More and more SMMEs are replacing existing PC workstations with "thin client" server terminals, says CCI Technology Solutions MD Steve Pinkney, with major benefits for productivity and network security.
"The principle of a thin client network is very simple," says Pinkney. "Instead of standalone desktop computers, users have simple terminals - it can be as basic as a mouse, keyboard and monitor plugged into a small device - that connects them directly to the server where all the processing takes place."
Hosting all applications on a single central server has several benefits. First, it enables a company to give its users access to the latest and most powerful applications without upgrading workstations on every desktop. Secondly, an older or less powerful PC can easily be converted to a thin client, extending its useful lifespan sometimes by several years.
Third, because no data or applications are stored by the client, network management and security are made much easier. "With thin clients users can`t download untested or unlicensed applications or import viruses on disks they bring from home or elsewhere," says Pinkney. "Everything happens on the server, which makes control and monitoring much easier."
It`s also easier to install security patches and updates. "Most people learn the hard way that it`s vital to keep up to date with security patches," says Pinkney. "With new Windows patches coming out almost every week, keeping all your workstations up to date very quickly becomes a major administrative nightmare. With a thin client network, you only need to do it once."
Thin client servers also facilitate systematic backups, a particularly dangerous issue for many SMMEs. "Many people skimp when it comes to making backups, and the consequences can be devastating," says Pinkney.
"Thin client servers are more expensive," he acknowledges, "and up to a certain point it`s probably easier to use desktop PCs. But a thin client network becomes viable much sooner than many businesses realise."
The trend to finance computer equipment rather than buy it outright can also help swing the decision, says Pinkney. "Service providers are getting very innovative in offering bundled packages of infrastructure, products, services and finance," he says. "If I could build my own IT infrastructure over again I`d definitely finance it. You get ongoing support and have the option to upgrade your equipment much more easily. It`s a big trend at the moment."
