Your clients and employees need access to your data instantly to work at their best and common sense says that having an on-site Desktop as a Service server will provide the fastest connection. Hosting a DaaS server in your office can open your data up to many easily avoidable vulnerabilities however, and the speed that you obtain through on-site hosting is often negligible to your users. Additionally, your IT department will spend a lot of their time maintaining, patching and troubleshooting this DaaS server where they could be using their time to optimize your infrastructure and finding ways to better use available technology for your business.
Even if your IT department is prepared for such a project, they may not be versed in all the problems that can arise along the way. Using a third party like iTecs to create and support a Virtual Desktop Infrastructure for your company can be a cost effective and agile solution to this issue.
