how to create resource scenarios - Resource Orchestration Service

You can create four types of resource scenarios in Resource Orchestration Service (ROS): resource replication, resource management, resource migration, and resource detection.

Create a resource replication scenario

Log on to the ROS console.
In the left-side navigation pane, click Scenarios.
In the top navigation bar, select a region from the drop-down list.
On the Scenarios page, click Create Scenario.
In the Create Scenario dialog box, enter a description and select Resource Replication as the scenario type.
Select the resource scope.
- Select resources by tag
  1. In the Method section, select Source Tag.
  2. In the Source Tag section, set the Tag Key and, optionally, the Tag Value.
    
    Note
    Enter the tags of your existing resources. You can specify up to 10 tags.
  3. (Optional) In the Resource Type section, select one or more Resource Types.
    
    You can select up to 15 resource types.
- Select resources by resource group
  1. In the Method section, select Source Resource Group.
  2. In the Source Resource Group section, select a resource group.
  3. (Optional) In the Resource Type section, select one or more Resource Types.
    
    You can select up to 15 resource types.
- Select specific resources
  1. In the Method section, select Source resource.
  2. In the Source resource section, select a Resource Types and a Resource ID.
    
    You can select up to 20 resource types.

Configure the destination parameters.

Parameter	Description
Delete Resource	Specifies what happens to the source resources when you delete the replicated stack. Valid values: Retain: Retains the source resources when you delete the replicated stack. Delete: Deletes the source resources by default when you delete the replicated stack. In the deletion confirmation dialog box, you can choose which resources to retain. ROS deletes any resources that you do not select.
Destination Region	The region where the resources are replicated. By default, the current region is used.
Destination Zone	The destination availability zone for the replicated resources. If you replicate resources within the same region, ROS uses the source availability zone by default. If you replicate resources across regions, ROS automatically selects an availability zone.
Destination VPC	The destination Virtual Private Cloud (VPC) for the replicated resources. If you replicate resources within the same region, ROS uses the source VPC by default. If you replicate across regions, ROS automatically creates a new VPC. Note Ensure that the CIDR block of the destination VPC does not overlap with the CIDR block of the source VPC.
Destination vSwitch	The destination vSwitch for the replicated resources. If you replicate resources within the same region, ROS uses the source vSwitch by default. If you replicate across regions or to a specific destination VPC, ROS automatically creates a new vSwitch. Note Ensure that the CIDR block of the destination vSwitch does not overlap with the CIDR block of the source vSwitch.
Replicate ECS Instance Data	This parameter is available only if the source resources include an ECS instance. To ensure data consistency, stop the source ECS instance before you replicate the instance data.
Tags	You can add tags to or remove tags from resources. Note Each resource can have up to 20 tags.

Click Create.

After the resource scenario is created, its Status changes to Created.

Create a resource management scenario

Log on to the ROS console.
In the left-side navigation pane, click Scenarios.
In the top navigation bar, select the region where your resources are located from the region drop-down list.
On the Scenarios page, click Create Scenario.
In the Create Scenario dialog box, enter a description for the scenario and select Resource Management as the scenario type.
Select the resource scope.
- Select resources by tag
  1. In the Method section, select Source Tag.
  2. In the Source Tag section, set the Tag Key and, optionally, the Tag Value.
    
    Note
    Enter the tags of your existing resources. You can specify up to 10 tags.
  3. (Optional) In the Resource Type section, select one or more Resource Types.
    
    You can select up to 15 resource types.
- Select resources by resource group
  1. In the Method section, select Source Resource Group.
  2. In the Source Resource Group section, select a resource group.
  3. (Optional) In the Resource Type section, select one or more Resource Types.
    
    You can select up to 15 resource types.
- Select specific resources
  1. In the Method section, select Source resource.
  2. In the Source resource section, select a Resource Types and a Resource ID.
    
    You can select up to 20 resource types.
In the configuration section, set the Delete Resource.
- Retain: Resources are kept when their stack is deleted.
- Delete: Resources are deleted by default when their stack is deleted. If you choose to retain specific resources in the confirmation dialog, ROS deletes only the unselected resources.
Set tags for the resource scenario.

Note
You can add up to 20 tags to the resource scenario.
Click Create.

After the resource scenario is created, its Status changes to Created.

Create a resource migration scenario

Log on to the ROS console.
In the left-side navigation pane, click Scenarios.
In the top navigation bar, select a region where you want to create the resource scenario from the region drop-down list.
On the Scenarios page, click Create Scenario.
In the Create Scenario dialog box, enter a description for the resource scenario and select Resource Migration as the scenario type.
Select the resource scope.
- Select resources by tag
  1. In the Method section, select Source Tag.
  2. In the Source Tag section, set the Tag Key and, optionally, the Tag Value.
    
    Note
    Enter the tags of your existing resources. You can specify up to 10 tags.
  3. (Optional) In the Resource Type section, select one or more Resource Types.
    
    You can select up to 15 resource types.

In the Configure Scenario section, configure parameters for resources that you want to migrate.

Parameter	Description
Destination Region	The destination region of the resources. By default, the region of the source resources is used.
Destination Zone	The destination zone of the resources. By default, if you migrate resources within the same region, the zone of the source resources is used. If you migrate resources across regions, the system automatically selects a zone.
Destination VPC	The destination virtual private cloud (VPC) of the resources. By default, if you migrate resources within the same region, the VPC of the source resources is used. If you migrate resources across regions, the system automatically creates a VPC. Note Make sure that the VPC CIDR blocks of the migrated resources contain the VPC CIDR blocks of the source resources.
Destination vSwitch	The destination vSwitch of the resources. By default, if you migrate resources within the same region, the vSwitch of the source resources is used. If you migrate resources across regions, the system automatically creates a vSwitch. Note Make sure that the vSwitch CIDR blocks of the migrated resources contain the vSwitch CIDR blocks of the source resources.
Replicate ECS Instance Data	This parameter takes effect only if the source resources contain an Elastic Compute Service (ECS) instance. If you select Replicate ECS Instance Data, ROS replicates the data on the ECS instance. To ensure data consistency, you must stop the source ECS instance before ROS replicates the instance data.
Tags	You can add tags to or remove tags from resources. Note You can add up to 20 tags to each resource.

Click Create.

After the resource scenario is created, its Status changes to Created.
