Huawei Cloud Cost Estimation

Huawei Cloud Cost Estimation and Provisioning

Prices come only from the current response: never guess, analogize, or recall them. Provisioning is the only permitted write path; unsubscribe is console guidance only.

Overview

Estimates Huawei Cloud pre-order costs and, when the user wants to buy or create, provisions resources through an allowlisted hcloud command set, then routes unsubscribe requests to console guidance. Use when the user asks about Huawei Cloud / 华为云 / hcloud pricing, budgets, creation or provisioning in Chinese or English: 报价, 询价, 价格估算, 费用预估, 比价, 开通, 创建, price estimate, budget, quote, pricing, provision, create, purchase. Answer: how much a resource will cost, which spec/billing-mode combination fits, whether a resource can be provisioned, and how to unsubscribe — never by guessing prices, inventing parameters, or running non-allowlisted writes.

• Pricing runs a 4-step RFQ flow (Parse → Clarify → Query → Verify & Present) over hcloud BSS read-only APIs in the fixed region cn-north-1.
• Lifecycle Create is limited to the 74 allowlisted operations in references/lifecycle/commands.md and only after --help, fee review, --dryrun, and explicit confirmation.
• Unsubscribe is console guidance only; no unsubscribe CLI/API is ever emitted or executed.

Prerequisites

Prerequisite check: Huawei Cloud CLI (hcloud) >= 7.2.2 and an authenticated profile with BSS read-only + lifecycle dependency IAM permissions (see references/iam-policies.md). hcloud BSS always uses the fixed region --cli-region=cn-north-1; the resource deploy region is carried inside each quote line's region field.

bashCopy code
hcloud version
hcloud configure list
hcloud BSS ListServiceTypes --cli-region=cn-north-1 --cli-output=json --limit=1

If not installed or authenticated, point the user to references/cli-installation-guide.md. Do NOT configure credentials on the user's behalf and do NOT accept AK/SK/token pasted in chat.

Environment dependency (BSS pricing chain): the price-inquiry chain (ListServiceTypes, ListServiceResources, ListResourceSpecs, ListUsageTypes, ListMeasureUnits, ListRateOnPeriodDetail, ListOnDemandResourceRatings) runs against the authenticated account's BSS (Business Support System) APIs. In sandboxed or restricted environments where BSS access is not provisioned (no service metadata, no executor mapping), the pricing chain cannot be verified end-to-end. In that case state clearly that prices cannot be queried in the current environment, then stop — never guess, estimate from memory, or fabricate amounts.

Scope

In scope

Out of scope — route, don't execute

Execution Pace

Complete chains of at most three hcloud commands directly to the next safety gate. For longer chains, run only two or three commands per round, report progress and the next step, then ask whether to continue. A user may request uninterrupted execution, but clarification, unknown-cost approval, --dryrun, and write confirmation remain mandatory.

Workflow

Pricing — 4-Step RFQ

1. Parse cloud_service_type / resource_type / region / resource_spec plus period or usage; route through references/pricing/semantic/catalog.yml.
2. Clarify missing region, quantity, duration/usage, linear size, ambiguous categories, or unresolved variants in one question with two to four candidates. Disclose and apply only safe defaults: OS=linux, empty AZ, and fee_installment_mode=NA.
3. Query using references/pricing/commands.md: ListServiceResources → ListResourceSpecs → on-demand ListUsageTypes(--resource_type_code) → measure resolution → quotation. Ask on multiple matches; a spec match may still fail. Never invent duration or mix capacity and usage slots.
4. Verify and present that line items sum to the total and currency, period, and quantity align. Present [service] [spec] [region] [quantity × period] = amount, total, and “not a final bill.” Show discounts only when returned.

Lifecycle Create — 7 Gates

Read references/lifecycle/concepts.md, then perform every gate in order:

1. Allowlist — Map intent to an operation in references/lifecycle/commands.md; refuse misses.
2. Help — Run hcloud <Service> <Operation> --help for required and conditional fields. Stop on [APIE_ERROR] or missing schema; never guess.
3. Resolve — Run required read-only dependencies such as VPC, subnet, AZ, image, and flavor. Let the user choose among multiple matches.
4. Cost — Use Pricing when possible. Otherwise disclose “price unknown and may incur charges” and obtain separate approval.
5. Dry — Add global --dryrun to the complete command. Fix and rerun failures; never promote a failed dry run.
6. Confirm — Show resource, region, spec, quantity, billing, known or unknown price, and batch order; wait for explicit confirmation.
7. Execute — Remove only --dryrun. Run multiple commands in order, stop on failure, never auto-rollback, and report succeeded, failed, and unexecuted items.

Any parameter, region, quantity, or operation change invalidates the dry run and confirmation and returns to Help.

Unsubscribe Guidance

Never run or generate unsubscribe CLI/API operations, and never use --dryrun as a substitute for console preview.

• Subscription resources: direct the user to Huawei Cloud Console → Cost Center → Orders → Unsubscriptions. Ask them to back up or migrate data and verify the account, resource, related resources, refund, fees, and refund destination before submission.
• Pay-per-use resources: unsubscribe does not apply. Direct the user to the service console to delete the resource after backup; do not delete it for them.

If automation is requested, preserve this boundary and provide the official unsubscribe rules.

Core Commands

All hcloud BSS commands use --cli-region=cn-north-1. Arrays use dot notation (--product_infos.N.*); output with --cli-output=json. Full contracts and exact templates live in references/pricing/commands.md and references/lifecycle/commands.md.

Resolve project scope (IAM read-only)

bashCopy code
hcloud IAM KeystoneListAuthProjects --cli-region={region} --cli-output=json
hcloud IAM KeystoneListProjects --domain_id={domain_id} --cli-region={region} --cli-output=json

Pricing dimensions (BSS read-only)

bashCopy code
hcloud BSS ListServiceTypes --cli-region=cn-north-1 --cli-output=json --limit=10 --offset=0
hcloud BSS ListServiceResources --service_type_code={cloud_service_type} --cli-region=cn-north-1 --cli-output=json --limit=10 --offset=0
hcloud BSS ListResourceSpecs --charge_mode=1 --cloud_service_type={cst} --resource_type={rt} --region_code={region} --filters.1.key=RESOURCE_SPEC --filters.1.value={spec_hint} --limit=100 --cli-region=cn-north-1 --cli-output=json
hcloud BSS ListUsageTypes --resource_type_code={rt} --cli-region=cn-north-1 --cli-output=json --limit=100 --offset=0
hcloud BSS ListMeasureUnits --cli-region=cn-north-1 --cli-output=json

Period quote (BSS/ListRateOnPeriodDetail, read-only POST)

bashCopy code
hcloud BSS ListRateOnPeriodDetail \
  --project_id={project_id} \
  --product_infos.1.id=1 \
  --product_infos.1.cloud_service_type={cst} \
  --product_infos.1.resource_type={rt} \
  --product_infos.1.resource_spec={spec} \
  --product_infos.1.region={deploy_region} \
  --product_infos.1.period_type={0|2|3|4} --product_infos.1.period_num={n} --product_infos.1.subscription_num={qty} \
  --cli-region=cn-north-1 --cli-output=json

Linear products (volume / bandwidth / share_bandwidth) additionally require --product_infos.N.resource_size={size} --product_infos.N.size_measure_id={17|15}.

On-demand quote (BSS/ListOnDemandResourceRatings, read-only POST)

bashCopy code
hcloud BSS ListOnDemandResourceRatings \
  --project_id={project_id} \
  --product_infos.1.id=1 \
  --product_infos.1.cloud_service_type={cst} \
  --product_infos.1.resource_type={rt} \
  --product_infos.1.resource_spec={spec} \
  --product_infos.1.region={deploy_region} \
  --product_infos.1.usage_factor={factor} --product_infos.1.usage_value={value} --product_infos.1.usage_measure_id={mid} \
  --product_infos.1.subscription_num={qty} \
  --cli-region=cn-north-1 --cli-output=json

Lifecycle create (allowlisted write path)

The 74 allowlisted operations (e.g. ECS/CreateServers, DDS/CreateInstance, RDS/CreateInstance) are enumerated in references/lifecycle/commands.md. Parameters always come from the current --help, never from memory. Minimal executable example (VPC is allowlisted, VPC/CreateVpc is a readily dry-runnable create):

bashCopy code
hcloud VPC CreateVpc --help
hcloud VPC CreateVpc --vpc.name={name} --vpc.cidr=172.16.0.0/16 --cli-region={region} --dryrun

Every other allowlisted operation follows the same shape: run --help first, then build the full command from the help output, add --dryrun, and only remove --dryrun after the dry-run gate and explicit confirmation. Pass the --dryrun gate and explicit confirmation before executing without --dryrun; one failure stops the batch, no auto-rollback.

Lifecycle dependency lookups (read-only)

Run only the dependencies the help output marks required (references/lifecycle/commands.md):

bashCopy code
hcloud EPS ListEnterpriseProject --cli-region=cn-north-4 --cli-output=json
hcloud VPC ListVpcs --cli-region={region} --cli-output=json
hcloud VPC ListSubnets --cli-region={region} --cli-output=json
hcloud ECS NovaListAvailabilityZones --cli-region={region} --cli-output=json
hcloud IMS ListImages --cli-region={region} --cli-output=json
hcloud EVS CinderListVolumeTypes --cli-region={region} --cli-output=json
hcloud ECS NovaListKeypairs --cli-region={region} --cli-output=json
hcloud ECS NovaListFlavors --cli-region={region} --cli-output=json

EPS region note: EPS does not support cn-north-1. Query enterprise projects with --cli-region=cn-north-4 (or another EPS-enabled region such as ru-moscow-1 / my-kualalumpur-1); the returned enterprise_project_id is region-independent for lifecycle create parameters. The BSS fixed region cn-north-1 applies to price inquiry only, never to EPS.

Parameter Confirmation

Missing region, quantity, duration/usage, or linear size is clarified in one question with two to four candidates before any command runs.

Unsubscribe Console Path

Never run or generate unsubscribe CLI/API operations; --dryrun previews request construction only and never replaces the console. Subscription resources go through Console → Cost Center → Orders → Unsubscriptions after data backup and account/resource/refund verification; pay-per-use resources are deleted by the user in the service console after backup.

Critical Rules

1. Prices come from the current response; parameters come from current help.
2. No real create call without a successful --dryrun and explicit confirmation.
3. Never automate or emit unsubscribe operations.
4. Refuse AK, SK, and tokens in chat; point to references/cli-installation-guide.md for self-configuration.
5. Every BSS call uses --cli-region=cn-north-1; product_infos.N.region remains the deployment region.
6. Route out-of-scope work to Cost Center, the appropriate console, or read-only billing.

Use bullets or numbered items, not GFM tables, in user-facing responses. For command-level traps, read references/pricing/commands.md.

KooCLI Command Format Standard

Every command follows the generic KooCLI shape: hcloud <Service> <Operation> --cli-region=<region> [--key=value ...].

Placeholder tokens above (e.g. <Service>) are illustrative only — never run them literally.

Reference Documents

For 403 or permission failures, read references/iam-policies.md. If hcloud is unavailable, relay references/cli-installation-guide.md; never install it for the user.
