As the accepted answer states, you can't. The best solution I'm aware of is to use:

AWS Kinesis Firehose

https://aws.amazon.com/kinesis/firehose/

Their code sample looks complicated but yours can be really simple. You keep performing PUT (or BATCH PUT) operations onto a Kinesis Firehose delivery stream in your application (using the AWS SDK), and you configure the Kinesis Firehose delivery stream to send your streamed data to an AWS S3 bucket of your choice (in the AWS Kinesis Firehose console).

It's still not as convenient as >> from the Linux command line, because once you've created a file on S3 you again have to deal with downloading, appending, and uploading the new file but you only have to do it once per batch of lines rather than for every line of data so you don't need to worry about huge charges because of the volume of append operations. Maybe it can be done but I can't see how to do it from the console.
