[[i2Rest_Server|i2Rest Server]] functionality is very similar to IBM Integrated Web Services. Both products allow you to turn RPGLE programs into services without modifications. However, the i2Rest Server is an independent product that differs significantly from the IBM IWS<br/>
In short, there are two main differences:
* Full support of OAuth2 authorization flows
* Higher performance
