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

说明与用途

团队使用 Docker 将应用从 Heroku 迁移到 AWS，以降低成本并获得更大的基础设施控制权。

问题

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

结果

The migration completed with the application running on AWS ECS Fargate, providing comparable scalability to Heroku while reducing monthly costs and increasing control over the runtime environment.

工作流

• 1. Containerized the application using Docker.
• 2. Created a Dockerfile and built the image locally.
• 3. Pushed the image to Amazon Elastic Container Registry (ECR).
• 4. Defined ECS task definitions and services.
• 5. Configured networking, load balancing, and auto‑scaling on AWS.
• 6. Migrated database and environment variables to AWS RDS and Parameter Store.
• 7. Tested the deployment and switched traffic from Heroku to AWS.

证据

We migrated from Heroku to AWS using Docker, which allowed us to maintain the same deployment process while gaining more control over the infrastructure.
