Which approach will improve the user experience?
Implement Amazon ElastiCache to cache the content and reduce the load on the database.
Enable an Amazon CloudFront distribution with Elastic Load Balancing as a custom origin.
Use Amazon S3 to store and deliver the content.
Enable Auto Scaling for the EC2 instances so that they can scale automatically.
Explanations:
Amazon ElastiCache is useful for caching frequently accessed data in memory, reducing load on the database. However, it doesn’t directly improve the delivery speed of large objects like those generated dynamically and updated daily.
Enabling an Amazon CloudFront distribution with Elastic Load Balancing as a custom origin allows for caching of dynamic content at edge locations closer to users, reducing latency and improving content delivery speed, especially for geographically dispersed users.
Using Amazon S3 to store and deliver the content is a good practice for static content, but it doesn’t address the issue of dynamic content generation and daily updates. S3 is not designed for dynamic content generation based on geographic location.
Enabling Auto Scaling for EC2 instances helps with scaling based on traffic, but it doesn’t address the specific issue of slow content delivery for large objects or dynamic content generation. It improves server availability, not content speed.
I figure that the answer is:
Enable an Amazon CloudFront distribution with Elastic Load Balancing as a custom origin.
