Buying a DataArts Studio Instance

Context

• Only users with DAYU Administrator or Tenant Administrator permissions can buy DataArts Studio instances or incremental packages.
  NOTE:

  Users with Tenant Administrator permissions can perform all operations except IAM user management. For security purposes, you are not advised to grant Tenant Administrator permissions to IAM users.

• Only users with Security Administrator permissions can create cloud service agencies. Cloud service agencies allow DataArts Studio to perform operations such as task scheduling and resource O&M on other cloud services on your behalf.

Prerequisites

You have obtained a VPC, subnet, and security group. You can also apply for them when you buy a DataArts Studio instance.

For details, see Virtual Private Cloud User Guide.

Logging In to the DataArts Studio Console

1. Log in to the Huawei Cloud console.
2. In the upper left corner of the console, click , and choose to access the DataArts Studio console.

buy a DataArts Studio Basic Package

1. Go to the package for buying a DataArts Studio instance.
2. On the displayed page, set the parameters listed in Table 1.

   Table 1 DataArts Studio instance parameters

   Parameter	Example Value	Description
   Region	N/A	Region where the instance resides. Resources in different regions cannot communicate with each other. When selecting a region, consider the following factors: Location Select a region close to you or your target users. This reduces network latency and accelerates access. Relationship between cloud services Cloud services in different regions cannot communicate with each other through an internal network. For example, if you want to enable communication between DataArts Studio (containing modules such as Management Center and CDM) and services in other regions (such as MRS and OBS), use a public network or Direct Connect. If DataArts Studio and the other services are in the same region, instances in the same subnet and security group can communicate with each other by default. Resource price Resource pricing may vary in different regions. For details, see Product Pricing Details. For details, see Regions and AZs.
   Enterprise Project	default	Enterprise project associated with the default workspace of the DataArts Studio instance. An enterprise project facilitates management of cloud resources. For details, see Enterprise Management User Guide. This parameter is available only when an enterprise project has been created. If you want to connect the DataArts Studio instance to an instance of another cloud service, such as GaussDB(DWS), MRS, and RDS, ensure that the enterprise project of the DataArts Studio instance's workspace is the same as that of the target cloud service instance. You can buy only one DataArts Studio instance for an enterprise project. If you want to enable communication between DataArts Studio and another cloud service, ensure that the enterprise project of DataArts Studio is the same as that of the target cloud service. NOTE: If the enterprise project function is not enabled, only one DataArts Studio instance can be created for each IAM project.
   Version	Starter	Select a DataArts Studio version. For details about the differences between versions, see Versions. NOTE: When you purchase a DataArts Studio instance, you will also get a Cloud Data Migration (CDM) cluster. You are advised to use this CDM cluster as a connection agent. To migrate data, buy a CDM incremental package with higher specifications. For details, see Buying a DataArts Migration Incremental Package.
   Billing Mode	Yearly/Monthly	The DataArts Studio basic package only supports the yearly/monthly billing mode.
   Instance Name	DataArts Studio-test	Name of the DataArts Studio instance. After the instance is created, its name cannot be changed.
   AZ	AZ1	AZ of the DataArts Studio instance, that is, the AZ where the CDM cluster is located. The DataArts Studio instance communicates with other services through the CDM cluster. When you buy your first DataArts Studio instance or incremental package, you can select any available AZ. When you buy another DataArts Studio instance or incremental package, determine whether to select the same AZ as that for the first instance or package based on your DR and network latency demands. If your application requires good DR capability, deploy resources in different AZs in the same region. If your application requires a low network latency between instances, deploy resources in the same AZ. For details, see Regions and AZs.
   VPC	vpc1	VPC, subnet, and security group to which the CDM cluster in the DataArts Studio instance belongs. The DataArts Studio instance communicates with other services through the CDM cluster. If you want to connect the DataArts Studio instance or CDM cluster to a cloud service such as GaussDB(DWS), MRS, and RDS, ensure that the CDM cluster can communicate with the cloud service. If the CDM cluster and the cloud service are in the same region, VPC, subnet, and security group, they can communicate with each other by default. If the CDM cluster and the cloud service are in the same VPC but in different subnets or security groups, you must configure routing rules and security group rules. For details about the operations on VPCs, subnets, and security groups, see Virtual Private Cloud User Guide. NOTE: After a DataArts Studio instance is created, the VPC, subnet, and security group of the default CDM cluster cannot be changed. Set them properly when creating the DataArts Studio instance. You can select a VPC subnet shared by the VPC owner when you buy a DataArts Studio instance. Through VPC subnet sharing, you can easily configure and manage multiple accounts' resources at low costs. For details about how to share a VPC subnet, see VPC Sharing.
   Subnet	subnet-1
   Security Group	sg-1
   Required Duration	1 year	Select a duration based on your needs.
   Auto-renew	N/A	You can select Auto-renew to enable automatic renewal of the subscription by month or by year. If you choose the monthly billing mode, your subscription will be automatically renewed each month. If you choose the yearly billing mode, your subscription will be automatically renewed each year.
   Tags	Tag key: key1 Tag value: asd	You can add resource tags to classify resources. NOTE: If your account belongs to an organization and the organization has configured DataArts Studio tag policies, you need to add tags based on these policies. If a tag does not comply with the tag policies, instance creation may fail. Contact your administrator to learn more about tag policies. DataArts Studio instance tags can be used in the following scenarios: If there are a large number of cloud resources, you can add tags to them (including DataArts Studio instances) by user, maintainer, or usage. Then you can use Tag Management Service (TMS) to identify tags and manage cloud resources easily. If there are multiple DataArts Studio instances, you can add tags to them by user, maintainer, or usage. Then you can search for and identify DataArts Studio instances by tag on the DataArts Studio instance list page. A tag consists of a key and a value. When adding a tag, you can select a predefined tag created in Tag Management Service (TMS) or enter a custom tag. Then click Add to the right of the text box to add the tag. NOTE: To select predefined tags, ensure that you have created predefined tags in TMS. You can click View predefined tags to enter the Predefined Tag page of TMS. Then, click Create Tag to create a predefined tag. For details, see Creating Predefined Tags in Tag Management Service User Guide. A maximum of 20 tags can be added to a DataArts Studio instance. Each tag key must be unique and can only match one tag value.

5. When you return to the DataArts Studio console, the Authorize Access dialog box is displayed, prompting you to authorize the listed services. DataArts Studio interacts with these cloud services. You must create a cloud service agency to delegate permissions to DataArts Studio so that DataArts Studio can use these cloud services and perform task scheduling and resource O&M on your behalf.
   NOTICE:

   Only users with Security Administrator permissions can create cloud service agencies. Cloud service agencies allow DataArts Studio to perform operations such as task scheduling and resource O&M on other cloud services on your behalf.

   Cloud service agencies include permissions related to DWS, MRS, RDS, OBS, SMN, and KMS. You can access the IAM agency page to view the agency scope. You do not need to apply for an agency for users. The agency of the account is used.

   Select all services and click Authorize. The system automatically creates the default dlg_agency.

   • After the authorization is complete, the Authorize Access dialog box will not be displayed when you access the DataArts Studio console homepage next time.
   • If you select only some services for authorization, this dialog box will be displayed again next time you access the DataArts Studio console, prompting you to authorize access to the unauthorized cloud services.
