Backend Engineering Fundamentals Portable

A that will get you building correct CRUD backends quickly. Supplement it with a dedicated security course and a book on message-driven architectures to fill the gaps. If you’re prepping for backend interviews, this covers ~70% of the “system design basics” you’ll need.

APIs and network protocols define how servers communicate with clients and other backend services.

The CAP theorem states a distributed system can guarantee at most two out of three properties simultaneously: backend engineering fundamentals

How do you handle 10 users vs. 10 million users?

Ideal for low-latency, internal microservice-to-microservice communication. WebSockets A that will get you building correct CRUD backends quickly

Independent deployment, technology flexibility, and isolated fault domains.

Sub-units of a process that share memory, enabling fast communication but requiring careful synchronization. Event Loops and Non-Blocking I/O APIs and network protocols define how servers communicate

TLS/HTTPS encrypts data moving between clients and servers.

Architectural patterns dictate how the components of a backend system interact, scale, and handle failures. Monolithic Architecture

JSON Web Tokens (JWT) store user session information securely in a stateless format.
