As we approached contract renewal with this customer, something interesting happened.
Instead of focusing purely on pricing — they paused and asked a bigger question: “If we’re renewing anyway… should we also modernize?”
That single question changed the direction of the conversation.
Where We Started
Their environment was stable and well-designed.
They were running Zscaler workloads:
- ZIA Virtual Service Edge (VSE)
- ZPA Private Service Edge (PSE)
All hosted on customer-owned VM hardware, supported by physical switches and CPE devices.
It worked. But it was also tied to:
- Hardware lifecycle management
- Capacity ceilings
- Refresh cycles
- CAPEX planning
- Operational overhead
In other words — stable, but not agile.
The Shift in Mindset
Instead of renewing the same setup, we asked:“What if we keep the architecture… but remove the hardware burden?”
So we migrated the entire Zscaler workload into CBC Private Cloud in Beijing — without changing their Zero Trust design.
No redesign.
No disruption.
Just modernization underneath.
What Changed
- Physical switches and CPE eliminated
- Fully virtualized infrastructure
- Dual eNet Cloud Routers (ECR) deployed for redundancy
- Scalable VM resources for VSE, PSE, and App Connectors
The infrastructure became software-defined, elastic, and cloud-native.
What Stayed Exactly the Same
- ZIA & ZPA reference architecture
- CBC Tech’s congestion-free IP backbone & Internet gateways
- Security posture
- User experience
From the users’ perspective — nothing changed.
From the infrastructure perspective — everything did.
The Business Impact
- Reduced hardware dependency
- Improved scalability and agility
- Simplified operations
- Predictable OPEX instead of hardware CAPEX
- A future-ready platform for expansion
Most importantly, the customer now has room to grow — without waiting for the next hardware refresh cycle.
A Reflection
Contract renewal is often treated as a commercial exercise.
But sometimes, renewal is the perfect moment to step back and ask: “If we were building this today — would we build it the same way?”
In this case, the answer was no.
So we renewed smarter.
And modernized while we renewed.
And that made all the difference.
