¶ Orchestration Layer
The Orchestration Layer in Fuse coordinates complex, multi-step workflows — combining humans, systems, AI, security policies, and services into governed, stateful processes.
Orchestration brings structure, resilience, and explainability to how actions, decisions, and domains interact.
¶ Overview
Orchestration refers to the intentional coordination of:
Systems and integrations
Human-in-the-loop decisions
AI reasoning and outputs
Security enforcement and access policies
External services and event sources
Where automation executes individual tasks, orchestration defines how tasks, decisions, and actors flow together across domains.
¶ Key Capabilities
- Visual Workflow Modeling — Low-code designer for multi-step flows
- Stateful Execution Paths — Track workflow state, retries, escalations, and decisions
- Parallel and Sequential Processing — Coordinate concurrent or dependent activities
- Human-in-the-Loop Interaction — Approvals, task completions, escalations, and reassignments
- Timeouts and Delays — Handle waiting periods, expirations, and retries natively
- Policy and Risk Enforcement — Insert dynamic gates, step-up auth, and compliance checkpoints
- Compensation and Rollback — Recover or undo partial workflows upon failure
- Auditability and Observability — Full logs, metrics, and step traceability
Fuse orchestrations are:
Domain-aware — Compose across Security, Intelligence, Workflow, Messaging, Storage, and more
Governed — Apply scoped tokens, runtime context, and policy decisions during flow- Composable — Reuse steps, subflows, and logic templates
¶ Orchestration vs Automation
| Feature | Automation Layer | Orchestration Layer |
|---|---|---|
| Scope | Single task or reaction | Multi-step, governed, stateful execution |
| Actors | Systems, pipelines, events | Systems, humans, AI agents, security tokens |
| Complexity | Low to moderate | Moderate to very high |
| Example | Auto-send email on form submission | Approve refund workflow with human + AI steps |
Automation executes tasks —
Orchestration coordinates tasks, decisions, humans, AI, and policies.
¶ Real-World Orchestration Examples
Refund Workflow — Validate claim, detect fraud risk, route high-risk cases to human review, notify outcome- Telemetry Orchestration — Collect IoT signals, enrich via AI model, trigger cross-region data routing
- AI Decision Loop — Model scoring ? low-confidence escalation ? supervisor approval ? audit capture
Each orchestration operates with full visibility, policy enforcement, and cross-domain composability.
¶ Domain-Aware Orchestration in Fuse
Orchestrations are not limited to one domain — they span across:
- Integration Layer — Initiate flows from external system events
- Automation Layer — Trigger reusable actions and pipelines within flows
- Security Domain — Gate flows based on identity, risk, or session trust
- UI Domain — Drive human approvals, task completion, and form input
- Messaging Domain — Send and track notifications as part of the flow
- Intelligence Domain — Invoke AI decision points mid-orchestration
Fuse orchestrations are designed for modular, explainable domain coordination.
¶ When to Use Orchestration
Use the Orchestration Layer when you need:
- Human + system + AI interaction inside the same process
- Dynamic decision routing based on runtime context
- Long-running, retryable workflows across multiple domains
- Governed approvals, escalations, and fallback behaviors
- Full audit trails of actions, decisions, and access scopes
If you only need to react to simple events or trigger a single task, use:
