Azion Technology Intelligence

What is Azion?

Azion is a Brazilian edge computing platform providing CDN, serverless computing, security, and application delivery services. Founded in 2011 in Porto Alegre, Azion has grown to serve major Latin American enterprises while expanding globally with edge locations across the Americas, Europe, and Asia.

Azion's edge platform runs applications closer to end users, reducing latency and improving performance. Their Edge Functions execute JavaScript or WebAssembly at edge nodes, similar to Cloudflare Workers. The platform emphasizes security with built-in WAF, DDoS protection, and bot management.

Major Brazilian companies including Magazine Luiza, Pague Menos, and media outlets rely on Azion. The platform is particularly strong for Latin American deployments with extensive Brazilian, Argentine, and Chilean edge presence.

Azion Platform Features

Edge Functions: Serverless JavaScript execution at edge locations. Process requests, modify responses, implement authentication without origin round-trips. Supports Deno-compatible APIs.

Edge Application: Reverse proxy with advanced caching rules, load balancing, and content optimization. Image processing (resize, format conversion) at edge.

Edge Firewall: WAF with OWASP Top 10 protection, rate limiting, and geo-blocking. Custom rules engine for application-specific security policies.

DDoS Protection: Always-on volumetric attack mitigation. Layer 3/4/7 protection. BGP-based scrubbing for large-scale attacks.

Real-Time Metrics: Live analytics on traffic, security events, and performance. Data available within seconds for rapid debugging.

Edge SQL: Distributed SQLite databases replicated across edge locations. Read replicas everywhere, write to primary. Sub-millisecond reads.

Azion Use Cases

Latin American E-commerce: Brazilian retail giants use Azion for fast page loads, image optimization, and security during peak sales like Black Friday. Edge locations throughout Brazil ensure low latency.

Media Streaming: Brazilian TV networks and streaming services deliver video through Azion's CDN. Live event streaming with real-time encoding at edge.

Financial Services: Banks and fintechs use Azion's security stack for PCI compliance. Bot protection prevents credential stuffing on banking portals.

Gaming: Game asset delivery and API acceleration. Edge Functions handle authentication and matchmaking logic close to players.

API Acceleration: Cache API responses at edge. Transform data formats. Implement rate limiting and authentication without origin load.

Static Site Hosting: JAMstack deployments with edge functions for dynamic features. Global distribution with Brazilian PoP advantage.

Azion Edge Functions

A/B Testing at Edge

async function handleRequest(request) {
    const url = new URL(request.url);

    // Get or assign variant
    const cookies = request.headers.get('Cookie') || '';
    let variant = cookies.match(/ab_variant=(\w)/)?.[1];

    if (!variant) {
        variant = Math.random() < 0.5 ? 'A' : 'B';
    }

    // Route to variant origin
    const origin = variant === 'A'
        ? 'https://origin-a.example.com'
        : 'https://origin-b.example.com';

    const response = await fetch(origin + url.pathname, request);
    const newResponse = new Response(response.body, response);
    newResponse.headers.append('Set-Cookie', `ab_variant=${variant}; Path=/`);

    return newResponse;
}

Image Optimization

// Resize images based on device
async function handleRequest(request) {
    const width = request.headers.get('Sec-CH-Viewport-Width') || '1920';
    const optimizedUrl = `${request.url}?width=${width}&format=webp&quality=80`;
    return fetch(optimizedUrl);
}
