Thin Client, Or Fat Client? That Is the Question
theodp writes "If virtual desktops are so great, asks Jonathan Eunice, then why isn't everyone using them? However encouraged folks are by the progress virtual desktop infrastructure (VDI) has made, and however enthused they may be about extending the wins of server virtualization over into the desktop realm, you don't see analysts and developers eating the virtual desktop dog food. And even the folks you meet from Citrix, Microsoft, Quest, VMware, and Wyse — the people selling VDI — use traditional 'fat' notebooks. So, are you using virtual desktops? Why, or why not?" I wonder how long the abbreviation VDI will stick around.
The promise of thin clients has never been on upfront costs. The advantages have to do with maintaining the clients once they have been deployed. Think patches, service packs, O/S upgrades, memory upgrades, HD replacements, etc. With traditional desktops many of these changes can only be done by going to each machine individually. Additionally, thin clients make backup/restore trivial whereas trying to enforce data retention standards on desktops is always a battle. While these issues may not present themselves in a small to medium sized company, trust me when I say that with thousands of installed desktops there are hundreds of people dedicated to maintaining the hardware and managing the environment.
I'm not sure what you mean by "there aren't suitable thin client options for most businesses." Most of the actual business of say a bank, or an insurance company, or a web vendor, or just about any company that isn't a full fledged software developer comes down to a few apps that rarely require huge amounts of memory, the latest video card, or even a hard drive since most of those apps just run as a client and save data on the server anyway. In fact I can think of few businesses where thin clients shouldn't represent the majority or installed systems.
I've done contract work for one of the major credit card companies as a data analyst, and they require us to go through Citrix clients (among other hoops) for a very simple reason: security. There is no way for us to perform an end-run around all of their security for the simple fact that they control our environments, tools, everything. It doesn't matter what kind of system we have (Windows, Mac, Linux, bottom-of-the-line laptop or ass-kicking Alienware), we're limited by the environment that they set up for us.
They could easily pay triple what it's costing them, as long as their security measures are in place, that's what matters most.
