SD-WAN is certainly scalable. Huge companies use SD-WAN. Ever heard of Jiffy Lube? Ever heard of PNC Bank? Ever heard of Gap? (I do not know whether Gap surviving because of COVID) Those are just a couple of companies off the top of my head who are using SD-WAN solutions. It is largely scalable. I think that PNC Bank had something like 4,000 locations. It is very scalable.  

In the SD-WAN world, they have something called an orchestrator. On the orchestrator, you can see everything that is happening on your SD-WAN. So you can see if a particular carrier is going down, or if you are experiencing errors or whatever. You can see a complete picture of your entire wide area network in one pane of glass. In the old days before SD-WAN, if you had six carriers, you would have to go and look on six different carrier systems to find out what was going on. Even then, you were not necessarily getting all the information that you needed. SD-WAN is the greatest thing since sliced bread when it comes to having an overview of services.  

It is very widely adopted because it is better and cheaper and easier. You are seeing more companies looking for those solutions. Some of the telecom companies are offering SD-WAN. Some of the UCaaS (Unified Communications as a Service) companies are also promoting SD-WAN. One of the reasons that they are is to assure their clients that their telephone service will always be up.  

Cisco SD-WAN is scalable.

Our clients are large enterprises. 

I rate the scalability of Cisco SD-WAN a ten out of ten.

The solution is very scalable. 

The scalability is always handled prior to our work with customers. Keep in mind that the scalability is not very large in Portugal.

I give the scalability of the solution a nine out of ten. The solution scales out very well. We just need the right product in our data center to integrate Cisco SD-WAN. For this particular solution, Cisco SD-WAN would scale out successfully. The amount of memory required is substantial, as we have many TCP connections that require a lot of memory. We also need a lot of processing files. Initially, the solution was lacking in this area, but it has since been improved. We used the solution for twelve hundred sites, while the company I was at previously had twelve thousand. They have since migrated to Palo Alto, although I have not used it. We were unable to use it on remote sites as Palo Alto did not have a hardware version. However, Palo Alto now has a hardware version, so we can use it in a controlled environment.

The scalability is good. I would rate it as seven out of ten.

The scalability of Cisco SD-WAN is good.

Cisco SD-WAN is very scalable.

We have approximately 15 users.

This is deployed in our headquarters. We have them around the country, and we have some large offices and have the solution at all of them. There are likely 1,000 or more users on the solution all over the country.

The same generation and the same product is the easiest to scale and we have them mostly on some of our sites. We have the needed redundancy. That said, I would question the scalability if you are dealing with multiple types or other versions or other products. It needs to be of the same generation to take advantage of the path of least resistance.

We never test it with other solutions, however, with Cisco and other vendors is there is not recommended.

I rate the scalability a nine out of ten, and we have approximately 150 users from different departments. We may increase our usage depending on customer and business needs.

The solution is scalable. You can expand it as necessary.

It's a great option for enterprise-level organizations. 

We have multiple companies using the solution. They range from 500 to 1000 or so.

This solution is easy to scale. 

Cisco has multiple options: it has Meraki SD-WAN, which is a simplified version. It can be suitable for any retail or small- to medium-sized customers. For large customers, we have Viptela, which is for customers who need more control on their traffic. This solution is suitable for any type of customer. 

Seven members of the team interact with the solution.

We haven't encountered any issues with scalability when adding more branches or refining the solution.

Cisco SD-WAN is a scalable solution.

On a scale from one to ten, I would give scalability a nine.

Cisco SD-WAN has good scalability, so I'm giving its scalability an eight out of ten.

The product is pretty scalable. 

In terms of Cisco SD-WAN, we have close to 200, and that's a pretty big number. We have about 12 engineers around the clock using the solution. 

The scalability is highly efficient. When operating on-premises, scaling up involves a comprehensive analysis of the architecture and the provisioning of service resources. The scalability is directly linked to the provisioning of these resources. In terms of licensing, there is a notable benefit as Cisco now offers free licensing.

I think the scalability fits the customer requirements. The number of staff required for maintenance depends on the complexity of the network and the number of sites. A single part does not cover it, so we have about 20 staff running our network services.

The product is scalable. 

I rate the platform's scalability a ten. Currently, over 5,000 users are working with SD-WAN. As for plans, while the exact numbers are uncertain, usage is expected to grow.

It is a scalable platform. We work mostly with enterprise companies such as banking institutes. I rate the scalability an eight and a half out of ten.

I rate the solution’s scalability an eight out of ten. It's fairly scalable unless you have the regional fabric aspect of a large network. So it's fairly scalable. 

Most of our clients use this solution. We are engaged with about nine out of ten clients; we are involved in that. They fall between medium and enterprise businesses.

Cisco SD-WAN is very easy to scale.

For us, the solution scales well. We are far away from its limits. That said, we are not, let's say, a very big company.

The scalability is okay. We largely deal with medium and large enterprises in Mexico. There are typically government or educational organizations.

We don't have deployments that have more than 500 sites. That's our biggest deployment from one customer. I cannot say anything for huge deployments because we do not have a lot of metrics.

The solution has great scalability. The people using it are mostly senior management, junior management, and junior engineers. Maintenance for this solution requires about four people: two senior employees and two regular employees.

Scalability-wise, it's good, because when the customer's application load or data traffic increases, I can easily scale out the same product to match the increase.

Cisco SD-WAN is scalable. 

The scalability is great when you have a mature template for configurations.

The solution is scalable, however, it may be less so than Cisco Viptela. SortNet also has a portal that is not completely mature, and quite complex. This is why we developed a customer portal, dedicated to our customers, although some portals are still Viptela or SortNet. This custom portal has the ability to simplify the considerations of SD-WAN features for all of our sign-in customers.

We have approximately nine or ten big customers that are still in the proof of concept phase. Of those, three or four are large scale projects. Those have hundreds or even thousands of users on the network.

Cisco SD-WAN is scalable. 

It is a very scalable solution. 

The tool is scalable. My company has 20 customers for it. 

The scalability is fine. The issue has not been an issue of technology, it's been one of price. 

This solution is pretty scalable. 

This solution is very scalable - the only requirement is to add the licenses for the devices being brought on board.

The scalability of this solution has given problems in the past since it is quite new. 

It is certainly a scalable solution. For example, you could start with the 10G module and upgrade to 40G, 100G, or DWDM. It is handled on a module basis.

We probably have 400 to 500 users.

The solution seems to be scalable so far. For all the opportunities we've been involved with, it's been good and we haven't hit a wall.

The solution is scalable.

The solution is very scalable. From the branch office to the data center, you have so many Cisco modules, and you can cut the system the way you like. Any shape and size are available from Cisco. I don't see any provider of networking solutions with more options. It's definitely a solution where you can pinpoint exactly the specific needs of a branch, a data center, or an office, and find the right piece of hardware. There are so many sometimes it can be even complicated to choose, however, Cisco provides everything from the ground up without any problem. It's a tried and tested solution, and therefore is very well documented. 

Cisco SD-WAN's scalability is good.

I am pretty sure it is going to be high. At this point, it has low usage, but we will push it to the maximum of its capacity. 

I can not speak to the scalability, but we used Cisco SD-WAN for a big gas station digitalization project. The gas station had to be connected to a government-owned company and then deployed to 5,500 locations, so it was a big project. I believe a government-owned company currently completes the maintenance of the 5,500 locations.

Our company was just in charge of implementation and installation. I am unsure how many technicians they have, but the maintenance response is so slow, which may mean that the technicians are not well educated or trained about the SD-WAN. Regarding deployment, it took one person about two to three days to connect, configure and do the ATP.

The scalability of Cisco SD-WAN is good. 

We have approximately 2,000 people using the solution and approximately 25 of them are engineers.

It is very scalable.

Cisco SD-WAN is scalable.

This is a scalable solution. Our financial client has approximately 200 branches.

It is good. You can scale as much as you want, but you have a limitation of the license. 
You cannot go further than a certain number of licenses. I can only have 15 locations or so because it would scale the price.

The solution is easily scalable. A company would have no trouble expanding.

Cisco SD-WAN is scalable. It's scalable and reliable, and robust.

The scalability could be better. 

I have found the solution scalable. We have approximately 10 clients.

It is a scalable product and it can also be integrated with other Cisco products such as NSO (Network Services Orchestrator) and the virtual CPE. The customers for this product are enterprise-level companies.

This solution is super scalable. Most of our clients are midsize and enterprise-level organizations. These include banks, social security funds, educational institutions, government departments, community groups, and agencies. 

If you can get to the first step of migration and to stable operations then the scalability is not a challenge. The Cisco solution is pretty scalable. I think it's the most scalable solution in the market, but it has to setup properly. Once it's set up properly. Then scalability is not a challenge. Scalability is more of a challenge with products like Fortinet. The initial migration to SD-WAN is more of a challenge here.

Cisco SD-WAN is a scalable solution.

We have many users in our organization.

It is very scalable. We have it deployed to 23 countries, AWS, Azure, and our data centers. 

Scalability is somewhat limited, especially from the technical side. It's just a gateway with some routing and we don't use any dynamic routing. There's nothing fancy and the scalability is enough for our needs. 

We have not tested the scalability because the volume of traffic is not very high for us. We didn't have to look at it.

We have about 16 users. Because we are just evaluating, we don't have a forecast at this point.

It scales to a very high number, in terms of the hardware branch elements or hubs, or data centers, or even the cloud connection points. Scaling is not really an issue when it comes to Cisco SD-WAN. 

We currently have two customers on the solution. Right now, mostly, it's in the phase of testing to see how it fits the customer environment. They are considering growing in terms of the sizing and migrating all their traditional or legacy network to SD-WAN. 

The solution is very scalable. 

The solution is scalable.

We have medium-sized clients, largely based in the retail industry.

This solution is highly scalable. We have heard that you can have 10,000 or 20,000 servers.

Our clients are medium-scale customers, as opposed to really large enterprises. They are retail stores, organizations in the hospitality industry, and pharmaceutical companies.

I would say that the scalability is pretty limited, although we don't have any issue with it because we only use the basic features. For example, we don't use dynamic routing. We have 50 users.

The scalability of Cisco SD-WAN is great.

Scalability is a strong selling part of virtualized solutions. I hope it is the case for Viptela; something to test.

The solution is scalable. This is based on the bandwidth, how the customer makes use of the internet.

Perhaps we will increase usage in the future. 

It's scalable. We have around 250 sites around Jordan.

This is a scalable solution. There are between 1,000 and 1,500 users.

The solution is scalable.

One of my client's organizations has approximately 5,000 users using the solution.

The solution can scale. If a company needs to expand it, it should be able to do so rather easily.

We typically work with small and medium-sized organizations. I'm not sure if the companies we work with intend to expand their usage in the future or not.

The solution is quite easy to expand. We find it very scalable.

This solution can scale from SMB to the enterprise level. It is very impressive.

Scalability in this context does not concern users, but connections between the head office and branch offices. We do not deal with endpoints or end-users.

We do not have plans for expansion or increasing our usage at this point.
