Estimating Costs

Last updated: 2021-12-13 16:02:15

    Other than your CVM model and VPC configuration, these factors also influence how much your service costs:

    • Billing method
    • Resource used
    • Quantity

    Billing method

    • Pay as you go is a flexible billing method for CVM instances. You can launch/terminate a CVM at any time and are billed by the actual usage of the CVM. You pay by the second and no up-front payment is required. A bill is generated every hour on the dot. This billing method is suitable for use cases such as an e-commerce flash sale where the demand for resources can fluctuate greatly.
    • Spot Instance is a new way to use and pay for CVM instances. Similar to Pay as you go, you pay for Spot Instances by the second, every hour. The price of Spot Instances fluctuates according to market demand. You get a sizable discount for them when the demand is low (usually 10 to 20%). However, they might be repossessed automatically by the system as the demand becomes high.

    The number of CVMs you purchase also affects the price you pay. More CVMs means a higher price.
