A peek behind the curtain at an infrastructure upgrade Heroku completed last year, migrating to a new-and-improved storage backend for platform metrics.

Heroku offers insights into cloud application development, deployment, and management, providing documentation and best practices for deploying and scaling applications on the Heroku platform. By exploring Heroku's curated content, developers can learn about Heroku's containerized deployment model, continuous delivery workflows, and add-on ecosystem for extending application functionality. Whether you're deploying web applications, APIs, or background workers, Heroku offers resources to streamline your development workflow and focus on building great software.

Heroku migrated to a new and improved storage backend for platform metrics to ensure security, reliability, and performance. The migration involved steps such as setting up parallel stream-processing jobs, running experiments, and gradually transitioning queries to the new storage backend. The migration to AWS's DynamoDB was successful and resulted in a more scalable and efficient system.
