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 is written by Bryant Bost, Cloud Application Architect. There is not a one-size-fits-all approach to access control for Amazon API Gateway. Properties of your application such as API type, identity provider, client access patterns, privacy requirements, and others influence the design of your access control solution. Understanding the types of access control available […]

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.

Amazon API Gateway recently enhanced base path mapping for custom domains by introducing multi-level base path mapping. Before multi-level base path mapping, paths could not contain a forward slash (/) in a base path. This restriction meant that base paths could only consist of a single word (for example, sales) or a concatenation of several […]

This post is written by Rudolf Potucek, Startup Solutions Architect. Amazon API Gateway REST APIs have supported binary data since 2016. API Gateway HTTP APIs makes it easier to work with both binary and text media types. It supports a new payload format version and infers encoding based on request and response formats. In this […]

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.
