The client hosted multiple applications on Heroku but faced increasing limitations in scalability, deployment control, and cost efficiency. HAZERCLOUD migrated the entire application stack to AWS ECS, establishing a scalable and automated containerized infrastructure.
The client hosted multiple applications on Heroku but faced increasing limitations in scalability, deployment control, and cost efficiency. The platform that once enabled rapid delivery was now holding the team back.
HAZERCLOUD migrated the client's application stack from Heroku to AWS ECS, establishing a scalable and automated containerized infrastructure with full CI/CD automation.
A dedicated ECS cluster was provisioned in AWS US East (N. Virginia) to host all nine applications, providing the foundation for a containerized, scalable infrastructure.
Dockerfiles were reviewed and corrected to resolve build errors, missing dependencies, and environment inconsistencies across all applications.
AWS CodePipeline and CodeBuild were configured for automated builds, tests, ECR storage, and ECS deployments — enabling reliable, repeatable releases.
ECS task definitions and services were configured to manage container lifecycle, environment variables, and scaling policies for each application.
Application Load Balancers with port-based listeners routed traffic efficiently to ECS tasks across all applications.
Amazon CloudWatch was configured for centralized logging, performance monitoring, and alerting across the entire platform.
The target architecture running all nine applications on AWS ECS with CodePipeline CI/CD, ALB traffic routing, ECR container storage, CloudWatch observability, and IAM-controlled access.
The migration to AWS ECS enhanced deployment speed, scalability, and operational efficiency across the board.
All nine applications, including the customer personality endpoint and web resume upload, were successfully migrated to ECS without disruption.
CI/CD pipelines with CodePipeline and CodeBuild reduced errors and enabled quicker, more reliable deployments across all applications.
ECS with ALBs allowed services to scale with demand, resolving prior performance issues that plagued the Heroku deployment.
AWS-managed infrastructure freed the team to focus on development rather than managing platform dependencies and environment consistency.
Pay-as-you-go pricing with auto-scaling improved cost efficiency significantly over Heroku's fixed pricing plans.
IAM controls, network isolation, and compliance features strengthened security posture and access control across the platform.
