ansibleを使って、iperfでalway free間のネットワークスループットを計測する
Oracle Cloud always free Advent Calendar 2019の9日目です。
本日は、iperfでalway free間のネットワークスループットを計測してみます。
2台でiperfのインストール、firewalldのポート開放などがあるので、ansibleでやってみます。
〇セキュリティリストの確認
oracle cloudコンソールから
ネットワーキング-仮想クラウド・ネットワーク-VirtualCloudNetwork-XXXXXXXを選択
パブリック・パブリックサブネットをクリック
Default Security List for VirtualCloudNetwork-XXXXXXXXXをクリック
イングレス・ルールに以下があることを確認

によるとVM.Standard.E2.1.Microのネットワーク帯域幅は480 Mbpsなので、そのままの結果になったと思います。
