Dropwizard is a open source Java framework for developing ops-friendly, high-performance, RESTful web services. It was developed by Yammer to power their JVM-based backend services. Dropwizard pulls together stable, mature libraries from the Java ecosystem into a simple, light-weight package that lets you focus on getting things done.
Dropwizard has out-of-the-box support for sophisticated configuration, application metrics, logging, operational tools and much more. It allows you and your team to ship a production-quality HTTP+JSON web service in the shortest time possible. This video explains the history of Dropwizard and how Yammer uses it to power more than a dozen backend services at scale.
