Selecting an API Type

BMS APIs are classified as follows:

1. APIs for Huawei Cloud services with customized specifications (BMS APIs)
2. Native OpenStack APIs that comply with OpenStack community specifications

The two types of APIs offer similar functions but are used in different application scenarios. Native OpenStack APIs are used to meet open-source ecosystem requirements, while the APIs for the BMS service with customized specifications are developed based on Native OpenStack APIs with enhanced functions, such as creation of yearly/monthly BMSs and enterprise project management.

Currently, BMS APIs are v1 version, and the native OpenStack APIs are v2.1 version. To use native OpenStack APIs, you must be familiar with basic concepts and knowledge of OpenStack. For details, visit https://www.openstack.org/.
