Thoughts
- 🔒 Security: Redis provides authentication and access control mechanisms to secure your data
- ⚙️ Configuration: Tune Redis for optimal performance with options like
maxmemory-policy,appendonly, anddatabases - 📈 Monitoring: Keep track of Redis’ health using built-in metrics or third-party tools like Redis Commander
