## Definition
|
||||
AWS Landing Zone 是 AWS 推荐的企业级云基础架构框架,通过多账号策略、安全基线、网络架构等组件提供安全、可扩展的云环境起点。
|
||||
|
||||
## Key Components
|
||||
- **多账号策略**:通过 AWS Organizations 管理多个账户
|
||||
- **安全基线**:安全组、SCP、密码策略等
|
||||
- **网络架构**:VPC、Transit Gateway、VPN/Direct Connect
|
||||
- **身份管理**:IAM 角色、SSO、AD 集成

## Definition
|
||||
Break-Glass Access(紧急访问)是指在紧急情况下绕过正常安全控制流程,获得系统访问权限的机制。通常作为备份方案,仅在无法通过正常渠道访问时使用。
|
||||
|
||||
## Application
|
||||
在 AWS Landing Zone 安全策略中,长期目标是基础设施即代码(IaC)以减少控制台访问和 break-glass access 需求,紧急访问仅作为极端情况的最后手段。
|
||||
|
||||
## Best Practices
|
||||
- 严格限制使用频率
|
||||
- 完整记录访问日志
|
||||
- 事后审查和报告
|
||||
- 逐步减少对它的依赖

## Summary
|
||||
变更管理是 ITSM 的核心流程之一,用于控制和管理 IT 环境的任何变更,降低变更风险并确保服务质量。
|
||||
|
||||
## Definition
|
||||
在云转型项目中,变更管理涉及对生产环境或基础设施的任何修改的控制、审批和跟踪。
|
||||
|
||||
## Change Types
|
||||
|
||||
### 标准变更 (Standard Change)
|
||||
- 预批准变更,无需变更咨询委员会(CAB)批准
|
||||
- 风险低、影响小、高度可预测
|
||||
- 应尽可能实现完全自动化(IaC + CI/CD Pipeline)
|
||||
- 示例:标签更新、配置参数调整等
|
||||
|
||||
### 正常变更 (Normal Change)
|
||||
- 包含一定风险或影响的变更
|
||||
- 需要 CAB 批准,并可能需要跨团队协调
|
||||
- 有预定义的变更窗口
|
||||
- 示例:新服务部署、架构变更等
|
||||
|
||||
### 紧急变更 (Emergency Change)
|
||||
- 为了缓解事故并尽快恢复服务到期望状态而需要立即执行的变更
|
||||
- 事后通过 CAPA/Post-mortem 修复根因
|
||||
- 示例:紧急安全补丁、热故障修复等

## Description
|
||||
|
||||
Cyber Suite(网络安全套件标准)是由 PSAC(Product Security Approval Committee)团队发布的网络安全标准文档,定义了 CTP 项目中产品必须遵循的加密算法和安全配置。
|
||||
|
||||
## Updated Standards
|
||||
|
||||
更新后的 Cyber Suite 标准包括:
|
||||
|
||||
### Considered Standard(标准套件)
|
||||
- 符合 FIPS 标准
|
||||
- Java、Golang、Node.js、OpenCel for CNC++ 兼容
|
||||
|
||||
### Optional(可选套件)
|
||||
- 为向后兼容提供
|
||||
- 但包含 CBC(Cipher Block Chaining)模式,被认为安全性较弱
|
||||
|
||||
### Cipher Selection
|
||||
|
||||
产品可从不同类别选择加密套件:
|
||||
- 密钥交换(Key Exchange)
|
||||
- 认证(Authentication)
|
||||
- 加密(Encryption)
|
||||
- 哈希(Hash)
|
||||
|
||||
### Review Requirement
|
||||
|
||||
使用非标准和可选套件之外加密算法的产品需经过 PSAC 团队审查。

## Definition
|
||||
Error Budget(错误预算)是系统在不影响客户的前提下可以不可靠的最大时间量。它弥合了开发与运维之间的鸿沟,将失败正常化为开发过程的一部分。
|
||||
|
||||
## Calculation
|
||||
```
|
||||
Error Budget = 1 - 可用性 SLO
|
||||
```
|
||||
|
||||
例如:
|
||||
- 99.9% SLO → 0.1% Error Budget
|
||||
- 99.99% SLO → 0.01% Error Budget
|
||||
|
||||
完美可用性是 100%,Error Budget 落在 SLO 和 100% 之间。
|
||||
|
||||
## Usage
|
||||
- **在预算内**:开发者可以承担更多风险,快速交付功能
|
||||
- **超出预算**:开发者必须做出更保守的选择,优先保证稳定性
|
||||
|
||||
## Measurement
|
||||
- [[SLI(服务等级指标)]]:可靠性的可量化度量指标
|
||||
- [[SLO(服务等级目标)]]:服务应该达到的性能/可靠性目标
|
||||
- [[SLA(服务等级协议)]]:客户级别的正式协议
|
||||
|
||||
## Importance
|
||||
1. **监控能力**:快速显示 Error Budget 是否未充分利用或已超出
|
||||
2. **小幅度变更**:小迭代变更和充分测试的部署是管理 Error Budget 的关键
|
||||
3. **混沌工程**:通过故意引发故障测试系统韧性,确保满足 NFR
|
||||
|
||||

## Definition
|
||||
GitHub-Enterprise to GitLab Migration(GitHub Enterprise 到 GitLab 迁移)是 OpenText 将源代码仓库从 GitHub Enterprise 迁移到 GitLab 的企业级迁移项目。
|
||||
|
||||
## Migration Approaches
|
||||
- **Mirroring**:将 GitHub 仓库同步到 GitLab,保持持续更新
|
||||
- **Shift and Lift**:将代码复制到 GitLab 并同时转换 CI/CD 管道
|
||||
|
||||
## Migration Tracking
|
||||
- 通过 PHT(Product Hub platform)跟踪进度
|
||||
- 定期向开发经理和构建倡导者更新
|
||||
- 规划指南:清点 GitHub 资产、识别管道、了解网络连接
|
||||
|
||||
## Key Milestones
|
||||
1. 安装 GitLab 插件
|
||||
2. 早期访问 GitLab
|
||||
3. 映射仓库到 PHT
|
||||
4. 设置服务账户
|
||||
5. 更新管道
|
||||
|
||||
## Network Connectivity
|
||||
- GitLab proxy 位于 Brook Park,可通过 SD1 访问
|
||||
- 商业实例连接 GitLab 可能需要 GIS 团队批准例外

## Definition
|
||||
NFR(Non-Functional Requirements,非功能需求)是评判系统运行状况的标准,决定可用性、性能、安全性、可扩展性等属性。
|
||||
|
||||
## Key Aspects
|
||||
- **可用性(Availability)**:系统正常运行时间比例(如 99.9%、99.99%)
|
||||
- **性能(Performance)**:响应时间、吞吐量等
|
||||
- **安全性(Security)**:数据加密、访问控制等
|
||||
- **可扩展性(Scalability)**:水平/垂直扩展能力
|
||||
|
||||
## Cloud Context
|
||||
在云端,NFR 应更规范化,利用云原生服务:
|
||||
- AWS Backup 定义备份策略和测试频率
|
||||
- DR 规划包含季度测试和 IaC 基础设施
|
||||
- NFR Epic 集成到 Sprint backlog
|
||||
|
||||
## Relationship with SRE
|
||||
- [[SRE]] 通过 [[Error Budget(错误预算)]] 和 [[SLO(服务等级目标)]] 实现 NFR
|
||||
- [[混沌工程]] 验证 NFR 是否满足

1. **Metrics(指标)**:数值型数据,如 CPU 使用率、请求延迟
|
||||
2. **Logs(日志)**:事件记录,详细描述系统活动

## Aliases
|

- Overlay Network
|
||||
- 叠加网络
|
||||
|
||||
## Description
|
||||
叠加网络(Overlay Network)是在现有物理网络(Underlay)之上构建的逻辑网络,用于实现复杂的路由和隧道功能。常见的 Overlay 协议包括 VXLAN、GRE、IPsec 等。在 SD-WAN 架构中,Overlay 网络负责路径选择和流量调度,与底层的物理网络解耦。
|
||||
|
||||
## Use Cases
|
||||
- SD-WAN 叠加网络
|
||||
- 容器网络(如 Kubernetes CNI)
|
||||
- VPN 隧道
|
||||
- 云间互联

## Definition
|
||||
恢复保障(Recovery Assurance)是一种从设计层面确保系统具备恢复能力的架构理念,与传统的灾难恢复(DR)不同,它强调主动式而非被动式响应。
|
||||
|
||||
## Key Differences from DR
|
||||
- **DR(灾难恢复)**:被动响应,事件发生后尝试恢复
|
||||
- **Recovery Assurance**:主动设计,在设计阶段就考虑恢复能力
|
||||
|
||||
## Core Principles
|
||||
1. **Design for Failure**:假设组件会故障,设计容错机制
|
||||
2. **Observability**:持续监控系统健康状态
|
||||
3. **Automation**:自动检测和恢复能力
|
||||
4. **Test-Driven**:通过测试验证恢复能力
|
||||
|
||||

## Description
|
||||
软件定义广域网(SD-WAN)是一种通过软件控制层对物理网络进行抽象的技术,实现动态路径选择和负载均衡。在企业云架构中,SD-WAN 通常作为 Overlay Network(叠加网络)部署在 AWS 等公有云上,解决静态路由的局限性。
|
||||
|
||||
## Use Cases
|
||||
- 多分支机构网络互联
|
||||
- 动态路径选择和流量调度
|

## Definition
|
||||
SLA(Service Level Agreement,服务等级协议)是客户级别的正式协议,定义了服务提供者对客户的承诺。
|
||||
|
||||
## Key Characteristics
|
||||
- **具有法律约束力**:违反可能涉及经济赔偿
|
||||
- **比 SLO 更宽松**:SLO 是团队内部目标,SLA 是对客户的承诺
|
||||
- **基于 SLO**:SLA 通常基于内部 SLO 制定
|
||||
|
||||
## Relationship
|
||||
- [[SLA(服务等级协议)]] ← based_on ← [[SLO(服务等级目标)]]
|
||||
- [[SLO(服务等级目标)]] ← measures ← [[SLI(服务等级指标)]]
|
||||
|
||||
## Example
|
||||
- SLO: 99.9% 可用性(内部目标)
|
||||
- SLA: 99.5% 可用性(对客户承诺,更宽松)

## Definition
|
||||
SLI(Service Level Indicator,服务等级指标)是可靠性的可量化度量指标,用于衡量系统健康状态。
|
||||
|
||||
## Common SLIs
|
||||
- **可用性**:成功请求占总请求的比例
|
||||
- **延迟**:请求响应时间(如 P99 延迟)
|
||||
- **错误率**:失败请求占总请求的比例
|
||||
- **吞吐量**:每秒处理的请求数(QPS)
|
||||
|
||||
## Usage
|
||||
SLI 被 [[SLO(服务等级目标)]] 引用,用于测量服务是否达到预期可靠性水平。
|
||||
|
||||
## Relationship
|
||||
- [[SLI(服务等级指标)]] ← measures ← [[SLO(服务等级目标)]]
|
||||
- [[SLO(服务等级目标)]] ← derives ← [[Error Budget(错误预算)]]
|
||||
- [[SLA(服务等级协议)]] ← based_on ← [[SLO(服务等级目标)]]

## Definition
|
||||
SLO(Service Level Objective,服务等级目标)定义了服务应该达到的性能/可靠性目标,是团队努力实现的具体指标。
|
||||
|
||||
## Common SLOs
|
||||
- **可用性目标**:99.9%(三个九)、99.99%(四个九)
|
||||
- **延迟目标**:P99 响应时间 < 200ms
|
||||
- **错误目标**:错误率 < 0.1%
|
||||
|
||||
## Relationship with Error Budget
|
||||
SLO 与 Error Budget 直接关联:
|
||||
```
|
||||
Error Budget = 1 - 可用性 SLO
|
||||
```
|
||||
|
||||
例如:99.9% SLO → 0.1% Error Budget
|
||||
|
||||
## Hierarchy
|
||||
- [[SLI(服务等级指标)]] → measures → SLO
|
||||
- SLO → derives → [[Error Budget(错误预算)]]
|
||||
- SLO → satisfies → [[SLA(服务等级协议)]]

# SMACs
|
||||
|
||||
SMACs(Service Management Access)是一个需求提交的标准化入口,用于启动计时器和确保需求被追踪。
|
||||
|
||||
## 核心特征
|
||||
|
||||
- 标准化提交:所有新需求必须通过 SMACs 提交
|
||||
- 计时启动:提交后开始计时
|
||||
- 追踪保证:确保需求被完整记录
|
||||
|
||||
## 使用方式
|
||||
|
||||
- 提交新需求
|
||||
- 追踪需求状态
|
||||
- 关联评审会议
|
||||
|
||||
## 替代方案
|
||||
|
||||
- 邮件或聊天可作为初始联系方式
|
||||
- SMACs 是最可靠的追踪方式

|
||||
|
||||
## Characteristics
|
||||
- 各团队自行定义在 GitHub 中拥有的资产
|
||||
- 各团队规划如何移动代码和转换 CI/CD 管道

## OpenText Tagging Standard V2
|
||||
OpenText Tagging Standard V2 是标签方法论的具体实现,由 Phenops 团队于 2023 年发起,扩展了以下应用范围:
|
||||
- 云账号
|
||||
- 云资源(计算、存储、网络)
|
||||
- Kubernetes 对象(namespace、pod、deployment、service、configmap)
|
||||
- 容器镜像
|
||||
|
||||
### 标签规范特点
|
||||
- 使用小写下划线语法(如 `ot_business_unit`)
|
||||
- 前缀标签确保语义明确:
|
||||
- OT_ 用于云标签
|
||||
- app.opentext.com 用于 Kubernetes 标签
|
||||
- com.opentext.image 用于容器镜像标签

|
||||
|
||||
## Position in Architecture Hierarchy
|
||||
- **企业架构(Enterprise Architecture, EA)**:高层,负责将业务目标转化为技术原则和标准
|
||||
- **方案架构(Solution Architecture, SA)**:中间层,负责特定项目或服务的优化实施
|
||||
- **技术架构(Technical Architecture, TA)**:底层,负责具体基础设施的设计和实施治理
|
||||
|
||||
## Responsibilities
|
||||
- 维护AWS Enterprise Landing Zones(企业落地分区)
|
||||
- 制定技术路线图(12-24个月前瞻性规划)
|
||||
- 推行"云优先(Cloud-first)"策略
|
||||
- 技术领域(Technical Domains)的生命周期管理

## Definition
|
||||
将公司技术栈划分为特定的领域(如身份认证、网络、Microsoft堆栈等),每个领域由专人负责其生命周期与路线图。
|
||||
|
||||
## Purpose
|
||||
- 通过首席架构师负责制,实现12-24个月前瞻性路线图规划
|
||||
- 帮助业务部门规避潜在风险、优化预算并提升交付速度
|
||||
- 从"救火式"响应转变为预测性规划
|
||||
|
||||
## Examples
|
||||
- 身份认证领域(Identity & Access)
|
||||
- 网络领域(Networking)
|
||||
- Microsoft堆栈领域

## Definition
|
||||
WSJF(加权最短作业优先)是一种用于序列 CTP(云转型计划)工作的优先级排序方法,基于成本效益最大化原则。
|
||||
|
||||
## Formula
|
||||
```
|
||||
WSJF = (业务价值 + 时间关键性 + 风险与机会) / 作业规模
|
||||
```
|
||||
|
||||
## Components
|
||||
- **业务价值 (Business Value)**:收入增加、成本降低、风险改善
|
||||
- **时间关键性 (Time Criticality)**:工作的时间敏感性
|
||||
- **风险与机会 (Risk & Opportunity)**:潜在风险和机会评估
|
||||
- **作业规模 (Size of Job)**:完成工作所需的 effort
|
||||
|
||||
## Application
|
||||
用于在多个需求之间进行优先级排序,以实现:
|
||||
- 最小 effort 实现最大 value
|
||||
- 早期价值交付回业务
|
||||
- 最大化经济利益
|
||||

||||

## Definition
|
||||
零信任访问(Zero Trust Access)是一种安全框架,遵循"永不信任、始终验证"原则,每次访问请求都需经过身份验证和授权,无论请求来自网络内部还是外部。
|
||||
|
||||
## Application
|
||||
在 AWS Landing Zone 中,通过 SSM 实现零信任访问:用户需扮演 IAM 角色获得目标 EC2 实例的 SSM agent 访问权限,依赖现有访问控制并启用双因素认证。
