Eric Bednash and Chuck Mills, RackTop’s Senior Technologist & an end user expert discuss the complexities of VDI.
In this installment of IT Matters, our resident end user computing expert and Senior Technologist, Chuck Mills explains what we mean when we refer to “application delivery within a VDI environment.”
In a VDI environment you want to deliver a thinner image and to be able to deliver the applications that the user needs instantaneous to those desktops. And one of the advantages to VDI is that a lot of users share the same desktop image – when we do that it is not ideal to ideal ALL of the apps in there.
Chuck recommends that you follow the three Is:
Choose what applications need to be INCLUDED in the images (utility applications).
Consider what applications need to be INTRODUCED after the image is delivered. What do we need to add on to that image in groupings by department, individual users, etc.?
ISOLATED is the third I. It is for applications that don’t always install well – perhaps due to compatibility between operating systems or when you need to run two versions of the same application.
Have you wondered if it is more complex to deal with apps in a VDI environment than it is within a traditional desktop? Chuck’s believes that it is a different and a better approach. This is because as an image is loaded up with applications that it will have a performance impact to the image, to the VDI, and also to the performance experienced by the user. So when it’s possible to individually break out applications in order to deliver them on demand to users and groups that need them – the breaking out action also allows for individual updating of applications without always needing to return to your image to update the applications. So while it takes a bit more planning you are left with a more easily maintainable environment of applications which is not embedded or ingrained into the image itself.
Strategy is essential to application delivery. Well-thought out plans and maintainability are essential to success. Some applications roll out new updates on a frequent and sometimes a weekly basis – there are ways to make this process seamless for your users with effective planning and research during the discovery process.
While complex, this is one layer of planning that offers many benefits in your VDI environment. Contact us for more information about VDI and to request follow-up with Chuck.
