Managing Basic Resources

Prerequisites

The following basic resources to be managed have been created:

• The ECSs to be managed have been created and are in the running state. The ECSs must be in the same VPC as the target environment and cannot be managed by other environments.

  ECSs are used to deploy and run components on VMs. For details about how to create ECSs, see Purchasing a Custom ECS.

• The AS groups to be managed have been created. The AS groups must be in the same VPC as the target environment and cannot be managed by other environments. In addition, the AS groups contain ECSs.

  AS groups are used to deploy and run components on VMs. For details about how to create AS groups, see Creating an AS Group.

• The load balancers to be managed have been created. The load balancers must be in the same VPC as the target environment.

  Load balancers are used to access services provided by components in ELB mode or perform ELB dark launch. Create a load balancer based on the actual application scenario.

  Use the domain name to access an application.	Creating a Shared Load Balancer. See Creating a Dedicated Load Balancer.
  ELB dark launch	See Creating a Dedicated Load Balancer.

• The EIPs to be managed have been created.

  EIPs are used to access services provided by a component through public network. For details about how to create EIPs, see Assigning an EIP.

• The DCS instances to be managed have been created. The DCS instances must be in the same VPC as the target environment.

  DCS instances are used to read environment variables to obtain distributed cache information during application running. For details about how to create DCS instances, see Buying a DCS Redis Instance.

• The RDS MySQL DB instances to be managed have been created. The RDS instances must be in the same VPC as the target environment.

  RDS instances are used for persistent storage of application data. For details about how to create RDS instances, see Step 1: Buy a DB Instance.

• The ServiceComb engines (microservice engines, see Cloud Service Engine Overview) to be managed have been created. If the microservice engines and the environment are in different VPC, correctly configure the VPC connectivity.

  Microservice engines are used to connect microservices running in the environment to the engine to implement microservice registry and discovery, service governance, and configuration management. For details, see Creating a Microservice Engine.

Managing Basic Resources

1. Log in to ServiceStage.
2. On the Environment Management page, click the target environment.
3. In the left pane of the Resources tab, manage resources in the environment by referring to the following table.

   Resource Type	Resource Name	Operation
   Compute	Clusters	See Binding a CCE Cluster. CCE clusters can be bound to a Kubernetes environment. To manage CCE clusters in the environment, see Managing CCE Resources.
   	ECSs	Choose Compute > ECSs. Click Manage Resource. Select the ECSs to be managed. Click OK. NOTE: ECSs can be managed in a VM environment. In the same VPC, ECSs that have been managed by other environments cannot be managed again. If Agent Status of the managed ECSs indicates that the agent is missing and to install it first, install the agent. For details, see Installing a VM Agent.
   	AS Groups	Choose Compute > AS Groups. Click Manage Resource. Select the AS groups to be managed. Click OK. NOTE: AS groups can be managed in a VM environment. In the same VPC, AS groups that have been managed by other environments cannot be managed again. If Agent Status of the ECSs of the managed AS groups indicates that the agent is missing and to install it first, install the agent. For details, see Installing a VM Agent.
   Networking	Load Balancers	Choose Networking > Load Balancers. Click Manage Resource. Select the load balancers to be managed. Click OK.
   	VPC EIPs	Choose Networking > VPC EIPs. Click Manage Resource. Select the EIPs to be managed. Click OK.
   Middleware	DCS Instances	Choose Middleware > DCS Instances. Click Manage Resource. Select the DCS instances to be managed. Click OK.
   	ServiceComb Engines	Choose Middleware > ServiceComb Engines. Click Manage Resource. Select the ServiceComb engines to be managed. Click OK.
   	RDS Instances	Choose Middleware > RDS Instances. Click Manage Resource. Select the RDS instances to be managed. Click OK.
