The value of correct sizing in the Cloud

The Cloud is rising and the growth predictions are insane. Often we aren’t even aware when we are making use of the Cloud. Think about Hotmail, Office 365, Citrix Cloud or even websites like Airbnb. Not owning the servers, like Airbnb does with houses, but also with their website back-end, isn’t the only advantage of the Cloud. Other advantages are obvious: scalability, flexibility, disaster recovery, etc. But those advantages come at a cost. With a pay-per-user model like Office 365, the costs are evident. But if you go to an Infrastructure-as-a-Service (IaaS) model it can become confusing. Choosing the right amount of cloud resources is crucial to get the best value for money.

Citrix Cloud on AWS

I was recently afforded the unique opportunity to collaborate on a project to test capacity out of a Citrix XenApp on AWS deployment. The goal of the project was to independently determine the maximum user density for a few different EC2 instance types running XenApp 7.14.

The reason why your SBC or VDI users prefer their laptops

The reason why your SBC or VDI users prefer their laptops

Users are becoming more resource intensive when it comes to graphically rich media and you’ve seen it with many web applications, Microsoft PowerPoint, rich-media websites built with HTML 5, and even other business critical applications like radiology applications. These are all apps you’d expect to see at some point in a modern workspace, virtual or not.

VDI Reference Architecture Monthly – December 2016

VDI Reference Architecture Monthly – December 2016

Happy new year and welcome to the first Reference Architecture Monthly of 2017. Sorry it has taken me a while to get this one out. We’ve been having fun at the end of year festivities while also preparing some really cool stuff for Login PI and Login VSI. There were two reference architectures posted in December by Dell EMC and Nutanix. While I always encourage you to grab these papers yourself and go through them thoroughly, I’ve also distilled them down to some of the cool bits that caught my attention. However, there can be much more to these papers, so please check them out if you are interested. Having our vendor community use Login VSI to show off their cool capabilities and top line performance is always a blast. So, let’s get crackin’…

Fluctuation in VDI Test Results you can solve with Login VSI

Fluctuation in VDI Test Results with Login VSI

As a test engineer at Login VSI, I perform many tests each day. But to give some scientific value to these test results, I usually repeat these tests at least 10 times to make sure that there is not a lot of variance between tests with the exact same settings. Some of our customers seem to struggle with getting consistent results in their own environment and that’s why they frequently ask me “How is it possible to get a different result when repeating a Login VSI test with the same identical settings?” In this blog, I will explain the most common reasons why this is happening and I will share some best practices on how to solve this.

VDI Reference Architecture Monthly – November 2016

VDI Reference Architecture Monthly – November 2016

Here we are again with another post for the Reference Architecture Monthly. I’m finding that there is a lot of great information with respect to proofs of claim and sizing, which is incredibly useful if you are trying to architect your own solution. In most cases these documents will carry this information, but what is more interesting is that there is almost always a unique morsel of information, sometimes hidden in the context of some great testing and analyzation. So, I’m going to start focusing on what I consider “the cool bits”.

Dell Precision Appliance for Wyse - VMware Horizon 7.0 with NVIDIA M10 Test Results

by Dell Wyse Solution Engineering

Summary

Looks like DELL has released an update to their hyper-converged Precision Appliance for Wyse to now include NVIDIA’s M10 GPU. Graphics rich experiences are becoming all the buzz lately and if you ask me, that is where I would want my desktop VM to live because the benefits for the end-users are massive. Typically, GPUs are seen as the elixir to what has been commonly referred to as a “laggy” experience, which basically expresses the feeling we have when there is time between a user action and the desktop (like clicking on the Start Menu in Windows) or seeing videos get all choppy.

VDI Performance Testing: To VSImax or not to VSImax

VDI Performance Testing: To VSImax or not to VSImax

When you are performing a VDI performance test with Login VSI, the most important part of any test are the results. But the result is only valid when you have completed a successful test, because there are many factors that can influence the test result. So how to make sure that a test was run successfully? One of the misconceptions that I hear quite often is that fact that you will need to reach VSImax for a test to be considered successful. In this blog I will explain the best way to determine if a test was successful or not.
