Today, AWS announces the launch of QUIC protocol support for Network Load Balancer (NLB). This capability enables customers to forward QUIC traffic to their targets with ultra-low latency while maintaining session stickiness using QUIC Connection IDs. In this blog we will provide an overview of QUIC, demonstrate how to enable it using the AWS Console and CLI, and provide additional considerations.
What is QUIC and Why Does It Matter?
QUIC (RFC 9000) represents a fundamental shift in how we approach network communication in our mobile-first world. QUIC is a transport protocol that runs over UDP and provides built-in encryption, congestion control, and multiplexing capabilities. QUIC is the transport protocol for HTTP/3, enabling applications to use HTTP/3 for their workloads to achieve better latency, connection resilience, and reduced head-of-line blocking. Unlike traditional networking protocols designed for static nodes, QUIC is built from the ground up…
