¶ Orchestration in eTag Fuse
Orchestration is the coordination of multiple systems, services, tasks, decisions, and users into a unified, stateful process. It builds on integration and automation to enable adaptive, rule-based, multi-step execution across domains.
In Fuse, orchestration is a core engine that gives your logic structure, resilience, and intent — all while remaining composable and cross-domain aware.
¶ 1. What is Orchestration?
Orchestration is how Fuse enables:
Multi-step process coordination
Human-in-the-loop interaction
State tracking, delay handling, compensation
Policy- and identity-aware routing
AI, data, and service participation in structured flows
Orchestration ensures that systems do the right thing, at the right time, in the right context.
¶ 2. Orchestration vs. Automation
Whereas automation handles individual actions, orchestration defines how those actions relate and flow together.
| Feature |  Automation |
Orchestration |
|---|---|---|
| Scope | Single task or event | End-to-end multi-step process |
| Flow Logic | Triggered reaction | Stateful execution path |
| Actors | One system or trigger | Many systems, services, users, and policies |
| Fuse Component | Pipelines, Rules, Triggers | Workflow Engine, Flow Manager, Compensation |
Orchestration is how you compose intelligence, routing, and control across everything else.
¶ 3. Core Orchestration Capabilities in Fuse
Fuse includes a full orchestration engine with:
Parallel and sequential execution
Human-in-the-loop steps
Timeouts, delays, and retry logic
Decision gateways and policy-based routing
State versioning, auditability, and re-entry support
Rollback and compensation for failed steps
All orchestrations are visualized through a low-code flow designer and are fully observable with logs, traces, and metrics.
¶ 4. Examples of Orchestration in Fuse
Real-world orchestration use cases include:
¶ 
Tax Refund Workflow
- Validate input
Check fraud Create bank account Notify taxpayer Generate logs
¶ 
Satellite Data Relay
- Capture telemetry Run AI model Enrich Route event Push to ground station
¶ AI Decision Process
- Preprocess Model A Decision Human approval (if confidence low) Notify + store outcome
These involve sequencing, roles, branching, and auditability — orchestration territory.
¶ 5. Domain-Aware Orchestration
What makes Fuse orchestration powerful is that it’s cross-domain by design. You can:
Orchestrate integrations (API calls, file drops, data events)- Trigger automations (pipelines, policy enforcement)
Use security tokens to branch logic based on user role or risk- Invoke AI models as part of decision-making
Route to UI forms or dashboards for user interaction
Apply compliance policies dynamically mid-flow
Orchestration lets all of Fuse's domains collaborate intentionally.
¶ 6. Human-In-The-Loop Orchestration
Fuse includes built-in orchestration steps that wait for or depend on human decisions:
Approvals and rejections
Record reviews and comments
Form-based data entry or updates- Escalation and reassignment paths
You define who, when, and why a human must act — with full control over roles, UI, and fallback behavior.
¶ 7. Orchestration as the Bridge to Interoperability
If integration connects and automation reacts, orchestration adds:
Structure- Intent
- Flow
Adaptability
It’s how Fuse turns isolated triggers into intelligent, coordinated, policy-aware processes.
Orchestration is the gateway to Interoperability — where systems collaborate with meaning, traceability, and shared context across every domain.
