Hi, here’s a quick round-up of everything I have done in August 2023. Real-World Serverless podcast relaunched After a hiatus, the real-world serverless podcast is back and better than ever before. It’s now available on YouTube as well as the usual podcast platforms such as Spotify. This new audio + video format gives guest speakers …
Every now and then you are faced with an awkward situation where you need to wait for a slow HTTP response and it can take more than 15 mins. Using Lambda is impractical because of the 15 mins timeout, and very cost ineffective because you will be paying for all that idle time by the millisecond.
If not Lambda, what’s the most serverless way for you to wait for a sloooow HTTP response?
It’s been a few years since I launched the “Complete Guide to AWS Step Functions” and “Learn you some Lambda best practice for great good!“. And given the diminishing value of these early courses I feel it’s only right that I stop charging for them. So from now on, you can sign up for these …

I had a really good question from one of my students at the Production-Ready Serverless workshop the other day: “I’m reacting to S3 events received via an SNS topic and debating the merits of having the Lambda triggered directly by the SNS or having an SQS queue. I can see the advantage of the queue …

In my last conversation with Ben Kehoe on the real-world serverless podcast, he said something profound and it’s been bugging me ever since. And now I’m ready to infect you with this brain bug! You’re welcome ;-) On the infrastructure-from-code trend, Ben said: “I think infrastructure-from-code is wrong on all counts. I don’t think we should …

When I previously wrote about testing Step Functions, I gave you a general strategy that consists of: Component tests that target the Lambda functions (specifically, the custom code you wrote in those functions). End-to-end tests that execute the state machine in the cloud. Local tests using Step Functions Local where you can use mocks to …

Several people have asked me about unit testing CDK applications recently. The questions often go something like this: “Because it can be in Python or TS, people bring up unit testing for CDK, whereas it’s not even thought about with Serverless Framework, SAM or Terraform. What are your thoughts on this?” “I have so many …
No, you don’t need to test every line of your CDK application Read More »
The PrimeVideo team’s move from serverless caused much stir, but most people got it wrong because they read the article with tinted glasses.
This is what they actually said.
Ask most developers why they like the CDK and they will say “It lets me write infrastructure in my favourite programming language”. That’s nice, but why should that be a consideration for an Infra-as-Code (IaC) tool? That’s like saying “I like Strepsils because it tastes like candy”. ps. if you mention candy, pharmacy staff would …

Yesterday, I posted a tweet with an imaginary conversation that is sadly based on many real conversations I have had. The tweet received some interesting replies, and the point about spending limits came up multiple times. So as a thought experiment, let’s think about the pros and cons of a spending limit and if it …
