Enterprise CRM Platform: Multi-AZ ECS Fargate Deployment with Zero EC2 Management
Built highly available serverless container infrastructure for CRMified using AWS ECS Fargate across 2 AZs with modular CloudFormation stacks and zero EC2 management overhead.
Key Results
Multi-AZ high availability
Fully serverless with Fargate
All infrastructure in CloudFormation
Cross-stack exports for flexibility
What We Were Solving
CRMified, an enterprise CRM platform, was experiencing growing pains as they scaled to serve larger enterprise customers. Their single-server deployment model couldn't meet the availability requirements of Fortune 500 clients evaluating their platform.
Key challenges included:
- Single point of failure — any infrastructure issue meant complete platform downtime for all customers
- Manual EC2 management consuming significant DevOps time for patching, scaling, and maintenance
- Enterprise clients requiring 99.9% uptime SLAs that current architecture couldn't guarantee
- No reproducible infrastructure — manual AWS console changes leading to configuration drift between environments
- SOC 2 compliance audit approaching, requiring documented infrastructure controls and change management
How We Solved It
We designed and implemented a production-grade AWS infrastructure that eliminated single points of failure while significantly reducing operational overhead.
Multi-AZ Architecture
Built a highly available VPC spanning two availability zones with automatic failover. Application containers run simultaneously in both AZs, ensuring that a complete data center failure doesn't impact customer access.
Serverless Container Platform
- Migrated from EC2 to ECS Fargate — eliminating all server management, patching, and capacity planning
- Configured awsvpc networking mode for enhanced security with container-level network isolation
- Implemented Application Load Balancer with health checks and automatic unhealthy target removal
Infrastructure as Code
- Created modular CloudFormation templates with cross-stack exports for clean separation of concerns
- Version-controlled infrastructure enabling audit trails for SOC 2 compliance requirements
- One-click environment replication for staging, QA, and disaster recovery scenarios
Technologies Used
“The modular CloudFormation design makes infrastructure changes straightforward. We can update the ECS service without touching the VPC, and the multi-AZ setup gives us confidence in availability during zone outages.”
