides end-to-end visibility.

🎨 SDK Over API

Why: While we provide REST APIs, the SDK abstracts away complexity (serialization, retry logic, error handling) to deliver the best developer experience.

🌍 Multi-Tenant by Design

Why: SignalWeaver is designed for multiple organizations to publish and subscribe independently. Publisher IDs and Subscriber IDs provide strong isolation boundaries.
