 Cloud LoadMaster MAX -  VLM-500 - Kemp




  • Uncapped Throughput
  • Uncapped SSL Transactions Per Second (TPS)
  • Supports Up to 1,000 Virtual IPs (VIP) and 1,000 Real IPs (RIP)
  • Performance dependent on allocated system resources



Virtual & Cloud 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 with advanced authentication and traffic delivery options. 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 metered licensing across multiple Virtual LoadMaster instances. Metered licensing provides the flexibility to deploy and retire load 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 and PowerShell) enables automation of load balancer deployment, configuration and administration and integration of load 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 application delivery demands change for maximum flexibility. The tiers are mapped to common customer challenges and requirements, 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.
