- Map on-prem networking to AWS, Azure, and GCP constructs
- Design CIDR plans and tiered VPC/VNet segmentation
- Deploy hybrid VPN, private access, DNS, and load balancing
CAPSTONE: Global Secure Multi-Cloud
Regulated enterprise, 3 clouds, 2 regions: transit, cross-cloud connectivity, inspection, Zero Trust, GSLB with WAF, DR, full IaC, ADRs, threat model and an exec-level design defence
- Engineer BGP and transit (TGW, vWAN, NCC) at architect depth
- Build global delivery with GSLB, CDN, WAF, and DNS failover
- Design inspection hubs, Zero Trust access, and policy-as-code guardrails
