Question 1 of 30
A company is experiencing rapid growth in its online services, leading to fluctuating demand for its web application. The application is hosted on AWS and currently uses an EC2 instance with a fixed size. The company wants to ensure that the application can handle sudden spikes in traffic without performance degradation while also optimizing costs during low-traffic periods. Which approach should the company take to achieve both scalability and elasticity in its cloud infrastructure?
Implement Auto Scaling to automatically adjust the number of EC2 instances based on traffic demand.
Increase the size of the existing EC2 instance to a larger instance type to handle more traffic.
Use a load balancer to distribute traffic across multiple fixed-size EC2 instances.
Migrate the application to a single larger EC2 instance with a reserved instance pricing model.
