title: Stackdriver vs ELK for app engine
body: <p>Im a little confused about this because the <a href="https://cloud.google.com/appengine/articles/logging" rel="noreferrer">docs</a> say I can use stackdriver for "Request logs and application logs for App Engine applications" so does that mean like web requests? Does that mean like millions of web requests?</p>
  
  <p>Stackdriver's pricing is per resource so does that mean I can log all of my web servers web request logs (which would be HUGE) for no extra cost (meaning I would not be charged by the volume of storage the logs use)?</p>
  
  <p>Does stackdriver use GCP cloud storage as a backend and do I have to pay for the storage? It just looks like I can get hundreds of gigabytes of log aggregation for virtually no money just want to make sure Im understanding this.</p>
  
  <p>I bring up ELK because elastic just partnered with google so it must not do everything elasticsearch does (for almost no money) otherwise it would be a competitor?</p>
