AMS - VIRTUAL DESKTOP SUPPORT
Reducing capital costs, decreasing operating expense, centralizing IT support, adding built-in disaster recovery and improving overall security are just several of the reasons driving increased adoption of virtualized environments. Whether hosted on a private cloud, public cloud or a hybrid thereof, AMS can design, deploy and support your virtual environment.
DATA CENTER AND ON-PREM SOLUTIONS
Depending upon individual needs and the size of your enterprise, several virtualization technologies exist. HCI, or hyperconverged infrastructure, is the primary foundation upon which compute, storage, infrastructure and networking are combined into a single IT stack upon which virtual servers and desktops are delivered.
Combining and replacing traditional IT infrastructure within a single stack allows a firm to shift CapEx to OpEx, which is yet another strategic reason for virtualizing desktop environments. For organizations with 50 or more employees, an HCI solution should be one of your first considerations together with cloud services in your migration to a virtualized environment.
Whether hosted on a cloud or on-prem, virtual desktops are typically provided via Remote Desktop Services, (RDS) or VDI to deliver remote applications or provide secure desktops. While other protocols exist, the great majority of Virtual Desktop deployments are delivered via RDP or VDI over a display protocol such as SPICE, RemoteFX, PCoIP or similar.
Going to a fully hosted solution does have cost advantages. But it also comes with additional risks. Loss of connectivity can cause down time. So, to mitigate risks while still taking advantage of a fully hosted solution, redundant connectivity should be a consideration. In such a case, any interruptions would be minimized until your primary connection is restored.
Each VDI or RDS provider approaches security a bit differently. However, many share similarities in common. Azure, for instance, which AMS supports, delivers RDS over SSH or RDP via SSL. Called Bastion, Azure’s PaaS (platform as a service) provides off-internet VMs that are not subject to discovery by port scanners. Utilizing private IPs, this is by design to increase overall security and control access. The following topographic depicts security in a typical Azure virtual desktop deployment.

Built-in fault tolerance
The ability to recreate VMs from snapshots on demand means that fault tolerance is one of the built-in features of VDI. VMs can be recreated in minutes from snapshots with no or minimal data loss (depending upon the technology employed).
High-availability configurations in Azure Bastion’s RDS are by nature more complex. But, in that they are also more robust insomuch as distributed enterprises with geographically dispersed locations would be served better by such solutions.
