Technology Stack

The Federated & Distributed Data Sharing Appliance (FDSA) is built on a robust and scalable tech stack, incorporating a range of modern technologies and third-party components to ensure high performance, security, and seamless integration. 

Core Technologies 

• Docker: Utilized for containerization, allowing FDSA to deploy and manage applications in a consistent environment across multiple systems. Docker ensures the portability and scalability of the appliance. 
• Docker Compose: Facilitates the orchestration of multi-container Docker applications. Used for defining and running the multi-container FDSA services, ensuring they work together seamlessly. 
• nginx: Employed as a high-performance reverse proxy and web server, nginx handles load balancing, security, and routing within the FDSA environment. 
• Python: The core programming language used for developing FDSA's backend services and automation scripts. Python's extensive libraries and frameworks contribute to rapid development and integration. 
• Flask: A lightweight Python web framework, Flask is used for building FDSA’s RESTful APIs and web services. It allows for quick and flexible development of secure and scalable applications. 
• PostgreSQL: The primary database management system used in FDSA, PostgreSQL provides robust, scalable, and secure data storage, with support for complex queries and transactions. 
• Hasura GraphQL Engine: Integrates seamlessly with PostgreSQL to provide a powerful GraphQL API for real-time data access. Hasura automates much of the data access process, making it easier to manage and query federated data. 
• Keycloak: A comprehensive open-source identity and access management solution, Keycloak is used in FDSA for managing authentication & authorization, and 2FA.
