Technical Brief
Enterprise architecture, infrastructure standards, and integration specifications for the Aevum Zenth multidivisional platform.
System Overview
The Aevum Zenth technical ecosystem operates as a unified, multi-tenant enterprise platform supporting 400+ subsidiaries across 62 jurisdictions. The architecture follows a distributed microservices model with event-driven communication, standardized data governance, and zero-trust security boundaries.
Architecture Topology
The platform utilizes a polyglot microservices architecture orchestrated across hybrid cloud regions. Communication follows strict protocol boundaries:
- Internal Services: gRPC over mTLS (port 443/8443) with Protobuf v3
- Event Bus: Apache Kafka cluster (multi-AZ, min 5 brokers) with schema registry (Avro/Protobuf)
- External APIs: REST/GraphQL via API Gateway (Kong/Envoy) with rate limiting & WAF
- Data Sync: CDC pipelines (Debezium) → Event Sourcing → Read Models
Core Technology Stack
| Layer | Technology | Version/Standard |
|---|---|---|
| Runtime | Go, Java 21, Rust, Node.js 20+ | LTS / Stable |
| Containerization | Docker / containerd | OCI v1.1 |
| Orchestration | Kubernetes (EKS/GKE/AKS) | v1.28+ |
| Primary DB | PostgreSQL / TimescaleDB | 15.4+ |
| Caching | Redis Cluster / Memcached | 7.2+ |
| Message Queue | Apache Kafka / NATS | 3.6+ |
| CI/CD | ArgoCD + GitHub Actions | GitOps |
| IaC | Terraform / Pulumi | TF 1.6+ |
Infrastructure & Deployment
Global deployment spans 9 primary regions with active-active failover. Infrastructure is provisioned via GitOps and follows immutable infrastructure principles.
Disaster recovery follows RTO < 15min / RPO < 5min standards. Cross-region replication is asynchronous with conflict resolution via vector clocks.
Security & Compliance
All systems adhere to Zero Trust Architecture (ZTA) principles. Identity is managed via centralized IAM with fine-grained RBAC/ABAC policies.
- Authentication: OAuth 2.0 / OIDC, SAML 2.0, MFA (FIDO2/WebAuthn)
- Encryption: AES-256-GCM at rest, TLS 1.3 in transit, mTLS for service mesh
- Secrets Management: HashiCorp Vault with dynamic credentials & auto-rotation
- Compliance: SOC 2 Type II, ISO 27001, GDPR, CCPA, HIPAA, PCI-DSS L1
- Audit: Immutable event logging (WORM storage), 7-year retention
API & Integration Framework
All external and cross-divisional communication routes through the Aevum API Gateway. Standard OpenAPI 3.1 specifications are enforced. SDKs are available for Go, Python, Java, and TypeScript.
// Standard event ingestion payload

}Rate limits: 10,000 req/min (standard), 50,000 req/min (enterprise). Exceeding thresholds triggers 429 responses with Retry-After headers.
Performance SLAs
| Metric | Target | Measurement Window |
|---|---|---|
| API Availability | 99.99% | Monthly rolling |
| p95 Latency | < 120ms | Real-time / 5-min buckets |
| p99 Latency | < 350ms | Real-time / 5-min buckets |
| Error Rate (5xx) | < 0.05% | Rolling 24h |
| Data Replication Lag | < 2s | Continuous |
SLA credits are calculated monthly per division. Monitoring is handled via Prometheus + Grafana with custom alerting rules routed to PagerDuty/OpsGenie.
Technical Support & Incident Response
Platform engineering and SRE teams maintain 24/7 coverage. Incident severity levels follow standard ITIL/SRE practices:
- SEV-1: Critical outage (response < 15min, resolution < 2h)
- SEV-2: Major degradation (response < 30min, resolution < 4h)
- SEV-3: Minor issue / workaround available (response < 2h, resolution < 24h)
- SEV-4: Enhancement / low-impact bug (response < 24h, resolution per roadmap)
