What is IBM Cloud® Load Balancer? With IBM Cloud load balancers, you can load balance traffic among your servers to help improve uptime. You can also easily scale your applications by adding or removing servers, with minimal disruption to your traffic flows. IBM Cloud offers both VPC and classic load balancers. For VPC infrastructure, there are two varieties of load balancers: application load balancers for VPC and network load balancers for VPC. For classic infrastructure, IBM Cloud offers several options including IBM Cloud Load Balancer and Citrix NetScaler appliances.

Use cases

About IBM Cloud Network Load Balancer for VPC Use the IBM Cloud Network Load Balancer for VPC (NLB) to distribute traffic among multiple server instances within the same region of your VPC. Network load balancers can accept members across all three availability zones, while the NLB itself resides in one specific zone. Learn more
Deploy isolated workloads across multiple locations and zones This tutorial walks you through the steps for setting up highly available and isolated workloads by provisioning IBM Cloud Virtual Private Clouds (VPCs). You will create virtual server instances (VSIs) in multiple zones within one region to ensure the high availability of the application. You will also create additional VSIs in a second region and configure a global load balancer (GLB) to provide high availability between regions and reduce network latency for users in different geographies.
