# Hybrid Cloud Networking

> Configure secure, high-performance connectivity between on-premises infrastructure and cloud…

Designs secure, high-performance connectivity between on-premises data centers and AWS, Azure, or GCP using VPN, Direct Connect, ExpressRoute, and Interconnect. It covers hub-and-spoke and multi-cloud topologies, BGP dynamic routing, dual-tunnel failover, and split-horizon DNS so traffic flows to the right environment reliably and encrypted.

## Use cases
- Connecting an on-premises data center to a cloud provider
- Extending a private network into AWS, Azure, or GCP gradually
- Building a hub-and-spoke topology with a transit gateway and spoke VPCs
- Setting up dual-tunnel, active-active VPN with automatic BGP failover
- Resolving split-horizon DNS so internal and external clients get the right IP
- Meeting compliance with private connectivity and network segmentation

## Benefits
- Survive a tunnel outage with sub-minute automatic failover instead of a full disruption
- Add new environments without touching existing spokes via a single hub attachment
- Contain breaches and faults to one segment with three-layer network isolation
- Keep cross-premises traffic encrypted in transit with the right IPSec or MACsec choice

## What’s included
- Connectivity option comparison across AWS, Azure, and GCP (VPN, Direct Connect, ExpressRoute, Interconnect)
- Terraform snippets for VPN gateways, customer gateways, and dual-tunnel high availability
- Hub-and-spoke, multi-region, and multi-cloud topology patterns
- BGP routing and route-propagation configuration with prefix filtering
- Security baseline: private connectivity, encryption, flow logs, segmentation, PrivateLink
- Monitoring metrics and troubleshooting commands for tunnel status, packet loss, and BGP sessions

## Who it’s for
Cloud and network engineers building hybrid or multi-cloud architectures that must connect on-premises infrastructure securely and stay highly available.

## How it runs
Wiring a datacenter to the cloud starts with sizing, not tunnels. From the VPN-versus-dedicated-line decision through BGP route filtering and dual-tunnel failover, here is how the link gets built and proven.
1. Sizes the link first: bandwidth, latency tolerance and compliance decide between Site-to-Site VPN (IPSec over internet, up to 1.25 Gbps per tunnel) and dedicated lines (Direct Connect, ExpressRoute, Cloud Interconnect) for consistent low latency.
2. Lays the topology as hub-and-spoke: Transit Gateway or vWAN as the hub, production, staging and dev VPCs as spokes, so the datacenter connects once and a new environment is one route attachment, not a new mesh of links.
3. Configures BGP peering between the on-prem router and the cloud router with explicit AS numbers and route filtering, so only the prefixes that should be advertised cross the boundary; full routing table propagation is treated as a risk, not a convenience.
4. Builds high availability as dual tunnels in active-active with ECMP, so a single tunnel failure reroutes traffic via BGP in about 30 seconds without anyone paging.
5. Encrypts according to the link type: IPSec is automatic on VPN, but on dedicated connections traffic flows unencrypted by default, so MACsec is enabled or a VPN overlay is layered on top.
6. Verifies and watches: split-horizon DNS resolution checked from both sides with dig (the most common hybrid failure), then tunnel status, packet loss, latency and BGP session health monitored per tunnel.

## FAQ
### We're only on Azure with one data center. Is the multi-cloud material wasted on me?
No, single-cloud is the core scenario. The connectivity comparison covers ExpressRoute and VPN options for Azure specifically, and hub-and-spoke works fine with one provider. The multi-cloud patterns just sit ready if you add a second platform later.

### How does the dual-tunnel failover work? Couldn't I script a route change myself?
A script reacts after you notice the outage; BGP doesn't wait. Both tunnels run active with dynamic routing, so when one drops its routes are withdrawn automatically and traffic shifts in under a minute. The Terraform snippets set up the gateways and dual tunnels for you.

### Does it operate my network after setup?
No. You get design patterns, configuration templates, and monitoring metrics plus troubleshooting commands for tunnel status, packet loss, and BGP sessions. It's not a managed NOC service; day-two operations stay with your team.
