title: google ai platform vs ml engine
body: <p>I did lots of search, but I cannot understand what the difference between <code>google ai platform</code> and <code>ml engine</code>.</p>
  
  <p>It seems that both of them can be used for training and deploying models.</p>
  
  <p>Other words like google-cloud-automl, google ai hub are also very confusing.</p>
  
  <p>What are the differences between them? Thanks</p>
