Motivation: The solution strategy for the Compass app is driven by the need to deliver a robust, scalable, and user-friendly application while efficiently managing development processes and using appropriate technologies. By making informed decisions based on our quality goals and constraints, we aim to create a solution that aligns with both technical requirements and user expectations. Incorporating Auth0 for authentication enhances the app's security, and utilizing GitHub Actions for CI/CD pipelines ensures efficient development workflows and reliable release management. By automating deployment to stage environments after merges into the main branch, we enhance development efficiency and deployment reliability while maintaining a robust testing environment.

1. Technology Decisions

Quality Goal	Scenario	Solution Approach	Link to Details
Performance	Extensive user activity and responsiveness	Utilizing React/Next.js for frontend development and Java Spring Boot for backend allows for efficient rendering on the client-side and lightweight, scalable microservices on the server-side.	NextJs Spring Boot
Scalability	Anticipated increase in user amount and data volume	Using Docker containers and Kubernetes orchestration to manage multiple pods (backend and frontend) in a cloud environment, enabling simple scaling and load balancing based on demand.	Docker
Maintainability	Ease of code maintenance and future updates	Embracing PostgreSQL as the database of choice for its robustness, reliability, and compatibility with both frontend and backend technologies, facilitating data management and updates.	PostgreSQL

2. Top-Level Decomposition

Quality Goal	Scenario	Solution Approach	Link to Details
Flexibility	Accommodating evolving user requirements	Implementing a microservices architecture with Spring Boot for backend services and Next.js for frontend components, simplifying independent scaling, deployment, and updates of functionalities.	-
Extensibility	Integration of third-party services	Utilizing API endpoints in Spring Boot to expose backend functionalities, allowing integration of external services, while using Next.js server-side rendering for dynamic frontend interactions.	-

3. Key Quality Goals
