Description: The EC2 Network Load Balancer is a service that operates at the connection level (Layer 4) and is responsible for distributing network traffic to multiple destinations based on IP protocol data. This load balancer manages incoming traffic to Amazon EC2 instances, ensuring that requests are efficiently distributed among available resources. By operating at the transport layer, the load balancer can handle both TCP and UDP traffic, making it a versatile option for applications requiring high performance and low latency. Key features include the ability to automatically scale based on traffic, integration with other cloud infrastructure tools, and the capability to monitor and log connections. Its relevance lies in improving the availability and resilience of applications, allowing users to experience a smoother and more reliable service. Additionally, the EC2 Network Load Balancer is essential for microservices architectures and distributed applications, where efficient traffic management is crucial for overall system performance.
