Technical Specifications

📋 Platform Overview

Aevum Encyclopedia is built on a microservices architecture designed for massive scalability, high availability, and sub-50ms response times globally. The platform serves over 2.4 million knowledge articles across 140+ languages.

Core Technologies

• Backend: Go (Golang) + Rust microservices on Kubernetes
• Database: CockroachDB (distributed SQL) + Elasticsearch + Redis
• AI Engine: Custom transformer models (Aevum-LLM-7B, fine-tuned BLOOM architecture)
• CDN: Multi-CDN strategy (Cloudflare, Fastly, AWS CloudFront)
• Message Queue: Apache Kafka (event sourcing) + NATS (real-time)
• Search: Elasticsearch 8.x + Meilisearch (semantic/vector search)
• Frontend: Next.js 14 (App Router) + TypeScript + Tailwind CSS
• Infrastructure: Terraform + Pulumi across 3 cloud regions

🏗️ System Architecture

The platform follows an event-driven microservices pattern with CQRS (Command Query Responsibility Segregation) for optimal read/write performance.

☁️ Infrastructure

Aevum Encyclopedia operates across three geographic regions with active-active failover and automatic traffic shifting.

🔗 API Endpoints

All API endpoints are served from api.aevum-encyclopedia.com with TLS 1.3. Both REST and GraphQL interfaces are available.

Example: Article Request

curl -X GET "https://api.aevum-encyclopedia.com/v4/articles/quantum-computing" \n  -H "Accept: application/json" \n  -H "Accept-Language: en-US" \n  -H "X-API-Key: $AEVUM_API_KEY"

🔐 Authentication

Aevum Encyclopedia supports multiple authentication methods depending on the access tier and use case.

API Key Usage

Authorization: Bearer sk_aevum_live_4f8b2c...a1e7d9
X-API-Key: ak_aevum_live_3d7e9f...b2c4a8

⏱️ Rate Limiting

Rate limits are enforced per API key and follow a sliding window algorithm with automatic burst allowance.

Rate Limit Headers

Every API response includes rate limit metadata in headers:

X-RateLimit-Limit: 1000
X-RateLimit-Remaining: 847
X-RateLimit-Reset: 1705334400
Retry-After: 30  // Only present when rate-limited

📄 Data Formats

Articles and metadata are served in multiple formats to support various integration scenarios.

Article Content Model

interface Article {
  id: string;                // Slug-style identifier
  title: string;
  abstract: string;          // Max 500 characters
  content: ArticleSection[];  // Structured sections
  metadata: ArticleMetadata;
  references: Reference[];
  categories: string[];
  language: string;           // BCP 47 tag
  ai_insights?: AIInsights;
  verification: Verification;
}

interface Verification {
  score: number;             // 0.0 - 1.0
  reviewers: number;
  last_reviewed: string;     // ISO 8601
  tier: "bronze" | "silver" | "gold";
}

⚡ Performance Benchmarks

Measured at the 95th percentile (p95) over a 30-day rolling window across all regions.

Endpoint Latency Breakdown

📈 Scalability

The platform auto-scales horizontally based on custom metrics including request rate, CPU utilization, and queue depth.

💾 Caching Strategy

Multi-tier caching ensures sub-5ms response times for cached content at the edge.

🛡️ Security Model

Security is implemented at every layer of the stack, from edge to database.

✅ Compliance

🔒 Encryption

📦 SDKs & Libraries

Official client libraries are available for the most popular programming languages.

Quick Start — JavaScript

import { AevumClient } from '@aevum/sdk';

const aevum = new AevumClient({
  apiKey: process.env.AEVUM_API_KEY,
  region: 'us-east-1',
  timeout: 5000,
  retries: 3,
});

// Fetch an article
const article = await aevum.articles.get('quantum-computing');
console.log(article.title);        // "Quantum Computing"
console.log(article.word_count);   // 8420
console.log(article.verification.score); // 0.997

// Semantic search
const results = await aevum.search.semantic({
  query: 'How do quantum computers solve NP-complete problems',
  limit: 10,
  min_relevance: 0.85,
});

🪝 Webhooks

Subscribe to real-time events for article updates, new content, and system notifications.

Webhook Signature Verification

import { createHmac } from 'crypto';

function verifyWebhook(payload: string, signature: string, secret: string) {
  const expected = createHmac('sha256', secret)
    .update(payload)
    .digest('hex');
  
  return createHmac('sha256', secret)
    .update(payload)
    .digest('hex') === signature;
}

// Webhook headers:
// X-Aevum-Signature: sha256=<signature>
// X-Aevum-Timestamp: <unix_ms>
// X-Aevum-Event: article.created
