DEV319: Embracing Change without Breaking the World - a podcast by AWS

Over the last decade AWS has launched more than 90 services. Even today, we continue to innovate at a rapid pace and are adding new features and services. We see backwards compatibility not as a goal to strive for, but as a necessity to maintain our most important asset: customer trust. It's not just the service API that needs to be backwards compatible, client-side libraries need to be able to handle service changes as well. Over the years we've learned how to design API's in a way that preserves backwards compatibility, while continuing to evolve. In this session you will learn: ·       What backwards compatibility means and what forms it may take ·       What impact breaking changes may have on consumers of an API or library ·       How to design to prevent breaking changes while allowing for future enhancements Through this session, you will also pick-up concrete design patterns that you can use and anti-patterns that you can recognize so that your service API or library can continue to grow without breaking the world. Using the AWS client-side SDKs as a case study we'll look at actual code examples of specific strategies that you can employ to keep your library backwards compatible without painting yourself into a corner.
