Typically, Azure Enterprise Agreement (EA) subscriptions were created in the EA Portal and management of services was completed in the Azure portal. Our goal is to converge on the Azure portal as the primary avenue for users to manage their Azure services and subscriptions.
We are making available the public preview of the create subscription experience in the Azure portal. This capability will directly align with the the ability to create multiple enterprise subscriptions using the Create Subscription API. This experience is fully integrated in the Azure portal and will enable you to quickly get an EA subscription created without any programming.
Read about it in the Azure blog.
