QuantRocket Architectural Overview

QuantRocket runs as a suite of Docker containers which can be deployed on your home trading computer or in the cloud provider of your choice.

Docker containers are lightweight, standalone pieces of software that include all the code and dependencies needed to run. Because they are self-contained, a key benefit of Docker containers is that they can run anywhere: under Linux, Mac, or Windows, in the cloud or on your laptop. If you've ever struggled to install code libraries on your computer, you'll appreciate Docker.

QuantRocket consists of numerous Docker containers working in tandem. Each container is a miniature app whose job is to do one thing and do it well. This design pattern is known as a "microservices" pattern and it promotes highly flexible applications.

QuantRocket containers or "services" and their functions are shown below:
