Elastic Fabric Adapter Icon

Elastic Fabric Adapter (EFA) is a virtual interface that allows for extremely high-speed, low-latency networking between Amazon EC2 instances. It's perfect for applications that need to move large amounts of data quickly, such as high-performance computing (HPC) workloads, machine learning training jobs, and big data analytics. EFA improves communication speed between compute nodes significantly compared to standard networking, enabling faster processing and reduced completion times for computationally intensive tasks.
