Introduction

Backend development involves the server-side of applications and databases, focusing on what users don't see but what powers the user-facing side. It includes everything from APIs to databases to server logic.

Fundamentals

HTTP/HTTPS

• Definition: Protocols used for transferring data over the web.
• Key Concepts: Request methods (GET, POST, PUT, DELETE), status codes, headers, SSL/TLS encryption.

RESTful APIs

• Definition: A design pattern for building APIs to enable communication between client and server.
• Principles: Statelessness, resource representation, standard methods and status codes.

Databases

• Types: Relational (SQL) and NoSQL databases.
• Examples: MySQL, PostgreSQL, MongoDB, Redis.

Authentication & Authorization

• Definition: Processes to verify users' identity and grant access to resources.
• Techniques: JWT, OAuth, OpenID Connect, session-based authentication.

Languages & Frameworks

Node.js

• Overview: JavaScript runtime built on Chrome's V8 engine.
• Strengths: Asynchronous event-driven architecture, non-blocking I/O.

Express.js

• Overview: Minimalist web framework for Node.js.
• Key Features: Middleware support, routing, template engines.

Python & Django

• Overview: High-level Python web framework.
• Key Features: Built-in admin interface, ORM, security features.

Java & Spring Boot

• Overview: Java-based framework for building standalone applications.
• Key Features: Inversion of control, aspect-oriented programming, microservices support.

Ruby on Rails

• Overview: Server-side web application framework written in Ruby.
• Key Features: Convention over configuration, DRY principle, MVC architecture.

Microservices Architecture

• Definition: Architectural style that structures an application as a collection of loosely coupled services.
• Principles: Single Responsibility Principle, decentralized governance, scalability.

DevOps Integration

CI/CD

• Definition: Continuous Integration and Continuous Deployment practices to automate the software delivery process.
• Tools: Jenkins, GitHub Actions, GitLab CI/CD.

Containerization & Orchestration

• Definition: Containerization involves packaging applications with their dependencies; orchestration manages containers.
• Tools: Docker, Kubernetes.

Monitoring & Logging

• Importance: Essential for maintaining and troubleshooting backend systems.
• Tools: Prometheus, Grafana, ELK Stack (Elasticsearch, Logstash, Kibana).

Security Best Practices

• Key Areas: Data encryption, input validation, secure APIs, regular security audits.
• Principles: Principle of least privilege, defense in depth, security by design.
