Weekly update 08

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!

Welcome Binaris as our sponsor for August!

Regular readers of this blog would have noticed that over the last few months I have collaborated with Binaris on a number of blog posts, notably around serverless migration patterns.

It’s my honour to welcome Binaris as sponsor for this bog! Here’s a short message from the good folks at Binaris to explain what they’re building and their vision for the future of FAAS.

At Binaris we envision a world where applications are built out of functions. Functions are better for developers, better for operations and better from an infrastructure viewpoint. Binaris Serverless Platform lets developers use serverless functions for their core application development. We believe that when developers Think Functions they are faster, happier and more productive.
By Think Functions, we mean developers can focus on their own application code. It means that we take care of many of the burdens that stand in the way of building a scalable cloud application. It means that developers never think about servers, never think about cost and never think about performance.
Binaris invokes functions in milliseconds. We are 20x faster than Lambda and about 2x faster than traditional microservices, so you never have to worry about cold starts and pre-warming functions or configure services to colocate in order to achieve better response times.

MEAP update for Production-Ready Serverless

We have released 2 new videos on my video course Production-Ready Serverless, this time around performance and cost optimization.

Remember, whilst the course is still in the MEAP, you can get 40% off the face price using the code ytcui. As we are approaching the final release of the course, we have started brainstorming about what topics we should cover next. I’m running a poll on Twitter over the next couple of days, let us know what you’d like me to cover next!

I have also turned this course into a classroom setting, so if you’re interested in having me run this as a workshop in your company, then drop me a line via the Contact page.

Step Functions: how to apply try-catch to a block of states. I have used AWS Step Functions a lot at DAZN and sometimes we find ourselves in a situation where I have to apply the same boilerplate code to catch errors from a number of states. Instead, you can simplify things by wrapping a block of states into a single-branched Parallel state, and apply the Catch clause just once!

AWS Announcements

The big news this week is that Aurora Serverless is now generally available. It’s an exciting announcement. But, I can’t help but to feel disappointed that Aurora Serverless is still based on persistent connections as opposed to simple HTTP request-response model like DynamoDB. It puts the burden of managing connection pooling onto my shoulder, something I would do without…

AWS IOT Defender is also generally available.

Elastic File System (EFS) now has provisioned throughput.

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!
