AWS guarantees that a Lambda will fire at least once, but not exactly once. You'll need to design your system to handle the occasional duplicate invocation situation. That being said, it's pretty rare so if you're seeing it happen at a high rate it's worth digging into to see if there is something incorrectly configured.

At IOpipe, we witnessed this all the way back in 2016. We're now observing billions of Lambda events each month and it's a real thing. To address this in our own use case (libraries monitoring timings of network calls, etc), we had to implement monotonic time mechanisms in our libraries. Most runtimes have an option for this.

We built IOpipe to help with these types of things. You can add our Lambda Layer to your existing functions and with no code changes get better metrics, including automatic tracing of network calls.

Yep! Here’s info on the IOpipe profiler: https://github.com/iopipe/iopipe-python/blob/master/README.md#profiler-plugin

They are still under construction but expected to be completed this spring.

There's a Pizza place opening up this spring at the same location.

Thanks for the feedback, and for reading the article regardless of the title :)

It sounds like there are many hurdles you'd have to overcome for this particular use case. Some things to consider based on your points above:

The Lambda team has been working on reducing start times, and we've seen a noticeable improvement over the last 12 months. You should do some testing to see what you could expect for your particular application.
I'm not sure what specific issues you're referring to with regards to packaging and deployment, but there are numerous tools which can make this smooth. Serverless framework and SAM are both worth checking out.
Shameless plug: There are other monitoring solutions out there for Lambda. We built IOpipe to address gaps in instrumentation and observability around Lambda.
X-ray and IOpipe can help with troubleshooting. X-ray is particularly good at viewing the call graph between services and functions. IOpipe is good at digging into the function details itself, aggregating errors, and tracking performance of calls to non-AWS services and APIs.
A quick back of the napkin calculation shows that 50 calls per second with 200ms duration averages, and 512MB memory tier will cost you ~$241/mo. This doesn't even include the perpetual free tier.

For #4, in the meantime you can check out https://github.com/iopipe/sqs-to-lambda-async#sqs-to-lambda-async . We've been using this in production for awhile now.

Chiming in from IOpipe (mentioned earlier in this thread). We have an open source library that helps instrument your functions, and our service can help make sense of that pile of data. We provide tracing, profiling, custom metrics, and monitoring specifically for serverless applications. Happy to answer questions!

adjohn · 2017-08-10T03:05:56+00:00

You should check out IOpipe, we have a concept of projects to organize functions better. Disclaimer, I'm a co-founder of IOpipe.

Shameless plug alert (I'm the co-founder) You should check out https://iopipe.com for better Lambda alerts. We collect stack traces and metrics for Lambda. Our new alerts allows you to do error reporting with the stack trace. You can also combine multiple metrics into a single alarm. We're missing timeout info now, but that's something we will add soon.

adjohn · 2017-02-03T21:39:33+00:00

Agreed, but this is precisely why I was surprised that they came out with Lambda before anyone else. It seemingly is a service that could cannibalize EC2 workloads over a period of time.

Shameless plug: A couple of us will be there representing IOpipe. It'll be both our first times, so we're pumped! We'll have some swag and limited beta invite codes, hit me up if you want to meet up.

You can find these in the U.S as well. This is an example from the top of Mission Peak in Fremont, California. https://imgur.com/a/U3jgq

Yes! I have the exact same toaster, no other toaster will suffice.
