—————

1️⃣ 🔗 Unified Entry Point
• 🎯 Goal: One access door for all services 🏠
• 🛠️ Stack: Spring Cloud Gateway, Zuul, Kong 🚪
• 🌐 Use Case: Mobile app hits one endpoint, routes to 10+ microservices 📲
• ❌ Problem Solved: No exposure of internal URLs 🚫🔍

⸻

2️⃣ 🚦 Smart Routing & Load Balancing
• 🎯 Goal: Dynamic traffic control 🧭
• 🛠️ Stack: Spring Cloud LoadBalancer, Eureka 🔁
• 🌐 Use Case: /orders → OrderSvc, /auth → AuthSvc 🎯
• ❌ Problem Solved: No need for clients to know who’s where 🕵️

⸻

3️⃣ 🛡️ Centralized Security
• 🎯 Goal: Validate tokens, apply auth rules 🔐
• 🛠️ Stack: Spring Security, OAuth2, JWT, Keycloak 🔑
• 🌐 Use Case: Auth checks at gateway before hitting user services 🙅‍♂️
• ❌ Problem Solved: No repeated security logic in every microservice 🧱

⸻

4️⃣ 🚫 Rate Limiting & Throttling
• 🎯 Goal: Protect services from overload 💣
• 🛠️ Stack: Bucket4j, Resilience4j, Redis ⚙️
• 🌐 Use Case: Free tier blocked after 1000 hits/day 📉
• ❌ Problem Solved: Stops abuse, keeps APIs healthy 🏥

⸻

5️⃣ 📈 Logging, Monitoring & Transformation
• 🎯 Goal: Track, trace, and transform 💡
• 🛠️ Stack: Sleuth, Zipkin, ELK, Actuator 📊
• 🌐 Use Case: Transform request format + trace ID in logs 🕵️‍♀️
