Understanding Network Latency in Cloud Environments
Network latency represents the time delay between sending a request and receiving a response in cloud applications. As businesses increasingly migrate to cloud infrastructure, understanding and optimizing latency becomes crucial for maintaining competitive advantage and user satisfaction. Network latency optimization directly impacts user experience, conversion rates, and overall application performance.
