title: Choosing between Google Cloud Flexible or Standard Environment
body: <p>I'm starting to build a web/mobile app that is going to be offered as SaaS.
  I have seen many cloud options for hosting (Heroku, AWS) but finally decided to go with Google Cloud App Engine.</p>
  
  <p>My back-end will be Java based, and I'm confused about going with the Standard or Flexible Env.
  I have read several docs online but still undecided.</p>
  
  <p><em>Considerations to tackle:</em></p>
  
  <ol>
  <li>I am not very experienced with Docker and this is my first Saas App.</li>
  <li><p>My app should run perfectly with the offering of the Standard Env.</p></li>
  <li><p>Migrating from the Standard to the Flex environment seems to bring
  some headache.</p></li>
  </ol>
  
  <p>Would you please help me decide on the way to?</p>
