Question
A company wants to migrate an application to AWS. The application runs on Docker containers behind an Application Load Balancer (ALB). The application stores data in a PostgreSQL database. The cloud-based solution must use AWS WAF to inspect all application traffic. The application experiences most traffic on weekdays. There is significantly less traffic on weekends. Which solution will meet these requirements in the MOST cost-effective way?
Options
- AUse a Network Load Balancer (NLB). Create a web access control list (web ACL) in AWS WAF
- BCreate a web access control list (web ACL) in AWS WAF that includes the necessary rules.
- CCreate a web access control list (web ACL) in AWS WAF that includes the necessary rules.
- DUse a Network Load Balancer (NLB). Create a web access control list (web ACL) in AWS WAF
Explanation
Using an Application Load Balancer (ALB) allows for integration with AWS WAF to inspect all incoming traffic. Running the application on Amazon ECS provides a scalable and managed container orchestration service. Utilizing Amazon Aurora Serverless for the PostgreSQL database offers automatic scaling based on application demand, which is cost-effective for workloads with variable traffic patterns, such as higher traffic on weekdays and lower traffic on weekends.
