Manage expenses in multiple cost centersYou can split expenses incurred by resources into various cost centers.In general, this applies to scenarios where you are required to manage expenses in multiple cost centers.

1. Allocate an instance to a cost center

After you allocate an instance to a cost center, all expenses incurred by the instance are linked to the cost center.

1

  • Step 1: In the Resources Not Allocated cost center, select an instance to be allocated.
  • Step 2: Click Allocate to select the target cost center.
  • Note:
    1. You can select multiple resources. After you click Submit, these resources are allocated to the new cost center.
    2. On the Cost Centers page, you can filter resources by multiple properties, such as the amount, instance ID, instance name (fuzzy search supported in a product category), tag, resource group, and payment method.

  • After you allocate resources to a cost center, the main account can view the number of accounts and the number of instances in the cost center. You can also view the information of the instances in the cost center. For more information about cost centers, see Manage cost centers. After an instance is allocated to a cost center, you cannot allocate the instance to another cost center.
  • Resources that you purchase require two or three days to be displayed in the Resources Not Allocated cost center. You can filter these resources by several properties, such as resource group and tag. In the Search field, you can only filter instances by instance ID. [DO NOT TRANSLATE]
  • An instance can only be allocated once. After an instance is allocated, you can transfer the instance to another cost center. However, the instance will be no longer displayed in the Resources Not Allocated cost center.

2. Remove an instance from a cost center

If an instance is allocated to a cost center, you cannot allocate the instance to another cost center.After you remove an instance from the previous cost center, you can reallocate the instance to another cost center. For more information about how to calculate expenses when an instance is reallocated, see the following rules.The procedure is similar to that of allocating an instance. Select a cost center where the required instance is located, click Remove, and then click OK to remove the instance from the cost center.

3. Split the total amount of expenses into multiple cost centers

Many types of product expenses are incurred by multiple resources. For example, the total expense of OSS consists of expenses incurred by a number of separate buckets. The total expense of CDN consists of expenses incurred by a number of separate domains. In general, buckets and domains are called linked resources.You can allocate the linked instances of a shared product to a cost center. This occurs when a cost center requires you to retrieve the part of its own expenses from the total amount of expenses and calculate this part. You can split the total expense of a product into multiple cost centers.

The procedure is the same as that of allocating normal resources.

  • Step 1: In the Product column, select the required resources.
  • Step 2: Allocate these resources to a cost center.

You can view the details of each splitting item that is related to a cost center in a splitting report on the next day. This occurs after you split the total expense of a shared product. For more information, see View splitting reports.

4. Rules for allocating resources to cost centers

Figure 1: Relationship between cost centers and instances2-5

    1. By default, unallocated instances are listed in the Resources Not Allocated cost center.
    1. After an instance is allocated to a cost center, the expenses of the instance are included in the next-day statistical data of the cost center. When you allocate an instance for the first time, expenses that are incurred by the instance after the allocation are linked to the cost center by default. If an instance was allocated to a cost center before Jan 1, 2018, expenses that were incurred from the day after the allocation time to Dec 31, 2017, are not linked to the cost center. However, expenses that were incurred on and after Jan 1, 2018, are linked to the cost center. If an instance was allocated to a cost center after Jan 1, 2018, expenses that were incurred from the day after the allocation time are linked to the new cost center.
    1. For a shared product, you must split the total expense of the product into multiple cost centers.
      • Supported products
      • CDN: can be divided into domains.
      • CBWP: can be divided into EIPs.
      • Snapshots: can be divided into ECS instances.
      • OSS: can be divided into buckets.
      • The rules for how to calculate expenses when you split the total expense of a shared product are the same as those when you allocate resources to cost centers.
    1. More rules: Available rules includes but are not limited to the preceding rules.
