The Serverless Framework remains a top choice for serverless development, as evidenced by the recent State of Serverless report [1]. Yet, its appeal has waned over time due to the lack of innovation in recent years, prompting users to explore other options. Recently, they announced [2] significant updates for Serverless v4: Fees will be introduced …

Sharing code efficiently across different parts of an application can be challenging with AWS Lambda, especially when using Amplify. Today, I’ll walk you through a solution to this common problem, without relying on Lambda Layers or private NPM repositories. The Context In my previous post about Lambda Layers [1], I delved into its limitations, especially …

Having taught thousands of students to build serverless applications via my online courses and workshops, I felt it was time to kick-start an affiliate program to boost sales. Affiliates would receive 50% of the revenue and get a 15% discount code for their audience. It feels like a good deal but I would need a …

It’s a good practice to use CloudFormation’s deletion policy to protect stateful resources such as DynamoDB tables or RDS databases from accidental deletions. Such as when someone accidentally deletes a CloudFormation stack! As I discussed previously [1], this is a much better way to guard against these accidental data losses than separating stateful and stateless …

Many vendors require you to have a static IP address for your application. Such that all requests to their API must originate from an allow-list of IP addresses. This means we need to force egress traffic from our Lambda functions through a static IP address. Sometimes, they even mandate that you use a static IP …

Step Functions’ state machines come in two flavours. By understanding their strengths and limitations, you can harness the combined power of both to optimize your processes for efficiency and cost. Standard Workflows Optimal for: Business-critical operations like payment processing. Strengths: Suitable for low-throughput scenarios. High maximum duration ensures enough time for retries using exponential backoff. …

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 …
