AWS構成図をAIに書かせてみた(PlantUML)

ChatGPTでAWSの構成図を作成するよう頼んでみた。

依頼文はまずこちら。 日本語にも対応すると聞くが、この手のものは拙くとも英語で聞いておくほうがよいと思うので、英語で書いた。日本語で書いてうまくいかなかったら、英語でないのがダメなのか、内容がダメなのか、どっちなのかわからなくなるので切り分けが面倒くさい。

Create an AWS diagram of `VPC network` using `Plantuml` with the following content.
- region is ap-northeast 1
- 3 az
- use s3 vpc endpoint
- using igw

そして生成されたのがこちら。

残念ながらたたき台にもならなかった。PlantUMLでAWS構成図を書くのはマイナーすぎたのかもしれない。

しかし、うまくいくときはかなり素晴らしいたたき台を作ってくれるのがChatGPTだ。懲りずにどんどん試していこうと思う。
