Answer: Amazon EC2 On-Demand Instances
## Explanation Amazon EC2 On-Demand Instances are the most appropriate choice for this scenario because: - **Variable workload pattern**: The application has an irregular usage pattern - running for a few hours most days, but with significantly higher usage (8 hours daily) for one week each month - **Cost efficiency**: On-Demand instances are billed by the second with no long-term commitment, making them ideal for workloads with unpredictable or variable usage patterns - **Flexibility**: No need to predict capacity requirements in advance, which aligns with the fluctuating monthly workload - **No wasted costs**: Unlike Reserved Instances which require upfront payment and are better for steady-state workloads, On-Demand instances avoid paying for unused capacity during low-usage periods **Why not the other options:** - **Amazon EC2 Standard Reserved Instances**: Better suited for steady-state workloads with predictable usage, not variable patterns - **AWS Wavelength**: Designed for ultra-low latency applications at the edge, not relevant for this general compute scenario - **Application Load Balancer**: A networking service for distributing traffic, not a compute hosting solution The selected answer "Amazon EC2 On-Demand Instances" is correct.
