3. API Connectivity & Web Services

APIs (Application Programming Interfaces) enable back-end systems to communicate with other applications, front-end interfaces, or external services:

• RESTful APIs:

  • REST (Representational State Transfer) is a widely adopted architectural style that uses standard HTTP methods (GET, POST, PUT, DELETE) for interaction.

  • REST APIs are stateless, scalable, and language-agnostic, making them easy to implement and integrate.

• GraphQL:

  • A query language developed by Facebook that allows clients to request exactly the data they need, reducing over-fetching and under-fetching of data.

  • Preferred in modern applications for flexibility and performance.

• gRPC:

  • A high-performance, open-source framework by Google using Protocol Buffers (protobuf) for data serialization. Ideal for microservices and low-latency communication.

• WebSockets:

• Enables real-time, two-way communication between the client and server. Used in chat apps, live notifications, and collaborative platforms.

4. Web Servers and Runtime Environments

• Apache and Nginx: Widely used web servers that handle HTTP requests and serve static or dynamic content.

• Node.js: A server-side runtime environment that executes JavaScript, especially suited for building scalable, event-driven applications.

• Docker: Used for containerizing applications to ensure consistency across development, testing, and production environments.

5. Authentication and Security Tools

• OAuth2, JWT (JSON Web Tokens), and Session-Based Auth: Standards and protocols for secure user authentication and authorization.

• Bcrypt, Argon2: Hashing algorithms used for password encryption.

• SSL/TLS, firewalls, and rate limiting are used to protect back-end services from unauthorized access and abuse.

6. DevOps & Monitoring Tools

• CI/CD Pipelines (e.g., GitHub Actions, Jenkins): Automate deployment and testing of back-end code.

• Monitoring Tools (e.g., Prometheus, Grafana, New Relic): Track performance, detect bottlenecks, and ensure system health.

• Logging Frameworks (e.g., Logstash, Fluentd, or Winston): Collect and analyze server logs for debugging and analytics.

Together, these tools and technologies enable back-end developers to create robust, efficient, and secure server-side applications that form the backbone of modern digital experiences.
