🍃 Have you ever wondered how systems talk to each other? Modern architectures rely on different integration patterns to stay scalable and resilient. Today, I’ll explain the top 9 system integrations step by step — no complications 👇 🔹 1️⃣ Peer-to-Peer 🔗 Services communicate directly with each other. ✅ Simple connections ✅ Each service knows about the others 💬 Example: Order and payment services talking to each other without intermediaries. 🔹 2️⃣ API Gateway 🌐 A single entry point that routes requests to the right services. ✅ Handles authentication, rate limiting, routing, and protocol translation ✅ Decouples clients from backend services 💡 Think of it as a smart receptionist for your APIs. 🔹 3️⃣ Pub-Sub (Publish-Subscribe) 📬 Publishers send messages to a topic, and subscribers listen to them. ✅ Loose coupling between producers and consumers ✅ Scalable and event-driven 💬 Example: Sending notifications to multiple services when an event happens. 🔹 4️⃣ Request-Response ⚡ The classic synchronous pattern: ✅ Client sends an HTTP request ✅ Server returns an HTTP response 💬 Example: Fetching user details via REST API. 🔹 5️⃣ Event Sourcing 📝 Captures every state change as an event instead of just the latest state. ✅ Full history of changes ✅ Enables rebuilding state anytime 💡 Example: Tracking all actions in an order lifecycle.* 🔹 6️⃣ ETL (Extract, Transform, Load) 📊 Move and process data between systems: ✅ Extract from sources ✅ Transform into a usable format ✅ Load into target systems 💬 Example: Aggregating data from multiple databases into a data warehouse. 🔹 7️⃣ Batching 📦 Collects multiple inputs to process them together in bulk. ✅ Reduces overhead ✅ Improves efficiency for repetitive tasks 💬 Example: Processing thousands of transactions in one batch.* 🔹 8️⃣ Streaming Processing 🚀 Processes data in real time as it arrives. ✅ Low latency ✅ Supports continuous data flows 💡 Example: Monitoring live sensor data or user activity streams.* 🔹 9️⃣ Orchestration 🎯 Central orchestrator coordinates workflows among services. ✅ Defines execution order ✅ Manages dependencies 💬 Example: Running a multi-step order fulfillment process automatically. 🎯 Why learn about system integrations? ✅ Build scalable architectures ✅ Improve resilience and flexibility ✅ Enable real-time processing ✅ Make your systems easier to maintain and evolve 🙋♂️ Which integration patterns do you use most often?
