Virtually perfect - the way forward for Primary Care Computing
Mark Gibbs, Head of Primary Care
2
Virtualisation – The Background
Virtualisation started with Mainframes in the 1960’s
Concept was to split the computer into a number of Virtual machines
PC’s are now powerful enough to handle multiple tasks
VMWare is the market leader for Windows based technologies
3
Virtualisation – The Background
The market trend has seen a accelerating move from Mainframes through to client server relationships and now moving on towards virtualisation
4
So what is Virtualisation?
Traditionally each Machine whether a server or PC runs an operating system and a set of applications
5
So what is Virtualisation?
Virtualisation adds a new layer to the machine meaning it can run multiple operating systems
6
So what is Virtualisation?
From the users perspective this is no different to connecting to a physical server
7
Secure and sharing at the same time
Although there can be many instances of virtual machines on a single server, they are separated from each other and protected from each other
8
Benefits of Virtualisation
Simplified server management – encapsulation
9
Hardware Independent Moving a server on to a virtual server is not reliant on the hardware, the
virtual server is independent of the physical hardware
The virtual machine can have a virtual server installation that was previously a Dell server running on the same machine as one which was a HP server etc.
10
Virtualisation Implementation in the business
The Virtualisation Process takes a dynamic mapping of the resources required by the business
The result is an easier to manage, more efficient, more responsive service
11
Virtualisation Solutions
There are different models that can be implemented
12
Virtualisation is well established
13
How can this affect the future of Primary Care
Typically in a Primary Care setting a GP Practice will have a server and client PC’s all housed within the physical building
Virtualisation can replace the physical servers
with virtual servers
14
Benefits of Virtualisation
The virtual servers can be hosted in a resilient data centre
Load balancing on the data centre manages the utilisation – providing extra resources when needed, no more slow practices because a report is run
Even though this is a data centre housed environment the practices data is protected from other virtual servers – The practice ‘own’ their own virtual server and the clinical database
Back ups and updates to software are a managed service reducing administration costs for the practice.
Technology refreshes are not required at the practise for servers, reducing the cost of the provision to the PCT’s
Using thin client technology i.e. Citrix allows the virtual server to provide services over N3 with very small bandwidth requirements
15
Benefits of Virtualisation
Best of both worlds – the practise own and can administer the server as if it was in their own cupboard and yet it benefits from the same resilience and availability of a data centre hosted enterprise solution.
Moving to a virtual server is not a complicated data migration, the same software runs on the virtual server as ran on the practice based server, it is only the location of the server that changes
16
Theory or Reality
This might all sound really interesting but does it really exist
Virtualisation is already been utilised at large organisations
iSOFT are introducing this as their hosted solution under GPSoC

Synergy running on a Virtual Server
This will be hopefully the most boring demo you will see and yet the most powerful.
I will connect to Synergy from my desktop that is running on the virtual server and the software you will see is…..

Synergy – exactly as it looks now. There is no difference!
19
Changes that will be made
There are changes that will have to be made, Synergy printing for instance
New services as standard –
• iSOFT are looking to have the best of breed 3rd party applications as the ‘core’ software under the Virtual Synergy service, we need to come to an agreement with the 3rd parties, but we would look to use Frontdesk as the appointments system and have a built in Scanning solution.
• Other 3rd party products can still be installed and run on the Virtual Server, just as they do now, we will not restrict you from what you run and when.

What are the draw backs?
You lose the enjoyment of changing back up tapes
You can’t use the server running slow as an excuse to go home and do that tomorrow. The availability and performance are guaranteed by our contract with CfH
You don’t decide when upgrades are performed we do them all overnight when software updates are available
