The use of BYOIP in AWS Global Accelerator allows for the sharing of IP addresses between accounts, reducing the need to provision multiple IP ranges for different accounts. This can help avoid underutilized IP address ranges. BYOIP enables the sharing of IP address ranges among multiple AWS accounts, providing static IP addresses for routing traffic to application workloads across the global AWS network infrastructure. This feature allows for greater control over shared IP addresses and can help manage costs associated with public IPv4 addresses.
Cross-account configuration for BYOIP allows for more efficient management of multiple IP address ranges when using your own IP addresses with accelerators deployed in various accounts. This setup offers flexibility in creating multi-account architectures and reduces the complexity of managing numerous IP ranges.
To configure BYOIP sharing between accounts, users can create an attachment specifying the shared resources and authorized principals. This attachment allows specified accounts to use shared BYOIP addresses as static IPs for accelerators within the account.
Overall, BYOIP between accounts in AWS Global Accelerator is a powerful feature that enables efficient management of IP addresses and provides flexibility for creating scalable multi-account architectures. This feature can improve control over shared IP addresses, reduce costs, and streamline the management of IP address ranges across multiple accounts.
