AWS Lambda apps to automate chores around CloudWatch Logs

The open source applications described in this article are designed to simplify the process of shipping logs from CloudWatch Logs to external services. The first application, auto-subscribe-log-group-to-arn, automates the subscription of log groups to a destination ARN, handling permissions complexity and allowing for customization of the subscription filter. A second application, auto-update retention policy, automates the update of retention policies for log groups, helping users save on storage costs by automatically archiving logs after a specified period. Both applications are available from Lumigo's Github repository and can be deployed to an AWS account through the Serverless Application Repository console. The code for these applications is also publicly available on Github, allowing contributors to raise feature requests and contribute to the project via pull requests.
