We are a customer and an end-user. I was in a different company before working with SD-WAN before. This is a new company for me. We don't have live customers yet. If you're going to start using it, it's best to pick up a feature at a time and follow the documentation carefully. Try to configure it yourself and understand what's happening exactly. It's just a lot of hands-on work that really helps to understand what is going on with Versa with the CPE. That's how I learned that solution. I'd rate the solution eight out of ten.

We're a Versa partner. I don't recall which version we are using. I'd rate the solution nine out of ten. I would recommend a field test to new users. Don't just look at the paper. Try to experience it in the live network. Most of the time, that could really make a difference. If customers would like to know about it, the better way is to have a proof of concept or live demo in their network running for a certain period, with their network running on top of this SD-WAN as that's what really actually makes the difference. They could see the improvement firsthand. They could see that the bandwidth is increased. Or find out if it really could replace the MPLS with the internet. Those are the things that on paper, sometimes we could not really feel or know.

My advice is that a person come with data that meets his needs, which would provide hima good basis for selecting the correct sizing. I rate Versa FlexVNF as an eight-and-a-half out of ten, owing to the issues concerning the size of the box configurations and licensing. But, this rating also reflects the flexibility of choice afforded by the solution, as well as its futuristic approach that allows one to upgrade it to the next level of technology. It is very close to the next level of technology and one can actually upgrade his solution anytime over the cloud and to the central processor without the need to visit the field. That's simplicity.

I would advise others to just go through all the documentation for its implementation. Versa has a huge repository for documentation. It is not that tough. Just go step by step, and you will be able to do it. If you miss one or two steps, it can get quite difficult to troubleshoot and implement it. That's why I advise following Versa documentation step by step. I would rate Versa FlexVNF a nine out of ten.

We always propose only Versa solutions in our quotes for our customers when we have a new project. I only recommend Versa. VeloCloud was the first one to market and for customers that is very important. Customers ask me for a comparison between VeloCloud and Versa since VeloCloud was the first one on the market and he wants to be sure that if he goes with Versa it will not be a mistake. For me it's not enough just to be first on the market. I know Versa, but I know it's not enough. VeloCloud solutions are more public for companies and buyers than Versa is. These are the only two products that we validate that are in the regular network - Advantec and them. On a scale of 1-10, where one is the worst and 10 is the best, I would rate Versa Flex an 8. It is not a ten because it has a lot of features on the equipment and it is really heavy on the portal. It's not really friendly. Maybe they could do something different for users or administrators to have a friendlier portal.

We're just a customer. We aren't a consultant or reseller.We have a couple of different models. We have the smaller models and the medium-sized models, however, I'm unsure of the exact model numbers. New users should be aware of sizing. Making sure that the size is correct is important. There are small, medium, and large units, however, the smaller units only support certain functionality. In saying that, they seem to have some issues with some of the functionality on the small units not working. It's best to get a medium-sized unit to get some of the next-generation firewall stuff. I'd rate the solution eight out of ten.

We have a lifetime implementation. We're using the latest version of the solution. It's a good product for high-end and large enterprises, but smaller enterprises might not be a good fit. I'd just advise that especially surrounding the initial setup, a new company needs to ensure they have the right support in place. Companies need to make sure their SLA's are very clear so they can get the support they need from the outset and into the future. Compare companies and be clear about the requirements and you will have an easier time. I'd rate the solution eight out of ten. I'd give it full marks, however, I do believe that they can continue to improve on the existing product in various ways.

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.

We're telecom operators and customers. We don't have a special relationship with the company and we aren't partners. I would recommend the solution. I would also recommend that people have some specialists deploy and maintain it to make it easy to use. I'd rate the solution eight out of ten.

Hi @MarkDaniel, Versa Flex VNF (vFlex) is now VOS.  VOS is Versa Network's usp and is used as,  1. Virtual SD-WAN license which is priced as per Bandwidth tiers  for Site to site VPN connection for SD-WAN Intranet traffic. To deliver on-premise site to site connection, it needs license configuration on white boxes like Versa branded CSG SD-WAN devices (Versa is not manufacturer), Lanner, Dell, Silicon etc. 2. It is configured remotely through Versa Director (single pane of glass management). Through VD, SD-WAN Policies and features are also pushed. 3. VD work as Management, Orchestrator and control plane, and White boxes with vFlex(VOS) configured in it is Data plane. 4. VOS also works with Versa SW EP client VSAC (Versa Secure Access Client) to deliver SSL-VPN and SASE (SWG, FWaaS, etc.) - a solution for remote users without any dependency on HW or whiteboxes). SASE is not a replacement of SD-WAN edge device and mostly concentrated on cloud-hosted application access securely. ( It is still not matured solution to deliver  current enterprise IT infra requirements) Hope this helps.  Anyone who has a better understanding is welcome to add and correct me wherever required.

VeloCloud or Viptela: these two are considered to be the top two contenders in this dominant new technical WAN solution. in 2017 Cisco purchased Viptela, and VMware purchased VeloCloud. This industry is consolidating quickly. How are they different: Viptela is now Cisco SD-WAN and is a pure play SD-WAN solution, VeloCloud is now VMware NSX SD-WAN, also a pure play SD-WAN solution, and is considered by many to be the number one SD-WAN solution in the world today both in sales and in technical features. Viptela is being integrated into Cisco solutions this year, and will be included into Cisco edge router platforms over time. Eventually Cisco Security will be added to Viptela to some point. VeloCloud is now part of NSX and provides a very strong Cloud Gateway centric approach to SD-WAN, which is not only forward thinking but considered to be a unique advantage for VeloCloud. Summary: SD-WAN is now shifting to be an Application to End User software defined technical race, extending software defined benefits from the application all of the way to the users machine. VMware has a head start and technical lead, and provides a continuous solution that extends into Multiple Cloud, Data Centers and SDN based application hosting solutions. Cisco is a step or two behind VMware, will need to extend ACI to include Multiple Cloud solutions eventually in order to compete with VMware NSX SD-WAN. This work is yet to be completed. End to End software defined benefits is where VMware is demonstrating their advantage and lead today. Cisco is working hard to catch up to this model.
