Technical Architecture

Enterprise-grade infrastructure powering 400+ subsidiaries across 62 markets. Cloud-native, zero-trust, and built for global scale.

Multi-Region Active-Active Kubernetes Orchestrated Event-Driven Microservices Zero-Trust Network
Core Principles

Engineering Foundations

Every system is designed with resilience, security, and interoperability at its core.

⚡
Horizontal Scalability
Stateless services with auto-scaling groups, designed to handle 10M+ concurrent requests without degradation.
🛡️
Zero-Trust Security
Mutual TLS, identity-aware proxies, and continuous micro-segmentation across all network boundaries.
🔄
Event-Driven Architecture
Asynchronous messaging with Kafka/Pulsar backplanes enabling loose coupling and real-time data synchronization.
📊
Observability First
OpenTelemetry-native tracing, distributed logging, and SLO-driven alerting across all service layers.
System Design

Layered Architecture

Modular, polyglot, and cloud-agnostic. Each layer operates independently with standardized contracts.

Deployment & Operations

CI/CD & Observability

GitOps-driven workflows with automated testing, progressive delivery, and full-stack telemetry.

Pipeline Workflow

01 Commit → Pre-commit Hooks (lint, fmt, secret scan)
02 Build → Multi-arch Docker images + SBOM generation
03 Test → Unit, Integration, Contract, Chaos engineering
04 Deploy → ArgoCD sync → Canary → Progressive rollout
05 Monitor → SLO validation → Auto-rollback on breach
argocd app sync zenth-core-api --revision main --strategy canary\nkubectl rollout status deployment/api-gateway\n✓ Deployment succeeded. SLO: 99.99% healthy
