What is our primary use case?
LG Uplus is using Citrix for internal groupware. Every employee here uses Citrix to access the VDI to make some Word documents or PowerPoint presentations. We are not allowed to use our local PC resources at all.
The second use for my team's project is that we are reviewing the potential for a virtualization solution for our customers, who are mainly video editors. We offer them a low-price alternative. Instead of buying our high-end desktops or workstations, they can save money by virtualizing some application solutions.
This is deployed in LG CNS, which is a subsidiary of the LG group. Most LF subsidiary companies are a part of the LG CNS solution. LG CNS solution is combined with Citrix, which means that if you work with LG CNS, you have no choice but to use Citrix.
How has it helped my organization?
First, since we adopted the Citrix VDI, we are no longer dealing with the problem of leaking the customer's personal information. Second, we aren't investing a lot of money in buying new personal laptops. With the VDI, we aren't relying on a high-core CPU or memory in each employee's laptop. Because the functions that require a lot of memory and CPU are happening in the cloud, we can just give the employee a basic Pentium CPU laptop.
What is most valuable?
The Virtual Desktop Interface is very important because we have many departments for customer service. For example, we have operational storage and also we have a customer call center. Most of the customers are calling about a security problem.
Before we adopted a VDI storage solution, our customers' personal information was leaked. This happened a lot. But since we adopted a VDI solution, these kinds of issues have happened rarely. Of course, we banned each user from installing or sharing software, like peer-to-peer sharing software. There is no chance that a single user could leak personal information by mistake through unauthorized access.
Virtualized solutions are very important. Because of the high-speed internet service here, I think the virtualization application solution can be adopted in a B2C market for customer service.
What needs improvement?
We've tested a lot of cases with the Citrix solution and found that it's okay when the Citrix virtualized solution is adopted over the laptop or desktop. But it has some latency issues—a lag between the input device and screen—when we test it with a smartphone or tablet. The reason that users use the virtualized desktop is they want to access a Windows 10 application, but they need their keyboard and mouse. Every employee complains about the performance or quality of their VDI. After we adopted the security solution, I think the performance is quite better. But employees are still complaining about the speed of the VDI.
Latency is also a major problem when adopting Citrix for video editing software or 3D editing software, especially editing 4K video or large file size. The Citrix virtualized solution becomes too slow, so we cannot use the VDI. For the streaming, Citrix needs to improve its screen resolution problems because this is a market trend. We produce and use a lot of high-density videos. If Citrix cannot improve these kinds of issues, then we might not be able to use VDI anymore two or three years from now.
Citrix doesn't offer any solutions for the virtualization of macOS, either. I think we could use that kind of service.
For how long have I used the solution?
It's been around 10 years or so.
How are customer service and technical support?
I would rate it very low actually. Because here in Korea, most of them are for sales, not technical assistance. For developing some applications, we have to choose or test virtualized applications. But call up Citrix agencies—sales agencies—they say they cannot solve the technical issues. We have to find some technical references through the internet or through developers who have some experience with Citrix.
Which solution did I use previously and why did I switch?
Internally, the IT department uses Citrix. For developing customer service for my team's product, I use Hyper-V's client solution instead of Citrix, because the price of the Citrix virtualized application solution is too high. Citrix only provides the B2B license here, so they don't have any B2C license. I use Hyper-V-based applications and virtualized solutions because of the price issues.
How was the initial setup?
I think it was very complex. It was difficult to install Citrix by ourselves, but we have an IT department and a PC maintenance department. The initial setup required around three people. But after the initial deployment, most employees don't have any trouble with installing Citrix solutions. For each user, it takes around half an hour. For example, I broke my laptop and had to get a new laptop. I personally asked the IT and PC maintenance departments to install the systems again. It took them around 30 minutes.
What about the implementation team?
We have a dedicated IT department. They have a contract with Citrix and they're employed here.
What was our ROI?
It's tough to say whether we've really seen any cost savings. Many people don't believe the Citrix solution lowered the total cost of the whole system. But I think if we adopt an application virtualizing service, then we can reduce costs a little bit more.
Currently, everyone here is using the same public cloud server resources for every software. but if we adopt a virtualized application solution, then the IT department can choose which software needs a lot of resources and which can adopt lower-tier public cloud resources. That way, we can save a lot of infrastructure costs.
It's my understanding that the solution license fee for each user is around $300 US. If we buy a personal laptop for each employee every five years, then the total cost is five times $300 US, or $1,500 USD. So we could buy 100 personal laptops instead of the Citrix solution. If we compare the cost of a high-performance laptop and the price of the Citrix solution, the total cost savings is very small. But we can improve the security issue.
Which other solutions did I evaluate?
I think the speed and latency of Hyper-V are quite good, but one thing I worry about is the security issues. Our internally developed client for the Hyper-V solution doesn't have as many security solutions as Citrix does. As I recall, LG CNS has its own VDI solution. At this moment, there are some solutions that can replace Citrix, like FreeVDI, an open-source VDI, for example. We have tried using those kinds of service solutions in some departments, but they didn't quite meet our expectations.
What other advice do I have?
I would rate Citrix seven out of 10.
Which deployment model are you using for this solution?
