Solution
How Cloudelligent Accelerated the Therapy EHR Software Company’s Objectives
Cloudelligent designed and implemented a secure, scalable AWS-native architecture, executing a phased migration for our customer from Heroku to AWS.
1
Governance and Multi-Account Foundation
Our team established a secure landing zone using AWS Control Tower to implement multi-account governance and security guardrails from the outset. We deployed a highly available Amazon VPC with segmented networking and cost-optimized NAT gateways. This provided a hardened foundation for the company’s sensitive workloads while ensuring least-privilege access through IAM and GitHub OIDC integrations.
2
Modernized Containerized Compute and Caching
To replace the legacy Heroku environment, Cloudelligent transitioned application services, workers, and integrations to Amazon ECS (Fargate). This serverless approach eliminates infrastructure management overhead while providing seamless scalability. To enhance performance and support messaging queues, we integrated Amazon ElastiCache (Redis), while Amazon CloudFront and Amazon Route 53 were deployed to optimize global frontend delivery and DNS management.
3
Scalable Data Architecture and Secure Storage
We migrated the data layer to Amazon RDS (PostgreSQL), incorporating a Read Replica to isolate reporting traffic and improve primary database performance. For object storage, Amazon S3 was implemented with AWS KMS encryption to ensure data at rest remains secure. This architecture ensures that as our customer grows, their data tier remains resilient, performant, and compliant with modern security standards.
4
Phased Migration and Perimeter Security
Our team executed a “Replicate → Freeze → Flip” strategy, leveraging c for continuous data replication to minimize cutover downtime. Before go-live, the environment was further hardened with AWS Web Application Firewall (WAF) for application-layer protection and Amazon CloudWatch for real-time monitoring and alerting. This phased approach allowed for full validation in staging environments, significantly reducing migration risk and improving overall operational visibility.
Results & Benefits
Scalable, Secure, and Future-Proof AWS Modernization
Cloudelligent’s solution focused on containerization, database replication, and robust governance controls. We utilized a minimal-downtime cutover strategy to ensure total business continuity.
Seamless Modernization and High-Performance AWS-Native Infrastructure
The migration successfully transitioned the company’s core applications to a modernized, containerized architecture with minimal downtime, leveraging continuous replication and structured cutover strategies to ensure total business continuity.
Unprecedented Scalability and Resource Efficiency
By moving to an Amazon ECS (Fargate) auto-scaling architecture, our customer can now dynamically adjust compute resources to match real-time customer demand. This eliminates the constraints of the legacy Heroku environment, ensuring the platform remains performant during peak usage while optimizing costs during lower-traffic periods.
Enhanced Reliability and Minimized Operational Risk
The “Replicate → Freeze → Flip” strategy, supported by AWS Web Application Firewall (WAF), ensured a smooth transition with zero data loss. By isolating heavy reporting traffic to Amazon RDS Read Replicas, the team successfully reduced database contention, leading to more stable application performance and a significant reduction in transaction timeouts.
Fortified Security Posture and Centralized Governance
With the implementation of AWS Control Tower and AWS Web Application Firewall (WAF), the company gained enterprise-grade governance and application-layer protection. Centralized logging via CloudWatch and data encryption through AWS KMS provide deep visibility and rigorous data protection, meeting the high compliance standards required for healthcare-related environments.
Streamlined CI/CD and Faster Innovation Cycles
The integration of GitHub OIDC and Amazon ECR has automated the deployment pipeline, reducing the administrative burden on the engineering team. This shift to a secure, automated CI/CD workflow allows the Therapy EHR Software Company to roll out updates and new features with greater confidence and frequency, accelerating their time-to-market.
