Scalable AWS Architecture Blueprint: Deploying Microservices with ECS Fargate, RDS PostgreSQL, and CloudFront
Architecture reference for deploying enterprise multi-service web applications on AWS: VPC network segmentation, containerized backend services on ECS Fargate, RDS PostgreSQL multi-AZ clusters with connection pooling, and global CDN delivery.
Enterprise Cloud Architecture on AWS
Designing a secure, fault-tolerant cloud platform requires separating compute, persistent storage, and public ingress layers across isolated VPC subnets with strict Security Group boundaries.
1. Serverless Container Workloads on ECS Fargate
By adopting AWS ECS Fargate, we eliminate EC2 server patching while gaining auto-scaling based on CPU utilization and request queue depth. Application Load Balancer (ALB) handles TLS termination and path-based routing.
2. Database Resiliency & Edge Asset Caching
Amazon RDS Aurora PostgreSQL configured with Multi-AZ failover and read replicas pairs with PgBouncer connection pooling to handle high-concurrency spikes. Static media and dynamic uploads are stored in S3 and accelerated worldwide via Amazon CloudFront.
