Rolling Review: Windows Server 2008 Makes Upgrade Sense For Some
Sites that need basic terminal services or server consolidation have the most to gain--for now.
Is it worth it to upgrade to Windows 2008 Server now? After nearly a year of kicking the tires on this release, our short and anti-climactic answer is, "It depends."
For basic terminal services or server consolidation needs, Server 2008 is worth upgrading to immediately. All other improvements, including network access control, are nice value-adds, but are no reason, in and of themselves, to make a fast leap to Server 2008.
Unlike any server operating system that Microsoft has released to date, Windows 2008 Server comes chock-full of new enterprise features that go well beyond the file, print, directory, and core network services of old. In the previous editions of our Longhorn Rolling Reviews, we profiled some of these new capabilities: TS 2008, Windows PowerShell, Network Access Protection Server Core, and Hyper-V.
TERMINAL SERVICES 2008
Terminal Services is not new to the Windows Server line, but TS 2008 is unrecognizable compared with previous editions. New features -- such as the ability to run individual applications via a seamless TS window, instead of having to launch an ugly TS session in order to execute an application -- make TS 2008 much more Citrix-like than before. In addition, you can now launch an application or a full desktop directly from the Internet via a TS 2008 Gateway server. Getting TS Gateway to work in the lab was somewhat cumbersome, but once we configured it properly on the back end, and after we deployed the new Remote Desktop Protocol client to our Vista machines, we saw impressive and steady performance as we scaled up to 50 simultaneous connections on a single box. And TS 2008 now provides a Web-based portal that allows corporate or third-party users to access internal applications remotely and without need for a VPN client.
STACKING THE DECK
Longhorn and Vista modifications make more efficient use of network resources.
The Web Application Portal feature is the major difference between TS and Citrix. With TS 2008, you either present an application on the Web portal or you don't. The Citrix-supplied Web portal provides management and security capabilities that allow you to control which applications are available based on login credentials. Also, to serve applications to contractors or third parties, you'll need to buy an External Connector license (which lists for $7,999) for Terminal Server.
TS 2008 is a great solution for small to midsize enterprises with relatively small TS needs, yet it's still versatile enough to service midsize organizations. However, larger sites that have more complex load-balancing and performance needs should continue to make the incremental investments in Citrix.

Google in the Enterprise SurveyThere's no doubt Google has made headway into businesses: Just 28 percent discourage or ban use of its productivity products, and 69 percent cite Google Apps' good or excellent mobility. But progress could still stall: 59 percent of nonusers distrust the security of Google's cloud. Its data privacy is an open question, and 37 percent worry about integration.
