Localized Deployment Architecture Solution for Aviation Communication System

System Localized Deployment Architecture Solution

Adopting localized private deployment, the business system, communication records (including audio/video), model files, and log audit data are all hosted within the client's intranet, ensuring core data is independently controllable without relying on any public network APIs.

(1) Overall Architecture: B/S unified WEB portal + microservices containerized (Kubernetes/K8s) deployment. The system is layered into "Access Layer / Service Layer / Data Layer / Operations Layer":

• Access Layer: Load Balancer (LB) + domestic firewall/WAF + API gateway, providing unified entry, authentication, rate limiting, and auditing.

• Service Layer: Communication services, user authentication, speech transcription, recording storage, message push, emergency command, and other microservices are split by business domain, supporting independent scaling and canary releases.

• Data Layer: Domestic distributed database cluster + object storage (audio/video/recordings) + log search (full-text search/distributed tracing), enabling categorized storage and unified management.

• Operations Layer: Prometheus+Grafana monitoring and alerting, SkyWalking full-link tracing, CI/CD with private image registry, enabling early fault detection and resolution.

(2) High Availability and Disaster Recovery: Deployed in a "two sites, three centers" architecture (Beijing production center, Nanjing production center, remote disaster recovery center). Key components support redundancy and failover; business interruption risks are controllable.

(3) Network Zoning and Security: DMZ zone / application zone / data zone are isolated; least privilege and whitelist-based access; transport encryption, storage encryption, and audit trails; compliant with Xinchuang (domestic IT innovation) and data security requirements.
