I've been working on Brewly Store, a coffee subscription service, and recently decided to tear down our traditional setup to embrace a more modern, edge-first architecture.</strong><br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Feq184jhv53ei492cxt8x.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Feq184jhv53ei492cxt8x.png" alt=" " width="800" height="400"></a><br> </p> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__body flex items-center justify-between"> <a href="https://brewly-frontend.pages.dev/" rel="noopener noreferrer" class="c-link fw-bold flex items-center"> <span class="mr-2">brewly-frontend.pages.dev</span> </a> </div> </div> </div> <p><strong>The Tech Stack 🛠:</strong></p> <p>Runtime: Cloudflare Workers (using the Hono framework).</p> <p>Language: TypeScript.</p> <p>Infrastructure: AWS EKS for core services.</p> <p>Delivery: A full GitOps pipeline using ArgoCD and GitHub Actions.</p> <p>Why the Migration?<br> We moved from a containerized AWS ECR setup to Cloudflare Workers. Why?</p> <p>Latency: Moving logic closer to the user.</p> <p>Scalability: Handling subscription spikes without managing scaling groups.</p> <p>Developer Experience: Hono provides a lightweight, expressive way to handle routing that feels incredibly fast.</p> <p>The Security-First Mindset 🔒:<br> As a DevOps specialist, I believe infrastructure is only as good as its security. For Brewly, I’ve implemented:</p> <p>GPG-signed commits to ensure the integrity of our code.</p> <p>Strict secret management using tools like Kleopatra and PwPush.</p> <p>GitOps-driven deployments where ArgoCD ensures the cluster state matches our repository exactly.</p> <p><strong>Lessons Learned from the Trenches:</strong><br> The biggest challenge wasn't the code—it was the shift in thinking from "servers" to "distributed functions." Debugging edge cases in a serverless environment requires a robust observability stack, which we are currently refining within our EKS cluster.<br> </p> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__cover"> <a href="https://www.youtube.com/@devopseng" class="c-link align-middle" rel="noopener noreferrer"> <img alt="" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fyt3.googleusercontent.com%2FfKKUnpAd3y9pScxLrZS41AiKqwnvWlOsRm-dRhzviopMBg17y_EODownVf5D-A0tWH4nU40TRRs%3Ds900-c-k-c0x00ffffff-no-rj" height="900" class="m-0" width="900"> </a> </div> <div class="c-embed__body"> <h2 class="fs-xl lh-tight"> <a href="https://www.youtube.com/@devopseng" rel="noopener noreferrer" class="c-link"> DevOps Journey UA - YouTube </a> </h2> <p class="truncate-at-3"> Welcome to the channel! I'm Alex, a DevOps Specialist. On this channel, I share hands-on experience in building modern IT infrastructure, automation, and implementing BigTech standards in real-world projects. What to expect: Cloud Solutions: Deep dives into AWS (EKS, ECR, Secrets Manager) and transitioning to Serverless architecture (Cloudflare Workers, D1). Containerization: Everything about Docker, Kubernetes, and CI/CD pipeline optimization. Security First: Practical advice on secret management, GPG-signed commits, and infrastructure security. IT Productivity: Reviews of task managers (Jira, Linear, ClickUp) and building effective workflows for developers. Why subscribe? I don't just talk about theory—I show the "end-to-end" process: how to migrate a real service from AWS to Cloudflare, how to set up automated NAS backups, or how to organize a team's work in Jira. All content is based on my daily work with Linux (Ubuntu) and CLI-driven environments. </p> <div class="color-secondary fs-s flex items-center"> <img alt="favicon" class="c-embed__favicon m-0 mr-2 radius-0" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fwww.youtube.com%2Fs%2Fdesktop%2F5af4fee3%2Fimg%2Ffavicon.ico" width="48" height="48"> youtube.com </div> </div> </div> </div> ai webdev programming devops
