Setting up hybrid cloud connectivity between hyperscalers like Google Cloud or AWS and your on-premises infrastructure isn’t just a technical checkbox—it’s a critical part of modern IT strategy.
But one wrong decision—like overloading your core firewall—can turn that link into a single point of failure.
In this post, we’ll share how we helped a customer build secure and redundant VPN tunnels between GCP, AWS, and their on-prem setup—without putting pressure on their network team or risking downtime.
The Hidden Risks in Hybrid Cloud Connectivity
When companies set up hybrid cloud connections, the core firewall often becomes the default anchor point. And that’s where the trouble begins.
Why using your core firewall is risky:
- 🔧 Any config changes require a maintenance window
- ⚠️ Missteps could take entire network segments offline
- 🔐 Tight security rules limit routing flexibility
- 🚨 Adds pressure to NetOps teams in the middle of incidents
If you’ve ever heard “we can’t touch that firewall without 3 approvals and a 2 a.m. window,” you already know why this model doesn’t scale.
A Smarter Approach to Hybrid Cloud Connectivity
What We Implemented
- ✅ OPNsense virtual appliances deployed on-prem to act as VPN gateway
- 🔐 Used native VPN gateway services from GCP and AWS for tighter cloud integration
- 🔄 BGP routing layered on IPsec tunnels to automate failover and dynamic path discovery
Outcome: Redundancy Without the Headache
This solution gave the customer:
- ✔️ No need to touch the core firewall—security remained intact
- 🔄 Automated failover—routes adapted without manual intervention
- 🧘 Less stress on NetOps teams—no firefighting during cloud outages
- ⚙️ Scalable hybrid cloud architecture—easy to extend to other clouds or regions
While it required more up-front effort, the result was a future-proof, zero-downtime interconnection strategy.
Why This Matters for IT Teams
Too often, hybrid connectivity is treated as a side task—patched into legacy networks instead of designed as part of the big picture.
But modern businesses need:
- Dynamic routing
- Decoupled, scalable architecture
- Tools that don’t rely on manual fixes when things break
With proper planning, hybrid cloud connectivity becomes a strength, not a liability.
