Deployment unit in k8s is pod.

Pods are a model of the pattern of multiple cooperating processes which form a cohesive unit of service. They simplify application deployment and management by providing a higher-level abstraction than the set of their constituent applications. Pods serve as unit of deployment, horizontal scaling, and replication.
通过命令行kubectl get pods --all-namespaces查看运行的Kubernetes里的pod实例。

A deployment unit is a piece of software that can be operated on a separate ​​physical system​​, isolated from

other pieces of software. the SAP cloud solutions are organized in deployment units that group semantically

related business objects. For example, the Customer Relationship Management deployment unit groups

business objects such as Campaign, Lead, Opportunity, and Sales Order. The Foundation deployment unit

mainly contains master data objects, such as Material, Employee, and Customer.
