Cloudflare Workers scale too well and broke our infrastructure, so we are rebuilding it on Workers

What this post added

This post details how DevCycle rebuilt its event pipeline on Cloudflare Workers to handle instantaneous load spikes that overwhelmed their traditional AWS infrastructure. It highlights the challenges of scaling traditional cloud services versus the inherent scalability of Workers, and outlines the architectural shift to a Worker-based event ingestion system using Kinesis Data Firehose to S3, with future plans for Cloudflare Queues and R2. It also discusses best practices for architecting applications with Workers, emphasizing data locality and the use of Cloudflare's data services (KV, Durable Objects, R2, D1).
