Deploy Enterprise Quorum

Strict Hard Cap (max_vcpu Anti-Exploit Enforcement)

To prevent enterprise organizations from evading higher-tier licensing by horizontally chaining basic low-tier nodes, each tier enforces a strict hardware ceiling (max_vcpu). The VastarIPShield Enclave Daemon directly inspects hardware CPU topology (/proc/cpuinfo & cryptographic attestation receipt). Any node or cluster exceeding its tier cap will be blocked from decrypting the container image until an upgrade is completed.

✓✓ Clustered Scheduler
PostgreSQL firing authority, Native Admission Bridge outbox, immutable runtime pins, DST fold policy, bounded catch-up, multi-tenant budget backpressure, & clock skew incident fencing
◐ Polling / Interval

◐ Cloud iPaaS
Extensive cloud enterprise connectors, but high cloud latency (200ms–1500ms) without zero-copy streaming for local SCADA/factory telemetry
◐ gRPC Workers
Workflow ingress exclusively via gRPC client SDKs; Kafka/MQTT/OPC-UA ingestion requires custom developer-built workers outside engine

Hardware-grade MicroVM / LXC sandbox with isolated memory, CPU limits, and seccomp filters
◐ Cloud Multi-Tenant
Custom Ruby/Python code steps execute in Workato managed cloud worker pool
Code (Self-Hosted)
Sandbox and host security must be implemented manually by customer in worker code
◐ External Worker
Executed outside Zeebe cluster; security isolation relies on customer worker environment
◐ Container Pod
LangGraph Cloud runs in container pods; custom sandboxing requires custom infrastructure
◐ Node vm2 / Worker
JavaScript vm2 sandbox or external task runners; historically prone to VM escape CVEs

◐ Self-Hosted Cluster
Self-hostable in private VPC; customer responsible for enclave architecture and KMS integration
◐ Self-Managed K8s
Deployable to private Kubernetes; confidential computing must be handled at the node pool level
— Cloud SaaS / K8s
LangSmith Cloud hosts telemetry and traces; self-hosted enterprise requires full Kubernetes cluster
◐ Self-Host Docker
Self-hostable on customer VM; no native cryptographic enclave attestation or KMS envelope sealing
Multi-Cloud & Edge Compute Portability

Run workflows at the edge, private cloud, AWS, GCP, Fly.io, or on-premise hardware

Hashing Vault API Key + pemfilteran egress deterministik + anti prompt-leakage
✓ Encrypted Vault
Enterprise encrypted credential vault with role-based secret masking
Code-Defined
Secrets managed directly within customer worker application code (self-managed KMS)
✓ Cluster Secrets
Zeebe cluster secret management and encrypted environment variables

✓✓ User Tasks
Native BPMN User Tasks integrated with Camunda Tasklist application
✓ Interrupt Logic
Native interrupt() mechanism in state graphs for human-in-the-loop approvals
◐ Wait Webhook
Wait node with webhook callback URL for basic manual approval gates
Cryptographic Version Digest Pinning (Zero Drift)

Immutable cryptographic digest pinning (SHA-256) across workflows, rules, and agents

✓✓ Immutable SHA-256
Permanent SHA-256 cryptographic digest locks across workflows, vRules, AI prompts, and sidecars
✓ Version History
Recipe version history with phased release lifecycle (Dev/Test/Prod environments)
✓ Code Versioning
Workflow versioning via explicit code patch API (workflow.getVersion)
✓ Semantic Version
Process definition keys with incremental semantic versioning
Code (Git)
Git commit deployment revisions in LangSmith Platform
◐ Basic History
Basic workflow version history (no cryptographic digest locks)
Signed Terminal Provenance (Ed25519) & Journal Governance

Cryptographically signed execution receipts (Ed25519 canonical envelope v1.3) with multi-storage journal governance (PostgreSQL / TiKV / Cloudflare DO)

✓✓ Signed Ed25519 Provenance
Cryptographically signed receipts (AiVRuleDecisionReceiptV1, Ed25519 24-tuple envelope) with KMS attestation & multi-backend journal governance
◐ Activity Logs
Standard recipe execution audit logs & role-based activity trails (no cryptographic signatures)
✓ Event History
Tamper-evident deterministic event history replay log
◐ Event Streams
Elasticsearch/OpenSearch event stream & Optimize audit reports (no cryptographic sealing)
— Tracing Spans
LangSmith tracing spans (application observability, not cryptographically sealed sovereign audit)
— Execution Logs
Standard execution logs in database without cryptographic signatures or tamper-proof receipts
Pricing Model & Total Cost of Ownership (TCO)

Predictable flat server compute cost vs punitive per-execution / per-task fees

✓✓ Pure BYOC /vCPU
100% Pure Sovereign BYOC via VastarIPShield • Starts at $3/vCPU (Orch) + $2/vCPU (Shield) • vFlow 1-vCPU TCO ~$9.50/mo • UNLIMITED runs • Strict max_vcpu caps
— Punitive Task Tax
Base license $10,000 – $50,000+/yr PLUS metered per-task quota that rapidly inflates with volume
◐ Actions / Compute
Temporal Cloud bills per Million Actions + storage, or complex self-managed DevOps infrastructure costs
◐ Metered Instances
Tiered metered pricing per task execution / process instance volume
◐ Step & Token Fee
Metered fee per node step execution in LangSmith + LLM token overage fees
◐ Punitive Run Caps
Strict execution caps (2.5k–10k runs/mo on Starter/Pro plans) forcing repeated tier upgrades

Deterministic, Governed Workflow Contracts

No black-box magic. The canonical VastarOrch orchestration contract (vastarorch.workflow/v1) seamlessly ties together ingress triggers, AI Agent invocations (ao.activity.ai.agent.*), policy guardrail checks (ao.activity.governance.policy.*), human approval gates, and critical connector executions (ao.activity.connector.*) with complete mathematical determinism on the vFlow core.

  • 100% real-time bidirectional synchronization with VastarOrch Studio Visual Canvas
  • Zero schema drift via cryptographic SHA256 version digest pinning
  • Immutable audit journal signed by Ed25519 terminal provenance keys
