Enterprises, government agencies and other organizations are adopting desktop virtualization, or VDI, as a way to centralize and simplify desktop administration, reduce support costs and boost security. VDI may also lower capital costs for organizations moving to thin clients or a “BYOD” (bring your own device) strategy.

Challenges

Cost and complexity are usually the biggest challenges when deploying end user computing solutions. While VDI is often promoted as a technology that can save your business money, the initial upfront cost of deployment can be higher than traditional desktop replacement.

Savings from VDI are primarily operational expense reductions from centralizing administration. VDI implementation should also result in faster desktop deployment, enhanced security, less downtime and lower support costs.

With VDI, there are technical challenges to solve as well:

  • High availability (HA) and disaster recovery (DR): With VDI, a single server failure may affect tens or hundreds of users, while a more widespread data center outages can affect the entire user population.
  • Availability: Availability issues are complex as physical services (databases, controllers, gateways) requirecluster-based HA/DR while virtualized services (individual instances) require VM-based HA/DR.
  • Scaling up: This is usually a manual process as new server provisioning includes software, networking, I/O, storage
 and creating new physical machines vs. VM hosts are different/siloed processes.

Solution

DektpaaSEgenera Cloud Suite software, which includes PAN Manager, PAN Domain Manager and PAN Cloud Director, helps organizations implement Desktop as a Service while solving the issues of cost and complexity. Egenera Cloud Suite delivers a scalable and resilient platform that issimple to design and deploy, yet inherently protects against single server failure or an entire data center outage.
