Efficiency of Distributed Systems

Design a distributed system that improves both network utilization and end-to-end processing throughput. Explain the proposed architecture, the technologies you would select, and how the system would manage resources and assign work across its nodes.

High-level architecture of the distributed job processing system across regions

Constraints

• The design must support multiple geographic regions.
• Work should be distributable across independent worker nodes.
• The system should account for both network bandwidth and compute capacity when placing tasks.
• A single node or regional failure must not stop all processing.
• The design must explain how tasks are queued, scheduled, monitored, retried, and reassigned when necessary.
• The technology stack and its role in the architecture must be identified.
