How We Migrated from Heroku to Amazon Web Services (AWS) Using Docker

Description and use

The team migrated their application from Heroku to AWS using Docker, Elastic Beanstalk, RDS, and ElastiCache, reducing costs and increasing infrastructure control.

Problem

The team needed to move their application from Heroku to AWS to gain more control over infrastructure and reduce costs.

Outcome

The migration completed with minimal downtime, improved scalability, and lower operational overhead.

Workflow

• 1. Containerized the application with Docker.
• 2. Created a Dockerfile and docker-compose.yml for local development.
• 3. Pushed the image to Amazon ECR.
• 4. Configured Elastic Beanstalk to use the Docker image.
• 5. Migrated the PostgreSQL database to Amazon RDS.
• 6. Migrated Redis to ElastiCache.
• 7. Updated environment variables and secrets.
• 8. Tested the application in the new environment.
• 9. Decommissioned the Heroku deployment.
