Cloud Networking, LB, CDN

Learn cloud network basics with scalable delivery using load balancing and CDN edge architecture.

Expert Level

Connect networking with cloud scale: VPC design, load balancing, and CDN acceleration.

Click the numbered markers on each diagram to explore the concept step by step.

Why This Matters

Cloud networking decisions define latency, uptime, and security at scale.

Confusion Busters

Common confusion: CDN and load balancer same

Fix: CDN caches at edge; load balancer distributes dynamic backend traffic.

Common confusion: Private subnet means isolated from all

Fix: Private subnet blocks direct internet ingress but still routes via controlled gateways.

Cloud Networking Basics

  • ▸VPC/VNet segmentation with public and private subnet tiers.
  • ▸Route tables and security groups govern access paths.

Load Balancing and CDN

  • ▸Load balancers spread traffic and support health-based failover.
  • ▸CDN edge caching lowers latency and protects origin services.
