• Server upgrades
• Additional data storage
• 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)
