Operating Lambda: パフォーマンスの最適化 – Part 1 | Amazon Web Services
Amazon Web Services ブログ Operating Lambda: パフォーマンスの最適化 – Part 1 Operating Lambda シリーズでは、AWS Lambda ベースのアプリケーションを管理している開発者、アーキテクト、およびシステム管理者向けの重要なトピックを取り上げます。この 3 部構成のシリーズでは、Lambda ベースのアプリケーションのパフォーマンスの最適化について説明します。 サーバーレスアプリケーションは、並列化と同時実行が容易であることから、非常に高いパフォーマンスを実現することができます。Lambda サービスはスケーリングを自動的に管理しますが、アプリケーションで使用する個々の Lambda 関数を最適化することで、レイテンシーを削減し、スループットを向上させることもできます。 本稿では、Lambda 実行環境のライフサイクルやコール

I occasionally do talks about curl. In these talks I often include a few slides that say something abut curl’s coverage and presence on different platforms. Mostly to boast of course, but also to help explain to the audience how curl has manged to reach its ten billion installations. This is current incarnation of those seven slides in November 2022. I am of course also eager to get your feedback

Operating a Large, Distributed System in a Reliable Way: Practices I Learned
For the past few years, I've been building and operating a large distributed system: the payments system at Uber. I've learned a lot about distributed architecture concepts during this time and seen first-hand how high-load and high-availability systems are challenging not just to build, but to operate as well. Building the system itself is a fun job. Planning how the system will handle 10x/100x t

While Microsoft and Apple don’t release the source code for their operating systems, a good estimate is that it takes around 50 million lines of code to run these software behemoths. The Linux kernel alone holds around 30 million lines, with systemd containing over one million lines on its own, which doesn’t include estimates for the desktop environment or other parts of a standard installation.

Operating Lambda: イベント駆動型アーキテクチャの設計原則 – Part 2 | Amazon Web Services
これらのサービスは Lambda と統合するように設計されており、Infrastructure as code (IAC) を使用してサービス内のリソースを作成、および破棄できます。アプリケーションをインストールしたりサーバーを設定したりすることなく、AWS SDK 経由でこれらのサービスを利用できます。Lambda 関数のコードを使用して、これらのサービスを使用することに習熟することは、適切に設計されたサーバーレスアプリケーションを作成する上で重要なステップです。 抽象化のレベルを理解する Lambda サービスは、Lambda 関数を実行する基盤となるオペレーティングシステム、ハイパーバイザー、ハードウェアへのアクセスを制限します。このサービスはインフラストラクチャを継続的に改善し変更することで、機能の追加、コストの削減、サービスのパフォーマンスの向上を実現します。あなたのコードはLa

Best practices for operating large-scale recommender systems
Ensuring the health of a modern large-scale recommendation system is a very challenging problem. To address this, we need to put in place proper logging, sophisticated exploration policies, develop ML-interpretability tools or even train new ML models to predict/detect issues of the main production model. In this talk, we shine a light on this less-discussed but important area and share some of th

Operating Lambda: パフォーマンスの最適化 – Part 2 | Amazon Web Services
このケースでは、128 MB の場合、関数が完了するまでに平均 11.722 秒かかり、1,000 回の呼び出しに対するコストは $0.024628 となります。メモリを1024MBに増やすと、所要時間の平均は1.465秒になり、コストは0.024638ドルになります。1,000分の1セントのコスト差で、この関数のパフォーマンスは10倍向上しています。 Amazon CloudWatchで関数をモニタリングし、メモリ消費が設定された最大値に近づいた場合にアラームを設定できます。これは、メモリにバウンドされた関数を識別するのに役立ちます。CPU バウンドおよび IO バウンド関数の場合、実行時間を監視することで、より多くの洞察が得られる場合があります。このような場合、メモリを増やすと、コンピューティングまたはネットワークのボトルネックを解消できます。 AWS Lambda Power Tun
