When working with large models from Hugging Face—whether it’s image generation, text-to-image synthesis, or other AI tasks—you need robust infrastructure that handles: Scalability: Auto-scaling to handle variable loads from 0 to thousands of concurrent requests Cost Efficiency: Paying only for what you use while maintaining performance Reliability: 99.9%+ uptime with proper error handling and monitoring Security: Protecting models, data, and API endpoints Observability: Comprehensive logging, metrics, and tracing This comprehensive guide demonstrates how to deploy a Hugging Face model to AWS using infrastructure as code (CDK with TypeScript), combining SageMaker for model hosting and Lambda for API orchestration.https://yennj12.js.org/yennj12_blog_V4/posts/building-serverless-url-shortener-aws-cdk/Sun, 10 Aug 2025 15:55:00 +0800https://yennj12.js.org/yennj12_blog_V4/posts/building-serverless-url-shortener-aws-cdk/Deep dive into designing and building a production-ready URL shortener using AWS serverless services, exploring architectural tradeoffs, and implementing with AWS CDK.
