Why edge computing and VDI make the perfect pair

On the flip side, for those who were exposed to it, the backend 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. 

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?

Streamlined IT teams

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 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. 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 datacentre 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 minimised risk of downtime, while making the IT team look focused, responsive, and streamlined. 

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. 

Safer and more agile

Running on a hyperconverged edge computing solution, the VDI deployment can provide improved workforce agility at an affordable cost. Employees can log-on securely to any machine on the network and gain access to their files, emails and applications—they’re not just limited to PC terminals, but can load their personal desktop or applications on their mobile device or tablet.

Running a VDI deployment in this way also offers a cost-effective and secure method to extend network access beyond the office walls and provide remote access to employees wherever they are. Plus, the IT team can receive automated alerts that flag potentially suspicious activity or log users out of an account that has been inactive for a pre-agreed time.

Generic sign-ins are often used across organisations as a speedy way for employees to access multiple machines, but they do pose potentially huge security problems. Whether it is doctors accessing patient records or retailers handling sensitive financial data, in both cases, companies are legally responsible for protecting end-user data. Failure to do so risks reputational damage and even prosecution. 

VDI, in an edge environment, is able to deal with these potential issues by making it quick and easy for employees to log in across multiple machines with their own Active Directory credentials. This technology also offers multi-factor authentication to guard against unauthorised access, ensuring businesses stay compliant with consumer data protection laws such as HIPAA, GDPR, and PCI.   

BYOD becomes cost effective to manage too, and no longer an issue that raises operational and security concerns. An employee’s personal mobile device, laptop or tablet can be integrated onto an officially-sanctioned VDI environment. This takes it from a potential security risk, to a secure, authorised, and monitored network device where information is protected from accidental disclosure and loss. 

The future of VDI 

While VDI always had the potential to realise improved workforce agility and centralised network management, IT analysts and industry experts stated for some time that VDI adoption has been relatively slow. This is where it was previously hindered by high cost, complicated software licensing and weak network connections. Now, with the advent of hyperconverged edge computing, and the accompanying reductions in cost and complexity, businesses of all sizes are able to benefit from this technology. 

It is now easy for IT teams and end-users to adopt VDI, thanks to additional functionality, improvements to network response times, and massive simplification of system management. The ability to create offsite backups at remote locations or in the cloud has delivered an extra layer of IT resilience and protection, while automation and centralisation capabilities now take care of the most important, but time-consuming, heavy-lifting. Because of edge computing and HCI, it is no surprise that VDI has spiked in popularity, and this growth is predicted to continue in the future.
