SmartNIC

A SmartNIC is a programmable network interface card that offloads advanced networking, security, and storage tasks from the CPU, improving performance and efficiency in cloud and data center environments.

A SmartNIC (Smart Network Interface Card) is an advanced network adapter that incorporates programmable hardware components, such as FPGAs or dedicated processors. Unlike traditional NICs, SmartNICs can offload complex networking, security, and storage functions from the host CPU, including packet filtering, encryption, load balancing, and virtual switching.

SmartNICs are widely used in cloud and data center environments to enhance performance, reduce CPU overhead, and improve network security. By handling tasks at the network edge, SmartNICs enable more efficient data processing, lower latency, and better scalability for demanding workloads like AI, machine learning, and high-frequency trading.

Leading SmartNIC vendors include NVIDIA (BlueField), Intel, and Broadcom. Their adoption is growing as organizations seek to optimize infrastructure for cloud-native and distributed applications.
