The solution is scalable. You can have as many servers as you want to run as a deployment. I'd rate the scalability nine out of ten. We use CEPH storage that is extremely scalable and can go up to petabytes, although we don't have a use case for that sizing. 

We likely do not have plans to increase usage. Our basic needs are covered.

We can add multiple hosts. Currently, we have three physical hosts with 30-40 virtual machines running. If there is a requirement change, we can easily add more rules or expand the cluster without any issues.

In terms of expanding the dimensions of your virtual disks, KVM is not easy to scale. Let's say you have a 10 GB disk, and you want to scale it up to 15 GB, the process requires that you enter a basic console and use the command-line interface to set the new size. It's not always an easy process for beginners. On the other hand, it is easy enough to scale other resources such as the CPU and RAM.

However, in general, when it comes to supporting a large number of users, it is scalable enough for us as we have thousands of users in the whole company using the services that are being virtualized with KVM.

Additionally, it's not hard to scale when talking about labor and maintenance. For example, I'm the only one administrating the infrastructure, by setting up and managing the VMs (e.g. adding VMs, editing configurations, etc.), for all these thousands of users in all different positions of the company.

I would rate the scalability of KVM as a six out of ten. In our small to medium-sized enterprise, we cater to various clients, including larger companies with over 500 employees and sometimes even up to 1,000 employees.

This solution is scalable. Ubuntu is the best version to scale because with the MAS you can set load balancing, and they offer a free account to manage the load balancing for up to ten servers.

Currently, I am the only user.

I'm not sure if the solution can scale well or how easy it can scale as right now I'm having trouble figuring out how to do it correctly. It seems like it is a bit of a confusing process.

Basically, I'm a freelance contractor. Therefore, it's just me using the solution at this time.

The scalability of KVM is not as good as that of VMware. 

We have approximately twenty people who are using this solution.

Scaling the solution is easy. You just have to add more hardware.

KVM is scalable, but it requires a certain amount of technical knowledge to understand how it can scale to other locations.

This solution is limited in terms of scalability. I think that it is suitable for a mid-range company, but for a larger company, it is not quick. It does not have features for companies that need expandable solutions.

This solution is not used directly by the end-users. If KVM is installed in their data center then they just use the virtual machine. Users don't care about infrastructure, they're just looking for stability and use the operating system for their service. It is the administrators who use this product. Typically, there are two or three administrators in each data center. In terms of end-users, I have seen more than one hundred concurrent users.

I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product. It scales really well.

The scalability of the product is really high because of architecture. Since KVM is part of a Linux kernel, it gets a lot of the benefits of its location. It has a nice strategy of memory virtualization, which is also part of the kernel. Kernel location makes possible schemes of a vhost that boosts device performance.

We currently have 300 users of KVM, with about two people as support staff. We do plan to increase usage in the future. So, we will be scaling up in the future.
