Networking & Communication Protocols

🌐 Networking & Communication Protocols

Master the underlying protocols and patterns that enable modern distributed systems to communicate reliably and efficiently.

🏗️ The Networking Roadmap

Phase 1: Foundations

  • Focus: HTTP/1.1, HTTP/2, and HTTP/3 (QUIC).
  • Goal: Understand the evolution of the web’s primary protocol.

Phase 2: Real-Time Communication

  • Focus: WebSockets, Server-Sent Events (SSE), and Long Polling.
  • Goal: Build full-duplex, low-latency communication channels.

Phase 3: Service-to-Service (RPC)

  • Focus: gRPC, Protocol Buffers, and REST.
  • Goal: Optimize internal microservice communication.

🛠️ Key Concepts

  • OSI Model: Understanding the 7 layers of networking.
  • TCP/UDP: Choosing between reliability and speed.
  • TLS/SSL: Securing data in transit.
  • DNS & Load Balancing: How requests find their way to your servers.
