Can ELB Be Used Across Accounts or VPCs?¶
Your Shared load balancers cannot be used by another account, and you cannot associate backend servers whose VPCs are not the same as the load balancers.
For Dedicated load balancers, you can add servers in a VPC connected using a VPC peering connection, in a VPC in another region and connected through a cloud connection, or in an on-premises data center at the other end of a Direct Connect or VPN connection, by using their IP addresses. For details, see section Configuring Hybrid Load Balancing in Elastic Load Balance User Guide.
