VPC Lambdaで複数のサブネットを指定した場合にどちらのサブネットで起動するか確認してみた
このLambda関数はどっちのサブネットで起動するんだ
こんにちは、のんピ(@non____97)です。
皆さんはVPC Lambdaで複数のサブネットを指定した場合に、どちらのサブネットで起動するか気になったことはありますか? 私はあります。
単純なラウンドロビンなのか、それともランダムなのか、何か優先度があるのか地味に気になりますよね? きっと皆さんも興味津々だと思います。
今回、どちらのサブネットで起動するのかを検証してみました。
いきなりまとめ
- どちらのサブネットで起動するかは恐らくランダム
検証パターン
検証はLambda関数を300回非同期で並列実行して確認をします。
VPC LambdaはHyperplane ENIを介して自分が用意したVPCにアクセスします。複数のLambda関数がある場合もHyperplane ENIを共有し、Hyperplane ENIからVPC内のENIにNATされます。
以下の構成でどちらのサブネットのENI多く使用するかを確認します。
どのLambda関数がどちらのサブネットで起動したかはhttps://checkip.amazonaws.comにアクセスして、どちらのサブネットのNAT Gatewayを経由しているかで判断します。
Lambda関数を300回非同期で並列実行する
それでは早速やってみます。
AWS CDKで検証に必要なリソースをデプロイします。
こちらのコードのリポジトリは以下になります。
npx cdk deploy
で各種リソースをデプロイします。
デプロイ後にENIを確認すると、NAT GatewayとLambda関数用のENIが各サブネットで作成されていました。
$ aws ec2 describe-network-interfaces \ --filters Name=vpc-id,Values=vpc-05c8eea6c5100f007 \ --query "NetworkInterfaces[].[InterfaceType,NetworkInterfaceId,AvailabilityZone,PrivateIpAddresses,Description]" \ --output json [ [ "nat_gateway", "eni-04413c1a6d29fdbda", "us-east-1a", [ { "Association": { "AllocationId": "eipalloc-0ec71522aca5ca0f5", "AssociationId": "eipassoc-01327a546f7ba1db0", "IpOwnerId": "<AWSアカウントID>", "PublicDnsName": "ec2-34-231-115-15.compute-1.amazonaws.com", "PublicIp": "34.231.115.15" }, "Primary": true, "PrivateDnsName": "ip-10-10-0-4.ec2.internal", "PrivateIpAddress": "10.10.0.4" } ], "Interface for NAT Gateway nat-0698f65fa4a203b2f" ], [ "lambda", "eni-0bed44e1abe515db3", "us-east-1a", [ { "Primary": true, "PrivateDnsName": "ip-10-10-0-38.ec2.internal", "PrivateIpAddress": "10.10.0.38" } ], "AWS Lambda VPC ENI-VpcLambdaStack-GetNyGlobalIPFunction1F43415E-dDR5sBxFJoWW-e6e4092c-d4ba-4b13-a7f4-ac742b825ed8" ], [ "nat_gateway", "eni-0c4b58c1ca0b8abf9", "us-east-1b", [ { "Association": { "AllocationId": "eipalloc-0eca0e23125c98d81", "AssociationId": "eipassoc-00357bbc8a04d61c8", "IpOwnerId": "<AWSアカウントID>", "PublicDnsName": "ec2-18-209-195-113.compute-1.amazonaws.com", "PublicIp": "18.209.195.113" }, "Primary": true, "PrivateDnsName": "ip-10-10-0-20.ec2.internal", "PrivateIpAddress": "10.10.0.20" } ], "Interface for NAT Gateway nat-0d0d6652a7a05cf11" ], [ "lambda", "eni-0e009ccd468a204ed", "us-east-1b", [ { "Primary": true, "PrivateDnsName": "ip-10-10-0-61.ec2.internal", "PrivateIpAddress": "10.10.0.61" } ], "AWS Lambda VPC ENI-VpcLambdaStack-GetNyGlobalIPFunction1F43415E-dDR5sBxFJoWW-eaea8451-d931-4976-b6e3-16b67b5e1278" ] ]
また、あまり関係ないかもしれませんがサブネットはus-east-1b
、us-east-1a
の順で指定されていました。
それでは、Lambda関数をステートマシン経由で300回非同期実行します。
300回非同期実行する場合は、ステートマシン実行時に以下のJSONを渡します。
{ "numberForInputMap": 300 }
しばらく待つとステートマシンの実行が完了しました。
ちなみに以下AWSブログでも紹介されていますが、ステートマシンの実行画面が新しくなってます。
状態遷移や期間の情報が追加されていて、個人的にかなり嬉しいです。
Table view
をクリックすると、かなりイケている画面が表示されます。これもステート毎の入力や詳細を確認しやすくなっていて嬉しいですね。
ちょっと脇道にそれました。
実行結果をCloudWatch Logs Insightsで集計します。
集計に使用したクエリは以下の通りです。
fields id, response_data | sort id | filter (id>=0) | limit 300
実行した結果は以下の通りです。

が196回、us-east-1b

順番を確認したところ、交互になっているところもあれば、連続して片方のサブネットのIPアドレスが表示されていたりと明らかな法則性は見られませんでした。
何だか不完全燃焼なので、あと3回確認してみます。CloudWatch Logs Insightsの結果は折りたたみます。

追加で3回実行しましたが、明らかな法則性は見つけられませんでした。どうやらどちらのサブネットで起動するかはランダムのようですね。
恐らくランダム
VPC Lambdaで複数のサブネットを指定した場合にどちらのサブネットで動作するか確認してみました。
Lambda関数を300回非同期で並列実行を4セットしたところ、明らかな法則性を見つけることは出来ませんでした。
個人的にはHyperplane ENIのおかげで、VPC Lambdaを300回実行してもいずれも11秒で処理が完了したのが驚きでした。Hyperplane ENIすごい。
この記事が誰かの助けになれば幸いです。
