In this talk we will talk about the design decisions behind YADT and how it helps reduce the complexity of your datacenter infrastructrure while at the same time enabling you to fully automate almost all of it.

YADT - an Augmented Deployment Tool is a next generation data center deployment and system management tool. It consists of two central components: Firstly, a central management of dependencies between services, systems and software packages, and secondly a deployment based on packages for both software and configuration management. YADT is developed at and used by ImmobilienScout24 as an Open Source project.

The software makes it easy to deploy your software, configuration and operating system updates. It also provides a service-oriented abstraction layer which makes dependencies explicit and comprehensible.

YADT will update packages and restart the services in the correct order within your data center. It understands the traditional dependencies between packages as well as dependencies between services, even over the network.
