AI concepts developers should know:

1. RAG (Retrieval-Augmented Generation)
↳ Retrieves relevant external data to ground model responses.

2. MCP (Model Context Protocol)
↳ A standard for connecting models to external tools, data, and context.

3. Model Routing
↳ Dynamically selecting the best model for a given task.

4. Embeddings
↳ Turning data into vectors so models can search and compare meaning.

5. Context Windows
↳ The amount of information a model can process at once.

6. Evals
↳ Measuring the quality, reliability, and behavior of AI systems.

7. Multi-Agent Systems
↳ Multiple agents collaborating to solve complex tasks.

8. A2A (Agent-to-Agent)
↳ How agents communicate and coordinate with each other.

9. Memory & State Management
↳ Persisting and retrieving context across interactions.

Understanding these concepts is one thing. Seeing them work together is where it clicks.

Oracle has a great guide that walks you through building a scalable multi-agent RAG system → https://t.co/icEylLlR45

Their free DeepLearning course on building memory-aware agents also puts these concepts into action: https://t.co/DBrwzmvStK

What else should be on the list?

Database Scaling Summary

[Nikki Siapno @NikkiSiapno]

Kafka is often described as a message queue.

It’s not...

Kafka is a distributed commit log that lets you replay, scale, and process data streams in parallel.

That difference matters.

Here’s the mental model:
↳ Producers write events to a 𝘁𝗼𝗽𝗶𝗰
↳ Topics are split into 𝗽𝗮𝗿𝘁𝗶𝘁𝗶𝗼𝗻𝘀
↳ 𝗕𝗿𝗼𝗸𝗲𝗿𝘀 replicate partitions for durability
↳ 𝗖𝗼𝗻𝘀𝘂𝗺𝗲𝗿𝘀 read at their own pace using 𝗼𝗳𝗳𝘀𝗲𝘁𝘀

The key idea:

Kafka doesn’t just move messages, it 𝗽𝗲𝗿𝘀𝗶𝘀𝘁𝘀 𝗼𝗿𝗱𝗲𝗿𝗲𝗱 𝗲𝘃𝗲𝗻𝘁 𝘀𝘁𝗿𝗲𝗮𝗺𝘀.

That’s why it works for:
→ Event-driven systems
→ Real-time analytics
→ Log aggregation
→ Data lake ingestion

Here’s a simple decision rule:

If you need:
• Replayable history
• Horizontal scalability
• Parallel consumption
• Durable event storage

➟ Kafka fits.

If you just need:
• Simple async jobs
• Low operational overhead
• Basic task queues

➟ It’s probably overkill.

Kafka is powerful.
But it earns its complexity.

What else would you add?

"Why does YouTube never crash even when millions are watching videos at the same time?"
"How does Google find answers so fast?"
"Why does my online game not lag even when thousands are playing?"

If you've ever struggled to explain these to someone new in tech, you're not alone. System Design can feel like a complex puzzle - until you break it down into simple, relatable ideas.

That’s exactly what this post does!

From Load Balancing (spreading work like distributing pizzas to multiple chefs 🍕) to Database Sharding (cutting a giant cake into smaller slices 🎂), these 20 key concepts make System Design feel less intimidating and more like everyday logic.

Want to understand fault tolerance, caching, and microservices in a way that even a kid could grasp? Going through this visual breakdown might just change how you see backend systems forever! 🚀
