While the AWS Cloud provides many additional components and services beyond what is offered by Application Load Balancer(ALB), Kemp’s Virtual LoadMaster for AWS has additional and enhanced features and capabilities that provide a rich set of integrated functionality, easily configured and managed via the Web User Interface. The same set of capabilities are available when LoadMaster, as an appliance or virtual machine, is used on premises. Having a common interface across all environments is a big advantage and provides a simpler, consistent management experience when deploying hybrid or heterogeneous cloud environments.
