Zi Seng Yeo (“Jason”. @jasonyzs88) is the 14th VCDX to join Nutanix. Jason is part of the Global Services Organization in Singapore. Prior to starting at Nutanix, Jason spent the last 5 years at VMware where he served as a delivery consultant and, more recently, as an End User Computing Specialist in the VMware APJ Centre of Excellence.
“Jason is one of seven VCDX-DT (Desktop Technology) worldwide,” said Bill Hussain, Sr. Director Consulting Services for Nutanix. “Hiring him was a huge coup as he is a true cornerstone-type resource for consulting in APJ. While he will be focused primarily on consulting delivery and partner enablement in region, we would be remiss to not leverage his thought leadership more broadly worldwide.”
Jason says that one of the biggest challenges to a successful VDI deployment is that organizations simply try to convert convoluted traditional physical desktop deployments to virtual. He puts an emphasis on helping customers get their desktop environments cleaned up and streamlined for VDI.
“Another issue with VDI for larger organizations,” Jason says, is that they often have teams such as virtualization, storage and desktop who are used to working in silos. For VDI to be successful, it is essential that these teams come together and work collaboratively to enable an efficient deployment.”
This is one of the reasons why Jason likes hyperconverged technologies – because the platform itself helps eliminate the challenges of IT silos by eliminating the requirement for separate storage administration. Segregating VDI traffic to the top-of-rack-switch also minimizes network traffic and contention.
“Hyperconvergence, and especially Nutanix helps by taking away complexity of design and virtualization and storage layers,” Jason said. “There is less to worry about: less people, less change requests, etc.”
Jason maintains that hyperconvergence also helps eliminate politics of the datacenter. “The desktop team no longer has to pester the central storage IT administrators for more LUNs or IOPs. VDI is a new technology for many storage administrators, and they often don’t understand virtual desktop variables such as high write requirements.”
Prior to joining Nutanix, Jason set up a couple of parallel VDI deployments: One using VMware VSAN and one using Nutanix. “It was interesting to see how things happened at both sites in parallel,” Jason said. “I was amazed at how much easier it was to deploy VDI on Nutanix. The metrics were also great.”
The Nutanix technology was one of the compelling reasons Jason decided to join the company. “Separating the CVM from the kernel helps with upgrades and changes because they are decoupled from the hypervisor,” Jason explained. “There are simply too many dependencies to worry about if everything is in the kernel.”
While Jason will continue to assist with VDI deployments at Nutanix, he will be involved with all aspects of Acropolis and Prism implementations. He also says that he is definitely going for his NPX certification. He is not sure which two hypervisors he will focus on yet, but will likely choose vSphere and Acropolis.
I asked Jason if he ever utilized ROI analyses as part of his VDI implementations. He said that he didn’t utilize financial modeling specifically, but that he always does try to understand the business requirements that customers are trying to achieve. He keeps these objectives in mind while architecting the design and during the deployment.
