Given Task 5¶

  1. Scalability and Cost Management

    • Develop a plan for scaling the system to handle a large number of concurrent tasks and agents.
    • Implement basic cost management strategies to optimise resource usage (e.g., agent pooling, task prioritisation).
    • Provide a brief analysis of potential bottlenecks and proposed solutions.
