初识 AWS —— 适于初学者之导引
Chandan Mahe · 2026-05-24 · via DEV Community

若尔始尔之云途或运维之道,则一名称号,尔所闻者遍矣。亚马逊云服务(Amazon Web Services).

初闻之亚马逊云服务(Amazon Web Services)吾方在焉。惑矣.

人言其事EC2,VPC,IAM,区域,可用区,负载均衡器……诚然,初时之感,实有不堪重负之虞.

然一旦循序渐进,渐明其理由浅入深,事遂易之.

故于此文,吾将竭力以最简之语,释AWS之奥.

无繁复之定义。

此乃初学易明之导引也.

然则,AWS者,何实也?

AWS者,Amazon Web Services(亚马逊网络服务)之谓也.

此乃亚马逊所创之云平台,使汝能自互联网直用服务器、存储、数据库、网络及诸般他务.

简言之:

不购实体之机柜、服务器而置于案头,AWS可任君需时租之。

数刻间可启服务器,随时可止。

此乃云计之能也。

诸公司何以用AWS?

试思Netflix、Spotify、Airbnb或巨擘新创之公司。

日日亿万之众,用其应用.

手治物理之服务器,以应如此巨流,实难且费.

AWS解此困.

用AWS,诸公司可:

  • 易展其应用
  • 储巨量之数据
  • 布其应用于寰宇
  • 自动化其基构
  • 增其安
  • 减其器之费

至妙者何:
惟所用者而偿之

实例

设欲设网之居

旧法,当备:

  • 器之在堂者
  • 络之设
  • 电之用
  • 致凉之具
  • 維護

然則於 AWS:
數點之間,即可啟動虛擬之伺服器。

此虛擬伺服器謂之 EC2 实例。

汝可部署汝之應用於此,並自任何處而達之。

初學者所當知之 AWS 重要服務

EC2

雲中虛擬之伺服器。

S3

昔用以储诸文件、图像、视频、备份等__

IAM

用以安全管理用户与权限__

RDS

管理数据库之服务__

VPC

助尔于AWS内自建私网__

若此等名目于尔听来生疏,勿忧也。
吾等当于后文逐篇习之。

吾为何以为 AWS 值得研习?

吾个人所好于 AWS 者在于,其授人以实务,得窥世之实构。

汝实可部署应,设网,调安,自化部署,且构类乎生产之境。

是故 AWS 之可贵,在于:

  • 云工师
  • 运维工师
  • 后端匠师
  • 系统司理

终思

尔若始涉云途,勿求毕学于一朝

当循本源

明:

  • 云数之理何在
  • 何故 AWS 存在哉
  • 何谓基础服务之运作

基固则高深之理自易。

后文将释之:
云者何?其运作若何?“何谓?”

乐学无疆。
