IBM Cloud VPC Network Load Balancer -- Java SDK Examples

 What is Network Load Balancer (NLB)?

Network Load Balancer works in Layer 4 and is best fit for business-critical and interactive workloads that require high throughput and low latency.

With traditional load balancer, all incoming and returning traffics would go through the load balancer itself. The big disadvantage is the high volume of traffics will increase the latency and affect the throughput.

NLB is using a technology called Direct Server Return (DSR). The information processed by the backend targets is sent directly back to the client, thus minimizing latency and optimizing throughput performance.

Java SDK

This Java SDK is a new tool for developer to manage their IBM Cloud VPC resources. If you are new to Java and need to use the Java SDK to manage your NLB on IBM Cloud VPC, this doc can help you to get start.
