Google Cloud Well-Architected Framework skill for the Cost Optimization pillar

面向成本优化支柱的Google Cloud架构完善框架技能

Overview

概述

The Cost Optimization pillar of the Google Cloud Well-Architected Framework provides a structured approach to optimize the costs of your cloud workloads while maximizing business value. Cloud costs differ significantly from on-premises capital expenditure (CapEx) models, requiring a shift to operational expenditure (OpEx) management and a culture of accountability (FinOps).
Google Cloud架构完善框架的成本优化支柱提供了一种结构化方法，可在最大化业务价值的同时优化云工作负载的成本。云成本与本地资本支出（CapEx）模式存在显著差异，这要求转向运营支出（OpEx）管理以及问责文化（FinOps）。

Relevant Google Cloud products

相关Google Cloud产品

The following are examples of Google Cloud products and features that are relevant to cost optimization:
  • Visibility and monitoring:
    • Cloud Billing reports: Native dashboards for visualizing spending and trends.
    • BigQuery billing export: Enables granular, custom analysis of billing data using SQL and BI tools.
    • Looker Studio: Used for creating detailed, shared cost dashboards and reports.
    • Billing alerts and budgets: Automated notifications when spending reaches predefined thresholds.
  • Automation and optimization tools:
    • Recommender / Active Assist: Automatically identifies idle resources, rightsizing opportunities, and unused commitments.
    • Cloud Hub Optimization: Integrates billing and resource utilization data to help developers and application owners quickly identify their most expensive, fluctuating, or underutilized cloud resources.
    • FinOps hub: Presents active savings and optimization opportunities in one dashboard.
    • Billing quotas: Limits on resource consumption to prevent unexpected cost spikes.
  • Efficient infrastructure:
    • Managed services and serverless services: Services like Cloud Run, Cloud Run functions, and GKE Autopilot reduce operational overhead and pay-per-use scaling.
    • Compute Engine: Use of Spot VMs for fault-tolerant workloads and Committed Use Discounts (CUDs) for stable workloads.
    • Cloud Storage Lifecycle Policies: Automatically moves data to lower-cost storage classes (Nearline, Coldline, Archive) based on age or access.
  • Organization and governance:
    • Resource Manager: Logical structure (Organizations, Folders, Projects) for cost attribution.
    • Labels: Metadata tags for categorizing and filtering costs by environment, team, or application.
    • Organization Policy Service: Enforces constraints (e.g., restricted regions or machine types) to control costs.
以下是与成本优化相关的Google Cloud产品和功能示例：
  • 可见性与监控：
    • Cloud Billing reports：用于可视化支出和趋势的原生仪表板。
    • BigQuery billing export：支持使用SQL和BI工具对账单数据进行精细化的自定义分析。
    • Looker Studio：用于创建详细的共享成本仪表板和报告。
    • Billing alerts and budgets：当支出达到预定义阈值时发送自动通知。
  • 自动化与优化工具：
    • Recommender / Active Assist：自动识别闲置资源、规格优化机会和未使用的承诺额度。
    • Cloud Hub Optimization：整合账单和资源利用率数据，帮助开发者和应用所有者快速识别成本最高、波动最大或利用率不足的云资源。
    • FinOps hub：在单一仪表板中展示可立即实现的节省和优化机会。
    • Billing quotas：设置资源消耗限制，防止意外成本激增。
  • 高效基础设施：
    • 托管服务与无服务器服务：Cloud Run、Cloud Run functions和GKE Autopilot等服务可降低运营开销，并支持按使用量付费的弹性扩展。
    • Compute Engine：针对容错工作负载使用Spot VM，针对稳定工作负载使用Committed Use Discounts（CUDs）。
    • Cloud Storage Lifecycle Policies：根据数据时长或访问情况自动将数据迁移至低成本存储类别（Nearline、Coldline、Archive）。
  • 组织与治理：
    • Resource Manager：用于成本归属的逻辑结构（组织、文件夹、项目）。
    • Labels：用于按环境、团队或应用对成本进行分类和过滤的元数据标签。
    • Organization Policy Service：实施约束（如限制区域或机器类型）以控制成本。

Workload assessment questions

工作负载评估问题

Ask appropriate questions to understand the cost-related requirements and constraints of the workload and the user's organization. Choose questions from the following list:
  • How do you incorporate cost considerations into your cloud architecture design process?
  • How do you foster a culture of cost awareness among your development teams?
  • How do you monitor and manage cloud costs across different projects or departments?
  • What strategies do you use to optimize the cost of your compute resources?
  • How do you balance cost optimization with the need for agility and innovation?
  • How do you ensure that you are not over-provisioning cloud resources?
  • How do you use data and analytics to drive cost optimization decisions?
  • How do you optimize costs in different environments (e.g., development, testing, production)?
  • How do you ensure that your cost optimization efforts are sustainable and ongoing?
  • How do you measure the success of your cloud cost optimization initiatives?
提出合适的问题，以了解工作负载和用户组织的成本相关需求与约束。可从以下列表中选择问题：
  • 您如何将成本考量融入云架构设计流程？
  • 您如何在开发团队中培养成本意识文化？
  • 您如何跨不同项目或部门监控和管理云成本？
  • 您采用哪些策略优化计算资源的成本？
  • 您如何平衡成本优化与敏捷性和创新需求？
  • 您如何确保不过度配置云资源？
  • 您如何利用数据和分析驱动成本优化决策？
  • 您如何在不同环境（如开发、测试、生产）中优化成本？
  • 您如何确保成本优化工作可持续且持续进行？
  • 您如何衡量云成本优化举措的成功？

Validation checklist

验证清单

Use the following checklist to evaluate the architecture's alignment with cost-optimization recommendations:
  • Cost Attribution: 100% of resources are labeled with key metadata (e.g., 
    env
    , 
    team
    , 
    app
    ).
  • Granular Visibility: BigQuery billing export is enabled and used for regular cost reviews.
  • Budgets and Alerts: Every project or business unit has defined budgets and active alerts.
  • Rightsizing: Resources are regularly adjusted based on rightsizing suggestions provided by Active Assist Recommender.
  • Commitment Strategy: Spend is reviewed monthly to optimize Committed Use Discount coverage.
  • Idle Resource Management: Unused disks, IP addresses, and idle VMs are identified and removed monthly.
  • Managed Services: Serverless options are preferred for new workloads unless specific technical constraints exist.
  • Storage Tiers: Lifecycle policies are active for all major storage buckets to minimize archival costs.
使用以下清单评估架构与成本优化建议的契合度：
  • 成本归属：100%的资源都标注了关键元数据（如
    env
    、
    team
    、
    app
    ）。
  • 精细化可见性：已启用BigQuery账单导出，并用于定期成本审查。
  • 预算与警报：每个项目或业务单元都已定义预算并启用警报。
  • 规格优化：根据Active Assist Recommender提供的规格优化建议定期调整资源。
  • 承诺额度策略：每月审查支出以优化Committed Use Discount覆盖范围。
  • 闲置资源管理：每月识别并清理未使用的磁盘、IP地址和闲置VM。
  • 托管服务：除非存在特定技术约束，否则新工作负载优先选择无服务器选项。
  • 存储层级：所有主要存储桶都已启用生命周期策略，以最小化归档成本。
