Question

A live-events company is designing a scaling solution for its ticket application on AWS. The application has high peaks of utilization during sale events. Each sale event is a one-time event that is scheduled. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The application uses PostgreSQL for the database layer. The company needs a scaling solution to maximize availability during the sale events. Which solution will meet these requirements?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Use a scheduled scaling policy for the EC2 instances. Host the database on an Amazon Aurora PostgreSQL Multi-AZ DB cluster. Create an Amazon EventBridge rule that invokes an AWS Lambda function to create a larger Auro... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon Aurora is a high-performance managed relational database with built-in replication and failover.
