  • 5. Is VDI the Answer? The need to reevaluate desktop strategies is • COMPLEXITY: The technologies needed driving many companies to consider virtual for VDI (i.e., servers, storage, networking, desktop infrastructure (VDI)—and with good thin clients, and virtualization software) are reason; VDI has promised to solve many provided by many different vendors, traditional challenges of physical desktops. causing considerable confusion among IT Because virtual desktops are centralized onto staff about which technologies to adopt. BECAUSE DATA IS virtual machines that run on corporate Once the infrastructure is built, companies NOT STORED ON datacenter servers, VDI makes day-to-day are left with vendor lock-in, which can be tasks such as deploying new desktops or detrimental in a market where technology applications, and supporting distributed changes are fast and furious.

While it is far easier to deploy virtual failed to grow in popularity. The question to desktops than physical desktops, IT must ask is: What are the barriers to VDI first have the capacity to deploy them. This adoption? becomes a notable operational barrier when companies need to scale up quickly • COST: Although VDI is noted as being less to support employees or consultants on expensive than fleets of physical time-sensitive or temporary projects. computers, companies frequently find Furthermore, due to latency issues, themselves spending much more than performance is greatest when users are originally anticipated; the up-front CAPEX located near the datacenters, an often required to start a VDI deployment is unattainable goal considering most tremendous.

  • 6. Why Cloud-hosted Virtual Desktops Make Sense Cloud computing has become a hot topic, supporting virtual desktops are gone. largely due to the flexibility and cost savings Cloud-hosted virtual desktops are easy to it can deliver. In much the same manner as buy and implement. The physical virtualization, cloud computing started on the infrastructure is already available from the server side and has begun moving to the provider, and companies outsource all desktop; the cloud is now ripe for desktop deployment and operations. This saves a infrastructure. significant amount of money that was traditionally spent on physical desktop By moving desktops to the cloud rather than maintenance, while minimizing the an internally deployed and managed data technical expertise businesses would center, businesses can realize all the otherwise need to leverage virtual promised benefits of virtual desktops— desktops. Additionally, because desktops centralized management, improved data are delivered by a provider over a secure security, and simplified deployment— without network and supported by a Service Level VDI’s costs, challenges, limitations or Agreement (SLA), end users can expect hassles. better availability of their desktops than could be delivered with physical PCs, • REDUCED DESKTOP COSTS: Because the physical infrastructure powering virtual which often require a desk-side visit when things go wrong. desktops is outsourced, IT organizations are immediately able to achieve a positive • DEVICE AND LOCATION ROI.

Cloudhosted desktops can be deployed by service providers on a global scale. This allows users to gain access to their virtual desktop from just about anywhere, and businesses to expand the regions from which they source talent, since they are no longer limited to corporate offices and a limited internal infrastructure. • Easy to Try and Buy: Because there is no infrastructure or software to deploy, businesses can quickly and easily try cloud-hosted virtual desktops before buying.
