Resource Planning for the Target Cluster

CCE allows you to customize cluster resources to meet various service requirements. Table 1 lists the key performance parameters of a cluster and provides the planned values. You can set the parameters based on your service requirements. It is recommended that the performance configuration be the same as that of the source cluster.

After a cluster is created, the resource parameters marked with asterisks (*) in Table 1 cannot be modified.

**Table 1** Example of CCE cluster planning
Resource	Key Performance Parameter	Description	Example Value
Cluster	*Cluster Type	CCE supports multiple cluster types to meet diverse needs, including highly reliable, highly secure, commercial containers. You can select CCE Standard Cluster or CCE Turbo Cluster as required. For more details, see Comparison Between Cluster Types.	CCE standard cluster
	*Network Model	Select VPC network or Tunnel network for your CCE standard cluster. For details about the differences between container network models, see Container Networks.	VPC network
	*Number of master nodes	Select the number of master nodes, also known as control plane nodes. These nodes are hosted on CCE and run Kubernetes components like kube-apiserver, kube-controller-manager, and kube-scheduler. 3 Masters: Three master nodes will be created to ensure high availability. Single: Only one master node will be created in your cluster.	3 Masters
Node	Node Type	Select a node type based on service requirements. The available node flavors will then be displayed in the Specifications area for you to choose from.	Elastic Cloud Server (VM)
	Node Specifications (vary depending on the actual region)	Select a node flavor that best fits your service needs. For optimal cluster component performance, you are advised to choose a node with at least 4 vCPUs and 8 GiB of memory.	4 vCPUs \| 8 GiB
	OS	Select an OS for the nodes.	EulerOS
	System Disk	System disk used by the node OS. The value ranges from 40 GiB to 1024 GiB. The default value is 50 GiB.	50 GiB
	Data Disk	Add a data disk for container runtime and kubelet. The disk size ranges from 20 GiB to 32768 GiB. The default value is 100 GiB.	100 GiB
