CloudTwin Hands-on (#2) Troubleshoot AWS Lambda invocation issues with Lightlytics Discovery
Blog post from Stream.Security
AWS Lambda, a serverless computing platform from Amazon, allows developers to execute code in response to events without managing the underlying infrastructure. It automatically handles the administration of compute resources, enabling developers to focus on application code. However, troubleshooting issues in distributed serverless applications like Lambda can be complex due to the need to understand the state of various interconnected services. This text discusses a specific troubleshooting scenario with an AWS Lambda function invoked by an Amazon S3 trigger, where an error in fetching an object from an S3 bucket was encountered. The error was traced to a restrictive IAM policy that blocked the "s3:GetObject" action. Lightlytics Discovery is highlighted as a tool that simplifies troubleshooting by analyzing cloud resource configurations and dependencies, allowing users to identify and resolve issues, such as the IAM policy restriction, more efficiently. This tool provides a way to visualize resource relationships and track configuration changes, assisting cloud practitioners in efficiently managing their cloud environments.
