Unlike HTTP's request-response model, WebSockets provide full-duplex, persistent communication channels over a single TCP connection, ideal for real-time apps. 2. Web Servers and Reverse Proxies

The tech world moves fast, but these free resources are built to move with it.

Continuous Integration and Continuous Deployment (CI/CD) automate the testing and deployment of your code. Tools like GitHub Actions, GitLab CI, or Jenkins automatically run your test suites and deploy code to cloud providers (AWS, GCP, Azure) the moment you push an update.

Looking for resources on the Fundamentals of Backend Engineering

The heart of any backend system is its data. Choosing the right database is one of the most critical decisions an engineer makes. You must weigh the pros and cons of Relational Databases (RDBMS) like PostgreSQL or MySQL against Non-Relational (NoSQL) options like MongoDB or Cassandra. Understanding normalization, indexing, and ACID properties (Atomicity, Consistency, Isolation, Durability) is fundamental. A poorly designed schema can lead to performance bottlenecks that are incredibly difficult to fix once a system is in production. API Design and Communication Protocols Choosing the right database is one of the

Backend engineering refers to the process of designing, building, and maintaining the server-side components of a software application. This includes the database, server, and application logic that work together to provide a seamless user experience. The primary focus of backend engineering is to ensure that the application is scalable, secure, and performs well under various loads.

Prevent SQL Injection (SQLi) and Cross-Site Scripting (XSS) by validating and cleaning all incoming user data.

Caching reduces database load and speeds up application response times by storing copies of data in temporary, high-speed storage. Client-Side vs. Server-Side Caching If you share with third parties

Keeping cached data accurate to the source database is notoriously difficult. Common patterns include:

This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.

Structured Query Language (SQL) databases like PostgreSQL and MySQL store data in predefined tables with relationships. They are built on ACID compliance (Atomicity, Consistency, Isolation, Durability), making them the industry standard for financial systems and applications requiring strict data integrity. Non-Relational Databases (NoSQL)

Always encrypt sensitive data at rest (in the database) and in transit (using HTTPS/TLS).
