title: Cost efficient architecture for a lot of URL Fetch Requests on GAE
body: <p>What would be the most cost efficient architecture on GAE to handle a lot of concurrent URL Fetch Requests? (Python)</p>
  
  <p>I am talking of hundreds of thousands concurrent API Requests.</p>
  
  <p>To do it with task queues and synchronous URL Fetch requests doesn't work, as the latency due to waiting for the response is to high and a lot of instances will be started.</p>
  
  <p>With asynchronous URL fetches I have the problem, that the memory is way to small to handle the responses on one instance, so that it crashes.</p>
  
  <p>How would a general cost efficient architecture for this look like on appengine?
  Really appreciate any advise!</p>
