    A company has a global news website hosted in a fleet of EC2 Instances. Lately, the load on the website has increased which resulted in slower response time for the site visitors. This issue impacts the revenue of the company as some readers tend to leave the site if it does not load after 10 seconds.

    Which of the below services in AWS can be used to solve this problem?

    Correct answers are:

  • Use Amazon CloudFront with website as the custom origin.

  • Use Amazon ElastiCache for the website’s in-memory data store or cache.

    How do we know that the content isn’t dynamic on every load and therefore cannot be cached rendering Cloudfront not applicable? How do we know that the system would improve with Redis or Memcache ? Obviously there are the only two reasonable answers but they require us to make some assumptions don’t they?
