## Source File
|
||
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/08_Networking/ctp-topic-18-wide-area-networking-in-aws-cloud.md]]
|
||
|
||
## Summary
|
||
- 核心主题:AWS 云环境中的广域网(WAN)架构设计及其演进路径
|
||
- 问题域:大型企业跨国云网络管理、跨区域连接、远程访问优化
|
||
- 方法/机制:Transit Gateway (TGW) 星型拓扑、SD-WAN 叠加网络、Prisma Access SASE 架构
|
||
- 结论/价值:展示从传统静态路由到智能SD-WAN演进的完整路径,为企业云网络架构提供实践参考
|
||
|
||
## Key Claims
|
||
- Transit Gateway 是 AWS 区域级网络中转服务,连接 VPC、本地网络及跨区域 TGW
|
||
|
||
## Key Quotes
|
||
> "将全球划分为三个地理区域(APJ、EMEA、AMS),每个区域设立一个核心 Hub(如 EMEA 的伦敦,AMS 的俄勒冈)。所有 Landing Zones 通过 TGW Peering 接入区域 Hub,形成星型拓扑"
|
||
|
||
> "当前 TGW 间的路由主要基于静态前缀列表(Prefix Lists),缺乏动态路由协议(如 BGP)支持"
|
||
|
||
> "计划引入 Silver Peak 的 SD-WAN 方案作为叠加网络(Overlay),实现动态路径选择和自动化流量调度"
|
||
|
||
> "计划将传统 Pulse VPN 迁移至 Palo Alto 的 Prisma Access(SASE 架构)"
|
||
|
||
## Key Concepts
|
||
- [[Transit Gateway]]:AWS 区域级网络中转服务
|
||
- [[Landing Zone]]:企业标准化的 AWS 多账号环境
|
||
- [[Hub-and-Spoke]]:星型拓扑结构
|
||
- [[SD-WAN]]:软件定义广域网
|
||
- [[Prisma Access]]:Palo Alto 的 SASE 安全访问服务
|
||
- [[Overlay Network]]:叠加网络
|
||
|
||
## Key Entities
|
||
- [[AWS]]:亚马逊云服务平台
|
||
- [[Christian Deckelman]]:Micro Focus IT 网络架构师,演讲人
