Implementing Serverless Architecture with Amazon ECS
Discover how we replatformed a healthcare application onto Amazon ECS with Fargate to enhance software’s scalability and operational agility.
OUR CUSTOMER
Health Service and Medication Management Marketplace
Healthera is a UK-based digital healthcare platform that allows patients to manage prescriptions, medications, and health services through a single online portal. For pharmacies and healthcare providers, it offers a way to modernize service delivery, reduce administrative workload, and support sustainable business growth in an increasingly digital landscape.
THE CHALLENGE
Legacy Infrastructure Slowing Operations and Delivery
Our customer as a digital health company operating a suite of healthcare applications, faced growing limitations with its IT infrastructure setup. Their environment relied heavily on manually configured EC2 instances spread across multiple development and production environments.
This legacy infrastructure configuration of client’s platform created several challenges:
- Operational Overhead
Infrastructure updates, patching, and environment support consumed significant time and resources due to the lack of automation. - Scaling Bottlenecks
Without a standardized deployment process, scaling workloads or onboarding new services introduced risk and complexity. - Limited Deployment Agility
Without environment isolation and CI/CD pipelines, the platform struggled to release new features quickly or test changes safely.
To support growth and long-term scalability, Healthera needed a cloud-native solution built around infrastructure automation, environment isolation, and deployment efficiency.
THE SOLUTION
Migration to Containerized Architecture on ECS Backed by IaC
After conducting a comprehensive assessment of the existing AWS environment and application architecture, our specialists identified that the infrastructure wasn’t following AWS best practices and recommended a containerization strategy using Amazon Elastic Container Service (ECS) with Fargate.
Key components of implemented solution included:
- Containerization with Docker
We replaced legacy EC2-based workloads with Docker containers to make deployments portable and consistent across environments. - Amazon ECS with Fargate
Leveraging ECS with Fargate allowed engineers to run containers without managing servers, simplifying operations while supporting auto-scaling. - Multi-Account Environment Isolation
By isolating production, staging, and development into separate accounts, we improved access control, deployment safety, and compliance readiness. - Infrastructure as Code with Terraform and Terragrunt
Every resource (from networks to compute and IAM policies) was defined as code. This ensured repeatable, version-controlled deployments and eliminated configuration drift. - CI/CD Pipeline Automation
In the final step, we integrated automated deployment pipelines to accelerate releases and reduce deployment-related errors. - Observability and Monitoring
Integrating CloudWatch metrics with Grafana dashboards and proactive alerts to enhance visibility and accelerate recovery.
