Introduction to Network Load Balancer NLB
Network Load Balancer NLB (Network Load Balancer) is a new generation of four-layer load balancer specifically designed for TCP/UDP protocols, supporting ultra-high performance and rich features, full port support, and advanced features such as cross-domain mounting.
Product Components
- NLB Load Balancer Instance: It accepts traffic from the client and forwards requests to one or more backend servers.
- Listener: Each listener requires you to configure the protocol and port to listen to requests from the client, as well as set up how the traffic is distributed, etc. Different listeners are used to handle different business traffic, forwarding requests to a backend service node according to your defined forwarding strategy.
- Service Node: The real handling of client traffic backend server, service nodes can be cloud server instances, elastic network cards, or IP addresses.
Product Advantages
