根据AEM Cloud服务的架构，它基于AWS云基础架构，因此可以使用AWS提供的服务S3来存储日志文件。具体而言，可以使用Sling Log Tracer OSGi Console来设置路径和文件名，以将日志记录到S3中。

代码示例：

1. 在AEM Console中打开“Configurations”并搜索“Log Tracer”
2. 打开“com.day.cq.commons.servlets.RootMappingServlet”并将其添加到过滤器列表中
3. 设置日志文件的路径和文件名
4. 将日志记录到S3中，使用AWS SDK可以轻松实现。

下面是一个使用AWS SDK的代码示例，将日志文件保存到S3存储桶中：

import com.amazonaws.AmazonClientException;
import com.amazonaws.AmazonServiceException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3Client;
import com.amazonaws.services.s3.model.ObjectMetadata;
import com.amazonaws.services.s3.model.PutObjectRequest;
import com.amazonaws.services.s3.transfer.TransferManager;
import com.amazonaws.services.s3.transfer.TransferManagerBuilder;

public class AEMLogToS3 {

    public static void main(String[] args) {

        String logFilePath = "/logs/cq-auth.2020-01-01.log";
        String bucketName = "my-bucket";
        String s3key = "logs/cq-auth.2020-01-01.log";
        String accessKey = "";
        String secretKey = "";

        AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
        AmazonS3 s3Client = new AmazonS3Client(credentials);

        try {
            TransferManager tm = TransferManagerBuilder.standard()
                    .withS3Client(s3Client)
                    .build();

            PutObjectRequest request = new PutObjectRequest(bucketName, s3key, new File(logFilePath));
            ObjectMetadata metadata = new ObjectMetadata();
            metadata.setContentType("plain/text");
            metadata.addUserMetadata("x-amz-meta-title", "AEM Log File");
            request.setMetadata(metadata);

            tm.upload(request).waitForCompletion();
            System.out.println("Log file uploaded to S3 successfully.");

        } catch (AmazonServiceException ase) {
            System.out.println("AmazonServiceException: " + ase.getMessage());
        } catch (AmazonClientException ace) {
            System.out.println("AmazonClientException: " + ace.getMessage());
        } catch (InterruptedException ie) {
            System.out.println("InterruptedException: " + ie.getMessage());
        }
    }
}
