Network Function Virtualization (NFV) & 5G:

What Cloud Engineers Do:

1. Virtual Network Functions (VNFs)
   - Deploy virtual routers, firewalls
   - Scale automatically
   - Reduce hardware costs

2. 5G Core Network (5GC)
   - Cloud-native architecture
   - Network slicing
   - Service-based architecture

3. Cloud-Native Tools Used
   - Kubernetes (container orchestration)
   - Docker (containerization)
   - Helm (package management)
   - Istio (service mesh)

4. Benefits
   ✅ 40-60% cost reduction
   ✅ Faster deployment (hours vs weeks)
   ✅ Automatic scaling
   ✅ Improved reliability
