I've been exploring ways to optimize my AWS Lambda costs, but the typical cloud cost tools often only suggest basic adjustments like increasing memory or reducing timeouts. I'm looking for tools that can identify deeper issues such as functions with idle provisioned concurrency, dead code that bloats package sizes and cold starts, event-triggered functions that could be batched, retry storms from faulty error handling, and even recursive invocation loops. I want to find solutions that not only report spend by function but also explain why a function costs what it does and provide actionable steps to fix it. What are you using that goes beyond basic recommendations? Bonus points for any tools that integrate seamlessly into existing workflows.

Hey! When it comes to optimizing AWS Lambda, the main costs come from the total number of invocations, execution time, and memory allocated. It's really not that complicated. If you're seeing high costs, a robust Application Performance Monitoring (APM) tool can help you experiment with new workflows. You might already have enough insights just from CloudWatch, and tools like X-Ray can pinpoint problem areas if set up correctly.

I agree! APM tools like CloudWatch or X-Ray can really give you the insights you need. But remember to look into Amdahl’s Law before diving too deep; often, the effort for optimization doesn’t yield enough savings to justify the time.
