はじめに

皆様こんにちは、あかいけです。

先日私はre:Growth 2025にてLambda Managed InstancesとLambda Durable Functionsの話で登壇させていただきました。
その中で 「Lambda Managed Instancesで遂にLambdaでもGPUが使えるぞ！わっしょい！」 というお話をしました。

https://dev.classmethod.jp/articles/regrowth2025-tokyo-lambda-managed-instances-durable-functions/

が、よくよく調査したところ、2025年12月9日時点ではLambda Managed InstancesでGPUインスタンスは利用できない ことが判明しました。
というわけで、お詫びと訂正、並びに確認方法をブログにします。

ドキュメントで確認する

まずLambda Managed Instancesで利用できるインスタンスタイプは、Lambdaの料金ページにて確認ができます。

https://aws.amazon.com/lambda/pricing/

例としてバージニアリージョン、および東京リージョンで記載されているインスタンスタイプは以下の通りです。

  • バージニアリージョン
    • 全483種類、そのうちインスタンスタイプは61種類

確かに上記では、以下公式ドキュメントに記載のGPUインスタンス（g系、p系など）は含まれていませんね…。

https://aws.amazon.com/ec2/instance-types/accelerated-computing/

なお全てのリージョンは確認していませんが、バージニアリージョンが一番対応インスタンスタイプが多かったため、こちらにGPUインスタンスがなければ他のリージョンにもないと判断することとしました。

AWS CLIで確認してみる

諦めきれないので、念のためAWS CLIでも確認してみます。
確認対象はインスタンスタイプが一番多いバージニアリージョンとします。

https://docs.aws.amazon.com/ja_jp/lambda/latest/dg/lambda-managed-instances-capacity-providers.html

まずはキャパシティープロバイダーで指定するリソースを環境変数に埋め込んでおいて、

SubnetId=subnet-XXXXXXXXXXXXXXXXX
SecurityGroupId=sg-XXXXXXXXXXXXXXXXX
CapacityProviderOperatorRoleArn=arn:aws:iam::XXXXXXXXXXXX:role/lambda-managed-instance-role

あとは以下のコマンドを実行します。
コマンドの内容は以下の通りです。

  • aws ec2 describe-instance-types
    • GPUインスタンスのアーキテクチャ（x86_64 or arm64）とインスタンスタイプ名（例: g6.xlarge）をフィルタリング
  • aws lambda create-capacity-provider
    • アーキテクチャとインスタンスタイプをもとにキャパシティープロバイダーを作成
aws ec2 describe-instance-types \
  --region us-east-1 \
  --query "InstanceTypes[?GpuInfo!=null].[InstanceType, ProcessorInfo.SupportedArchitectures[0]]" \
  --output text | sort | while read instance_type arch; do

  aws lambda create-capacity-provider \
    --region us-east-1 \
    --capacity-provider-name "test-${instance_type//./-}" \
    --vpc-config SubnetIds=$SubnetId,SecurityGroupIds=$SecurityGroupId \
    --permissions-config CapacityProviderOperatorRoleArn=$CapacityProviderOperatorRoleArn \
    --instance-requirements "Architectures=$arch,AllowedInstanceTypes=$instance_type" \
    --capacity-provider-scaling-config ScalingMode=Auto \
    2>&1

  sleep 1
done

結果としては以下の通りで、
「全てのGPUインスタンスでキャパシティープロバイダーが作成できない」 = 「該当のインスタンスタイプはLambda Managed Instancesで利用できない」 ことがわかります。

念のためGPUインスタンスに限定するフィルタリングを外して実行すると、

aws ec2 describe-instance-types \
  --region us-east-1 \
  --query "InstanceTypes[].[InstanceType, ProcessorInfo.SupportedArchitectures[0]]" \
  --output text | sort | while read instance_type arch; do

  aws lambda create-capacity-provider \
    --region us-east-1 \
    --capacity-provider-name "test-${instance_type//./-}" \
    --vpc-config SubnetIds=$SubnetId,SecurityGroupIds=$SecurityGroupId \
    --permissions-config CapacityProviderOperatorRoleArn=$CapacityProviderOperatorRoleArn \
    --instance-requirements "Architectures=$arch,AllowedInstanceTypes=$instance_type" \
    --capacity-provider-scaling-config ScalingMode=Auto \
    2>&1

  sleep 1
done

ちゃんと作成できるキャパシティープロバイダーもあるため、AWS CLIのコマンド自体に誤りはないことがわかります。

An error occurred (InvalidParameterValueException) when calling the CreateCapacityProvider operation: The operator role arn:aws:iam::XXXXXXXXXXXX:role/lambda-managed-instance-role doesn't have permission to perform ec2:RunInstances on the capacity provider. Grant the operator role ec2:RunInstances permission and try again.

        },
        "LastModified": "2025-12-12T07:46:02.155592026Z"
    }
}

さらに念のためマネジメントコンソールから確認すると、コマンドと同じエラーが出ることを確認できます。

以上の結果から、Lambda Managed Instancesでは現時点でGPUインスタンスが利用できないことがわかります。

The specified instance type(s) g6.xlarge aren't supported for x86_64 architecture. Choose supported instance types for this architecture.

さいごに

以上、2025年12月9日時点ではLambda Managed InstancesでGPUインスタンスは利用できないというお話でした。

登壇で堂々と誤った情報をお伝えしてしまい、申し訳ございませんでした…。
てっきりGPUインスタンスが使えると思い込んでいたのですが、
登壇後に料金ページやAWS CLIで確認したところ、m系・c系・r系の汎用インスタンスのみ対応していることがわかりました。

とはいえ、Lambda Managed Instancesは発表されたばかりの機能なので、今後GPUインスタンスにも対応する可能性は十分あると思います。
対応されたらまたブログを書きます！

この記事が勘違いさせてしまった方の参考になれば幸いです。
