Technical Specifications
Cross-divisional architecture, data standards, security protocols, and deployment matrices for Aevum Zenth subsidiaries and integrated systems.
Scope & Governance
This document defines the baseline technical specifications, interoperability requirements, and compliance controls applied across all 400+ Aevum Zenth subsidiaries. Divisions may implement localized variations but must maintain alignment with core protocols to ensure seamless data exchange, security posture, and operational continuity.
- Applicability: All production, staging, and research environments under AZ corporate governance
- Audit Frequency: Quarterly automated compliance scans + biannual third-party penetration testing
- Override Authority: CTO Office & Divisional Architecture Review Board (DARB)
Versioning Strategy
Aevum Zenth follows Semantic Versioning (SemVer) 2.0.0 for all public APIs, SDKs, and infrastructure components. Internal microservices use a two-part versioning scheme (Major.Minor) with rolling deployments.
| Component Type | Version Format | Support Window | Deprecation Notice |
|---|---|---|---|
| Public APIs | MAJOR.MINOR.PATCH | 24 months per major | 90 days |
| Client SDKs | MAJOR.MINOR.PATCH | 18 months | 60 days |
| Internal Services | MAJOR.MINOR | 12 months (rolling) | 30 days |
| Infrastructure IaC | Git Tag + Commit SHA | Indefinite (immutable) | N/A |
Compute Tiers
Workloads are distributed across three standardized compute tiers. Divisional teams select tiers based on latency, throughput, and compliance requirements.
| Tier | Use Case | Max Latency | Runtime Environment | Orchestration |
|---|---|---|---|---|
| Core | Enterprise apps, data processing, ML training | < 50ms | Kubernetes (EKS/GKE/AKS), Docker | Helm + ArgoCD |
| Edge | IoT gateways, retail POS, field sensors | < 10ms | OpenYurt, K3s, Wasmtime | FluxCD + GitOps |
| Sovereign | ITAR/defense, classified research, air-gapped | Variable | On-prem bare metal, VM hardening | Terraform + Ansible |

All divisional networks converge through the Aevum Mesh Fabric (AMF), a zero-trust, SD-WAN backed overlay supporting mTLS, mutual authentication, and dynamic routing.
- Backbone: 400Gbps fiber interconnects across 62 countries
- Peering: Private ASNs with Tier-1 ISPs + satellite backup (LEO mesh)
- Isolation: VRF-lite segmentation per division + micro-segmentation per workload
- Monitoring: eBPF-based telemetry, Prometheus federation, Jaeger distributed tracing
Schema Formats
Data interchange mandates strict schema validation. All cross-divisional payloads must conform to the following standards:
| Format | Validator | Use Case | Encoding |
|---|---|---|---|
| JSON Schema 2020-12 | $ref + draft-2020-12 | REST APIs, config files | UTF-8 |
| Protobuf 3 | .proto definitions | gRPC, high-throughput internal | Binary |
| Apache Avro | Schema Registry | Kafka streams, data lakes | Binary + JSON fallback |
| XML Schema 1.1 | XSD 1.1 | Legacy banking, government compliance | UTF-8/UTF-16 |
Encryption Standards
All sensitive data at rest and in transit must utilize FIPS 140-3 validated cryptographic modules where applicable.
symmetric: AES-256-GCM | ChaCha20-Poly1305
asymmetric: ECC P-256 | X25519 | RSA-4096 (legacy only)
kdf: HKDF-SHA256 | Argon2id (passwords)
hashing: SHA-3-256 | BLAKE3 (performance)
sig: Ed25519 | ECDSA (P-256)
key_rotation: 90 days (automated via Vault/KMS)Authentication & Identity
Unified Identity Federation (UIF) manages cross-divisional access. MFA is mandatory for all privileged accounts.
- Protocol: OIDC 1.0 + OAuth 2.1 for clients, SAML 2.0 for enterprise SSO
- Tokens: JWT (RS256/EdDSA), short-lived (15min) + opaque refresh tokens
- Device Attestation: TPM 2.0 / Secure Enclave verification for edge/field devices
- Policy Engine: OPA (Open Policy Agent) with Rego rulesets per division
Compliance Matrix
| Framework | Scope | Technical Controls | Audit Method |
|---|---|---|---|
| ISO 27001:2022 | All divisions | Asset mgmt, risk assessment, IAM, logging | Automated + manual sampling |
| SOC 2 Type II | Cloud/SaaS products | Access control, change mgmt, monitoring | Third-party auditor |
| GDPR / CCPA | Consumer/HR data | Data minimization, DSR pipelines, encryption | DPO review + tooling |
| HIPAA | Health Sciences | BAA, audit logs, PHI tokenization | Quarterly penetration test |
| ITAR / EAR | Aerospace & Defense | Air-gap options, export control tagging | Export compliance board |
API Gateway
All external and cross-divisional API traffic routes through Gatekeeper v4, supporting rate limiting, payload validation, and dynamic routing.

Event Streaming
Divisional event buses converge into the Zenth Stream Fabric (ZSF), built on Apache Kafka with schema registry enforcement.
- Topics: Named per division/domain (e.g.,
energy.grid.events) - Retention: 7 days default, extendable to 365 days via governance request
- Consumers: Kafka Streams, Flink, or HTTP webhook relays
- Dead Letter Queue: Automatic retry (3x) then DLQ routing for manual inspection
