## Source File
|
||
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/01_AWS-Landing-Zone/ctp-topic-35-aws-landing-zone-design-refresher-saas-labs.md]]
|
||
|
||
## Summary(用中文描述)
|
||
- 核心主题:AWS Landing Zone 设计复习,重点对比 SaaS(生产)与 Labs(开发)两种 Landing Zone 环境的架构差异与近期变更
|
||
- 问题域:企业多账户 AWS 环境下的账户结构设计、共享服务架构、网络分段策略、以及 SaaS 与 Labs 的职责划分
|
||
- 方法/机制:基于 Gruntwork Terraform 模板构建 Landing Zone IaC;通过 CCOE CloudTrail 替代 Gruntworks CloudTrail 实现统一审计;网络账户 Checkpoint 重新路由入站流量;网络分段阻断 SaaS 工作负载的直接连通性
|
||
- 结论/价值:明确 SaaS = 生产、Labs = 开发的核心定位;PoC Landing Zone 将并入 Labs 以最大化资源共享;Cloud Technology Design Forum 推动 Micro Focus 云交付标准化
|
||
|
||
## Key Claims(用中文描述)
|
||
- Gruntwork 框架的 Landing Zone 通过 Terraform 模板以 IaC 方式构建
|
||
- SaaS Landing Zone 为每个产品区域提供客户专属的产品账户,通过共享服务账户实现安全、日志和网络互联
|
||
- Gruntwork 账户跨所有账户管理 AMI、日志和安全策略
|
||
- 网络分段策略将阻断对 SaaS 工作负载的直接连通性
|
||
- CCOE CloudTrail 取代 Gruntworks CloudTrail 实现统一云审计
|
||
- 入站流量拟通过 Network 账户的 Checkpoint 重新路由
|
||
- 原生 AWS Backup 有望成为强制要求
|
||
- 新账户可能取消 Management VPC
|
||
- SaaS 用于生产环境,Labs 用于开发环境(PoC Landing Zone 将并入 Labs)
|
||
|
||
## Key Quotes
|
||
> "Our AWS landing zones, they're built infrastructure as code as you'd expect on terraform templates using the grunt work framework." — Landing Zone 的 IaC 实现方式
|
||
|
||
> "Basically, the only answer is that SAS is production, Labs is development." — SaaS 与 Labs 的本质区别
|
||
|
||
## Key Concepts
|
||
- [[Landing-Zone-Architecture]]:AWS 多账户架构的基础框架,通过账户隔离实现安全、合规和可管理性
|
||
- [[Gruntwork]]:提供生产级 Terraform 模块的基础设施库,Micro Focus 基于此构建 Landing Zone
|
||
- [[Shared-Services-Account]]:托管共享服务(Artifactory、Cyber Eupriva、ArcSight、监控等)的集中账户
|
||
- [[Core-Accounts]]:包含 Active Directory、DNS 和 Network 账户,支持 IT 服务和 Micro Focus 基础设施
|
||
- [[Product-Accounts]]:托管各产品线的 IT 产品、项目、应用程序及相关 AWS 资源,由各项目团队管理
|
||
- [[Gruntwork-Accounts]]:跨所有账户管理 AMI、日志和安全策略的集中账户
|
||
- [[Network-Segmentation]]:通过 Checkpoint 防火墙和网络分段策略阻断对 SaaS 工作负载的直接连通性
|
||
- [[CloudTrail]]:AWS CloudTrail 日志服务,CCOE CloudTrail 替代原有 Gruntworks CloudTrail 实现统一审计
|
||
|
||
## Key Entities
|
||
- [[Cloud-Technology-Design-Forum]]:Micro Focus 云技术设计论坛,致力于标准化和集中化云交付产品(包括 Landing Zone 设计)
|
||
- [[Checkpoint]]:Network 账户中的防火墙设备,用于重新路由入站流量

|
||
## Contradictions
|
||
- 与 [[ctp-topic-1-gruntwork-landing-zone-architecture]] 视角互补:
|
||
- 冲突点:Landing Zone 中产品定义粒度
|
||
- 当前观点(CTP Topic 35):Landing Zone 产品定义由架构团队统一规划,强调 Cloud Technology Design Forum 推动标准化
|
||
- 对方观点(CTP Topic 1):Landing Zone 由产品团队自行定义具体服务(ECS/RDS 等),产品团队有较大自主权
|
||
- 状态:视角互补而非直接矛盾——CTP Topic 35 强调集中治理与标准化,CTP Topic 1 强调灵活性与产品团队自主性;可能反映组织不同发展阶段或不同业务单元的差异
