Some clients resist switching to new technology and they're also afraid of problems with compatibility and the layout of the NOC. The NOC must change because nowadays new things are happening, but I believe that the beauty of SD-WAN is the vEdge. So for the customers that are afraid of new technologies, we can install the vEdge without spending a lot of money. It's just a virtual machine over there. You can do it on Cisco CSR or even ISR.
So we deploy a new branch or similar branch with this technology and show them. Then they're not afraid of it. It's very easy. Now, vManage is coming. So we have the analytics team, we have all the GUI interfaces so you can create a policy and now deploy it anywhere or you can define it. I believe everything is very easy for the people who want to work with it.
Technologies are not new. Just the name changes. VPN is the same as VRF, which is the same as Tenant, but the way they're playing with this technology is very different. The method of management is different. I believe that if I show clients what is happening with vManage— the interface, the analytics how you can integrate with them—they will be in love with that. Mostly what I have done is to define and elaborate for them the differences between two solutions, and point out the advantages like visibility and easy management. In the end, but they agree to move to SD-WAN
But I believe that most of the customers are still afraid of SD-WAN because they rely on old solutions. And the old solution was great and working for many years, so they are afraid of the new solution. With vEdge, we have a great way to attract them to make them feel comfortable upgrading everything into the Cisco SD-WAN.
The best feature is SD-WAN's automation capabilities. I believe many customers don't care whether we use VPN, or that use color or mGRE. When you're talking about management of, for example, a DMVPN solution or MDI solution, what is the option? So we have to go to a bug-by-bug report, like for example, NSRP to show these things. With vManage, we can see everything. We have a graph that we can click on and it helps us to remember better.
Another good feature in the HCI is the integration of a health monitoring system. Other solutions like SDx are all the same. They have an integrated health monitoring system. So if you are deploying a data center, the options aren't really that great. But this integrated health system in HCI in vManage or even SD-WAN in the vManage is helping a lot. And also
Customizing SD-WAN is very easy because you can define two colors. You can define two different operators. You can deploy a partial mesh, a full mesh, or hub-and-spoke totally differently. If you want to do this on a DMVPN solution, that's really hard. Also, things like Quality of Service in mGRE environment, in my opinion, are very hard because when you are dealing with mGRE, you have one tunnel at the hub and a different tunnel at the spoke. So what if I want to limit the traffic in my hub at the spoke? Because I have one tunnel, all the branches will be affected if I implement a limitation or restriction. So that's why we have advanced technology, like adaptive quality of service. With SD-WAN, the QoS is much easier because it is separate from the VPN.
The very beauty of SD-WAN is the separation of the plane. Right now, there are different planes. Compared to other solutions, the whole thing is totally changed. Rebound and vManage came into play as well as the new protocols like PnP. I started to convert most of the solutions from regular DMVPN into SD-WAN because we have the capability to define our VPN or define our color and customize by making a full or partial image.
In the next release, Cisco should focus on simplifying the configuration of SD-WAN. SD-WAN has a lot of room to grow. If you compare vEdge and something like Cisco CSR, you'll see the difference. Because vEdge is natively from Viptela, it is a little more complicated to set up an SD-WAN compared with an ISE device like CSR or ISR, or ISR 4000. You have now two different configuration spaces like iOS, and then some commands and styles are Viptela. So this is the thing that Cisco should work on.
I've spent a lot of time on it. I started with version 17 when SD-WAN first came out. I continued using the product after Cisco acquired Viptela because I really love Cisco. I followed everything Cisco-related since I was 18 or 19. I got my CCNP in 2003 and my first CCA in 2011. So I spend all my time on Cisco systems. Right now, I have more than 32 certificates. I recently passed the CISSP. I also have more than 20 certificates that have expired, like Cisco Sales Expert, Cisco ASA, VPN, and several old things.
SD-WAN is 100 percent stable. If you use the suggested operating system, all the Cisco solutions are stable. According to the Gartner Magic Quadrant rating, I believe Cisco was No. 1 three years ago. Now it is No. 2 or 3, so I believe that they could improve more.
And many customers have used DMVPN or VPN solutions for many years, so those solutions are also extremely stable.
it is very easy to deploy the whole solution. I have a customer with VoIP and data. For most of the data, the hub and spoke are enough, but for IP telephony or collaboration like chatting or video conference, they need to have a connection between spokes —between branches together — but not for data. With SD-WAN it's very easy.
I think vEdge is much easier to work with when you compare it to Cisco CSR. Most of the people I know prefer to use ZTP or Zero Touch Provisioning, but it depends on the type of customer. With some customers, ZTP maybe is not the best solution. They should know what's going on. And if you try to configure SD-WAN on a solution like ISR 4000 or CSR, and you compare the same thing on vEdge, you will see that the vEdge is very straightforward. I believe in CSR and ISR 4000. There are some glitches. It's possible that you will get a little bit confused, but you have followed the instruction. You have to do it very carefully. Then you make the connection vManage and everything is done.
I would rate Cisco SD-WAN seven out of 10.
