paiza.IO と wandbox の環境を比較してみた

最近、開発環境をローカルに構築していないマシンで Qiita 記事を書くことも多く、その際の動作確認は大きく分けて

- paiza.IO
- wandbox

を使うようになりました。
これらの実行環境がどうなっているんだろう？と思ったので、ある程度のコマンドの結果を出してみたので、自分用メモとして残しておきます。

# コマンド

```
pwd
uname -a 
cat /proc/version
cat /proc/cpuinfo
uptime
ps aux
df
free
```

## それぞれの結果

paiza.IO は aws 上で動いている。

## Conclusion

普段の開発は AWS が多いので、そういう意味では paiza.IO の方がいいのか？と思ったり思わなかったり。
ただ AWS でも、メタデータは取れなかったので、インスタンスタイプなどは想像するしかなさそうでした。
