Hi, welcome to another weekly update :-)
Getting the most out of CloudWatch Logs. In this post, I took a deep dive into the CloudWatch Logs service, looking at how it works, its features (including metric filters and CloudWatch Logs Insights) as well as limitations.
How to do blue-green deployment for Step Functions. In this post, I explained the challenges with making changes to your state machine while there are running executions. I offered a solution (and a demo) which relies on referencing specific version/alias instead of the default Lambda function ARN. This allows you to make changes to the state machine without breaking existing executions.
How to make Serverless framework boilerplates customizable. In this post, I illustrated two solutions for when you need to customize some boilerplate configuration for your serverless.yml – using Yaml anchors and using ES6 Proxy class for a js file.
Serverless Step Functions: no more leaky abstractions. I announced a small but significant change to the serverless-step-functions plugin, to allow you to reference local functions (those defined in the same serverless.yml) using their local name (e.g. hello-world) rather than the generated CloudFormation name (e.g. HelloDashworldLambdaFunction)
