There are times when either a load balancer is not included, such as with VMs, or when you want to provide additional functionality not provided by the standard load balancers – such as the ability to balance between regions. In these cases, we have the option to build and configure our load balancers. You can choose several options, each providing its capabilities depending on your requirements.
