Case Study

How Factual Minds Helped TargetBay Achieve Scalable Microservices on Amazon ECS (EC2)

Challenges

  • Monolithic Single Node TargetBay’s NGINX + PHP-FPM-based APIs ran entirely on a single c5.2xlarge EC2 instance, along with background and batch jobs.
  • Resource Contention Spikes in traffic frequently triggered OOM (Out of Memory) events, causing service crashes and frontend downtime.
  • Limited Scalability & Fault Tolerance Vertical scaling led to service downtime.
  • No redundancy—if the instance failed, all services went offline.
  • Slow Deployment Cycle Releasing updates posed a risk to live traffic, with no safe deployment strategy in place.

Solution Provided by Factual Minds

Factual Minds designed and implemented a modern, containerized architecture using Amazon ECS on EC2, introducing fault isolation, auto-scaling, and path-based routing for service-level flexibility.
Microservices Decomposition
  • Converted each component (e.g., public-api, jobs-processor, admin-api) into Dockerized microservices.
  • Each service managed independently within ECS, enabling fine-grained scaling and deployments.
ECS on EC2 with Auto Scaling
  • Created an ECS Cluster backed by an Auto Scaling Group of EC2 instances (e.g., c5.large).
  • Enabled Spot + On-Demand instance mix to optimize compute spend.
  • Attached an ECS Capacity Provider to dynamically scale container hosts as demand increased.
Load Balancing & Routing

Implemented an Application Load Balancer (ALB):

  • /api/v1/* → public-api
  • /jobs/* → jobs-processor
  • Configured health checks for zero-downtime deployments.
API Gateway Integration
Added Amazon API Gateway (HTTP API) for:
  • Throttling: 100 RPS with burst control.
  • Authentication: IAM token validation.
  • WAF integration for additional security.
Monitoring & Auto Scaling
  • ECS Service Auto Scaling: Configured per-service policies (scale at >60% CPU).
  • CloudWatch Dashboards: Tracked CPU, memory, request latency, and error rates.
  • Centralized logging enabled faster troubleshooting and alerting.
