This document describes how you will be billed for using OBS, including the billing items and billing modes. For the pricing about the Parallel File System (PFS), see Product Pricing Details.
OBS provides two billing modes: pay-per-use and yearly/monthly. Pay-per-use is recommended if you are unsure of your future service needs and want to avoid paying for unused resources. If you are sure of your needs, yearly/monthly will be less expensive.
You are billed for using OBS on a pay-per-use basis by default. With this billing mode, you pay only for how long (hours) you actually use the resources. There is no minimum cost. For details, see Pay-per-Use.
You can also purchase a yearly/monthly resource package for a cheaper price. However, if your usage exceeds the package quota, subsequently used resources will be charged on a pay-per-use basis. For details, see Resource Package Overview.
