Kubernetes vs Single VM: Cost, Latency, and Deploy Speed Benchmarks
When deploying a web service, should you opt for the simplicity of a single Virtual Machine or the robust orchestration of a Kubernetes cluster? In this benchmark, we pit a single cloud VM against a three-node Kubernetes cluster using a lightweight HTTP API. We dive into the real-world trade-offs, measuring deployment times, tail latency under heavy load, and monthly infrastructure costs to help you architect the right environment for your needs.
How Naive Async/Await Chains Stall the Node.js Event Loop
Naive async/await use can silenty decimate Node.js performance by creating hidden waterfall chains. Each await serializes operations, blocking concurrency and forcing other requests to wait in line. This article explores why this stall happens at the microtask level and provides concrete code examples and benchmarks showing how to correctly use Promise.all to parallelize independent I/O. Unlock your system's full potential for higher throughput and lower latency.
