title: What's the difference between AWS SSO and AWS Cognito?
body: <p>Let's say I have a few clients: corporation x, y, z. each of those corporation has their employees and their SSO (mostly SAML but can be also OpenId or anything else). </p>
  
  <p>I want to be able to integrate with their SSO so they can log in to my application without giving me their credentials. Something like cloudfoundry UAA. Which one should i use: AWS SSO or AWS Cognito? What's the difference?</p>
