A company is hosting an election reporting website on AWS for users around the world. The website uses Amazon EC2 instances for the web and application tiers in an Auto Scaling group with Application Load Balancers. The database tier uses an Amazon RDS for MySQL database. The website is updated with election results once an hour and has historically observed hundreds of users accessing the reports.
The company is expecting a significant increase in demand because of upcoming elections in different countries. A solutions architect must improve the website’s ability to handle additional demand while minimizing the need for additional EC2 instances.
Which solution will meet these requirements?
A. Launch an Amazon ElastiCache cluster to cache common database queries.
B. Launch an Amazon CloudFront web distribution to cache commonly requested website content.
C. Enable disk-based caching on the EC2 instances to cache commonly requested website content.
D. Deploy a reverse proxy into the design using an EC2 instance with caching enabled for commonly requested website content.
