Migrate a Rails App from Heroku to Render

The article provides a detailed guide on migrating a Ruby on Rails application from Heroku to Render, using the git-scm.org site as a practical example. It outlines the benefits of Render, such as free private networking and DDoS protection, and explains key differences between Heroku and Render, particularly in terms of infrastructure management and application architecture. The process involves creating a render.yaml file to define and integrate components like Web Services, PostgreSQL databases, Redis for caching, and Cron Jobs for scheduled tasks, emphasizing the use of environment variables to securely manage sensitive information. The article also highlights Render's support for Infrastructure-as-Code through Blueprints, enabling users to orchestrate multiple services without manual intervention, and provides additional tips for a successful deployment, such as maintaining environment variable consistency for seamless migration.
