VPCs, load balancing, firewalls, VPNs, DNS, TLS, API gateways, observability, and zero-trust — the full network stack across AWS, Azure, GCP, and DigitalOcean.
Networking is where cloud architectures break. This course teaches you to design secure, observable, and resilient networks across all four major clouds. You will plan CIDR ranges, deploy multi-tier VPCs, configure global load balancers, implement DDoS protection, build cross-cloud private connectivity, manage certificates, and enforce zero-trust at the edge. Every module ends with a project that proves the design works.

Design and deploy a zero-trust network across two clouds (AWS + GCP). Use mutual TLS for service-to-service traffic, private endpoints for all data services (no public IPs), policy-enforced egress to the internet, and an identity-aware proxy as the only ingress for admin access. Document the threat model, the policy decisions, and prove isolation with a red-team exercise (e.g., attempt SSH to a private instance from outside the VPC and demonstrate the failure).
I'm considering 'Cloud Networking & Security' — a course on the full networking stack across AWS, Azure, GCP, and DigitalOcean. Covers: networking fundamentals refresher (OSI/CIDR/TCP/DNS/TLS), VPC design, load balancing, firewalls and DDoS, VPNs and private connectivity, DNS and service discovery, TLS certificate management, API gateways, network observability, and zero-trust security. 10 modules × 10 tasks each. Context: 1. My current role: [e.g. "backend dev", "junior SRE", "platform engineer", "security engineer"] 2. Cloud experience: [e.g. "AWS only", "AWS+GCP", "single-cloud, multi-cloud is new", "multi-cloud at scale"] 3. My goal: [e.g. "design a multi-cloud network for a startup", "pass the AWS Advanced Networking specialty", "implement zero-trust at my company", "harden an existing VPC after a security audit"]
Simulate a multi-VPC outage caused by overlapping CIDR ranges or a misconfigured route table. Document the diagnosis flow, the rollback procedure, and the preventive policy (Terraform constraint, organization-level guardrail) that would have stopped it. Test the runbook against a real (test) account.
Design and deploy a PrivateLink-based architecture exposing a managed service to a consumer VPC across accounts without ever traversing the public internet. Include DNS routing, IAM trust policies, the endpoint service config, and a load test verifying private-only egress.
Implement a Transit Gateway connecting 8+ VPCs across 2 regions with route-table-based isolation between dev/staging/prod. Include propagation rules, BGP advertisement testing with a simulated on-prem connection, and a cost analysis comparing TGW vs full-mesh peering.
Audit network egress costs for a real (or representative) cloud workload over 30 days. Identify the top three egress hotspots, implement at least two optimizations (CDN, VPC endpoints, region co-location), measure the cost delta, and write a one-page memo for engineering leadership.
