Course Highlights

  • Cost Optimization

    Are you worried about getting a big AWS bill? We have an extensive section on cost optimization techniques. You should get a firm grasp on how to keep your AWS cost in check, even if you're new to AWS and serverless.

  • Cold Starts

    You have been using Lambda for a while, but are you still not sure how cold starts REALLY work? In the performance section, you will learn techniques that actually work, and when to use Provisioned Concurrency.

  • Relevant in 2020

    Serverless is evolving rapidly, best practices and patterns are still emerging. You will learn about the latest features, tools and techniques and how to get the most out of your serverless application!

Meet Yan Cui, your instructor

AWS Serverless Hero

Hi, my name is Yan Cui. I'm an AWS Serverless Hero and the instructor of this course. I'm also the author of Production-Ready Serverless by Manning and a regular speaker at user groups and conferences internally.

I am an experienced engineer and have run production workload on AWS for 10 years. I have been an architect and principal engineer with a variety of industries ranging from banking, e-commerce, sports streaming to mobile gaming. I have worked extensively with AWS Lambda in production and have been helping clients around the world adopt AWS and serverless as an independent consultant.


  • I'm already using Lambda in production, what will I learn from this course?

    I work with a lot of clients who are already running Lambda in production, but they still make poor decisions in their serverless architecture. The thing is, the Lambda platform is evolving rapidly and many are following out-dated advice that doesn’t take into account new service features and tools that are now available to them. With this course, you will learn timely advice based on the latest developments in the platform and the wider ecosystem.

  • I don't have a lot of time to learn, is this course for me?

    This course is designed with busy developers like you in mind. It's structured as a collection of bite-sized lessons so that you can easily drop in and out, and extract the most learning with the minimum time commitment.

  • How does this related to Production-Ready Serverless?

    It touches on overlapping areas such as observability, but covers newer features, tools and techniques (such as Provisioned Concurrency) that weren't available when I made Production-Ready Serverless. It also covers additional areas such as cost optimization and multi-region resilience which were outside the scope of Production-Ready Serverless. At the same time, there are plenty of topics that are covered in Production-Ready Serverless that I will not cover in this course, such as project organization, testing, etc. Whereas Production-Ready Serverless gives you a hands-on project to follow along and build something from scratch, this course gives you many small, independent lessons (a mix of theory and demos).
