Legacy Software and Immutable Infrastructure with Chad Fowler

Joy Clark talks with Chad Fowler about legacy software and immutable infrastructure. They begin by discussing legacy software and why the description 'legacy' shouldn't actually be a bad thing. Then they contrast how reusable libraries differ from a system of services which is flexible and can change over time. Chad then describes how they developed Wunderlist using a microservices architecture and answers questions about how to practically develop and test such a system and how to decrease coupling between components. They wrap up by discussing how the principles of immutable infrastructure can be applied to software development in general.
