This post explores Lambda’s scaling behavior when subscribed to SQS standard queues. It walks through several ways to scale faster and maximize Lambda throughput when needed. This includes increasing the memory allocation for the Lambda function, increasing batch size, catching errors, and making configuration changes.

In this post, you build a highly available Amazon MQ broker in a private subnet. You layer security by placing the brokers behind a highly scalable Network Load Balancer. You configure routing from a single custom subdomain URL to multiple brokers with a built-in health check.

This post is written by Veda Raman, SA Serverless, Casey Gerena, Sr Lab Engineer, Dan Fox, Principal Serverless SA. For real-time machine learning inferencing, customers often have several machine learning models trained for specific use-cases. For each inference request, the model must be chosen dynamically based on the input parameters. This blog post walks through the architecture […]

This post shows how to create a Step Functions workflow for Forecast using AWS SDK service integrations, which allows you to use over 200 with AWS API actions. It shows two patterns for handling asynchronous tasks. The first pattern queries the describe-* API repeatedly and the second pattern uses the “Retry” option. This simplifies the development of workflows because in many cases they can replace Lambda functions.

This solution provides a way to convert information from Secrets Manager into Lambda environment variables. By following this approach, you can centralize the management of information through Secrets Manager, instead of at the function level.

There are multiple factors to consider when tuning a federated GQL system. You must be aware of trade-offs when deciding on factors like the runtime environment of Lambda functions. An extensive testing strategy can help you scale systems and narrow down issues quickly. Well-defined testing can also keep pipelines clean of false-positive blockages.

This blog post shows how to create a scalable difference checking tool for objects stored in S3 buckets. The Lambda function is invoked when S3 writes new versions of an object to the bucket. This example also shows how to remove earlier versions of object and define a set number of versions to retain.

This blog post shows how to use Step Functions’ features and integrations to orchestrate a batch processing solution. You use two Steps Functions workflows to implement batch processing, with one workflow splitting the original file and a second workflow processing each chunk file.

This post describes guardrails that you can set up in your accounts or across the organization to keep control over deployed resources. These guardrails can be more or less restrictive according to your requirements.

This blog shows an event driven approach to handling dynamic SNS subscription requirements. It relies on the ECS service events to trigger appropriate Lambda functions. These create the subscription queue, subscribe it to a topic, and delete it once the container instance is terminated.
