Enterprise Application Scaling of Terminal Services on Microsoft Windows Server 2003 64 Bit
eKnowlogy worked with Scapa Technologies and a broad range of technology partners to prove the scalability of an enterprise application running under Terminal Services on the 64 Bit version of Microsoft Windows Server 2003.
Scapa Test and Performance Platform was used to analyse the performance of the entire solution: application publishing, load balancing, security, operating system, and application, confirming the viability of a native Terminal Services approach to this high-profile application deployment.
Conventional wisdom suggests that a native Terminal Services solution would struggle in a deployment of this scale. However, a combination of 64 Bit hardware and a 64 Bit Operating system was proved to operate together to provide a highly scalable and secure solution at a significantly reduced cost over competitive approaches, without any modification to the existing 32 Bit application.
The 64-bit version of Microsoft Terminal Services was shown to scale to 200 concurrent users on a single server, 3 times as many concurrent users as the 32 bit version, and to deliver 2.6 times the number of business transactions per second. The corresponding reduction in the number of physical servers significantly reduces the overall complexity and cost of the solution.
Of particular interest is the effectiveness of the 64-bit Terminal Services memory management architecture in breaking through the long-standing 32-bit physical limits.
