SLIDE 13
早期只⽀攰援 VirtualBox
SLIDE 14
後來⽀攰援 KVM、 VMware 等等⽅斺案
SLIDE 15
包括了今天要提到的 Docker
SLIDE 16
好處
SLIDE 17
可重複測試
SLIDE 18
每次環境相同
SLIDE 19
設定簡單
SLIDE 20
Docker
SLIDE 21
SLIDE 22
Linux 上輕量級的 容器管理⼯左具

Microservices
SLIDE 25
優點
SLIDE 26
啟動速度快
SLIDE 27
節省資源
SLIDE 28
缺點
SLIDE 29
⺫⽬盯前只有 Linux 平台
SLIDE 30
無法指定容器的 IP 位置
