【AWS】Terraformで拡張するStepFunctionsを構築しよう！ #stepfunctions – Qiita こんにちは。この記事は「2025 Japan AWS Jr. Chanpions 夏のQiitaリレー」の12日目の記事です。過去の投稿（リンク集）はこちらからご覧ください！本記事はTerraformを使って拡張するStepFunctions構築紹介記事となります。タイトルからイメージするのが難しいと思うので概要と想定状況についてまずは説明いたします。本記事で紹介すること簡単に言うと下記のようなstore_codesの中にコードを追加するだけで locals { store_codes = [ "01", "02", "03", "04", #例えばこの二つを追加すると "05" #例えばこの二つを追加すると ] } 下記のように並列に処理を追加していくStepFunctionsステートマシンの構築をするTerraformコードの紹介となります。 store_codesの中に"04" "05"を追加することで下記のようにステートマシンが拡張される。使いどころ例えば下記のようにお店ごとにサーバーを用意し、そのサーバーに特定のバッチ処理が必要な場合にStepFunctionsでバッチ処理をLambda関数で実装しStepFunctionsをスケジュールで実行するということがあると思います。この時、継続的にお店が増えていく場合、このステートマシンにそのお店用の処理を追加していく必要があります。これをTerraformで、store_codesにお店コードを追加するだけで、ステートマシンを拡張してくれるのでお店追加作業が楽になるというものになります。本記事で紹介するソースは下記に公開しております。 Terraformのフォルダ構成は下記のようになります。 . └── project/ ├── main/ │ ├── local.tf │ ├── main.tf │ └── provider.tf │ └── module/ ├── iam/ │ ├── output.tf │ ├── resource_iam.tf │ └── variables.tf ├── lambda/ │ ├── lambda_code/ │ │ ├── test-lambda.py │ │ └── test-lambda.zip │ ├── output.tf │ ├── resource_lambda.tf │ └── variables.tf └── sfsm/ ├── resource_sfsm.tf ├── sfsm_definition.json └── variables.tf …

Vacuum your Apache Iceberg table with Athena and Step Functions with this Terraform module Apache Iceberg tables are a cost-effective solution to store tabular data, run ACID transactions and analytics at scale, and effectively the foundation of most data lakes. However, since Iceberg tables retain snapshot data (enabling time travel queries), as data gets updated the table storage can grow indefinitely. Vacuum is then required to expire snapshots and remove orphan data files. ## How Apache Iceberg stores your data I'll quote from the Apache Iceberg documentation there: > Table state is maintained in metadata files. All changes to table state create a new metadata file and replace the old metadata with an atomic swap. The table metadata file tracks the table schema, partitioning config, custom properties, and snapshots of the table contents. A snapshot represents the state of a table at some time and is used to access the complete set of data files in the table. As update, delete and insert queries are performed on your Iceberg table, for instance when performing Change Data Capture on a relational database with Firehose, your table storage grows. Vacuuming it will save you a lot on storage. Vacuuming a table can be done in multiple ways (using Glue or any Iceberg client, for instance). Using Amazon Athena is an interesting approach as the compute used to perform vacuuming is provided for free by AWS (whatever the solution, you still pay for the underlying S3 queries). ## Introducing the Iceberg Vacuum Cleaner Terraform module Today, I'm glad to release the Iceberg Vacuum Cleaner Terraform module, that will help you deploy a serverless solution to perform vacuuming of your whole Database. This module will deploy an AWS Step Functions state machine (and an EventBridge Scheduler) that will: * list all Iceberg table within a user-defined Glue database * for each table, perform a "VACUUM " query using Amazon Athena. ## How the Iceberg Vacuum Cleaner vacuums a full Iceberg-based database Two types of state machines are provided: 1. **Sequential queries** : this mode enables you to vacuum tables one by one. While slower, it will not consume your AWS Athena DML quota 2. **Concurrent queries** : a Map state will trigger a sub workflow for each table. In both cases, the state machine will perform retries: * If Athena rejects a StartQueryExecution API call by throwing a TooManyRequestsException (which means you've reach the max concurrency... ask for a Quota increase to speed up the process) * If Athena Query Execution fails with the "ICEBERG_VACUUM_MORE_RUNS_NEEDED: Removed 20000 files in this round of vacuum" error, which means it needs to be ran again the finish the vacuuming process. ## A cost-effective solution Apart from S3 costs (which you'll pay whatever the solution) you'll pay only for the Step Functions state transitions $0.025 per 1000 transitions (with 4,000 transitions included in monthly free tier). I've run these step functions workflow on a 80 tables database. * Sequential run used 300 state transitions (costing $0.0075, yes that's less than a cent!) and lasted 4h21min * Concurrent run (with the default 20 DML quota) used 650 state transitions, costing $0.01625, running for 1h20min. I hope you'll enjoy this solution! If you do or hit any difficulty in using this module, please provide feedback here or via GitHub!

AWSコスト監視くん – AWSのコストをSlackに通知するTerraformモジュール #stepfunctions – Qiita このモジュールを作成するきっかけとなったのは、「AWS Step Functions(JSONata)でAWS料金をSlackへ通知【Lambda無し】」という記事でした。この記事を読んで、Lambdaを使用せずにAWSのコストを監視できる仕組みに感銘を受けたスタッフが「これを導入したい！」ということで、これをTerraformモジュールとして再利用可能な形にさせて頂きました。 AWSの利用コストを監視することは、クラウド運用において重要な課題の一つです。特に、予期せぬコストの増加や、特定のサービスの利用状況を把握することは、コスト最適化の第一歩となります。しかし、AWSのコスト管理コンソールを毎日確認するのは手間がかかり、また、コストの急激な増加に気づくのが遅れる可能性があります。「AWSコスト監視くん」は、以下の機能を提供します。 AWSのコストを定期的に自動確認コストが設定した閾値を超えた場合、Slackに通知コストの内訳をサービスごとに表示カスタマイズ可能なスケジュール設定このモジュールは、AWS Step Functions、SNS、Chatbot、EventBridge Schedulerを組み合わせて実装されています。Lambdaを使用せずに実装されているため、運用コストを抑えることができます。モジュールを呼び出すTerraformコードを作成します。 module "cost_watcher" { source = "../../modules/cost-watcher" project = "my-project" slack_channel_id = "C0123456789" slack_workspace_id = "T0123456789" cost_lookback_days = 7 angry_threshold = 100 batch_schedule = "cron(0 9 ? * MON-FRI *)" batch_timezone = "Asia/Tokyo" } 必要な変数を設定します。変数名説明デフォルト値 project プロジェクト名 - slack_channel_id SlackチャンネルID - slack_workspace_id SlackワークスペースID - cost_lookback_days コストを確認する日数 7 angry_threshold コスト監視くんが怒る閾値（USD） 100 batch_schedule コスト確認のスケジュール（cron形式） cron(0 9 ? * MON-FRI *) batch_timezone スケジュールのタイムゾーン Asia/Tokyo Terraformを実行してデプロイします。 ※詳しくはリポジトリの README をご覧ください。終わりに「AWSコスト監視くん」は、AWSのコスト管理を自動化し、コストの急激な増加を早期に検知することを可能にします。このモジュールを使用することで、コスト管理の効率化と、予期せぬコストの増加を防ぐことができます。 AWSのコスト管理は、クラウド運用において重要な要素です。「AWSコスト監視くん」を使用して、効率的なコスト管理を実現しましょう。この記事良かったと少しでも思って頂けたら是非 @___nix___ をフォローしてあげてください。或いは記事に対してリアクションをお願い致します。この記事は、以下を参考にインスパイアされました。この記事の著者である川原＠Classmethod様に感謝申し上げます。 Source link

Leveraging on-premises APIs in cloud-based event-driven architectures Your company owns important, and sometimes critical, private APIs that reside on-premises and you would like to leverage them in workloads deployed on AWS. More precisely, you would like to make them part of your event-driven architecture, triggered by events or part of complex workflows. This blog post explains how you can leverage new capabilities from Amazon EventBridge and AWS Step Functions to easily trigger/call on-premises APIs without compromising on security.
