The Migration of Legacy Applications to Workers

What this post added

This post details the migration of legacy applications to Cloudflare Workers. It outlines the benefits of migrating from legacy platforms to serverless, including instant scaling, reduced maintenance, and enhanced security. The migration process is demonstrated using a Node.js application, showing how to replace the Node.js HTTP module with Workers' Service Workers API and directly port business logic. Key Cloudflare technologies used include Workers for serverless compute, Wrangler for developer tooling, Access for zero-trust security, and Argo Tunnels for secure origin connectivity. The post also highlights a 'quick win' by adding zero-trust security to an existing application before migrating the compute.
