QUESTION 10 OF 30

What is a lower latency interaction, and why is it desirable in an application?

Latency is the time it takes for a communication to occur within an IT Network. The higher the latency, the slower the applications of the more time the user spends waiting for responses to their queries or input. Therefore, low latency is always more desirable. Not only should you know this, but you should be able to provide the Amazon interviewer with examples of how you reduce latency between applications and across the network.

"Reducing latency across the network is an issue I am constantly addressing. One of the ways I reduced latency this through the use of WebSockets. These establish connections across the network and reduce the number of round-trip packets required to establish a TCP connection. Other methodologies for reducing latency include segmenting the network, greeting groups which frequently communicate with each other, and using high-performance network hardware and applications."
