クラウド開発環境「PaizaCloud」の動作確認メモ

エスパ水澤 2020/12/01に更新

PaizaCloudは、ブラウザを開くだけでエディタ、Webサーバ、DB等の開発環境が整うクラウド開発環境。Ruby on Rails, Node.js, Django, MySQL, WordPress, Java(Tomcat), PHP(LAMP), Laravel, Goなど、主要開発環境に対応している。

https://paiza.cloud/ja/

オンラインのコーディングテストを受けることで、書類選考なしに面接・会社見学可能な求人企業が見つかるスキルアップ/転職サービスを提供しているpaizaを運営しているpaiza株式会社が運営している。

PaizaCloudの主な特徴

ブラウザを開くだけ、3秒で環境構築が完了

クラウド上に用意されたエディタ、Webサーバ、DBサーバを利用し、ブラウザを開くだけですぐに開発を進めることが可能。

OSの種類を問わない

ブラウザを開くだけなので、WindowsやMacなど、OSの種類関係なく、誰もが同じ開発環境をすばやく用意できる。

ベーシックな環境は設定済み

ベーシックな開発環境は設定済み。Linuxのシェルを使えるため、自由に開発環境を構築することも可能。

サービスの公開、運用も可能

PaizaCloudで開発したWebサービスは、ベーシックプランに移行すれば一般的なホスティングサービスと同様にそのまま公開、運用できる。

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

76 loaded units listed. Pass --all to see loaded but inactive units, too.
77. To show all installed unit files use 'systemctl list-unit-files'.
