Abiquo 5.4 includes a property and process to enable you to onboard accounts in non-default AWS regions, which are disabled by default, such as Bahrain.
To onboard an account in a non-default region, follow the steps described at Onboard an account in a nondefault AWS region.
This will ensure that users can work in the region and all hardware profiles and availability zones are onboarded for use in the multi-cloud platform.
