THE EDGE irtual Desktop Infrastructure (VDI) has peaked and troughed in popularity since it came into existence in 2006. But it is a technology reaching new heights of growth in recent years, with predictions stating that the global VDI market will be worth close to US$5 billion by the year 2020. V The concept of VDI was simple and excellent: if we virtualise desktops we can reduce hardware spend, cut the three-year refresh cycle, simplify desktop management and ultimately save businesses time and money. It all seemed straight-forward and, at a glance, the technology looked elegant – especially for the desktop user that wasn’t exposed to the back-end infrastructure. On the other hand, for those who were exposed to it, the back-end infrastructure was bulky, complicated and costly. VDI software went hand-in-hand with hefty licensing fees and lock-in to vendor hardware, both of which pushed up adoption prices. Because of this, VDI adoption stayed limited to large enterprises for a long time. for specialist skills when just a couple of hours of training is typically all you need. Once the virtual desktops have been rolled out, software and anti-virus updates for each user can be remotely managed and maintained. The centralisation and automation of various time-consuming day-to-day tasks help IT teams deal with emergencies better, should they arise. Some Edge Computing systems also provide in-built, automated disaster recovery capabilities, including replication, snapshot scheduling and file-level recovery that assist in the retrieval of lost files from individual virtual desktops. They can also protect the entire network with self-healing machine intelligence. This centralisation and resilience means that IT teams can create a consistent disaster recovery plan that runs in the background, without individual users having to take any action. Ultimately, this ensures there is no longer a need to rely on employees to update their own anti-virus software or schedule backups of their own data. Simplifying and streamlining www.intelligentdatacentres.com For even more redundancy, full network backups and snapshots of individual desktop profiles can also be sent over the wider network to either a remote data centre or a cloud repository. Working in a VDI environment also allows a user to simply move to a different machine and log back in, in the event of a terminal or other network access point failure and, in most cases, this means their profile and data remain undamaged as both reside on the Edge Computing unit. Plus, a replacement machine can be quickly configured without any need to perform time-consuming data recovery. This ensures they have an IT infrastructure with much higher availability and reduced risk of downtime, while making the IT team seem focused, responsive and streamlined. But, in the past few years, Edge Computing and hyperconvergence have disrupted the VDI market. These technologies have made deployment opportunities available to more businesses. So, it seems that Edge Computing and VDI have emerged as a perfect pair, but how? Rolling out VDI is simple and practical when utilising Edge Computing hyperconvergence solutions, even for lean IT teams that look after hundreds of users. There is no longer a requirement RUNNING ON A HYPERCONVERGED EDGE COMPUTING SOLUTION, THE VDI DEPLOYMENT CAN PROVIDE IMPROVED WORKFORCE AGILITY AT AN AFFORDABLE COST. Alan Conboy, Office of the CTO at Scale Computing Another advantage of running VDI in an Edge environment is that data can be stored close to the point of creation and access. This reduces dependence on remote centralised servers or distributed local servers and solves the problem of slow connectivity, latency and bottlenecks that have arisen on legacy deployments running over a WAN or VPN.
