Group 10: Networking & Content Delivery

Network infrastructure and content delivery: VPC (private networks), Cloud Load Balancing (traffic distribution), Cloud CDN (content caching), Cloud DNS (domain resolution), VPN (secure connections), Interconnect (dedicated connectivity), Network Intelligence (monitoring & troubleshooting). Design for performance, security, and global reach.

Network Architecture Layers: VPC for isolation; Load Balancing for high availability; CDN for performance; DNS for resolution; VPN/Interconnect for hybrid connectivity; Network Intelligence for observability. Consider latency, bandwidth, and security requirements.

Services & Network Layers

Virtual Private Cloud (VPC)

Layer: Network foundation and isolation.

Best for: Resource isolation, security boundaries, multi-tier architectures.

Features: Subnets, firewall rules, routes, peering, shared VPC.

Cloud Load Balancing

Layer: Traffic distribution and availability.

Best for: High availability, auto-scaling, global traffic management.

Features: HTTP(S), TCP/UDP, internal/external, health checks.

Cloud CDN

Layer: Content caching and acceleration.

Best for: Static content delivery, global performance, bandwidth optimization.

Features: Edge caching, cache invalidation, signed URLs, compression.

Cloud DNS

Layer: Domain name resolution.

Best for: Reliable DNS, private zones, DNSSEC, global anycast.

Features: Authoritative DNS, private DNS, DNSSEC, health checks.

Cloud VPN

Layer: Secure connectivity.

Best for: Site-to-site connections, remote access, hybrid cloud.

Features: IPsec tunnels, high availability, dynamic routing.

Cloud Interconnect

Layer: Dedicated connectivity.

Best for: High bandwidth, low latency, predictable performance.

Features: Dedicated/partner interconnect, VLAN attachments, SLA.

Network Intelligence Center

Layer: Network observability and troubleshooting.

Best for: Performance monitoring, connectivity testing, topology visualization.

Features: Performance dashboard, connectivity tests, network topology.

Interpretation Guidelines

VPC > 7.0: Essential for any multi-resource deployment, security boundaries, and hybrid architectures.
Load Balancing > 7.0: Critical for production applications requiring high availability and auto-scaling.
CDN > 7.0: Must-have for global applications serving static content or media.
DNS > 7.0: Recommended for custom domains, private DNS zones, and reliable resolution.
VPN > 7.0: Ideal for hybrid cloud connections and secure remote access.
Interconnect > 7.0: Choose for high-bandwidth, low-latency dedicated connections.
Network Intelligence > 7.0: Valuable for complex networks requiring monitoring and troubleshooting.

Anti-Patterns

Single VM deployments: Don't over-engineer networking for simple, isolated workloads.
CDN for dynamic content: Use load balancing instead for personalized or frequently changing content.
VPN for high-bandwidth transfers: Consider Interconnect for consistent, large-scale data movement.
Complex DNS for simple apps: Use default DNS for applications without custom domain requirements.
