Temporal Cloud
Temporal durable workflow orchestration platform — run long-running, fault-tolerant workflows that survive process crashes, network failures, and infrastructure restarts with guaranteed exactly-once execution.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
mTLS for worker auth provides strong mutual authentication. Namespace isolation for multi-tenancy. SOC2 Type II certified. Workflow history encrypted at rest. GDPR compliant.
⚡ Reliability
Best When
Agent workflows involve multiple steps that must all complete, survive infrastructure failures, and maintain state across process restarts — especially multi-day or human-approval workflows.
Avoid When
Your tasks are simple, short-lived, and don't need durable state — the operational overhead of Temporal isn't justified for simple queues.
Use Cases
- • Orchestrating multi-step agent pipelines where each step must complete exactly once despite failures
- • Long-running agent workflows spanning hours or days — Temporal persists state without polling
- • Implementing saga patterns for distributed transactions with compensating actions on failure
- • Human-in-the-loop workflows — agents waiting days for human approval with Temporal signals
- • Agent job scheduling with complex retry logic, timeouts, and conditional branching
Not For
- • Simple short-lived tasks — use SQS or Cloud Tasks for fire-and-forget async jobs
- • Teams without Go, Java, Python, or TypeScript — Temporal SDKs cover these languages only
- • Ultra-low-latency real-time processing — Temporal adds workflow state overhead; use Kafka for streaming
Interface
Authentication
Temporal Cloud uses mTLS certificates for worker authentication plus API key for management operations. Namespaces provide multi-tenancy. Self-hosted Temporal supports various auth plugins.
Pricing
Temporal Cloud free credits allow significant testing. Self-hosted Temporal is free (MIT licensed). Action-based pricing means bursty workflows can have unpredictable costs.
Agent Metadata
Known Gotchas
- ⚠ Workflow code must be deterministic — no random numbers, current time, or external calls directly in workflow (use activities for these)
- ⚠ mTLS certificate management adds operational complexity for worker deployment vs simple API key auth
- ⚠ Temporal SDK versions must match server version — mismatches cause subtle failures
- ⚠ Workflow history grows unboundedly — use continue-as-new pattern for long-running workflows to reset history
- ⚠ Local activities run in-process and are faster but don't survive worker crashes — use regular activities for reliability
