The health system is having around 100% of uptime. It has met the big increase in the session support for the concurrent along with $1 million of savings from the reduced support and cost for operation.
Sentara Healthcare is a health system in Norfolk, Virginia, and comes up with an Epic electronic health record. This connects 12 hospitals along with various clinics on a similar platform. It is also giving the clinicians the capability to have access to the record exchanging of patients in a quicker manner.
As Matthew Douglas, the chief enterprise architect at Sentara Healthcare, says, Epic presents its clinicians with a layer of presentation. This is completely web-based. At the same time, it comes with seamless integration along with the Epic EHR products. Also, he further added that the team is deployed with the presentation layer along with Citrix XenApp. It had a physical infrastructure that was quite hard to maintain.
In the meantime, Sentara faced challenges like scale and cost. As Epic came up with its frequency for the code releasing, Sentara continued to scale up by adding more to the servers to meet the demand of the capacity for Epic.
As Douglas says that, a solution is needed to improve the transparency of the system and the complexity.
Sentara is also the first one to come up with the deployment of VMware’s RDSH vendor with Epic. The RDS host is a server computer that hosts plenty of applications with the desktop session to provide remote access.
Through the VMware Horizon Client, the layer of presentation has become fully virtualized. However, Sentara sees a significant improvement in performance and stability. As the deploying took place with the VMware solution. The performance and resilience have increased in a significant way. They started with the concurrent sessions at around 12000-13000, and now it is supporting 16000-18000 sessions.
The virtualizing of the desktop has also minimized the wide-spreading in the number of security breaches. The mages and the data are getting the hosting from the centralized servers in spite of the machine of end-users.
