Ada has a modular, lightweight, layered architecture, centered around Scala stack, with a strong focus on performance. Scala is a modern functional and object-oriented JVM language developed by academics at EPFL.
The main libraries include Play Framework for web, Spark for distributed computing and machine learning, and Akka for streaming. Ada persists data in two popular NoSQL databases, Elastic Search and Mongo, which provide flexible, schema-free JSON storage. As a matter of fact, JSON in Ada is prominently used coast-to-coast.
Ada is packed and compiled using Play sbt scripts as a standalone application with an embedded Netty server, which can be deployed anywhere.
