2.5.10 Scalability & Future Enhancements

1. Auto Scaling

• ECS can scale up container tasks based on CPU, memory, or even custom CloudWatch metrics (like number of active WebSocket connections).

• RDS can move to larger instance classes or scale out read replicas.

2. Multi-Region Deployments

• For global coverage and disaster recovery, replicate ECS + RDS across multiple AWS regions (Route 53 latency-based routing).

3. Microservices

• As the platform grows, break monolith into specialized services (Chat Service, Trading Service, etc.).

• Use ECS or EKS to manage multiple containers for each microservice.

4. Global Edge Networking

• For real-time chat, incorporate AWS Global Accelerator or other solutions to reduce latency for users worldwide.
