• Load balancing with multiple servers

Scalability

AGI www.agiuc.com

• Client – STK 6.2 and up, STK 7 if using authentication

• Server (recommended)– Windows Server 2003

– 2+ GHz CPU

– 2 GB CPU memory

– 300+ GB storage

• This configuration serves roughly 10 to 25 simultaneous scenarios depending on:– Data complexity (3D terrain is more complex)

– Scenario dynamics

– Other bottlenecks (bandwidth, network hardware)
