Virtual LoadMaster – Datasheet

Cloud & Virtual Application Delivery
Kemp’s Virtual LoadMaster is a fully featured load balancer and application delivery controller (ADC) that supports all
the major application workloads with easy-to-use templates. It offers key features such as SSL offload along withadvanced authentication and traffic delivery options.

Figure 1- LoadMaster Hybrid Topology

Deliver Anywhere
Virtual LoadMaster (VLM) instances can be deployed on all major hypervisors and on leading public cloud services
with a consistent set of features regardless of where deployed. Consistency across a wide range of platforms greatly
simplifies cloud migration and hybrid cloud deployments with seamless migration and reduced management
complexity.

Flexible Licensing
Virtual LoadMaster can be licensed using permanent or subscription licenses on each instance, or with meteredlicensing across multiple Virtual LoadMaster instances. Metered licensing provides the flexibility to deploy and retireload balancing resources on-demand, greatly simplifying DevOps environments and application scaling.

Easily Managed
Regardless of where Virtual LoadMasters are deployed, a consistent administration interface is presented via Web UI,
API and Kemp 360 Central. Kemp 360 Central provides cross-platform configuration and monitoring of load balancing
resources to simplify the administration of multi-load balancer environments. The LoadMaster API (RESTful andPowerShell) enables automation of load balancer deployment, configuration and administration and integration ofload balancer operations with DevOps and hypervisor management frameworks.

Support Subscriptions
LoadMaster support subscriptions offer flexibility, simplicity and value to meet your application delivery
requirements and challenges. Support subscriptions are annual and can be upgraded and downgraded as applicationdelivery demands change for maximum flexibility. The tiers are mapped to common customer challenges andrequirements, simplifying the task of selecting the appropriate feature set and support levels.
LoadMaster annual subscriptions (VLM-500, VLM-3000 and VLM-MAX) and cloud (AWS & Azure) pay-as-you-go include
an Enterprise Plus support subscription as standard.
