title: Migrate s3 data to google cloud storage
body: <p>I have a python web application deployed on Google App Engine.</p>
  
  <p>I need to grab a log file stored on Amazon S3 and load it into Google Cloud Storage. Once it is in Google Cloud Storage I may need to perform some transformations and eventually import the data into BigQuery for analysis.</p>
  
  <p>I tried using gsutil as a some sort of proof of concept, since boto is under the hood of gsutil and I'd like to use boto in my project. This did not work.</p>
  
  <p>I'd like to know if anyone has managed to transfer file directly between the 2 clouds. If possible I'd like to see a simple example. In the end this task has to be accomplished through code executing on GAE. </p>
