Advanced Systems Architecture & Cloud-Native Admin
Multi-Cloud Networking
Multi-cloud networking connects workloads across AWS, Azure, GCP, and on-prem into one coherent network. The challenge is not just connectivity but consistency: routing, DNS, identity, and security policies must work the same way everywhere. Done well, it enables workload portability and resilience. Done poorly, it becomes a tangle of VPNs, peering links, and inconsistent firewall rules that nobody fully understands.
मुख्य बिंदु
- Direct connectivity options: cloud VPN, dedicated interconnects (Direct Connect, ExpressRoute, Cloud Interconnect), and cross-cloud peering.
- Overlay networks (Tailscale, Netmaker, WireGuard mesh) simplify multi-cloud connectivity but add a dependency on the overlay control plane.
- DNS must be consistent across clouds: use a single authoritative DNS (Route53, Cloud DNS, or self-hosted) with split-horizon where needed.
- Identity federation across clouds (OIDC/SAML) lets one identity provider govern access everywhere.
- Network segmentation and firewall policies must be defined once and applied consistently; drift between clouds is a common audit finding.
- Data transfer costs between clouds are significant and often overlooked in multi-cloud designs.
- Latency between clouds varies by region pair; measure before placing chatty services across providers.
- Consider whether multi-cloud is necessary: many estates are better served by one primary cloud plus a disaster-recovery secondary.
अक्सर पूछे जाने वाले प्रश्न
Is multi-cloud worth it?
For resilience and vendor leverage, sometimes. For most estates, one primary cloud plus a DR secondary is simpler and cheaper.
VPN or dedicated interconnect?
VPN for low-traffic and non-critical paths; dedicated interconnect for high-throughput or latency-sensitive traffic.
How do I manage firewall rules across clouds?
Define policies in code (Terraform, Pulumi) and apply consistently. Avoid console-clicked rules that drift between environments.
What about data egress costs?
They are often the largest hidden cost. Design to minimize cross-cloud data movement and cache aggressively at the edge.
