In this blog post, you learn how to run external transactions securely on Db2 for IBM i databases using a combination of Amazon ECR and AWS Lambda. By using Docker to package the driver, forwarder, and custom queries, you can execute transactions from Lambda, allowing modern architectures to interface directly with Db2 workloads. Get started by cloning the GitHub repository and following the deployment instructions.

This conversion example shows how Step Functions can help you rewrite complex batch processes written in JCL to serverless workflows. It also shows how such a conversion provides maintenance and monitoring features that make it easier to simplify and scale these batch processes.

In this post, you learn how to create a serverless integration Lambda function between API Gateway and Apache Managed Streaming for Apache Kafka (MSK). We show how to deploy such an integration with the CDK.

In this post, you learn how to improve Node.js cold start performance by up to 70% by bundling and minifying your code. You also learned how to provide a different version of AWS SDK for JavaScript and that dependencies and how they are imported affects the performance of Node.js Lambda functions. To achieve the best performance, use AWS SDK V3, bundle and minify your code, and avoid top-level imports.

Event-driven architectures and EventBridge can help you accelerate feature velocity and build scalable, fault tolerant applications. This post demonstrates how to send EventBridge events to a private endpoint in a VPC using a Lambda function to relay events and emit response events. 

This post covers the API Gateway usage plan feature to protect multi-tenant APIs from excessive request loads and also as a product offering that enforces customer specific usage quotas.

This blog post explores how to integrate Amazon AppFlow and AWS Glue using Step Functions to automate your business requirements. You can use AWS Lambda to simplify the configuration phase and reduce state transitions or create complex checks, filters, or even data cleansing and preparation.

Cost optimization is an important part of creating well-architected solutions and this is no different when using serverless. This blog series explores some best practice techniques to help reduce your Lambda bill.

This blog post explains how Lambda pricing works and how right-sizing applications and tuning them for performance efficiency offers a more cost-efficient utilization model. The results can also reduce latency, creating a better experience for your end users.

This blog post outlines how to use Step Functions, Lambda, SQS, DynamoDB, and S3 to create a workflow that automates the testing of EventBridge events. With this example, you can send events to the EventBridge Event Tester endpoint to verify that event delivery is successful or identify the root cause for event delivery failures.
