Enhancing S3 Bucket Performance with AWS AMS Accelerate

In today's fast-paced digital environment, the performance of your applications can significantly impact user experience and business operations. One common challenge many organizations face is the intermittent slow download speeds from Amazon S3 buckets, which can be particularly problematic for applications that rely on rapid access to large files, such as audio or video content. Fortunately, AWS provides a powerful feature called AMS Accelerate, designed to enhance the performance of S3 buckets and resolve such issues.

Understanding the Problem

In one of our recent projects, we encountered an issue where audio files stored in S3 buckets were taking an unusually long time to download. This intermittent delay was affecting the application's overall performance and user satisfaction. Despite various attempts to optimize the system, the problem persisted, leading us to explore more advanced solutions.

The Common Solution: CloudFront

Amazon CloudFront, AWS's Content Delivery Network (CDN), is the most common way to enhance performance. By caching content at edge locations worldwide, CloudFront reduces latency and improves download speeds for users regardless of their location. However, in scenarios where minimal latency is crucial, such as remote surgery where a surgeon operates from a different location, even faster performance may be necessary.

The Solution: AWS AMS Accelerate

AMS Accelerate is an AWS Managed Service that offers a range of features designed to improve the performance and management of AWS environments. When applied to S3 buckets, AMS Accelerate optimizes data transfer speeds by leveraging AWS's global network of edge locations. This significantly reduces latency and increases throughput, making it an excellent choice for applications where minimal latency is critical.

Implementation and Results

After enabling AMS Accelerate on our S3 buckets, we observed a dramatic improvement in the download speeds of our audio files. The feature helped mitigate the intermittent delays, providing a smoother and faster experience for end-users. The optimization process involved the following steps:

  1. Testing in Development: Like with all changes, it's crucial to test thoroughly in a development environment before deploying to production. We started by enabling AMS Accelerate on our DEV S3 buckets, running various performance tests to ensure stability and reliability.

  2. Updating URLs: AMS Accelerate works on URLs, so it was essential to ensure that all URLs in our staging and production environments were updated to use the accelerate endpoint. This step involved auditing and modifying our application's codebase to point to the new accelerated URLs.

  3. Monitoring Performance: After deploying the changes, we continuously monitored the application's performance metrics to verify the improvements and ensure there were no unforeseen issues.

Best Practices

While AMS Accelerate can significantly enhance the performance of your S3 buckets, it's important to follow best practices to maximize its benefits:

  • Thorough Testing: Always test changes in a controlled development environment before rolling them out to production. This helps identify potential issues and ensures the stability of your application.

  • URL Management: Ensure all relevant URLs are updated to use the accelerate endpoint in both staging and production environments. This step is critical for leveraging the full benefits of AMS Accelerate.

  • Continuous Monitoring: After implementation, continuously monitor the performance of your application to ensure the changes are having the desired effect and to catch any anomalies early.


AWS AMS Accelerate is a powerful tool that can help resolve performance issues with S3 buckets, particularly those related to intermittent slow download speeds. By optimizing data transfer speeds and reducing latency, AMS Accelerate can significantly improve the performance and user experience of applications that rely on S3 storage.

In our case, implementing AMS Accelerate resolved the issue with slow audio file downloads, demonstrating its effectiveness. However, as with any significant change, thorough testing and careful implementation are essential to ensure success.

If you're facing similar performance challenges with your S3 buckets, consider leveraging AWS AMS Accelerate to enhance your application's efficiency and user satisfaction. For scenarios where latency needs to be minimized, such as remote surgery, AMS Accelerate offers a robust solution to ensure optimal performance and reliability.
