1. Welcome! Developing a truly virtual infrastructure :
What do you need to consider ?
Andy Eccles Enterprise Solutions Architect

2. Todays Objectives Agenda Don’t just virtualise, optimise
Server Virtualisation
Virtual Desktop
Application Delivery
Assessment Offer

3. More than just a buzzword
Optimise!
More than just a buzzword
Today’s businesses are demanding more for less
Almost everything can be ‘virtualised’ – but is it a good idea?
A hybrid approach is becoming common with solutions from different vendors being integrated together
Agility is critical, don’t design yourself into a corner

4. Server Virtualisation
Fewer and fewer important considerations
What servers can be virtualised?
So many Windows/x86 servers run at only peak 5% CPU!
Consolidation has significant benefits for these servers
Some services do deserve their own hardware
But the agility of virtual servers is a very useful attribute
Don’t expect a quart from a pint pot, sizing is important
Limitations
Some hardware components can be difficult (GPU, etc)
Very heavy I/O can suffer virtualisation overhead

5. Server Virtualisation
Hypervisors and storage
Hypervisors and Management
Microsoft Hyper-V, Citrix XenServer, VMware ESX
It’s the management and infrastructure that matter
Using appropriate storage is essential
Yes, you can use local storage in Virtualisation Infrastructure
But enterprise-class storage is essential for full flexibility
Performance
High Availability
Snapshots
Replication
Deduplication

6. Application Delivery So many choices...
What’s the point of all of this?
To get applications to your users
Terminal Services, Virtual Desktop, all very good but...
Connectivity is a significant part of the requirement
Don’t forget about the humble desktop, you might need some!
Limitations of Server-Based Computing
App support... Bear in mind that some can be worked around.
Getting the applications onto the servers or desktops
Stream apps from a central single instance where possible

7. Traditional Desktop PC!
How does it look?

Basic SBC flowchart
Help to give an initial indication of what to use
A rough guide
Some of the ‘rules’ can be broken
ISC always tailor designs, no one-size-fits-all approach
Third-party products can help to bypass some SBC limitations

11. When is SBC the wrong tool?
The challenges and considerations
Link latency must not be excessive
Over 100ms can be difficult for RDP
400ms or more for Citrix ICA with tuning
Satellite BB is a bit of a challenge
If you can’t rely on consistent connectivity for your users
Heavy graphics and some multimedia are a challenge today
Wyse, HP, Citrix, Microsoft even Qumranet are helping
Peripherals can be a pain to connect and manage
Certain connectivity requirements can be difficult (IPSec VPN)

12. My idea of an ideal deployment
Take a hybrid approach
My idea of an ideal deployment
Use Terminal Services with XenApp where required for best value
Use full desktop PCs where SBC just doesn’t fit
Implement a good SSL VPN to provide web-based users with a desktop from anywhere, any time, on any device...
Use VDI for the ‘others’ - and make the most of single-instancing
Virtualise applications where possible, or deliver some of the applications seamlessly into the virtual desktops using TS/XenApp!
Ensure you work with a qualified and experienced partner for design and implementation

How we work
in the ISC Enterprise Solutions Group
We are a team of subject-matter experts who also understand the impact of our subject on infrastructure as a whole
Our strength is in integrating technologies, possibly from different vendors, to provide a coherent solution
We don’t use a one-size fits all template for infrastructure, each scenario is analysed independently
ISC Solutions Architects are funded internally to provide balanced advice to customers, not commissioned to sell

14. with the ISC Enterprise Solutions Group
Analysis Offer
with the ISC Enterprise Solutions Group
We offer no-obligation assessment/analysis meetings
Our subject-matter experts are available at no cost
These meetings typically take between one and two hours
We are flexible with proposing new solutions or development of existing infrastructure
There are boxes on your feedback forms to tick if you’d like to take the opportunity of meeting our people
Application delivery, desktop and application virtualisation
Server virtualisation, consolidation and agility
Storage consolidation, flexibility and protection.
