Buying a DataArts Studio Basic Package

Background

• Only users who have the DAYU Administrator or Tenant Administrator permissions can buy DataArts Studio instances or DataArts Studio incremental packages. To allow users to buy instances or incremental packages, you must grant the required permissions to them.
  

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

• Only users who have the 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 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 DataArts Studio Console

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

Buying a DataArts Studio Basic Package

1. Access the page for purchasing a DataArts Studio instance.
2. On the displayed page, set parameters for the DataArts Studio instance. Table 1 provides descriptions of the parameters.

   Table 1 DataArts Studio instance parameters

   Parameter	Example	Description
   Region	None	The region where the instance resides. Resources in different regions cannot communicate with each other. When selecting a region, consider the following factors: Location You are advised to select a region closest to your target users. This reduces network latency and improves access rate. However, Chinese mainland regions provide the same infrastructure, BGP network quality, and operations and configurations on resources. Therefore, if your target users are in the Chinese mainland, you do not need to consider the network latency differences when selecting a region. The countries and regions outside the Chinese mainland, such as Bangkok, provide services for users outside the Chinese mainland. If your target users are in the Chinese mainland, these regions are not recommended because there may be a latency in accessing resources. 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 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 a cloud service (such as DWS, MRS, and RDS), ensure that the enterprise project of the DataArts Studio workspace is the same as that of the 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 cloud service.
   Version	Basic	Select a DataArts Studio version. For details about the version differences, see Versions. NOTE: The DataArts Studio instance contains a CDM cluster by default. You are advised to use this cluster as a connection agent. For data migration jobs, purchase a DataArts Migration incremental package of a higher version. For details, see Buying a DataArts Migration Incremental Package.
   Billing Mode	Yearly/Monthly	The DataArts Studio basic package is billed on a monthly/yearly basis.
   Instance Name	DataArts Studio-test	Name of the DataArts Studio instance The instance 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 a DataArts Studio instance or incremental package for the first time, there is no requirement on the AZ. When you buy a new DataArts Studio instance or incremental package, determine whether to select the same AZ as the existing one 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 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 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. Exercise caution when setting them during the instance creation. 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 requirements.
   Auto-renew	N/A	You can select Auto-renew to automatically renew 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.
   Tag	Tag key: key1 Tag value: asd	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. You can set tags when creating a DataArts Studio instance. Enter a tag key in the text box or select a predefined tag key from the drop-down list. NOTE: To add a predefined tag, you need to create one on TMS and then select it from the Tag key drop-down list. 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. Enter a tag value in the text box or select a predefined tag value from the drop-down list. Click Add to add the tag. NOTE: A maximum of 20 tags can be added. Only one tag value can be added to a tag key. The key name must be unique in the same instance.

3. Confirm the settings and click buy Now.
4. Click Next. After you pay for your instance, wait until the instance is created. The created instance is displayed on the homepage.

5. When you return to the DataArts Studio management console, the Authorize Access dialog box is displayed, prompting you to authorize the listed services. DataArts Studio interacts with the cloud services and needs to collaborate with them. Therefore, you need to 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 behalf of you.
   

   Only users who have the 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 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 platform automatically creates the default agency 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, the system still displays the dialog box next time you access the DataArts Studio console homepage, prompting you to authorize access to unauthorized cloud services.
