Processing satellite imagery with serverless architecture
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.
Operating Lambda: Logging and custom metrics
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.
Using multiple segments in Amazon API Gateway base path mapping
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 […]
Handling binary data using Amazon API Gateway HTTP APIs
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 […]
Operating Lambda: Using CloudWatch Logs Insights
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.
Integrating AWS Step Functions callbacks and external systems
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.
Announcing end of support for Python 2.7 in AWS Lambda
On July 15, 2021, AWS Lambda will deprecate Python 2.7 as a supported runtime, formally ending our Python 2.7 support.
Operating Lambda: Debugging configurations – Part 3
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.
Building an image searching solution with the AWS CDK
This post discusses a fully serverless architecture for searching images based on their contents. It shows how this architecture is decoupled and stateless by using S3 events, SQS messages, an EventBridge bus, and Amazon Aurora Serverless.
Operating Lambda: Debugging configurations – Part 2
This is the second post in a series on debugging Lambda-based applications. This post shows how to identify and resolve memory and CPU-bound functions, and how to understand and use timeouts effectively in production applications.
