概覽公共雲服務

Elastic Compute Cloud (EC2) ->
-> 有擴展問題 -> LB -> Cloud Watch -> Auto Scaling -> 太麻煩
-> Elastic Beanstalk (PAAS) -> 其實不用伺服器 -> Lambda (FAAS aka ServerLess)
OutPosts: 可以跑 AWS 在自己基礎建設
SNOW: 自架
docker: 可以跑不同公雲環境
需要更多可以擴展 -> EKS -> 可以自動擴展？-> FARGATE
既然有 Container，使用App Runner最簡單
儲存？ s3: 可以存任何格式 -> 是否有成本低、高延遲的？ -> Glacier ，速度要快？ Block Storage，要更多權限、可控 > Elastic File System
Database? Simple DB(NoSQL) > Dynamo DB ：便宜、可以水平擴展、快，不可Join，有限查詢，-> Document DB > SQL solution> > RDS ，比MSQL 快？ Aurora
高度連結資料e.g. social graph > Neptune -> 要快速？ Elastic Cache -> 時序性資料？ Timestream ，不可變的加密交易 Quantum Ledger
Fulltext search engine: Elastic Search>
管理帳單：Budgets
分析？Redshift >
科學計算？ SageMaker
圖片辨識？ Rekognition
對話？Alex
學習機器學習？ Deep Racer
權限管理？ IAM
管理登入？ Cognito
