1.1 Introduction
                 Cost Center offers a suite of tools for free that help you track, analyze, and
                 explore your HUAWEI CLOUD costs and usage.
                 Currently, the tools include:
                 ●      Cost Analysis: presents cost in charts. You can view your HUAWEI CLOUD
                        costs and usage of different billing cycles and dive deeper by service type,
                        region, linked account, billing mode, and cost tag.
                 ●      Budgets: allows you to configure budgets and stay informed of how your cost
                        and usage progress.
                 ●      Reports: allows you to learn about and explore your cost data, and save the
                        analyses as reports so that you can share with the various member accounts
                        under your master account. On the Analysis Reports page, you can use some
                        commonly used analysis reports preconfigured by HUAWEI CLOUD. Also you
                        can create budget reports on the Budget Reports page to track your
                        budgeting on a regular basis.
                 ●      Billing Mode: provides you with your RI utilization, RI coverage, net savings,
                        and potential savings on the Reserved Instances page.
                 ●      Cost Tags: helps you identify and manage your HUAWEI CLOUD resources by
                        tag. You can activate the tags to track your HUAWEI CLOUD costs for cost
                        analysis and budget management.

User Guide                                                                                    1 About Cost Center

1.2 Data Scope
                         NOTE

                        The cost and usage data in Cost Center is only for your reference during the cost analysis
                        and budget management.

                 Cost Center prepares your cost and usage data for the last 18 months.

                 ●      If you are an individual HUAWEI CLOUD customer, Cost Center provides you
                        with cost and usage data generated based on your resource usage.
                 ●      If you are an enterprise customer and are using the master account, you can
                        access the following data in Cost Center:
                        –    Your own cost and usage data
                        –    Your member accounts' cost and usage data generated during association
                             with your account for unified accounting management
                 ●      If you are using a member account associated with the master account for
                        unified accounting management, Cost Center provides you only with the cost
                        and usage data generated during the association period. If you are no longer
                        associated with the master account and have become an individual customer,
                        the cost and usage data generated during the association period will no
                        longer be available to you. You will only be able to access the data generated
                        during the disassociation period.
                 ●      If you are using a member account (non-unified accounting management),
                        you can view your cost and usage data like an individual customer.

                 Currently, Cost Center cannot be used to manage the costs of solution partners
                 (including resellers) and reseller customers.

1.3 Cost Type
                 The Cost Center provides you with two types of costs.

                 ●      Original cost: reflects the expenditures after discounts, excluding cash
                        coupons. To view the expenditures after both discounts and cash coupons, see
                        the net original cost.
                 ●      Amortized cost: reflects the amounts prepaid for yearly/monthly services and
                        reserved instances, which are amortized on a daily basis. For example, if you
                        purchased a one-year cloud service at $365 USD, the amortized cost per day is
                        $1 USD. For detailed rules, see Rules for Amortized Costs. Cash coupons are
                        not considered when the cost is amortized. To learn about the amortized cost
                        after cash coupons, see the net amortized cost.

1.4 Data Precision
                 ●      Original costs and billed amounts are calculated to the 8th decimal place.
                 ●      Amortized costs are rounded off and have a slight precision difference.
                        The costs for the following orders need to be amortized:

                        –   Yearly/monthly subscriptions
                        –   Reserved instances
                        –   Monthly-settled CDN services (if you enabled)
                        Data precision for the amortized costs:
                        –   The amortized costs of orders before July 1, 2021 are calculated to the
                            2nd decimal place.
                        –   The amortized costs of orders after July 1, 2021 are rounded off to the
                            8th decimal place.
                            The amounts displayed on the Cost Center pages are rounded off to the
                            2nd decimal place. The amounts included in exported cost details are
                            calculated to the 8th decimal place.

                                            2        Enabling Cost Center

                 You need to enable Cost Center before using it.

Important Notes
                 After Cost Center is enabled, HUAWEI CLOUD will prepare your cost data from the
                 last 18 months. The data is available for viewing in about 24 hours.
                 By default, IAM users do not have the permission required to access Cost Center.
                 See Permissions for details about how to obtain the permissions.
                 Cost Center is enabled by default for the master account and for any member
                 accounts associated for unified accounting management. If a previously associated
                 account is disassociated but still wants to access Cost Center, they need to enable
                 Cost Center.

Procedure
         Step 1 Go to the Billing Center.
         Step 2 Choose Cost Center.
         Step 3 Click Enter Cost Center.
         Step 4 Read and ensure you understand the information in the displayed dialog box,
                select the check box, and click Enable to enable Cost Center. You can also click

4.3 Rules for Recording Amortized Costs
                 This section describes the rules for recording amortized costs and net amortized
                 costs.

Pay-per-Use Resources
                         NOTE

                        For pay-per-use resources settled on a monthly basis (for example, CDN billed by 95th
                        percentile bandwidth), the amortized cost is recorded from when the bills are settled. This
                        explains why there may be a peak in the middle of a month.

                 The amortized costs of pay-per-use resources are calculated based on the resource
                 usage.
                 ●      If the time when a pay-per-use resource started being used (the first time
                        expenditures were incurred) and the transaction time (when the amount due
                        was paid) were in the same billing cycle, the amortized cost of the resource is
                        recorded for the day when it started being used.
                        Example: Suppose you used a pay-per-use resource from June 10, 2021
                        23:00:00 to June 10, 2021 23:59:59, the transaction time was June 11, 2021
                        00:53:30, and the amount due was $2 USD.
                        Cost amortization: As the time when expenditures were incurred (June 10,
                        2021 23:00:00) and the transaction time (June 11, 2021 00:53:30) were in the
                        same billing cycle, the amount due ($2 USD) is recorded as the amortized
                        cost for June 10, 2021.
                 ●      If the time when a pay-per-use resource started being used (the first time
                        expenditures were incurred) and the transaction time (when the amount due
                        was paid) were not in the same billing cycle, the amortized cost of the
                        resource is recorded for the transaction day.
                        Example: Suppose you used a pay-per-use resource from June 30, 2021
                        23:00:00 to June 30, 2021 23:59:59, the transaction time was July 1, 2021
                        00:53:30, and the amount due was $2 USD.
                        Cost amortization: As the time when expenditures were incurred (June 30,
                        2021 23:00:00) and the transaction time (July 1, 2021 00:53:30) were not in
                        the same billing cycle, the amount due ($2 USD) is recorded as the amortized
                        cost for July 1, 2021.

Yearly/Monthly Subscriptions or Reserved Instances
                 As of August 01, 2020 00:00:00 GMT+08:00, the costs of new subscriptions are
                 amortized based on the following rules:
                 ●      Daily amortized cost = Order amount/Number of days in the order effective
                        term (expiration time – effective time)
                 ●      If the resources in an order are not enabled, the costs of such resources are
                        not amortized.
                 ●      If the order effective time and order expiration time are on the same day, the
                        cost of the order is not amortized but is recorded for that day, instead.
                 ●      If a subscription is renewed but the order effective time has elapsed, the
                        historical costs will still be amortized over the time the order was effective.
                 ●      Daily amortized cost for unsubscribed or downgraded orders = Refund
                        amount/Number of days in the order effective term (expiration time –
                        effective time)
                        The costs incurred during the elapsed days are recorded as amortized costs
                        for the day when the orders were unsubscribed from or downgraded. The
                        remaining costs are amortized over the upcoming days.
                        For example, if you subscribe to a 30-day product for $60 USD and request a
                        full-amount refund on the third day of the subscription month, then the cost
                        amortized over the first three days ($-2 USD each day and $-6 USD in total) is
                        recorded as amortized cost for the day when the order was refunded, and $-2
                        USD is recorded as amortized cost for each of the remaining days from the
                        4th day to the 30th day.

Enterprise Projects and Tags for Amortized Costs
                 Yearly/Monthly Subscriptions
                 ●      Enterprise project: By default, the enterprise project selected for the order is
                        used for the amortized costs of your yearly/monthly resources.
                 ●      Tags: Starting from June 1, 2021, the resource tags used when the amortized
                        costs are calculated are applied to the daily amortized costs of your yearly/
                        monthly resources. Tags for costs amortized before June 1, 2021 do not
                        change even if the tags for their resources change.

                 Pay-per-Use Resources
                 The enterprise project and cost tags used when pay-per-use resources are settled
                 are used for your amortized costs.

Example
                 If you placed a yearly/monthly order (valid from December 11, 2020 to January
                 10, 2021) and paid $300 USD, and then unsubscribe from the order on December
                 21, 2020 and pay a handling fee of $5 USD, the daily amortized cost will be $10
                 USD.
                 You will see two amortized cost records for December, 2020.
                 ●      One for the total cost of $200 USD to be amortized over the period from
                        December 11, 2020 to December 31, 2020.
                 ●      The other for the sum of the refund and the handling fee ($-95 USD in total).
                        (On the unsubscription day of December 21, 2020, the refund of $100 USD is
                        recorded. The refund is not recorded as the amortized cost but the handling
                        fee of $5 USD is recorded as the amortized cost.)

5.1 Creating a Budget
                 You can set budget thresholds and configure alerts to track your daily, monthly,
                 and quarterly costs and your resource usage. If your actual costs exceed the
                 configured budget threshold, you will receive a notification.

Important Notes
                 Alerts are not supported for the current month for certain cloud services, such as
                 CDN billed by 95th percentile bandwidth, because their usages for the current
                 month will not be billed until the following month.
                 You can create up to 1,000 budgets.
                 Each recipient can receive a maximum of 100 notifications a day.
                 The budget monitoring data is updated hourly, so your actual costs and usage
                 may have already exceeded the budget when you receive a notification.

                                   one by one. If the budgeted amount is not set for a period, the
                                   amount most recently entered will be applied. For example, if
                                   the budgeted amount of May 2021 is not set, the system will
                                   inherit the budgeted amount from April 2021.

Alerts
                 ●      When the actual cost or usage reaches the configured threshold, the system
                        will notify the recipients by email or SMS.

                        receive a maximum of 100 budget alerts a day. Plan your budget
                        appropriately.
                 ●      Within a budget monitoring period, the alert notification is sent only once
                        even if more than one configured thresholds are reached.
                        Assume that you set the budgeted amount to $100 USD, and alert thresholds
                        to 60%, 70%, and 80%. If the actual cost is $85 USD (85% of the budgeted
                        amount), the system will send only one alert, informing recipients that the
                        current cost exceeds 80% of the budgeted amount.
                 ●      An alert is sent only once for each threshold in a reset period.
                        Assume that you set the reset period to Monthly, budgeted amount to $100
                        USD, and threshold to 80%. If the actual cost of the current month reaches
                        $80 USD (80% of the budgeted amount), the system will report an alert.
                        If the threshold of the current month is changed to 90%, the system will
                        check costs based on the new threshold. If the actual cost of the current
                        month reaches $90 USD (90% of the budgeted amount), the system will send
                        an alert again.
