You invest your time and effort breaking up that monolithic Frankenstein into a suite of elegant composable micro-services, you containerize them and you deploy them somewhere in the cloud in the form of distributed resources. Then you proudly watch it all come together reaping the benefits of the most scalable architectures. It is all fine and dandy from this point on. Too good to be true? Of course! This session is about what to do when you wake up to find yourself in the middle diagnosing that first bug or application failures through the convoluted web of distributed systems of your own doing. Through a series of code snippets, we will introduce the most important open-source projects tools to strike the right balance of tooling and best practices to handle failures gracefully and detect them quickly in the world of distributed systems.
