How we moved from Heroku to AWS using Docker

Description and use

Migrating from Heroku to AWS using Docker reduced costs and increased infrastructure control.

Problem

Our application was hosted on Heroku, but we needed more control over infrastructure, cost predictability, and scalability.

Outcome

The migration completed in a few weeks, reducing monthly hosting costs by 30% and providing better scalability and control.

Workflow

• 1. Containerized the application with Docker, creating a Dockerfile.
• 2. Built the Docker image and pushed it to Amazon ECR.
• 3. Created an Elastic Beanstalk environment configured for Docker.
• 4. Deployed the Docker image to Elastic Beanstalk via the EB CLI.
• 5. Migrated the PostgreSQL database from Heroku Postgres to Amazon RDS.
• 6. Updated DNS to point to the new Elastic Beanstalk URL.
• 7. Monitored performance and adjusted instance types as needed.

Evidence

We decided to move to AWS because we wanted more control over our infrastructure and to reduce costs.
