How it works
Code execution and runtime processing
Edge Functions Rust-based runtime processes JavaScript and TypeScript code directly at edge locations with zero cold starts.
The system automatically handles function instantiation and resource allocation across Azion's distributed infrastructure.
Advanced request routing directs traffic to appropriate function instances based on execution rules and geographic proximity.
Framework compatibility and development environment
The platform provides comprehensive support for modern frameworks including Next.js, Vue, React, Angular, Gatsby, and Astro.
Edge Functions provides comprehensive observability with execution traces and performance metrics for optimization.
The system supports WebAssembly execution, Node.js APIs, and WinterTC compatibility for flexible development.
Enterprise execution limits and platform integration
Edge Functions provides enterprise-grade execution limits with 5-minute CPU time and 20 MB application size for complex workloads.
Edge Functions executes within enterprise-grade compliant infrastructure, facilitating customer compliance processes with data protection and regulatory standards.
Local Edge SQL access enables ultra-fast data operations through NVMe-based storage, while Edge Storage integration supports file processing workflows.
Trusted by market leaders in banking, e-commerce, technology, and other industries.
