Hyperglance supports IAM.
All you need to do is specify which instances, regions and availability zones you want to bring into Hyperglance using IAM.
For Hyperglance to function correctly you will need to grant your IAM account read-access to the regions and availability zones.
Once the IAM account is created enter the public and private key as an account on the Hyperglance server's 'Settings' page ( https://<ip>/#/admin ).
