Today, we are launching support for the UDP protocol on Amazon PrivateLink over IPv4 and IPv6, and on Network Load Balancer (NLB) over IPv6. Until now, Amazon PrivateLink only supported TCP, while NLB supported UDP only over IPv4.
Amazon PrivateLink is a highly available and scalable technology that enables you to privately connect your VPC to supported Amazon Web Services services, services hosted by other Amazon Web Services accounts (VPC Endpoint Services) and third-party SaaS services on the Amazon Web Services Marketplace. Network Load Balancer is a high-performance layer 4 load balancer that provides availability and scalability to applications while serving as the single point of contact for clients. This launch enables customers who use Amazon PrivateLink and clients that use IPv6 to access applications such as media-streaming, gaming, VoIP and other applications, that use the UDP protocol.
To use this capability as a service-owner, you can now create a UDP listener on your existing or newly created dual-stack NLBs. A dual-stack NLB supports both IPv4 and IPv6, and can process client requests that use either IP version. You can also attach the NLB to a VPC Endpoint Service, enabling clients to connect over Amazon PrivateLink. Customers that access services over Amazon PrivateLink can now create VPC endpoint of type ‘interface’ to access UDP-based Endpoint Services, just like they access TCP-based services today.
There are no additional charges for this capability. Standard charges for Amazon PrivateLink and Network Load Balancer apply. The capability is available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
