Introduced multiplexing, allowing multiple requests over a single TCP connection.

Backend engineering is the backbone of modern software. It powers the logic, databases, and servers that keep applications running. If you are looking for a comprehensive breakdown or a guide, this article covers everything you need to build scalable, reliable systems. What is Backend Engineering? fundamentals of backend engineering free download upd

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

Learn Docker to containerize your code and deploy your first application to a cloud provider like AWS, GCP, or DigitalOcean.

: Learn version control to collaborate with other developers effectively.

As data grows, queries slow down. Backend engineers use to create pointers that help the database find data without scanning every row. For massive datasets, sharding and partitioning split databases across multiple machines to distribute the load. 3. Architecture Patterns: Designing for Scale | Nucamp Article | | The Foundations of

The role of proxies in microservices for forwarding and managing client requests. The Journey of a Request:

Every backend engineer must understand how data travels across the internet. Network protocols are the rules that govern this communication. HTTP/HTTPS

Load balancers distribute incoming network traffic across a cluster of servers. This prevents any single server from becoming a bottleneck. Algorithms like Round Robin, Least Connections, or IP Hash determine how traffic is routed to ensure high availability and fault tolerance. Concurrency and Multithreading

: Storing frequently accessed data in temporary storage (like Redis) to reduce database load and speed up response times. 3. System Architecture

How the backend talks to the frontend and other services.
