Welcome to Issue #45 of Off-by-none. I’m so glad you joined us! 🎉
Last week, we recapped AWS re:Inforce and looked at the broader AWS security ecosystem. This week, we ponder how companies adopt serverless, look ahead to AWS Summit New York, and share lots of great content from the serverless community.
Tons of stuff to get to this week, so let’s get to it! ⏩
Earlier this week, Tom McLaughlin wrote this piece announcing that he was shutting down ServerlessOps (his cloud/serverless consulting company). The good news is that he will be bringing his expertise and wisdom to Liberty Mutual to help them with their serverless journey, but the bad news is, that another independent consultant is off the market.
Tom offers some insights into why he thinks a small, serverless-focused consultancy business isn’t viable (yet), and I think he’s probably correct for many reasons. There are certainly opportunities for serverless practitioners (of all sizes) to help companies looking to adopt serverless, but there are a lot of factors that drive the internal conversations. I’ve spoken to a number of companies simply looking for guidance, some who want to outsource completely, and some who have just started figuring things out on their own. I think these are all viable ways to get started with serverless. The key is that they are getting started.
However your company plans on adopting serverless, it’s good to know that there are some really good people out there (like Tom was) to help you, especially when you start dealing with complex architectures. I’m sure Tom will continue to share his thoughts and ideas with the serverless community, and maybe even give us some insights into how his new employer adopts serverless. We certainly wish him well.

“From an operations and management standpoint, we don’t need to be the experts at running a MongoDB database. And we don’t need to be experts in running some kind of streaming platform.

Not specific to serverless, but just another example of how popular third-party modules can be compromised.
The Promise and Perils of Serverless Computing
I always appreciate other people’s take on serverless as it’s interesting to see how they frame the advantages and disadvantages. This post by Krishnan Srinath points out the “security” and “vendor lock-in” FUD that are commonly spread. I did find his take on “services sprawl” to be valid.

Loving what @GunnarGrosch did on “Serverless chaos” using the Injection library I built. Got inspired by his feedback so merged his code and added a bunch of functionality: StatusCode, Exception and of course Latency injection!! Thanks mate! https://buff.ly/2Nz9oga ~ Adrian Hornsby
Some good collaboration between Adrian and Gunnar. The more tools we have, and the better we understand how chaos engineering applies to our serverless applications, the more resilient our services will be.
Dear @awscloud, I am a real fan of AWS CloudFormation & Serverless implementation, could we please have the CloudFormation’s 200 resources limit removed. Please a humble request from a #AWS fan. #awswishlist #Serverless ~ Srujal Kachhela
This seems like a pretty straightforward request, but it started an interesting debate. Nested stacks are an eloquent solution.
To me, serverless is about the Developer Experience (DX). If these words are in the conversation, we aren’t talking serverless IMO. And I don’t think it has anything to do with how you pay for it. #serverless ~ Paulo Arruda
I liked this tweet from Paulo. Make sure you click through to see the attached image.
