I’m currently working as a Network Engineer and aiming to enhance my expertise in cloud networking by pursuing the Google Professional Cloud Network Engineer Certification. While going through the concepts, I’ve encountered some challenges in fully understanding a few core components of Google Cloud networking. Specifically, I’m facing confusion in areas like:
Hybrid connectivity: VPN vs Interconnect and when to use which
VPC Peering vs Shared VPC: Architectural use cases and limitations
Cloud Router and Cloud NAT: When and how they work together
Firewall rules and traffic flow: Especially in complex or hybrid environments
Load balancing options: Global vs regional, TCP/UDP vs HTTP(S), etc.
I’ve read the documentation and tried some labs, but still feel I need clearer explanations or real-world examples to connect the dots. If anyone has deeper insights, good resources, or even brief explanations for these topics, I’d be grateful for the help. Your input could really make a difference.
