CTS service management APIs are open to tenants. Tenants can create a tracker for provisioning the CTS service or manage the tracker through the API. Tenants can use the trace query API to query other cloud service operations generated within recent seven days. API Gateway controls whether CTS APIs are open to tenants, and tenants access CTS APIs through API Gateway. The following figure shows the CTS APIs.
API Gateway only checks parameter validity of APIs and does not convert models to ensure that Open Telekom Cloud APIs are compatible with native OpenStack APIs. However, Combined API encapsulates and enhances cloud service APIs. The enhanced APIs are independent of native OpenStack APIs and do not affect native OpenStack API compatibility.
API Gateway, as the access gateway for OpenStack APIs and Combined API, is in charge of external access control of API capabilities. For example:
API Gateway controls whether APIs are published by API registration.
For security purposes, the CTS service limits the total times users can call the open APIs within a specified period. The API flow control methods are as follows:
To improve system security when users call CTS APIs and use the CTS service, API Gateway provides monitoring and operation logs to assist O&M and analysis. These logs are open to O&M personnel currently.
