Cookies or JWTs? 🚀👇

Full article: https://lnkd.in/eBwZvUTX


⚠️ Challenges
- 📈 Scalability: Traditional session storage limits scaling.
- 🔄 Stateful vs. Stateless: Tying sessions to instances creates load imbalance.
- 🔗 Service Communication: Session validation must be efficient.
- 🛡️ Security: Poor session management leads to vulnerabilities.


🍪 Session Management Using Cookies
1️⃣ Encrypted Cookies: Store encrypted session data on the client.
2️⃣ Centralized Storage: Use Redis to manage session data.
✅ Pros:
- 🔧 Easy to implement & scale.
- ⚡ Reduces lookup overhead.
❌ Cons:
- ⚠️ Prone to hijacking & XSS if insecure.
- 🌍 Cross-origin concerns.
- 📦 Increased data transfer costs.


🏷️ Session Management Using JWTs
🔹 Stateless: No server-side storage.
🔹 Sent in requests (Authorization header).
✅ Pros:
- 📌 Scalable & independent.
- 🔒 Secure (if well-implemented).
❌ Cons:
- 🚫 Hard to revoke.
- 📏 Large token size.


🏆 Best Practices
✅ Secure Cookies (HttpOnly, Secure, SameSite).
✅ Short-lived JWTs + Refresh Tokens.
✅ Centralized Identity Provider (OAuth, OpenID).
✅ Rate Limiting & Monitoring.
✅ Encrypt & Sign Tokens.


💡 Conclusion: Choose cookies, JWTs, or both based on security & scalability needs. What’s your approach? 🚀
