Versa FlexVNF Review

Can easily be scanned or installed in a virtual environment and has good stability


What is our primary use case?

It's a purely internet-based solution. That means the customer already has their Ownned up-link(s), which we call DIA(Direct Internet Access). That means the customer brings their own connections to set up the virtual SD-WAN network and just use our white-box solution. On top of it, we set out an SD-WAN appliance which can be controlled by the setup on the CTG side.

How has it helped my organization?

Versa FlexVNF helps customer uses existing infrastructure to quickly complete the SD-WAN deployment through software appliance. Except for the edge hardware equipment used in customer case(s), SD-WAN provider no need invested in any hardware inside, but completely uses the existing Cloud platform.

What is most valuable?

Versa FlexVNF supports multi-tenancy, which is very important for ISP's TCO in running a SD-WAN network. Meanwhile,Versa FlexVNF is purely software based solution that help CSP(cloud service provider) upsell SD-WAN business.

What needs improvement?

We need to think about how to leverage the MPLS-VPN customers, so to integrate the SD-WAN network. We are thinking about how to make customers consolidate the loads to an SD-WAN network so that the customers can have a bigger chunk from the SD-WAN plane.Under the trend of Digital Transformation, enterprise customers looking for lower price with border bandwidth. In the designed direction,customers can have critical data be transferred by MPLS-VPN network while non-critical data or some labeled traffic can be transferred by the SD-WAN network. Considering the uncertainty of the economic situation, perhaps more companies will seek to expand data pipe based on the original network instead of building a new network. For new business areas which requires more flexible contract term,and shorter provision time, SD-WAN integrated with MPLS-VPN would be a important direction.

For how long have I used the solution?

I have been using Versa since 2017. 

What do I think about the stability of the solution?

The stability has been quite good. It's a purely software-based solution, so it can easily be scanned or installed in a virtual environment. It's very adaptive to those environments.

What do I think about the scalability of the solution?

Good and stable

How are customer service and technical support?

It is generally stable but when we have trouble with deploying or configuration we encounter certain issues. Their support is helpful and they respond in a timely manner. 

What's my experience with pricing, setup cost, and licensing?

The price is consist of several aspects but it makes sense for the market.

For the SD-WAN solution, it's not just the pricing for accreditations from the solution side. We need to combine the hardware and the connections, even managing service ourselves. Customers need to have a integrated solution from a skilled engineer team, but not just to judge if the solution providers are fair or not. But generally, when we compare with other brands, I think this solution is lean and agile.

What other advice do I have?

I would rate it an eight out of ten. There's no brand that can rank a 10. A ten from my perspective, means good enough to ramp-up. Eight is the highest that can be scored amongst the choices of SD-WAN brands. I think the SD-WAN products Versa has have great space to improve. For example, automation. We are saying it's an SD-WAN solution, but it's not fully automatic for the service provider side. It requires a skilled managed service team to handle service delivery, even senior technical team involved.Their expertise is very important in customer solutions deploy and operation.

It takes a lot of manpower to go to market which is why I'm not fully satisfied. Also, currently, we have to treat the solution as an isolated direction to go with. If the customer has invested a lot in their network, like Cisco, Huawei, or even Juniper, the customer needs to abandon their current invest. In that case, we hope that Versa will allow the customer to leverage their current and past investments.

Which deployment model are you using for this solution?

Hybrid Cloud
