EFA is a network interface for Amazon EC2 instances that enables customers to run applications requiring high levels of inter-node communications at scale on AWS, such as High Performance Computing and Machine Learning. Its custom-built operating system (OS) bypass hardware interface is designed to enhance the performance of inter-instance communications, which is critical to scaling these applications.
