bookHow Cloud Pricing Really Works

When you use cloud platforms like AWS, Azure or Google Cloud, understanding how pricing works is crucial for keeping costs under control. All major cloud providers offer flexible pricing models, but the details can be confusing if you do not know what to look for. Three main pricing structures dominate: pay-as-you-go, reserved, and spot pricing. Each has its own advantages and trade-offs.

Pay-as-you-go Pricing

Pay-as-you-go is the default and most flexible model. You are charged only for what you use, with no upfront commitments. This is ideal for unpredictable workloads or when you are just starting out. However, the convenience comes at a higher per-unit cost.

Reserved Pricing

Reserved pricing lets you commit to using certain resources for a set period, usually one or three years. In exchange for this commitment, you receive a significant discount compared to pay-as-you-go rates. This model works best for stable, predictable workloads where you know you will need the same resources over time.

Spot Pricing

Spot pricing (sometimes called preemptible or auction-based instances) allows you to bid on unused capacity at steep discounts. The catch is that your resources can be interrupted or reclaimed at any time, making this option best for flexible, non-critical tasks like batch processing or testing.

While these models are available across all major providers, the exact terms and discounts may vary. It is important to compare options and understand the implications for your workloads.

Cloud billing is metered based on your actual usage, but there are important details to watch. Most services now offer per-second billing, so you only pay for the time resources are running. However, there may be minimum charges for example, a minimum of one minute or one hour for certain services, even if you use less.

Note

Many providers advertise a free allowance for new accounts or certain services. While this can be useful, it is easy to accidentally exceed these limits and incur unexpected charges. Always monitor your usage closely and understand the thresholds.
