下記のように、VPCの設計指針の一つを示し、

SUZ-LAB最前線(VPCのサブネット/ ルーティング/セキュリティ)

サブネットのアドレス体系も定義したので、

VPCのSubnetのCIDRの設計方針(一例として)

最後に、これらをCloud Formation化します。

SUZ-LAB Formation VPC Basic 0.0.1
(全ソースは本記事の最後に記載しています)

それでは、早速、このテンプレートでVPCを構築してみます。

まずは適当なStack NameをつけてProvide a Template URLを選択して、上記のテンプレート(JSON)のURLを入力します。

次にパラメータとして、VPCに設定するCIDRの最初の2オクテットを入力します。

するとCIDRが”X.X.0.0/16″のVPCが構築され始めます。

CloudFormationが終了すると下記のようになります。

実際にVPCを確認すると、次のように問題なく構築されていることがわかります。

ただし、このままだと、NATインスタンスが無いので、Protectedなサブネットから、 外部に通信することができません。(つまり、まだProtectedじゃありません)

ということで、次回はNATインスタンスも組み込んで、ちゃんとProtectedサブネットが 機能するようにします。

最後にCloudFormationのテンプレートを載せておきます。
