What will minimize latency by reducing load on the S3 bucket?
Migrate the S3 bucket to a region that is closer to end users’ geographic locations.
Use cross-region replication to replicate all of the data to another region.
Create an Amazon CloudFront distribution with the S3 bucket as the origin.
Use Amazon ElastiCache to cache data being served from Amazon S3.
Explanations:
Migrating the S3 bucket to a closer region may reduce latency for users, but it doesn’t directly address high read operations or load on the bucket itself. It may also cause additional complexity in terms of data transfer and availability.
Cross-region replication increases redundancy and availability across regions but does not help reduce latency or load on the original bucket for high read operations.
Creating a CloudFront distribution with the S3 bucket as the origin helps minimize latency by caching content closer to end users. This reduces the load on the S3 bucket and improves access times for static content.
ElastiCache is designed to cache data from dynamic applications and databases, not static content from S3. It would not help reduce the load on the S3 bucket in this scenario.
I rank that the answer is:
Create an Amazon CloudFront distribution with the S3 bucket as the origin.
