Thibault Charbonnier presented on using Kong as an API gateway to manage APIs and microservices. He began with an overview of why an API gateway is useful both for building and running APIs. He then demonstrated Kong, including adding an API, applying a plugin, and making a request through the gateway. Finally, he discussed new features in Kong 0.10 like dynamic load balancing and the AWS Lambda plugin.
