Communications

This is a WIP, will be adding more details and diagram as I read them through.

We've known HTTP(S) for quite sometime. And now, we've newer versions and that brought up a few terminologies. I've tried to use an analogy to explain these, and here we go...

Protocol Buffers (Protobuf): The Precise Recipe

Protobuf is like a meticulously crafted recipe card:

• Compact and standardized format
• Precisely measures ingredients (data)
• Minimizes waste and maximizes efficiency
• Easily shared between different kitchens (systems)
• Allows for precise, structured data preparation

Think of each protobuf like a recipe from Tarla Dalal's cookbook.

gRPC: The Professional Catering Service

gRPC operates like a high-end catering company:

• Offers two-way, real-time communication (like a chef and client simultaneously exchanging requests)
• Provides a full-service experience with:
  • Streamlined order taking
  • Quick meal preparation
  • Simultaneous multi-course delivery
• Supports complex, interactive culinary exchanges
• Ensures high-performance, reliable service across different restaurant chains (systems)

Like a busy restaurant chains like McDonald's.

MQTT: The Global Food Delivery Network

MQTT is like a massive, intelligent food distribution platform:

• Central kitchen (broker) manages thousands of simultaneous orders
• Publishers are like restaurants preparing meals
• Subscribers are diners receiving exactly what they ordered
• Supports:
  • Lightweight message passing
  • Efficient routing of small, quick dishes
  • Perfect for IoT-like scenarios (think food delivery to remote locations)

HTTP/HTTPS: The Transportation and Safety Infrastructure

HTTP is the entire food transportation ecosystem:

• Roads, trucks, and safety protocols
• For gRPC: A multi-lane highway supporting complex, high-speed deliveries
• For MQTT: A comprehensive network connecting kitchens and diners
• Includes security checkpoints (HTTPS) to ensure food safety and authenticity

QUIC: The Express Culinary Teleportation Service

QUIC is like a revolutionary instant teleportation kitchen:

• Combines the chef (transport layer) and delivery logistics (security) in one magical system
• Instantly materializes meals from one location to another
• Reduces waiting times dramatically
• Handles interruptions gracefully (like seamlessly switching between kitchen stations)
• Provides built-in encryption, making each teleportation secure
• Allows for instant menu changes and real-time recipe updates

HTTP/3: The Next-Generation Smart Delivery Network

HTTP/3 is the cutting-edge evolution of food delivery:

• Built on the QUIC teleportation infrastructure
• Eliminates traditional traffic congestion problems
• Supports multiple simultaneous delivery routes
• Provides:
  • Faster connection establishment
  • Improved performance in unstable delivery environments
  • Enhanced security protocols
• Like a smart delivery system that can instantly reroute around kitchen construction or traffic jams

The Culinary Communication Workflow

1. Recipes (data) are precisely measured and packaged
2. Catering services (gRPC) or delivery networks (MQTT) transport the meals
3. Highways (HTTP) provide the underlying infrastructure
4. QUIC offers instant, secure teleportation
5. HTTP/3 optimizes the entire delivery ecosystem
6. Every dish (message) arrives fresh, secure, and exactly as ordered

This culinary ecosystem ensures that information is prepared, transported, and delivered with maximum efficiency and minimal waste.
