title: How do I lower the cost of AWS on iOS App?
body: <p>I am trying to understand my AWS Cost Report. I am developing a social media app that uses AWS for database and storage. This month's cost was 250$ and I am the only user of the app. Is this normal? My plan was to release the app and get more users onboard but I am very scared of this now.</p>
  
  <p>Services that I am using: </p>
  
  <ul>
  <li>AppSync/DynamoDB. </li>
  <li>S3 </li>
  <li>AWSCloudFront</li>
  <li>Cognito</li>
  </ul>
  
  <p>I have 2 tables on DynamoDB (AppSync).  I converted them to global tables so people in other countries could use the app too. I chose 3 regions : Asia/Tokyo, EU/London and US/California. </p>
  
  <p>I don't understand well the difference on the costs by EC2 and relational database service</p>
  
  <p>Do you have any suggestions to lower the costs? Will be enough if I remove the global tables? </p>
