Secure Multi-Zone ECS Deployment for Modern Insurance Operations

Background

Implemented a highly secure, containerized insurance platform using Amazon ECS with multi-zone replication, automated scaling, and encrypted data handling for real-time insurance operations.

The Challenge

The architecture was designed to address critical challenges around security, scalability, and system integration for containerized applications.
  • Secure & Isolated Containers: Implemented ECS with private subnet isolation, encrypted data handling, and integration with KMS and existing security frameworks.
  • High Availability & Scalability: Enabled multi-zone replication, CPU-based auto-scaling, and regional failover to support dynamic workloads and resilience.
  • Robust Service Communication: Deployed advanced service discovery using private DNS namespaces to manage complex internal service interactions efficiently.

Our Solution

Rambunct implemented a secure, scalable, and highly available ECS-based architecture leveraging multiple AWS services to ensure performance, data integrity, and enterprise-grade security.
  • Secure, Resilient Infrastructure: Deployed ECS services in private subnets with WAF, KMS encryption, certificate verification, secret management, and multi-AZ failover for security and high availability.
  • Modular ECS Architecture: Used ECS Service Groups for frontend, backend, API gateway, and Redis cache; with service discovery, private DNS, CPU-based auto-scaling, and integrated load balancing.
  • Efficient Data & Lifecycle Management: Managed structured and unstructured data via RDS and S3; implemented encrypted transmission, caching with Redis, and active lifecycle flows from frontend to storage.

The Result

The solution delivered high performance, operational efficiency, and robust security through a well-architected AWS containerized setup.
  • High Availability & Speed: Achieved 99.99% uptime and sub-100ms service discovery for responsive and reliable service delivery.
  • Scalable Infrastructure: Enabled successful auto-scaling events to handle dynamic workloads without service disruption.
  • Operational Efficiency: Reduced deployment time, improved resource utilization, and simplified system management.
  • Strengthened Security: Maintained a zero-breach record while enhancing the overall security posture through encryption and isolation.
