How to operate reliable AWS Lambda applications in production
running a reliable Lambda application in production requires you to still follow operational best practices. In this article I am including some recommendations, based on my experience with operations in general as well as working with AWS Lambda.

AWS Lambda Deployment using Terraform – Build ACL – Medium
Fairly persuasive that production usage of Lambda is much easier if you go full Terraform to manage and deploy.
A complete picture of what it takes to deploy your Lambda function to production with the same diligence you apply to any other codebase using Terraform. [...] There are many cases where frameworks such as SAM or Serverless are not enough. You need more than that for a highly integrated Lambda function. In such cases, it’s easier to simply use Terraform.

How Did I “Hack” AWS Lambda to Run Docker Containers?

AWS Greengrass
AWS Greengrass is software that lets you run local compute, messaging & data caching for connected devices in a secure way. With AWS Greengrass, connected devices can run AWS Lambda functions, keep device data in sync, and communicate with other devices securely – even when not connected to the Internet. Using AWS Lambda, Greengrass ensures your IoT devices can respond quickly to local events, operate with intermittent connections, and minimize the cost of transmitting IoT data to the cloud.

AWS Greengrass seamlessly extends AWS to devices so they can act locally on the data they generate, while still using the cloud for management, analytics, and durable storage. With Greengrass, you can use familiar languages and programming models to create and test your device software in the cloud, and then deploy it to your devices. AWS Greengrass can be programmed to filter device data and only transmit necessary information back to the cloud. AWS Greengrass authenticates and encrypts device data at all points of connection using AWS IoT’s security and access management capabilities. This way data is never exchanged between devices when they communicate with each other and the cloud without proven identity.

The Occasional Chaos of AWS Lambda Runtime Performance
If our code has modest resource requirements, and can tolerate large changes in performance, then it makes sense to start with the least amount of memory necessary. On the other hand, if consistency is important, the best way to achieve that is by cranking the memory setting all the way up to 1536MB.
It’s also worth noting here that CPU-bound Lambdas may be cheaper to run over time with a higher memory setting, as Jim Conning describes in his article, “AWS Lambda: Faster is Cheaper”. In our tests, we haven’t seen conclusive evidence of that behavior, but much more data is required to draw any strong conclusions.
The other lesson learned is that Lambda benchmarks should be gathered over the course of days, not hours or minutes, in order to provide actionable information. Otherwise, it’s possible to see very impressive performance from a Lambda that might later dramatically change for the worse, and any decisions made based on that information will be rendered useless.

3 Reasons AWS Lambda Is Not Ready for Prime Time
This totally matches my own preconceptions ;)
When we at Datawire tried to actually use Lambda for a real-world HTTP-based microservice [...], we found some uncool things that make Lambda not yet ready for the world we live in:

Lambda is a building block, not a tool;
Lambda is not well documented;
Lambda is terrible at error handling

Lung skips these uncool things, which makes sense because they’d make the tutorial collapse under its own weight, but you can’t skip them if you want to work in the real world. (Note that if you’re using Lambda for event handling within the AWS world, your life will be easier. But the really interesting case in the microservice world is Lambda and HTTP.)

A Gulp Workflow for Amazon Lambda
'any nontrivial development of Lambda functions will require a simple, automated build/deploy process that also fills a couple of Lambda’s gaps such as the use of node modules and environment variables.'

See also https://medium.com/@AdamRNeary/developing-and-testing-amazon-lambda-functions-e590fac85df4#.mz0a4qk3j : 'I am psyched about Amazon’s new Lambda service for asynchronous task processing, but the ideal development and testing cycle is really left to the engineer. While Amazon provides a web-based console, I prefer an approach that uses Mocha. Below you will find the gritty details using Kinesis events as a sample input.'

Schedule Recurring AWS Lambda Invocations With The Unreliable Town Clock (UTC)
The Unreliable Town Clock (UTC) is a new, free, public SNS Topic (Amazon Simple Notification Service) that broadcasts a “chime” message every quarter hour to all subscribers. It can send the chimes to AWS Lambda functions, SQS queues, and email addresses.

You can use the chime attributes to run your code every fifteen minutes, or only run your code once an hour (e.g., when minute == "00") or once a day (e.g., when hour == "00" and minute == "00") or any other series of intervals. You can even subscribe a function you only want to run only once at a specific time in the future: Have the function ignore all invocations until it’s after the time it wants. When it is time, it can perform its job, then unsubscribe itself from the SNS Topic.

AWS Lambda Event-Driven Architecture With Amazon SNS
Any message posted to an SNS topic can trigger the execution of custom code you have written, but you don’t have to maintain any infrastructure to keep that code available to listen for those events and you don’t have to pay for any infrastructure when the code is not being run. This is, in my opinion, the first time that Amazon can truly say that AWS Lambda is event-driven, as we now have a central, independent, event management system (SNS) where any authorized entity can trigger the event (post a message to a topic) and any authorized AWS Lambda function can listen for the event, and neither has to know about the other.
