Citrix Summit Tech Series – Smart Deployments


It has been two month’s since I attended Citrix Summit and the amount of cloud conversations that we are having with our customers has rocketed. The majority of which are hybrid cloud / multi cloud conversations; or customers that have started the journey and are now looking to increase performance or management. 

Citrix Cloud is really resonating with our customers – both large and small. I will pen a blog specifically on this subject later in the month, but today I want to touch on two features of the Citrix portfolio and show how they are enabling our customers to make the transition to cloud hosted desktop and application delivery.

The first element of the Citrix solution that I wanted to cover is Smart Scale. Smart Scale is a component of the Smart Tools set that comes as part of Citrix Cloud. It allows the Citrix administrators to intelligently control the power state of the virtual desktop estate based on the required usage.

Let’s consider it in the context of a 500 concurrent user deployment for a typical 9am – 5:30pm company in the UK who wants to move to Azure. Without Smart Scale (or a lot of static manual work) they would need to pay Azure costs for 500 virtual machines for the full 744 hours a month, on the presumption the month has 31 days. Now think about how many hours are those desktops actually providing user services? Consider 2am in the morning, or perhaps on a Saturday afternoon whilst the match is on…! Using Smart Scale we can power down (and therefore not pay for) desktops that are not in use, and power them back on as needed to meet demand.

 Let’s talk through the math…
No Smart Scale:
500 virtual machines x 744 hours per month = 372,000 hours of cost per month
With Smart Scale:
The requirement is only 136,200 hours of cost per month!
That is with 10% of the desktops on 24×7 (37,200 hours) and 90% of desktops on 10 hours a working day with assumed 22 days per month average (99,000 hours)

As you can see, the power of Smart Scale to save costs – over 60% – when hosting desktops in the cloud is a very powerful enabler.

Now let’s couple this with the second element of the Citrix Portfolio that I wanted to talk about – Citrix Workspace Environment Management or WEM (yes another acronym sorry!) WEM is based on a late 2016 acquisition from Citrix of a company called NorSkale. 

I will write a review on WEM as whole at some point, however for now I wanted to focus on one key area – resource optimisation. WEM provides the ability to reduce RAM and CPU usage within a virtualised desktop environment by up to 70%. If we consider this reduction again in terms of costs when hosting desktops in the cloud (or on premise) we can get more users on that Azure instance type and further reduce costs.

If we combine these two technologies with the rest of the Citrix portfolio then we can start to significantly reduce costs and help our customers make that move to the cloud a reality, while maintaining end user performance and business security at the same time.

Want to hear more about this, Citrix Cloud and all the announcements from Summit? Come to one of our free update events – run by Cetus & Citrix SE’s, where you can network with peers and see how Citrix are delivering on Cloud, Security and User Mobility in 2017.
