API Used for Authentication System Design
APIs (Application Programming Interfaces) serve as the communication channels between different microservices and external components. The APIs define the rules and protocols for how different software components should interact. In the context of an authentication system, various APIs are used for seamless communication between microservices:
8.1. RESTful APIs:
RESTful APIs are commonly used for communication between microservices due to their simplicity and statelessness. Each microservice exposes a set of RESTful endpoints, allowing other services to make HTTP requests to perform specific actions.
8.2. Token-Based APIs:
For secure communication and data exchange, token-based APIs, such as JSON Web Tokens (JWT), are often employed. JWTs can be used to carry authentication information securely between microservices without the need to repeatedly verify credentials.
OpenID Connect and OAuth 2.0 are widely adopted authentication and authorization protocols. They define a set of rules for secure and standardized user authentication, allowing third-party applications to access user data without exposing sensitive credentials.
8.4. GraphQL:
GraphQL is an alternative to RESTful APIs that allows clients to request only the specific data they need. In the context of an authentication system, GraphQL can be used to efficiently query user information and manage authentication-related operations.
Designing Authentication System | System Design
Keeping your important digital information safe is like building a strong foundation, and the key to that is a good security system. This article will help you understand how to make a robust security system step by step. We’ll start with figuring out what you want to protect and what you want to achieve. Then, we’ll talk about the detailed design aspects, like how the system works at both the small and big levels, the structure of the database, using smaller specialized services, and making sure the system can handle more load without slowing down.
