Cloudfront Quiz
You have a web application hosted on an EC2 Instance in AWS which is being accessed by users across the globe. The Operations team has been receiving support requests about extreme slowness from users in some regions. What can be done to the architecture to improve the response time for these users?
A. Add more EC2 Instances to support the load.
B. Change the Instance type to a higher instance type.
C. Add Route 53 health checks to improve the performance.
D. Place the EC2 Instance behind CloudFront.
D. Place the EC2 Instance behind CloudFront.
AWS Documentation mentions the
following:
Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you’re serving with CloudFront, the user is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.

Option A is in. The latency issue is experienced by people from certain parts of the world only. So, increasing the number of EC2 Instances or increasing the instance size does not make much of a difference. Option C is in. Route 53 health checks are meant to see whether the instance status is healthy or not. Since this case deals with responding to requests from users, we do not have to worry about this. However, for improving latency issues, CloudFront is a good solution.
