I have been asked by many server admins over the last year about Server 2008 R2, and every time the question essentially is, "So, is there any reason to run R2?" They ask this question assuming to already know the answer of "of course not" and are shocked when I tell them the answer is ABSOLUTELY. Now, this is just my opinion, but I believe that 2008 R2 is as big a leap from 2008, as 2008 was from 2003. Now, I'm sure I'll hear some detractors on this, but here is why I believe this to be true in all the ways that matter. So why is R2 so great? Well, ask yourself this. Do you think Windows 7 is far better than Windows Vista? If you answered yes, then ask yourself why? Got it? Well, the exact same reasons why you love Windows 7 over Vista are the exact same reasons you will love R2 over 2008. The resource utilization is vastly superior in R2 to 2008. In my real world experience, I have a good 33% more efficiency in an R2 server over a 2008 one. (That's not an actual benchmarked stat, that is my observation of servers in production.) Server 2008/Vista and Windows 7/2008 R2 are the same code base and kernel. In fact, the client OS's are now based on the Server OS's rather than the other way around. (This happened when they scrapped Longhorn 4000 series builds and based the new code on Server 2003 rather than XP code base.) Now, there are many new features/improvements over 2008 in R2, but I'm just going to address a few and provide you links to learn about the rest; Hyper-V R2 – The new Hyper-V has many new features including live migration features, greater than 32GB RAM support/ >4 proc (host), etc. Plus, it's free. To learn more, go here - http://www.microsoft.com/hyper-v-server/en/us/default.aspx Direct Access – This is the most advanced feature added to Windows Server since well, maybe Active Directory itself. Now, while I lay claim to some credit of getting this feature into the OS (can't talk about it :-) ) I about had a heart attack when it actually made it to the product. What is Direct Access? Are you familiar with RPC over HTTPS, now called 'Outlook Anywhere', which is where your Outlook connects securely to Exchange without a VPN and all traffic just goes over port 443? Well then, Direct Access is the same concept, except we're talking ALL DOMAIN TRAFFIC. That means you can domain manage laptops in remote offices or at users home the EXACT SAME WAY as you would if they were on your local LAN. That means they talk to the domain before the user even logs in, applying computer and user group policies (including software deployments) access to local file and print shares, etc. You are literally looking at domain controlled computers over the WAN with no VPN's, MPLS, etc. Users don't have to change a thing, when the laptop is at work and when they are home, everything just WORKS! A couple of notes; First, this requires all client computers be Windows 7+. It uses some new protocols that Microsoft has implemented. A quick layman's description, RPC inside of IPSEC inside of SSL. I've had the documentation detailing exactly how the security layer of all this works and given it to a DOD security contractor to review. I was told it was the most secure commercial implementation he had ever seen, and thought it may even be impervious to 'man in the middle' attacks. Again, this was only his opinion, but I trust his opinion. In summary I cannot stress this enough. LEARN ABOUT DIRECT ACCESS. Get started with an over-view here - http://www.microsoft.com/downloads/details.aspx?familyid=D8EB248B-8BF7-4798-A1D1-04D37F2E013C&displaylang=en IIS 7.5 – Don't be scared, this isn't the leap of IIS 7 from IIS 6. Far from it, just keep the same concepts of Windows 7 over Vista in mind here. It's IIS 7 streamlined and more efficient. Enough said.
