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.
