> our services > citrix & thin client consultancy

More and more companies are moving towards 'thin client' technology as a solution to reduce ever mounting IT costs and here at Jade Integration we aim to make the transition as painless as possible. The majority of larger conglomerates, including NatWest, BP, Jaguar, T-Mobile and Lloyds TSB, either have or are currently investing heavily in thin client technology, however these are companies with their own IT departments and support staff. To help level the playing field, Jade Integration can implement thin client solutions for SMEs as well as provide consultancy to larger organisations. If you currently have between 10 and 10,000 PCs you could be a prime candidate for a 40-50% reduction in IT costs.

What is 'thin client' technology?
To truly appreciate thin client technology we would highly advise coming to our offices for a free demonstration - it's much easier shown in practice than explained! In a 'normal' corporate environment (also known as a 'fat client' environment) you'll have a selection of servers which store data, and a selection of PCs which your users use to access the data. In most cases the PCs are doing most of the 'work'. They run all of the applications like Word, Excel, Access, bespoke applications etc. and, in practice, the servers do very little work. In a thin client environment, your PCs are replaced with inexpensive dumb-terminals and a central server, known as a 'terminal server', does all of the work.

Why is this better than a 'fat client' environment?
The biggest single advantage is cost. Typically a thin client environment costs 40-50% less to implement and manage than a similar fat client environment. Thin client terminals cost as little as £140 each, they consume around 80% less power and, above all, there's no longer a requirement for desk-side support. The terminals have no moving parts and they configure themselves automatically. If a terminal develops a fault (and they're around 200% more reliable than PCs) just unplug it and plug a new one in! All of the complicated stuff, like configuration and application deployment, is done centrally from the terminal server.

Am I not putting all my eggs in one basket?
Nope! You can have as many terminal servers as you like for resilience. The servers (known as a server farm) will automatically load balance between each other to ensure new connections are only established with the quietest server.

Jade Integration are Wyse Gold Partners and official resellers of Wyse thin clients.

With a Citrix Business Alliance, our staff are CCA and CCEA certified.

How many clients can one server handle?
This is largely dependent on what your users are doing but as a general rule of thumb you can have 50-80 users on one properly set-up server, but we've seen as many as 200! As mentioned, this is largely down to how the server is configured - some companies may purport that only 10-20 users can utilise the same server concurrently. While this may be the case for unusually processor intensive applications, for day-to-day activities, such as typical office applications and e-mail, if your server can only handle 10-20 users something is seriously wrong.

What is Citrix?
Citrix Metaframe (or Citrix Presentation Server as it's now known) is a piece of software which gets installed onto a terminal server to greatly enhance performance and functionality. Normal terminal servers rely on a protocol known as 'RDP' for communication. While this is highly efficient, Citrix have further enhanced this through their 'ICA' protocol. It basically makes the whole terminal server experience much faster and more useable over slow connections (such as dial-up or broadband). In addition to this Citrix adds a feature known as 'Published Applications'. This makes application deployment far simpler - instead of having to go 'round 50 PCs to give them a new program, install it once on the terminal server(s), set up a published application, put your users in the relevant group for that application and that's it! When it comes to giving another user access to the same application - just add them to the group! There are a wealth of other features available too - for more information we would highly recommend coming to see us or visit our stand at any forthcoming exhibitions.

Is the deployment complicated?
No - it's incredibly simple - indeed it can all be done in parallel with your existing infrastructure. Just about any device can access a terminal server - including PCs, so you can phase deployment over a period of months and only replace the PCs once every single application has been successfully ported over to the terminal server environment. Of course you'll only start to reap the full benefits of thin client computing once your new terminals have been deployed and your PCs are in a skip.

Do I need to get rid of ALL my PCs?
No - indeed we wouldn't advise this. It's normal practice to leave your 'power users' with PCs and thin client terminals are no replacement for laptops since they are useless without a network being present at all times. A thin client solution is ideal for any company with a lot of staff who all carry out similar tasks - call centres are a prime candidate, although any company who primarily use the standard 'Office' suite of applications can benefit greatly from this technology.

Where do we go from here?
We'd be more than happy to provide you with a FREE demonstration of this technology - you can either visit our offices to see the equipment first-hand, or we can show you it remotely over your existing internet connection. Call us on 0191 273 4444 or e-mail enquiries@jadeintegration.com to book an appointment or obtain a quotation.
