Efficient Serverless Development: Latest Patterns and Practices on AWS

Ready to dive into the world of serverless with AWS? In this talk, we're going to cut through the jargon and get straight to what serverless really means and why it's a game-changer for developers like us. We'll walk through a day in the life of a serverless developer, showing you how to write and test serverless applications using ephemeral environments and make your development process smarter using the latest tools and techniques.

Testing serverless applications is not as daunting as it sounds, and you can have a good local development and testing experience. I will show you how. And I will share advanced architectural patterns and security best practices to help you build applications that are secure, scalable and cost-efficient.

Join me for a practical journey on how to make the most of serverless on AWS and supercharge your output!

What's the focus of your work these days?

I help companies go faster for less by adopting serverless technologies.

What's the motivation for your talk at QCon London 2024?

Serverless is a very different paradigm from how we build software in the cloud, and many people are struggling with the shift in mindset and approach. Platforms like Lambda are easy to get started with but hard to master.

I have run serverless workloads in production since 2016 and have made a lot of mistakes and learned what works and what doesn't.

I want to share that knowledge with everyone who wants to work more efficiently and be more productive.

How would you describe your main persona and target audience for this session?

An experienced engineer who is working with AWS and wants to leverage AWS to build better software faster.

Is there anything specific that you'd like people to walk away with after watching your session?

Working with serverless doesn't have to be hard, but you do have to adapt your software development practices to make the most of it. This is because serverless technologies come with different constraints and opportunities than serverful technologies.

I want the audience to walk away with a good idea of how they can change the way they work with serverless technologies to make themselves more productive.
