Namespace and Network
A namespace provides a method of allocating resources among multiple users. It applies to scenarios where multiple teams or projects exist.
A network is a resource object extended for CCI. You can associate a network with a Virtual Private Cloud (VPC) and its subnets so that CCI can use network resources of the public cloud.
Relationship Between Namespaces and Networks
As shown in Figure 1, when a namespace is created, the corresponding networks are created. In these networks, you can configure one or more subnets of a single VPC. Containers and other resources created in this namespace will run in the VPC and subnet you select.
If you want to run resources of multiple services in the same VPC, you need to consider network planning, including subnet CIDR block division and IP address planning.
Scenarios Where Multiple Namespaces Are Used
Because namespaces enable partial environment isolation, you can create different namespaces, such as production, test, and development namespaces based on project attributes when there are a large number of projects and persons.
