MN504 – Networked Applications For Virtualization

About Citrix

Discuss about the MN504 – Networked Applications for Virtualization.

Currently whole Networking world is greatly influenced by Virtualisation. Virtualisation in Networking has no doubt brought a revolutionary change in the world of Networking and Communication. Virtualisation is a remarkable technology that helps to run multiple Operating System and Applications on a single server at the same-time. Virtualisation concept is most popularly given as-“One cloud, any application, any device” Architecture.  Virtualisation has helped to reduce the cost of IT for enabling networking not only for Big Enterprises but also helps in cutting down the IT Cost for Small and Middle Size Businesses too.  Virtualisation has not only helped in reducing the IT Expenses but also has helped in Boosting up the Efficiency and Agility of the Networking.

Case Study about Virtualization With respect to Citrix

South-Coast Medical Organization is  a charitable health care system with its headquarter situated at  New Bedford, Massachusetts. The South-Coast Health system owns three hospitals, twenty seven  Clinical offices, a Cancer Institute, Intensive care-  facilities (ICU),Emergency services, Medical labs and Radiology Departments, with the  Visiting Nurses service. South coast is also a fast growing Health care service System in New England too. This Health system has  employed approximately seven thousand workers in its Departments, including three hundred physicians and has two hundred  visiting nurses, with this it provides a wide range of medical services at each campus for Advance Medical facilities.  South coast’s mission is to provide “Advanced Care, Close to Home” for the patients it treats.

With this South-Coast Health System also has a goal to grow their organization in fast manner with providing exceptional Health care by providing distributed setting for their patients, through- outpatient centres by the help of newly acquired Physician practices?  The organization also desires to recruit and retain best Medical staff services for their Hospitals. For obtaining this goal, the organization plans to provide uniform access to the patient health records to the Visiting Doctors and Nurses regardless any device they are using for example Laptop or smart mobiles, Tablets etc. With this South-Coast Health care also demands the security of their patient’s information.  The South-Coast Health System along with above discussed clinical requirements also expects reduced cost in the IT Venture for their organization.

Major Challenge- To provide best Patient Health care facilities and facilitating the privacy of patient information in the distributed Mobile Environment.

The Solution-  Developing  an Integrated  Electronic Medical Record system and constructing the simple, securely developed mobile workstation that is required by the Hospital Staff.

1. Converting Patient Record into the EMR- To provide the solution of the above discussed issues, firstly the conversion of whole patient data into the Integrated Electronic Medical Record (EMR) through Citrix solution-Epic was developed. Now the Doctor as well the Nurses can access patient data either from their office or in Hospital using same user-id to access data from the Epic. With this Hospital Medical staff is now able to get the detail of the patient whether the patient is in Hospital or discharged to the visiting nurses services.

2. Facilitating Access of data with the help of any of Mobile Device of choice-  Secondly in order to provide the access of data through any of the Mobile Devices of choice, the rough idea of no of Laptops, Mobiles , PC’S in Network  was made, on observation approximately six thousand Personal Computers and Eight hundred Laptops in the network found. For providing the solution for this area the organization took help of Citrix solution by selecting Citrix -Remap and Citrix Xen-Desktop as the foundation to deliver its integrated EMR system along with Fifty  other clinical and nonclinical applications. Now the environment runs on the Cisco Unified Computing System platform and utilises the  Citrix NetScaler as a front end service. The organization also uses Citrix XenServer for all of the Citrix environments along with  Epic now. For providing the Advance Mobility features, the Southcoast chosed Citrix XenMobile as its enterprise mobility management solution. The  XenMobile helps to  handle the  mobile device management as part of its application, and it also provides the flexibility to support the bring-your-own-device policies. Now IT System of South Coast  are capable of  locking  devices, wiping data, upgrading and managing devices, and be proactive  in case of a security management-all while creating an fine medical  experience for  their users.

3. Making the fast organizational growth and maintaining the operational overhead at less than  percent of annual budget- With  the advance features provided by the Citrix , the organization now has progressed and achieving its targets.

4. Developing methods to protect sensitive patient information-   With the help of the  Citrix solutions, South coast organization now  keeps patient data safe and ensures sensitive information remains to be private. The new developed  infrastructure protects against data leakage and controls the inference of new mobile devices, even when the medical staff bring their own devices  in the premises.

“One best reason to select Citrix for our end-to-end platform is that it facilitates the Medical staff with a connected without interruption work for the hospital.”

Christian Boucher

Manager of Directory Services for Desktop and Mobile Engineering

Southcoast Health System

“Citrix provides the Facility to Medical Staff  to work  in from the office or the hospital, they use the same user ID to access Epic”

Mark Lacombe

Director of information technology

Southcoast Health System

“There are several chances when the Doctors  and nurses has to  face problems when the   system is in downtime, it also puts impact on the patient care. With the help of  citrix platform, we are capable  to refresh, upgrade and advance the environment without affecting operating of the services of Hospital,  which operates 24/7, 365 days a year.”

Conclusion

Virtualisation through Citrix is no doubt can be considered as the best practice for any organization. Citrix provides a number of advance services for  better working environment of the organization. Citrix is playing a  key role in bringing the advance features in the world of Networking. This was a simple student level approach the research of Citrix and Virtualisation is the wide field and research area.
