If you do not want to prepare server resources, Agora recommends using Agora Cloud Recording, which enables you to record voice/video calls and interactive broadcasts on your cloud storage through RESTful APIs.
The Agora On-premise Recording SDK is a component provided by Agora to record and save voice calls, video calls, and interactive broadcasts on your server. The Agora On-premise Recording SDK is compatible with the Agora Native SDK v1.7.0+ and the Agora Web SDK v1.12.0+.
For example, a user can either attend an online course at the time of the course or watch the recorded course later; made possible by the Agora On-premise Recording SDK being deployed at the server by the online course provider.
