Traditional PCs have high acquisition and maintenance cost; this perhaps is a technology reality. Joseph Kariithi, Business Development Manager, Next Technologies says they might be affordable; but they consume more power and may not be that secure.
During a recent awareness event in Nairobi, with a team of Cisco Systems experts, Kariithi showcased how IT can deploy Virtual Desktop Infrastructure (VDI) solution with an end-to-end systems approach using Cisco VXC. He said like the PCs, traditional Virtual desktop environments are costly and complex coupled with multiple components, which act as security breath points.
Cisco VXC 6215 is a new thin client that unifies voice, video, and virtual desktop into one device.
Organizations' IT demands are growing, users are demanding tablets and mobile devices in the work environment. This environment is experiencing expensive 3 to 5 year desktop refresh cycles; Windows upgrades i.e. Windows 7 to 8 and costly ongoing maintenance. In this case, complexities have become barriers to adoption of new technologies; organizations will now need to think about how well the system contributes to the business group especially at different levels that require scalability.
Before deploying a VDI, organizations need to consider the following:
What are hard and soft costs involved with the deployment of a VDI environment? These are direct or indirect cost involved with system installation and training, as part of the upfront costs a company will have to incur. The management needs to decide whether they will start small and grow incrementally.
"The more the organization digs deeper into such issues, that's when the management realizes the process is becoming difficult, costly, complex and they get a feeling it's no longer reaching at the business needs", says Kariithi.
Simplicity entails time taken to roll out virtualized desktop environments, will the solution be complex compared to traditional VDIs which have various components for instance connection brokers. Kariithi says the IT team might not be comfortable having multiple points of failure and the management might not be able to afford training to deal with VDI for example the SaaS, and management servers.
The more complex a solution is, the greater its number of potential failure points, which decreases overall reliability; and the longer it will take to diagnose and debug any issues that arise.
Therefore organizations have to look at how simple is the virtual desktop infrastructure they want to deploy especially rolling them out in production.
Scalability and High availability
Scalability becomes of equally importance; will the solution relay on shared storage? What if the organization doesn't have shared storage, do they have built in availability or they will need to re-architect for scale to ensure redundancy.
