title: AWS Personalize in Cost Explorer
body: <p>I am using for 4 dataset group for example:-</p>
  
  <ol>
  <li>Movies</li>
  <li>Mobile</li>
  <li>Laptops</li>
  <li>AC</li>
  </ol>
  
  <p>And in each datasetGroup, we have 3 datasets with name Users, Item and Item_User_INTERACTIONS</p>
  
  <p>And we also have one solution and Campaigns for each dataset group.</p>
  
  <p>I am also sending the real-time event to AWS Personalize using API (putEvent)</p>
  
  <p>The above things cost me about 100USD in two days and showing 498 TPS hours used and I am unable to find the real reason for this much cost.</p>
  
  <p>Or does AWS Personalize simply cost this much?</p>
