Question
A company that is in the ap-northeast-1 Region has a fleet of thousands of AWS Outposts servers. The company has deployed the servers at remote locations around the world. All the servers regularly download new software versions that consist of 100 files. There is significant latency before all servers run the new software versions.
The company must reduce the deployment latency for new software versions.
Which solution will meet this requirement with the LEAST operational overhead?
A. Create an Amazon S3 bucket in ap-northeast-1. Set up an Amazon CloudFront distribution in ap-northeast-1 that includes a CachingDisabled cache policy. Configure the S3 bucket as the origin. Download the software by using signed URLs.
B. Create an Amazon S3 bucket in ap-northeast-1. Create a second S3 bucket in the us-east-1 Region. Configure replication between the buckets. Set up an Amazon CloudFront distribution that uses ap-northeast-1 as the primary origin and us-east-1 as the secondary origin. Download the software by using signed URLs.
C. Create an Amazon S3 bucket in ap-northeast-1. Configure Amazon S3 Transfer Acceleration. Download the software by using the S3 Transfer Acceleration endpoint.
D. Create an Amazon S3 bucket in ap-northeast-1. Set up an Amazon CloudFront distribution. Configure the S3 bucket as the origin. Download the software by using signed URLs.
Answer
The best solution to reduce deployment latency for new software versions on the company’s global fleet of AWS Outposts servers with the least operational overhead is:
D. Create an Amazon S3 bucket in ap-northeast-1. Set up an Amazon CloudFront distribution. Configure the S3 bucket as the origin. Download the software by using signed URLs.
Explanation
- Creating an Amazon S3 bucket in the ap-northeast-1 Region allows the company to store the software files in a centralized location. S3 provides high durability, scalability, and performance for storing and retrieving objects.
- Setting up an Amazon CloudFront distribution with the S3 bucket as the origin enables the company to distribute the software files globally through the CloudFront edge locations. CloudFront is a content delivery network (CDN) that caches content at edge locations worldwide, reducing latency and improving download speeds for users in different regions.
- By using signed URLs, the company can securely grant time-limited access to the software files stored in the S3 bucket. Signed URLs ensure that only authorized AWS Outposts servers can download the software, preventing unauthorized access.
- This solution does not require additional configuration or management of multiple S3 buckets or complex replication setups, minimizing operational overhead.
The other options have drawbacks:
A. Setting a CachingDisabled cache policy in the CloudFront distribution would disable caching at the edge locations, negating the benefits of using CloudFront for reducing latency.
B. Creating a second S3 bucket in the us-east-1 Region and configuring replication between the buckets adds unnecessary complexity and operational overhead. It also relies on a specific secondary region rather than leveraging CloudFront’s global edge locations.
C. Using Amazon S3 Transfer Acceleration can improve upload and download speeds for S3 buckets, but it does not provide the same global content distribution capabilities as CloudFront. It may not be as effective in reducing latency for a worldwide fleet of servers.
Therefore, option D offers the most efficient and low-overhead solution to minimize deployment latency for new software versions on the company’s global fleet of AWS Outposts servers.
