The scalability is limited to 200 gigabit throughput on the best version of the solution which is the 5000F series. 

We can use the solution as an HA in active/active mode which allows us to increase throughput by 50%. 

For one customer, we used the 1200F series with a 40 gigabit throughput and usage was less than 70% with one million users. 

Fortinet FortiADC is a scalable solution. More than 100 users are using the solution in our organization.

I rate FortiADC seven out of 10 for scalability.

In our company, we have three to four people who are working with Fortinet FortiADC excluding myself.

Increasing our usage is dependent on the size of our current IT infrastructure.

If we want to scale it up, we'll need more FortiADCs.

Fortinet FortiADC is easy to scale.

It is a scalable product.

With the scalability option on the cloud, you can have that easily. 

The product has good scalability.

It's scalable. We can add more ADCs to the cluster if needed.

I would rate the scalability a seven out of ten. Because if we miss the appliance's sizing in the beginning, it will be hard to scale.

Our clients are small to medium-sized businesses. We didn't deploy the big appliances.

The solution is scalable up to a point. If you're expanding your company and have a lot of customers, say 2,000, you need to go for a higher end model. Otherwise you'll have problems if you're using the hardware model. With the cloud and with the VM, you can always scale to your requirements. We have 400 users. We implement the solution and if customers want to use our website and database servers, the client traffic will hit the ADC and it will load balance to all the servers. If the company decides to expand, then we might need to scale FortiADC. 

The solution is scalable. Every virtual machine can expand easily. You must make size coding for three or five years for flexibility. FortiADC doesn’t have restrictions on the number of applications. It provides high availability and built-in security features like antivirus and sandbox integration.

The platform is very easy to scale because it's virtual. You just buy licenses and increase the hardware when needed. We have as many as 3,000 users, although not all of the time. We probably have about 1,000 concurrent users. All of them are students.

They have different appliances to cover low performance, less performance, and big-box data that supports large capacities. 

With our customers, we have 200,000 end-users.

Had no need to scale it up, so all good.

No issues with scalability.

We have a fixed integration so scalability is not relevant for us.
