Increased innovation in virtualization, compute and networking technology is steadily increasing the growth and adoption of VDI. Many enterprises are extending VDI deployments to their remote offices and branches but many are also apprehensive of running VDI across the WAN link due to concerns that a single point of failure could disrupt the entire business at a remote location. Similarly, small and medium businesses (SMBs) are exploring VDI. For them to adopt VDI the offered solution needs to be simple, reliable, and able to incorporate other business needs like office communications, PCI compliance, business continuity, etc. They prefer solutions that provide a healthy TCO and can also be deployed and managed easily.
