Just finished our 30-day evaluation of Versa for SD-WAN, replacing several legacy MPLS circuits. The headline is true: our monthly carrier bill dropped by 40%, but my team's administrative overhead has easily doubled. The promised "operational simplicity" seems to be a feature reserved for the sales deck.
The core issue isn't the forwarding plane—traffic flows. It's the management and visibility. The controller interface feels like three different monitoring tools bolted together, each with its own logic. For example:
* Creating a simple QoS policy for VoIP required navigating between "Templates," "Services," and "Policy Rules." The inheritance model is... opaque.
* Trying to get a consistent view of application performance across sites meant correlating data from three different dashboards. Where's the single pane of glass that was promised?
* Every minor config push triggers a cascade of sync operations. A 5-minute change on a legacy router now takes 20 minutes of "validating" and "staging."
```json
// This is a simplified version of the CLI structure just to add a custom app.
// Why is this not a simple dropdown in the GUI?
{
"application": {
"name": "INTERNAL_CRM",
"ip-protocol": "tcp",
"destination-port": "9000-9010"
},
"attach-policy": "Business-Critical",
"site-assignment": ["Site-A", "Site-B", "Site-C"] // Had to define these individually.
}
```
I've asked for the incident postmortem from their support on two occasions last week when branch tunnels dropped inexplicably. The root cause summaries were laughably generic: "network instability" and "possible latency spike." No packet captures, no detailed path analytics from their own system. If you're selling a solution with deep analytics, you should be able to tell me *why* a tunnel in a stable state decided to reconverge.
So, the financial audit looks good. The security and compliance audit? The monitoring and operational audit? That's a different story. We're now spending more time managing the management tool than we ever did on the raw network. Is this just the cost of "modernization," or did we trade one form of complexity for another, more expensive kind?
