title: Amazon RDS Instance type connection limits
body: <p>I am trying to decide which AWS RDS instance type is to be used.</p>
  
  <p>I have the stats of the number of database connections required by the application.</p>
  
  <p><strong>Is it possible to know which AWS RDS instance type supports how many database connections approximately?</strong></p>
  
  <p>I have the following list with me, but I'm not sure how accurate it is to date:</p>
  
  <pre><code>t2.micro   66
  t2.small   150
  m3.medium  296
  t2.medium  312
  m3.large   609
  t2.large   648
  m4.large   648
  m3.xlarge  1237
  r3.large   1258
  m4.xlarge  1320
  m2.xlarge  1412
  m3.2xlarge 2492
  r3.xlarge  2540
  </code></pre>
  
  <p>Is there any official AWS document for the same?</p>
