Which solution will meet these requirements with the LEAST operational overhead?
Configure the application to write each object to both S3 buckets. Set up an Amazon Route 53 public hosted zone with a record set by using a weighted routing policy for each S3 bucket. Configure the application to reference the objects by using the Route 53 DNS name.
Create an AWS Lambda function to copy objects from the S3 bucket in us-east-1 to the S3 bucket in the second Region. Invoke the Lambda function each time an object is written to the S3 bucket in us-east-1. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins.
Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins.
Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. If Lawyer is required, update the application code to load S3 objects from the S3 bucket in the second Region.
Explanations:
This option involves manually managing object writes to two separate S3 buckets, which increases operational overhead. The use of a weighted routing policy in Route 53 would also complicate access to static assets and introduce potential inconsistencies between the two buckets.
While using a Lambda function to copy objects to the second S3 bucket would ensure data is replicated, it adds unnecessary complexity and operational overhead. The application would need to invoke the Lambda function each time an object is written, which could lead to potential latency and failure points. CloudFront could help, but the overall solution is still more complex than needed.
Configuring S3 replication allows for automatic and seamless copying of objects from the primary bucket in us-east-1 to the secondary bucket in another region with minimal operational overhead. Utilizing CloudFront to manage access to both buckets as origins provides resilience and improves performance with caching.
Although this option also uses S3 replication, it adds complexity by requiring the application code to be updated to reference the secondary bucket. This introduces additional operational overhead and potential for errors if not all access patterns are correctly updated.
If I’m correct, the answer is:
Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins.
If memory serves me right, the answer is:
Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins.
