System Topology, eBPF Mesh & Distributed Sagas

Enterprise AI VeloGrid Architecture

A production-grade, modular architecture designed around 49 microservices (61 running pods) on Google Cloud GKE Autopilot (rbprj-100522). Unifying sidecarless eBPF networking, sub-millisecond event streaming, conversational voice AI pipelines, autonomous multi-agent swarms, and distributed lakehouse federation.

⚡ AI VeloGrid: Architectural Evolution (Phases 1 - 4)

A modern wrapper around your existing world. VeloGrid integrates legacy and modern applications with near-zero code changes. Complexity is shifted away from applications and into the infrastructure layer.
Phase 1: Legacy

Monoliths & SDKs

Heavy custom SDKs embedded directly inside application code. High coupling, slow build times, security patching friction, and distributed systems complexity burdened every dev team.

Overhead: High • Latency: Variable
Phase 2: Transition

Sidecar Proxies

Microservices offloaded TLS and routing to Envoy/Istio sidecars. Solved code coupling but introduced a heavy "sidecar tax" (+40MB RAM/pod, added network hops, and container lifecycle race conditions).

Overhead: Medium • CPU/RAM: +25%
Phase 3: Kernel Mesh

eBPF & NATS Mesh

Cilium eBPF in-kernel socket bypass eliminates sidecars. Transparent mTLS, L3/L4/L7 security, and NATS JetStream event mesh deliver <1ms inter-service communication without proxy overhead.

Overhead: Zero • Latency: <1ms
Phase 4: Current State

Autonomous Swarms & Lakehouse

Pipecat Voice WebRTC AI, Hive/Iceberg/Trino Lakehouse federation, Temporal durable sagas, and collaborative Multi-Agent swarms (Agno, CrewAI, LangGraph) on GKE Autopilot.

49 Services • 64 Pods • 100% Healthy

🔄 Mission-Critical Distributed Sagas & Workflows

Explore the exact operational lifecycles, compensation paths, and cross-service orchestration sequences:
Phase 1: Inbound SIP Ingress & SBC Transcoding Kamailio + RTPEngine + dSIPRouter
An incoming carrier emergency eCall or customer voice stream enters Kamailio SIP SBC. Kamailio signals RTPEngine to perform kernel-level zero-copy media transcoding from G.711/AMR to WebRTC DTLS-SRTP (OPUS).
Carrier Route: dSIPRouter Inbound Trunk | Transcoder: RTPEngine:22222
Phase 2: LiveKit SFU Real-Time Audio Streaming LiveKit WebRTC
Transcoded OPUS audio feeds directly into LiveKit WebRTC SFU server on port 7880. WebRTC data channels establish sub-50ms duplex streaming to the Pipecat Voice UI Kit and in-cab vehicle dashboard.
Audio Bitrate: 64kbps OPUS | Latency: <45ms
Phase 3: Pipecat Voice Pipeline & Gemini 3.7 Pro Inference Pipecat + LiteLLM + Gemini 3.7
Pipecat Voice Agent applies Silero VAD (Voice Activity Detection), streams audio to Deepgram STT, routes prompt tokens through LiteLLM to Gemini 3.7 Pro, and synthesizes neural audio with sub-300ms total conversational latency.
VAD: Silero | Gateway: LiteLLM:4000 | Model: gemini-3.7
Phase 4: NATS Event Mesh Signalling & Omnichannel Escalation NATS + Chatwoot CCaaS
Voice transcript events and intent extractions are published to NATS JetStream topic voice.sessions.events. If critical human assistance is requested, Chatwoot CCaaS seamlessly initiates live agent voice bridging.
NATS Topic: voice.sessions.events | Handoff: Chatwoot Omnichannel
Phase 1: OPA ABAC Authorization & OpenMetadata Masking OPA / Rego + OpenMetadata
Evaluates authorization for role FleetDispatcher to perform action book_parking. OpenMetadata tags dynamically trigger SHA-256 masking on driver telephone and national ID numbers for GDPR compliance.
Decision: ALLOW | Masking: SHA256_HASH
Phase 2: Real-Time Telemetry & Vector SOP Retrieval ClickHouse + Qdrant
ClickHouse queries vehicle speed (82.5 km/h) and DTC fault code P0299. Qdrant vector engine matches EU EC 561/2006 mandatory rest stop regulations and emergency workshop SOPs.
HOS Remaining: 34 min | Regulation: EC 561/2006
Phase 3: Multi-Agent Squad Collaborative Reasoning Agno + CrewAI + LangGraph + LiteLLM
Agno executes deterministic OBD-II diagnostics. CrewAI Lead Dispatcher plans optimal safe haven routing, while LangGraph manages stateful human-in-the-loop validation checkpoints via LiteLLM Gemini 3.7 Pro.
Model: gemini-3.7 | Safe Haven: HUB-A3-WUE Slot 18
Phase 4: Temporal Distributed Saga & Enterprise Execution Temporal + Twenty CRM + ERPNext + Chatwoot
Temporal Saga orchestrator acquires Redis distributed lock, settles payment, creates Twenty CRM dispatch task, books ERPNext maintenance work order, and delivers QR gate pass via Chatwoot CCaaS with automatic rollback compensation if any step fails.
Status: WORKFLOW_COMPLETED | QR Pass: QR-WUE-9821
Phase 1: Streaming Telemetry Ingestion & Benthos ETL Redpanda + Redpanda Connect
Vehicle CAN bus telemetry streams into Redpanda Kafka topic telematics.raw at 10,000 msg/sec. Redpanda Connect (Benthos) validates schemas, strips sensitive fields, and batches rows into Parquet files.
Throughput: 10k msg/sec | Format: Apache Parquet
Phase 2: Lakehouse ACID Storage & Hive Metastore Catalog MinIO S3 + Apache Iceberg + Hive Metastore
Parquet batches write directly to MinIO S3 Lakehouse (s3://lakehouse/telematics/). Apache Iceberg REST Catalog registers table snapshots, while Apache Hive Metastore synchronizes relational schemas for distributed engines.
Storage: MinIO S3 | Catalog: Hive Metastore (9083)
Phase 3: Trino Distributed Federated Query & DuckDB MCP Trino + Spark + DuckDB MCP
Trino executes federated SQL joins uniting Iceberg historical telematics with live Postgres CRM accounts and ClickHouse real-time sensor metrics in a single query with sub-second execution.
Query Latency: 340ms | Federation: Iceberg + Postgres + ClickHouse
Phase 4: dbt Core Lineage, OpenMetadata & Superset BI dbt Core + OpenMetadata + Superset
dbt Core models compile analytical transformations, verifying data quality tests and publishing end-to-end lineage into OpenMetadata. Self-service dashboards in Apache Superset and Redash refresh automatically.
Lineage: OpenMetadata (8585) | BI: Superset (8088)
Phase 1: Authentik OIDC / SAML Unified Authentication Authentik SSO
All platform users, fleet operators, and API keys authenticate through Authentik IAM with MFA and passkey support, issuing signed JWT tokens with granular role-based access claims.
Provider: Authentik (9000) | Token: OIDC JWT RSA-256
Phase 2: Cilium eBPF Kernel-Level Socket Bypass Cilium eBPF
Cilium intercepts TCP socket operations directly within the Linux kernel via eBPF sockops programs. Inter-service traffic bypasses traditional TCP/IP networking stack overhead, providing wire-speed throughput and transparent mTLS.
Kernel Hook: eBPF Sockops | Security: WireGuard mTLS
Phase 3: NeMo Guardrails & OPA Policy Enforcement NeMo + Open Policy Agent
AI agent prompts and tool outputs are scanned by NeMo Guardrails to block prompt injection and hallucinated schemas. OPA evaluates Rego policies to enforce zero-trust tenant isolation and data masking.
Rails: Jailbreak / PII Filter | Policy: OPA ABAC (8181)
Phase 4: Hubble Real-Time Kernel Flow Observability Hubble UI + Grafana Tempo
Cilium Hubble UI visualizes live L3/L4/L7 packet flows, DNS resolutions, and HTTP status codes directly from eBPF ring buffers, streaming OpenTelemetry traces to Grafana Tempo and Loki.
Flow Stream: Hubble eBPF (80) | Tracing: Tempo (3200)
