Scaling Node.js Applications to Millions of Users: A Practical Guide

Key Takeaways Leverage Node.js strengths: Its single-threaded, non-blocking I/O makes it ideal for handling massive concurrency, but scaling requires deliberate strategies. Go horizontal, not just vertical: Scaling to millions of users demands clustering, load balancing, and stateless architecture across multiple servers. Cache aggressively: Use Redis, Memcached, and CDNs to reduce latency, offload databases, and serve…

Analyzing Performance Improvements of AI Models Using Wasm at the Edge

TL;DR: WebAssembly (Wasm) lets you ship the same AI inference module across wildly different edge devices, with strong sandboxing and near-native speed when using SIMD + threads. Below is a minimal setup to measure latency, throughput, memory, and cold-start across: Native CPU inference (onnxruntime-node) Wasm CPU inference (onnxruntime-web running via WebAssembly + SIMD + threads)…

Automating SBOM Generation and Vulnerability Analysis

What is SBOM? SBOM (Software Bill of Materials) = the ingredient label of software.It lists all parts *(open-source libraries, frameworks, dependencies, versions, licenses) * that make up an app or system. Real-Life Example Think of food packaging: you buy bread, and the label says “contains wheat, soy, nuts.” In software, SBOM is that label: “contains…
