Welcome to Issue #31 of Off-by-none. It’s great to have you here. 🙇♂️
Last week we looked at Event Fork Pipelines and explored the security model of Lambda. This week, the Serverless Framework goes Enterprise, we look at some serverless security trends, and share more great content from the serverless community.
Plenty happening with serverless this past week, so let’s get right to the good stuff!
Announcing Serverless Framework Enterprise: The Total Serverless Solution
I’m a HUGE fan of the Serverless Framework, and the new features launching with the Serverless Enterprise Framework are a great addition to help make deploying serverless applications easier AND safer. Insights, Secrets, and Safeguards, are three very useful services (that I’ve seen first hand) that should streamline your serverless development process.
Vizion.ai launches its managed Elasticsearch service
Also a huge fan of Elasticsearch, but even when using AWS’s managed service, there is still the issue of provisioning. Vizion.ai is trying to change that by scaling ES automatically and bringing the cost down using some sort of innovative caching. Serverless Elasticsearch would be a useful addition to the ecosystem.
Consume a RabbitMQ message from AWS Lambda
Curtis Strain’s last post was about publishing messages to RabbitMQ. This time he shows us how to consume them. And yes, I actually have a need for this. 🤦🏻♂️
A Serverless application to clean up old deployment packages
Yan Cui teamed up with Lumigo and created a Serverless Application Repository service called Lambda-Janitor that will clean up all those old deployment packages to keep you under the limit.
Building a Fully Serverless Realtime CMS using AWS AppSync and Aurora Serverless
There are a lot of people building content management solutions with serverless, and Yi Ai is joining in the fun. A CMS is a great use case for serverless, especially given the extremely infrequent computing power needed.
A Smart Service to Keep AWS Lambda Warm
Renato Byrro from Dashbird is continuing to pull the thread on warming Lambdas. This post takes an interesting approach by positing a predictive algorithm that could better understand concurrency models. Using CloudWatch metrics to make better decisions, hmm, that’s a novel idea. 😉
Building CICD pipelines for serverless microservices using the AWS CDK
Paul Swail has another installment in his Migrating a Monolithic SaaS App to Serverless series. This time he’s building out a CI/CD pipeline using AWS CDK to configure the infrastructure.
Uploading images to AWS from remote devices securely via Rest API using AWS
It’s perfectly plausible that you’d need images (or other files) uploading from remote devices, Sandip Pradhan will show you how to do it securely.
Serverless computing: 6 things you need to know
Jeffery Hammond from Forrester Research gives an excellent interview explaining what serverless is and why it is so important.
Serverless Technology Overtakes Cloud Computing
If you need to convince your boss that your company should be adopting serverless, point them to this CIOReview article. It’s a nice little executive summary that lays out the benefits in just a few paragraphs.
Compare AWS Lambda to Azure, GCP serverless platforms
There are a lot of “serverless” offerings out there, but the big three are still dominating the market. This piece by Chris Moyer lays out some of the differences between them.
Comparing Nuclio and AWS Lambda
If you like comparisons, check out Yan Cui’s piece that looks at how the open-source Nuclio project compares to Lambda. Yan recommends exploring Nuclio if you are looking for a serverless platform that isn’t tied to a specific cloud provider.
When’s the right time to go serverless?
I say, RIGHT NOW! But according to Chip Childers, serverless is still in the “pre-chasm” phase, which means best practices and tools still haven’t evolved yet. While I believe that is true to some extent, the market is catching up very quickly.
Kurtis Kemple is realizing the power that managed services stitched together with FaaS and frontend frameworks can bring.
Don’t Code If You Don’t Have To When Serverless
Tom McLaughlin of ServerlessOps also had an “aha” moment when he realized he could wire PagerDuty directly into CloudWatch and didn’t need to write (and support) more code. Take a look at your serverless functions and try to figure out what doesn’t need to be there. I bet there’s more than you think.
Orchestrating backend services with AWS Step Functions
If you need to compose several reusable functions together, AWS Step Functions is the way to go. Jay Dadhania gives a great overview and walks you through setting up workflows to pass your state from step to step.
Mastering Java Cold Starts on AWS Lambda — VOLUME 1
Serkan Özal goes into an insane amount of detail trying to reduce Java cold starts in Lambda. If you’re a Java shop, more power to you. My advice if you’re going serverless, switch to another language with lower start up times.
How to send text messages from your static site using Netlify, Twilio and serverless functions
Static sites with serverless backends are all the rage, and rightfully so. Stefan Judis has an in-depth post that takes you through the process of connecting all the pieces.

Mohit Cheppudira shows you how to build a full-blown (reliable) serverless application using Google Cloud.
Serverless, shadow APIs and Denial of Wallet attacks
In this podcast, Doug Dooley makes a great point about the number of serverless APIs being published, likely unbeknownst to the enterprise. With developers having the ability to launch more services without needing support and guidance from a traditional Ops team, it does beg the question of how we should be keeping track of all these things.
The Serverless Cloud Security Model: A Point Of View
Great piece that lays out a serverless security model based on a validated and battle-tested reference architecture. Definitely worth taking a look at if you’re interested in serverless security (as we all should be).
Local Policy Updates – Keep Your Functions Secure Anywhere (Even In a closed VPC)
Local Policy Updates let you use the PureSec CLI tool to fetch the latest security policy and enforce it on your function during the CI/CD process, eliminating the need to to call the PureSec service at runtime.
Amazon Web Services sharpens its focus on cloud security
This SiliconAngle story recaps last week’s AWS Summit, and gives a good summary of why AWS is continuing to focus on cloud security.

There is a very long list of people that are doing #ServerlessGood and contributing to the Serverless community. These people deserve recognition for their efforts. So each week, I will mention someone whose recent contribution really stood out to me. I love meeting new people, so if you know someone who deserves recognition, please let me know.
This week’s star is Richard Boyd (@rchrdbyd). Richard is a Cloud Data Engineer at The iRobot Corporation who used to work on Robotics and Alexa at Amazon. Now he’s jumping into the serverless community by posting really interesting articles on his blog (rboyd.dev), engaging on Twitter, and collaborating with others. I love hearing new serverless voices and perspectives, and Richard is a very welcome addition to the community. Looking forward to seeing more from him. 👏
The last two weeks have been very busy for me, but we finally have the new AlertMe serverless article processing system up and running in production. Lots of interesting lessons learned there, so perhaps, at some point I’ll share all the details. There is always more to do, but our architecture makes extensibility extremely easy. I’m really looking forward to iterating on the live service.
Don’t forget that next week I’ll be speaking at the Serverless Architecture Conference in The Hague, Netherlands. I’m giving two talks, Serverless Microservice Patterns for AWS and Building resilient serverless Systems with non-serverless Components. I hope to see some of you there. Please come and say “Hi” if you get a chance. I’ve got plenty of “Off-by-none” stickers to give out.
