CCE works with the following cloud services and requires permissions to access them.

Figure 1 Relationships between CCE and other services

**Table 1** Relationships between CCE and other services
Service	Relationship
ECS	An ECS with multiple EVS disks is a node in CCE. You can choose ECS specifications during node creation.
VPC	For security reasons, all clusters created by CCE must run in VPCs. When creating a namespace, create a VPC or bind an existing VPC to the namespace so all containers in the namespace will run in this VPC.
ELB	CCE works with ELB to load balance a workload's access requests across multiple pods.
NAT Gateway	The NAT Gateway service provides source network address translation (SNAT), which translates private IP addresses to a public IP address by binding an elastic IP address (EIP) to the gateway.
SWR	An image repository is used to store and manage Docker images.
EVS	EVS disks can be attached to cloud servers and scaled to a higher capacity whenever needed. An ECS with multiple EVS disks is a node in CCE. You can choose ECS specifications during node creation.
OBS	OBS provides stable, secure, cost-efficient, and object-based cloud storage for data of any size. With OBS, you can create, modify, and delete buckets, as well as uploading, downloading, and deleting objects. CCE allows you to create an OBS volume and attach it to a path inside a container.
AOM	AOM collects container log files in formats like .log from CCE and dumps them to AOM. On the AOM console, you can easily query and view log files. In addition, AOM monitors CCE resource usage. You can define metric thresholds for CCE resource usage to trigger auto scaling.
