9. Architecture Decisions Records
9.1. ADR-001: Login decision
9.1.1. Context and Problem Statement
We need to choose an authentication method for user login in our new application. The method should ensure security, ease of use, and scalability while providing a seamless user experience.
9.1.2. Considered Options
-
Option 1: Traditional Username and Password Authentication
-
Option 2: OAuth 2.0 with Social Login
-
Option 3: Single Sign-On (SSO) with SAML
9.1.3. Decision Outcome
We have decided to implement OAuth 2.0 with Social Login.
Rationale:
-
Security: OAuth 2.0 is a widely adopted and secure protocol for authorization.
-
User Convenience: Social login allows users to log in with existing accounts (e.g., Google, Facebook), reducing friction and improving user experience.
-
Scalability: OAuth 2.0 can handle a large number of users and integrates well with third-party identity providers.
-
Reduced Maintenance: Leveraging third-party identity providers reduces the burden of managing user credentials and security.
-
Adoption and Integration: Many users prefer using their social accounts for quick access, and many modern applications support OAuth 2.0, making it easier to integrate with other services.
9.2. ADR-002: Technology selection
9.2.1. Context and Problem Statement
We need to choose a technology stack for developing our new web application. The application requires a robust backend, an interactive frontend, and seamless integration with third-party services.
9.2.2. Considered Options
-
Option 1: Node.js with Express, React.js, PostgreSQL, AWS
-
Option 2: Python with Django, Angular, MySQL, Google Cloud Platform
-
Option 3: Ruby on Rails, Vue.js, MongoDB, Microsoft Azure
9.2.3. Decision Outcome
We have decided to use the following technology stack:
-
Backend: Node.js with Express framework
-
Frontend: React.js
-
Database: PostgreSQL
-
Hosting: AWS (using services such as EC2, S3, and RDS)
Rationale:
-
Node.js and Express: Chosen for their performance, scalability, and large ecosystem.
-
React.js: Selected for its component-based architecture, ease of use, and strong community support.
-
PostgreSQL: Preferred for its robustness, ACID compliance, and advanced querying capabilities.
-
AWS: Offers a reliable and scalable cloud infrastructure with a range of services that meet our needs.
