Building a Scalable AWS Application Architecture: From EC2 to Load Balancer and Auto Scaling

A scalable AWS application architecture is designed to handle increased user traffic, maintain availability, and recover from failures automatically. This is achieved by using Amazon EC2 instances, Load Balancers, and Auto Scaling. Terraform can automate the creation of infrastructure, including VPCs, EC2 instances, Load Balancers, and Security Groups. To implement this architecture, follow steps 2-5: launch EC2 instances using Terraform, add an Application Load Balancer, implement Auto Scaling, and secure the architecture with Security Groups. This design ensures high availability and scalability for production-ready applications.
