Companies running virtual desktop infrastructures (VDI) are well aware of the problems posed by even the slightest bottleneck. One user uses a bit more bandwidth than expected and, suddenly, every employee sees greater latency when trying to load a mission-critical application. VDI systems with end-user facing components can have even more troublesome side effects for a company that relies on customer satisfaction (hint: most companies). Typically, there’s a failsafe in place for companies in the form of overprovisioning that will ostensibly solve these problems. There’s more bandwidth, Host, CPU and storage overhead than necessary, so there shouldn’t be issues even if more resources than normal get consumed. It’s not that simple, though. VDIs are profoundly complex platforms, and they’re sensitive to even the smallest delay in performance. Overprovisioning doesn’t prevent these problems, and it’s a prohibitively expensive practice for companies managing countless users, both on-premise and remote.
With such latency-sensitive machines in place, IT administrators at companies using VDI need an end-to-end view into the performance of their VDI infrastructures. Companies whose employees rely on VDI to provide customer service understand the challenges even more substantially when they’re stuck waiting for their systems to respond in order to answer a customer need. It’s not enough for applications to just work. They need to work more or less perfectly and quickly for businesses to operate smoothly. When VDI administrators focus only on promoting availability, they can be blind to issues of performance.
Latency is a sign things have already gone wrong
When users start experiencing delays, it’s already too late for IT administrators to find a quick fix. Moreover, all of that money invested in the overprovisioned infrastructure seems like a waste, especially for the C-level executive making cost optimization a top priority. The issue stems from the sole focus on availability. It’s not just a financial consideration either. Technology must be in place to help teams proactively identify and solve problems with critical workloads before users, whether they’re employees or customers, notice. Administrators and other IT leaders need to be able to rely on infrastructure performance management platforms for benchmarks to assess when performance isn’t where it needs to be. Equipping IT teams managing VDIs with performance monitoring tools as robust as the infrastructures they manage is the only way to ensure latency delays and other problems never reach the end user.
Putting performance benchmarks in place gives IT administrators a clear understanding of when problems either have or will soon arise. Those benchmarks also take care of many of the same issues related to availability with which IT is often concerned. Availability is rightfully important for those managing VDI. However, understanding appropriate performance levels – and leveraging platforms and practices that promote them – can knock out both availability and performance troubles at once.
