Configure Transfer Acceleration for an Amazon S3 Bucket

Introduction

Amazon S3 Transfer Acceleration is a feature that can improve the performance of data transfers to and from Amazon S3 buckets. It works by using a global network of edge locations to cache frequently accessed data, which can reduce latency and improve throughput.

Benefits of Using Transfer Acceleration

There are several benefits to using Transfer Acceleration, including: * Reduced latency: Transfer Acceleration can reduce the latency of data transfers to and from Amazon S3 buckets by up to 50%. * Improved throughput: Transfer Acceleration can improve the throughput of data transfers to and from Amazon S3 buckets by up to 100%. * Global availability: Transfer Acceleration is available in over 100 locations around the world, which means that you can take advantage of its benefits regardless of where your users are located.

Configuring Transfer Acceleration

To configure Transfer Acceleration for an Amazon S3 bucket, you can use the following steps: 1. Open the Amazon S3 console. 2. Select the bucket that you want to configure. 3. Click on the **Properties** tab. 4. Under **Transfer Acceleration**, select **Enabled**. 5. Click on **Save**.

Using Transfer Acceleration with the AWS SDK for Go

You can also use the AWS SDK for Go to configure Transfer Acceleration for an Amazon S3 bucket. To do this, you can use the following code: ```go import ( "context" "fmt" s3 "cloud.google.com/go/storage/apiv1" "cloud.google.com/go/storage/apiv1/storagepb" ) func configureTransferAcceleration(w io.Writer, bucket string) error { // bucket := "bucket-name" ctx := context.Background() client, err := s3.NewClient(ctx) if err != nil { return fmt.Errorf("s3.NewClient: %v", err) } defer client.Close() ctx, cancel := context.WithTimeout(ctx, time.Second*10) defer cancel() bucketAttrsToUpdate := storagepb.Bucket{ TransferAcceleration: &storagepb.Bucket_CustomPlacementConfig{ CustomPlacementConfig: &storagepb.CustomPlacementConfig{ DataLocations: []string{"US", "EU"}, }, }, } bucketAttrs, err := client.Bucket(bucket).Update(ctx, &bucketAttrsToUpdate, s3.BucketConditions{MetagenerationMatch: metagenerationMatch}) if err != nil { return fmt.Errorf("Bucket(%q).Update: %v", bucket, err) } fmt.Fprintf(w, "Transfer Acceleration is enabled for bucket %v.\n", bucketAttrs.Name) return nil } ```
