KEMP Technologies LoadMaster capabilities for the increasing LoadMaster Application Delivery Controller and segment of remote workers. products are Server Load Balancer appliances "RDP-aware", provide full support for Microsoft Application Delivery Controllers meaning they can Windows Terminal Services (WTS). Application delivery solutions were intelligently load The LoadMaster WTS capabilities built to address the challenges balance between helps organizations maximize the associated with website Terminal Servers, efficiency and effectiveness of their infrastructure complexity, and integrate with networks. KEMP delivers this at an performance, scalability and security. TS Session affordable price. They may be known as application Directory.
The LoadMaster resource monitoring delivery controllers (ADC),

In addition, by using various load accessible via HTTP by the load balancing algorithms, an ADC can balancers. The script ran on each distribute users to servers that offer host, and generated a number from the best possible performance. The 1 to 100. Then the load balancer ADC can dynamically interrogate key would check http://host1/myscript, server elements such as the number http://host2/myscript to determine of concurrent connections and which server should receive the new CPU/memory utilization. load. To further enhance, and secure the This was not the most ideal solution, user experience, more-advanced but it was flexible, since you could ADCs provide SSL use any perfmon counter, WMI offload/acceleration. SSL interface, EXE, etc. to generate the acceleration in the ADC enables you numbers. For example, you could to offload the SSL handshake and create a script that ran several encryption/decryption processes checks for websites, and sample from the servers. This offloading database queries. If everything came dramatically increases the servers' back as expected, it would generate performance, while decreasing the a loa... [download for more]
