VDI Considerations


After doing the initial proofing of VDI, its worth pointing out some important stages for consideration when making the system live for use, ignoring these stages can lead to the implementation of such a project failing in its application to users.


The user experience and efficiency.

The design and delivery of the VM’s is important, try and deliver what the user expects from their desktop, not only the software, but the appearance too. This can save time on training, and dramatically reduce the onslaught of questions such as where do a find this.

There will be differences to the “way the client works”, by anticipating what those are again will provide a smooth and less stressful transfer when working with VDI.


BYOD and the end-point. VDI allows a lot of diversity in the use of devices to deliver a desktop experience to. Stand your ground and ensure that you clearly state what type of device and specification is required.( list of supported devices)

For example yes RD Web and VDI will work on an android platform, but attempting to run rdp on an 8 gb memory phone, with a 5inch screen just isn’t practical, although it may be suitable for vapps

Also ensure you know who is accessing the device, and that they are following corporate security policies and procedures. The link with domain control is essential for validating users



Capacity requirements.

Ensuring your infrastructure is adequate and can cope with a VDI deployment is essential, keeping graphics, memory requirements, storage to minimums when creating the VM helps to keep the delivery and use of VDI with user expectations.

I read the term boot storm, where a large requirement of the workload is needed at once (such as all VDI users logging in at the same time), so large that it may cause massive spike in usage can cripple a storage area network (SAN) that is not prepared for such an event. So ensuring you’re network speed and storage requirements are up to the task.

Servers with Solid-State Disk (SSD) or onboard flash cache may help prevent spikes in I/O. Monitoring I/O and controller metrics of the broker then, administrators can make decisions which will determine performance specifics for their storage system


Virtualization is the key

A solid management plan can make all the difference in the success of your VDI deployment. For example, golden images and server provisioning helps administrators quickly provision resources to VDI workloads. Similarly, hypervisor VM redundancy capabilities (how VMs failover if there is an event) allow you to create powerful high availability and resiliency policies. Remember, today’s VDI ecosystem is a lot smarter. You can now set specific alerts and monitoring thresholds to find issues before they become major problems.

That require greater levels of insight and visibility, so you’d want to deploy agent-based AV technologies. However, if you’ve got a kiosk running a locked-down VM with little user interaction, a simple agentless solution can help. Data loss prevention (DLP), intrusion prevention services (IPS) and intrusion detection services (IDS) each provide granular security controls around VDI. For example, if Social Security numbers are getting transferred within a network against protocol, these types of systems can catch it and stop it from happening.
