Technical Specifications

Distributed System Design

Admin utilizes a microservices architecture deployed across multi-region Kubernetes clusters. Traffic is routed through an API gateway with intelligent load balancing and request throttling.

Client Layer

Web / Mobile / SDK

Edge & CDN

Cloudflare / WAF

API Gateway

Auth / Rate Limit / Routing

Core Services

Platform / Analytics / Automation

Data Layer

PostgreSQL / Redis / S3

Core Principles

Event-Driven: Asynchronous message passing via RabbitMQ for decoupled service communication
Stateless Compute: All application services are stateless, enabling horizontal scaling and zero-downtime deployments
Data Consistency: Eventual consistency model with distributed tracing and Saga pattern for complex transactions
Multi-Region: Active-active deployment across US-East, EU-West, and APAC regions with automatic failover

Technology Stack

Curated for reliability, performance, and developer velocity.

Layer	Technology	Version / Standard	Purpose
Frontend	TypeScript React 18	v18.2+	Isomorphic rendering, state management, component library
Backend API	Go / Node.js	1.21+ / 20+	High-throughput services, I/O heavy tasks
Database	PostgreSQL	v15 (Citus Extension)	Primary relational storage, distributed queries
Caching	Redis	v7 Cluster Mode	Session storage, rate limiting, real-time pub/sub
Message Queue	RabbitMQ	v3.12	Event streaming, background job processing
Infrastructure	Kubernetes / Terraform	v1.28 / v1.6	Container orchestration, IaC provisioning

Observability	Prometheus / Grafana / ELK	Latest	Metrics, logging, distributed tracing (Jaeger)

API & Integration Specifications

Admin exposes a versioned REST API with GraphQL support for complex queries. All endpoints require authentication via OAuth 2.0 or JWT tokens.

Base URL

https://api.admin.io/v3

Authentication

Bearer Token / OAuth2

Rate Limiting

1,000 / 10,000 req/min

Standard / Enterprise tiers

Data Format

JSON / GraphQL
