Overview

There are yearly/monthly and pay-per-use billing modes. Each one has different advantages and disadvantages.

  • Yearly/Monthly is a prepaid billing. You pay in advance for a subscription term, and in exchange, you get a discounted rate. The longer the subscription term, the bigger the discount. Yearly/Monthly billing is a good option for long-term, stable services.
  • Pay-per-use is a postpaid billing mode. You pay as you go and just pay for what you use. The DRS usage is calculated by the second but billed every hour. This mode allows you to adjust resource usage easily. You do not need to prepare resources in advance, and will not have excessive or insufficient preset resources.

Table 1 lists the differences between the two billing modes.
