Orchestration & governance

Coordinate agents and workflows with control

Where agent orchestration meets enterprise integration: long-running tasks, events, compensation, policy enforcement and auditability.

🧠

Supervisor, hand-off, fan-out, event-driven and workflow-led patterns, with a worked invoice example.

◈

Dependencies, retries, compensation, correlation IDs and event processing.

⏱

A2A task states, push notifications and MCP's tasks extension, mapped to asynchronous integration patterns.

✋

Approvals as separate, logged requests using MCP Multi Round-Trip Requests and A2A input-required.

🛡

Policy types, enforcement points, human approval, agent lifecycle and audit evidence.

⚠

Cascading failures, rogue agents and tool misuse, controlled in gateways and iFlows.

📊

OpenTelemetry trace context through agents, gateways and integration flows.

Patterns that carry over from classic integration

Agentic situation	Integration pattern
Several agents must finish one business process	Orchestrator or workflow-led backbone with A2A delegation, depth limits and budgets
Agent retries a write after a dropped stream	Idempotent receiver with idempotency keys
Step 3 of 5 fails after an agent posted documents	Saga with compensating actions
A2A task runs for hours	Asynchronous request-reply with correlation ID and status endpoint
Agent floods a backend with calls	Throttling, circuit breaker, bulkhead
Business event should wake an agent	Event-driven consumer via an event broker, not polling
High-impact action needs approval	Human task / approval step with timeout and escalation
