 KubeVela revolves around cloud-native application delivery and management scenarios. The application delivery model behind it is [Open Application Model](../platform-engineers/oam/oam-model), or OAM for short. It describes various components and operational traits required for application as a unified, and infrastructure-independent "deployment plan". As a result, we can achieve standardized and efficient application delivery in a multi-cloud/hybrid-cloud environment. KubeVela includes the following core concepts:
