Serverless Cron Jobs on Cloudflare Workers (with Durable Objects)

Managing tasks on a scheduled basis has long been a staple of backend systems. Whether it’s clearing stale cache, syncing data with external services, or sending notifications, scheduled jobs — often referred to as cron jobs — are a vital tool. Traditionally, running cron jobs required a persistent server or virtual machine with a process scheduler. But thanks to the evolution of the cloud and edge computing, it’s now possible to run serverless cron jobs with ultra-low overhead and without managing infrastructure. Welcome to the powerful combination of Cloudflare Workers and Durable Objects. Read more

Monitor Core Web Vitals in CI/CD with GitHub Actions + Lighthouse

Website performance has become a critical aspect of modern development workflows. As search engines like Google prioritize user experience signals, websites are expected to load quickly, respond fluidly, and deliver consistent performance across devices. One set of metrics that underpin this philosophy is called Core Web Vitals. Monitoring these metrics early and often in your development pipeline can provide critical feedback to engineering teams—saving time, improving SEO, and guaranteeing a better user experience. In this article, we’ll look at how you can integrate Core Web Vitals monitoring into your CI/CD pipeline using GitHub Actions and Lighthouse. Read more

Kubernetes Cost Optimization for Small Teams on GKE

Managing Kubernetes clusters on Google Kubernetes Engine (GKE) can be both powerful and costly, especially for small teams with limited budgets and engineering resources. While GKE provides a managed and scalable Kubernetes experience with deep integration into Google Cloud’s ecosystem, it can quickly accumulate expenses if not properly optimized. Fortunately, there are practical strategies to help small teams maintain high efficiency while keeping infrastructure costs in check. Read more
