This article discusses key considerations for choosing between single-session and multi-session fleets on Amazon AppStream 2.0. It provides insights on how this decision impacts factors like use case, cost, security, and performance.

Specifically, the article covers:

• Use Case: Single-session fleets are better for resource-intensive applications or unpredictable workloads, while multi-session fleets are ideal for light or predictable workloads and sharing GPU resources.
• Cost: Multi-session fleets reduce overhead, but underutilized instances can diminish cost savings. Known usage patterns and maximizing utilization are crucial for cost-effectiveness.
• Security: Single-session fleets offer instance-level segregation, while multi-session fleets rely on OS-level isolation and require careful configuration for sensitive environments.
• Performance: Single-session fleets ensure dedicated resources and consistent performance, while multi-session fleets can suffer from the "noisy neighbor" effect and require monitoring and optimization.
• Conclusion: The optimal choice depends on various factors, and administrators must carefully evaluate their requirements and trade-offs for each scenario.
