Today, we are announcing the public preview of Azure cross-subscription Load Balancer. Cross-subscription load balancing enables the load balancers components to be located in different subscriptions. For example, the frontend IP address or the backend instances could be located in a different subscription from the one that the load balancer belongs to.
Cross-subscription load balancing is available in all Azure public regions, China cloud regions, and Government cloud regions.
Learn more about cross-subscription load balancer via our public documentation or our recent blog.
