YugabyteDB 1.1 introduces a new feature that simplifies multi-cloud, hybrid cloud, and multi-region database deployments by providing public IPs to enable easy communication between servers across different regions and clouds. This feature allows users to specify private IP addresses for internal server-to-server communication within a region or cloud, while using public IP addresses for inter-regional or cross-cloud communication. The new flags `rpc_bind_addresses` and `server_broadcast_addresses` are used to configure this functionality, which also includes optional settings such as the `use_private_ip` policy to determine when to use private IP addresses. This feature is designed to address common challenges in multi-cloud and hybrid cloud deployments, where cost is a significant factor in choosing between public and private IP addresses for communication. The new feature provides a more efficient way to deploy and manage databases across different regions and clouds, making it easier to achieve scalability, flexibility, and cost-effectiveness.
