Weekly update 30

You can become a serverless blackbelt. Enrol to my 4-week online workshop Production-Ready Serverless and gain hands-on experience building something from scratch using serverless technologies. At the end of the workshop, you should have a broader view of the challenges you will face as your serverless architecture matures and expands. You should also have a firm grasp on when serverless is a good fit for your system as well as common pitfalls you need to avoid. Sign up now and get 15% discount with the code yanprs15!

Hi, welcome to another weekly update :-)

Let’s welcome Blue Matador as this month’s sponsor!

Blue Matador is monitoring alert automation for AWS and Kubernetes environments. Our proactive alerts take the time and toil out of monitoring. Trying to understand baselines and thresholds, and configuring alerts, especially in black boxes like Lambda and K8s, requires significant time and effort. Unlike all the other monitoring tools on the market, Blue Matador eliminates the need to manually configure alerts. After a quick and easy setup, Blue Matador instantly discovers all of your resources, automatically creates hundreds of alerts out-of-the-box and proactively notifies you of critical production issues. We’re so confident you’ll love Blue Matador we’re offering $100 to demo it with our team.

New posts

Amazon EventBridge: a new era of SaaS integration. In this post, I discussed why the newly announced EventBridge service is important. Why it’s just the rebranding CloudWatch Events needs to get the recognization it deserves. And why it can potentially usher a new era of SaaS integration by removing the traditional friction and overhead of integrating with SaaS partners.

CloudFormation Ref and GetAtt cheatsheet. Over the years, I have lost count of the times I had to refer to AWS docs to see if CloudFormation Ref returns an ARN or ID or name or something else! So I put together a quick cheatsheet of the Ref and GetAtt return values by resource type so you can quickly look them up in one place.

How to connect SNS to Kinesis for cross-account delivery via API Gateway. In this post, I illustrated how you can connect SNS directly to Kinesis for cross-account delivery. This was prompted by a question from my friends at DAZN where they experienced concurrency issues with their cross-account delivery mechanism with SNS -> SQS -> Lambda -> Kinesis. As an added bonus, I also illustrated how you can write an execute-once-only Kinesis function by leveraging Lambda’s built-in metaprogramming capability.

Introducing a better way to record custom metrics. I published a new serverless application that makes it easy for you to record custom CloudWatch metrics from Lambda and publish them asynchronously. In a piece of related news, CloudWatch Logs Insight now supports querying multiple log groups!


I made a guest appearance on Heitor Lessa‘s excellent Twitch series – Build On Serverless. I joined Heitor on the two most recent episodes to talk about serverless observability. You can watch recordings of the two episodes here:

Hi, I’m Yan. I’m an AWS Serverless Hero and I help companies go faster for less by adopting serverless technologies successfully.

Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.

Hire me.

Skill up your serverless game with this hands-on workshop.

My 4-week Production-Ready Serverless online workshop is back!

This course takes you through building a production-ready serverless web application from testing, deployment, security, all the way through to observability. The motivation for this course is to give you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands.

We will start at the basics and give you a firm introduction to Lambda and all the relevant concepts and service features (including the latest announcements in 2020). And then gradually ramping up and cover a wide array of topics such as API security, testing strategies, CI/CD, secret management, and operational best practices for monitoring and troubleshooting.

If you enrol now you can also get 15% OFF with the promo code “yanprs15”.

Check out my new podcast Real-World Serverless where I talk with engineers who are building amazing things with serverless technologies and discuss the real-world use cases and challenges they face. If you’re interested in what people are actually doing with serverless and what it’s really like to be working with serverless day-to-day, then this is the podcast for you.

Check out my new course, Learn you some Lambda best practice for great good! In this course, you will learn best practices for working with AWS Lambda in terms of performance, cost, security, scalability, resilience and observability. We will also cover latest features from re:Invent 2019 such as Provisioned Concurrency and Lambda Destinations. Enrol now and start learning!

Check out my video course, Complete Guide to AWS Step Functions. In this course, we’ll cover everything you need to know to use AWS Step Functions service effectively. There is something for everyone from beginners to more advanced users looking for design patterns and best practices. Enrol now and start learning!
