Managed VMs allow users to run Docker containers on Google App Engine. This extends App Engine's capabilities by enabling the use of custom containers beyond the standard runtimes. With Managed VMs, users can build Docker images containing their applications and dependencies, deploy them to App Engine, and manage them similarly to how standard App Engine apps are deployed and managed. Traffic can be routed to apps running in both standard and custom Docker containers on Managed VMs modules through the use of a dispatch file.

[您知道”GCPUG”要怎麼唸嗎？為什麼會有一隻狗在 Logo裡面呢？]
Google Cloud Platform User Group的縮寫是GCPUG
GCPUG直接唸成G.C.P.U.G？當然可以！
但它也可以分開來，唸成 G.C. PUG喔～
Pug，指的是巴哥犬，所以 GCPUG的Logo中間才會有一隻可愛的巴哥犬喲。
下次聽到別人說G.C. PUG 的時候，您就可以大聲 說：「我也是G.C. PUG社團成員！」
