In this talk, we’ll briefly explore the history of traditional testing approaches such as manual, unit, functional and integration tests before introducing the missing piece in the testing puzzle, chaos engineering where we move beyond focusing on our code, to look at the infrastructure running our systems.

We’ll talk about the history of chaos engineering, look at how Netflix pioneered this engineering approach, before looking at Amazon’s Fault Injection Service (FIS) and how it can be used to test different components. Finally we’ll look at the recent announcement of functionality allowing us to test Lambda functions, before moving onto a live demonstration of how we can carry out these tests with Lambda and how FIS works.

I’ve been working with Serverless systems for nearly 10 years, and have been involved in projects that have had a traditional bias to testing, before looking at FIS over the last year, initially with EC2 before moving onto testing serverless components, both for internal projects and for my employers clients.

I recently ran a workshop on FIS, delivered in person and online so have proven experience in this area.

Last year was my first year of professional speaking, where I presented at Serverless Days Milan, a number of AWS Community Days and User Groups, along with the SREDays conference in London.
