In this blog post, you learn how to control concurrency in a distributed system. You implement a semaphore using Step Functions and DynamoDB Conditional Expressions. Finally, you use EventBridge to trigger lock cleanup when you encounter failure.

This blog post outlines a general approach to debugging Lambda performance issues and errors. This provides a repeatable process for isolating and resolving problems in your serverless workloads. Using the walkthrough of the Coffee Lookup application, I show how to reproduce a production bug, isolate the cause of errors, and then isolate the performance issue.

This post shows how to deploy an imagery processing pipeline in the AWS Cloud. It is decoupled to allow both pre and post-processing extensions to be integrated into the pipeline more easily. Visit the code repository for further information.

Many existing monitoring and observability concepts also apply to Lambda-based applications. This post introduces key terms, application performance monitoring, with broad metrics can be useful for monitoring workloads.

All the feature launches, blogs, videos, tech talks and more happenings from the AWS Serverless service teams in Q1 2021.

In this post, you learn how to grant Azure Active Directory users Single Sign-On access to the CloudEndure console. You can now create multiple enterprise applications for different CloudEndure accounts. You can use the guide in this post to assign CloudEndure projects or accounts to users.

CloudWatch Logs Insights allows you to search and analyze log data to find the causes of issues and help validate fixes when they are deployed. This post shows how to enable the feature for a Lambda function and search across logs. It explains why structured logging can be helpful for parsing data in analysis.

This article presents an architecture that enables customers to use Step Functions workflow callbacks without exposing the implementation and AWS service details to external systems.

On July 15, 2021, AWS Lambda will deprecate Python 2.7 as a supported runtime, formally ending our Python 2.7 support.

This post explains common integration errors in Lambda-based applications. These include running an unintended version or alias of a function, triggering infinite loops unintentionally, and issues with downstream availability. In each case, I explain steps you can take to remediate the issue.
