Resource Allocation — Distributed Scheduler Architecture

Core Components

Allocation Manager

Responsibilities:
- Process allocation requests
- Apply scheduling policies
- Track resource usage
- Handle preemption
- Enforce quotas

Resource Tracker

Tracks:
- Available resources
- Allocated resources
- Resource utilization
- Tenant quotas
- Historical usage

Scheduler

Policies:
- Fair share scheduling
- Priority-based allocation
- Gang scheduling
- Backfilling
- Preemption logic

This architecture provides scalable, fair, and efficient resource allocation across distributed systems.
