Which Amazon Bedrock pricing model is recommended for flexibility without long-term commitment?

1. A. On-Demand

2. B. Model customization

3. C. Provisioned Throughput

4. D. Spot instance

The correct answer is: A. On-Demand

The recommended pricing model for flexibility without long-term commitment in Amazon Bedrock is the On-Demand option. This model allows users to pay for the resources they consume without needing to commit to a specific usage agreement or contract duration. It is ideal for scenarios where workloads may vary, as it provides the ability to scale resources up or down based on current needs. This flexibility is particularly advantageous for businesses and developers who are experimenting with different models or workloads, as it allows them to quickly adapt to changing requirements and budget considerations without being tied to a long-term commitment. Users can turn services on or off and only incur costs while actively using the resources, which is not something that would be feasible under more rigid pricing structures. In contrast, other options like model customization or provisioned throughput often imply a level of commitment or upfront configuration, which may not suit every scenario, particularly for teams looking to innovate or test rapidly. The Spot instance pricing model, while cost-effective, involves a degree of unpredictability as it relies on spare capacity, which may not be suitable for all applications that require consistent availability.
