Windows Server 2008 most of the drastic changes

The Microsoft Windows Server 2008, most of the important changes that were made, we'll never see, we can will feel these changes. And I really believe that in the future, we will look back at the Windows Server 2008 release and say wow that was a milestone, very similar to the way we look back on Windows 2000 and the introduction of Active Directory right now.

The most of the architectural changes that Microsoft chose to make on the Windows Server 2008 product is going to open the new mathode and lay the foundation for some pretty significant lurches forward if we will on this platform. First off, they made some significant kernel
changes to provide better processor virtualization support. And this is just going to give you faster, better, leaner operation.

The some of driver model changes, this just makes our drivers more stable and more secure. this is very protective feature. Obviously, drivers are a huge thing, almost anything we attach to the computer has to have a driver. And so to make these drivers more secure, more stable means less restarts, less lock ups, and so forth.

The Microsoft fully re-write the TCP/IP protocol stack, now we are going to hear me mention this a more million times in the course of this entire series because this is a huge thing. They did it for better performance, we should remember, as bandwidth goes up, we keep moving more and more data.

Now we going to begin the consume more and lot of XML, because there is a many work being asked of processors. So want more efficient ways to transfer larger packet of data, more reliable transportation of that data, so they've rewritten that TCP/IP stack to help with that.windows server 2008 also support IP version 6. we can say This is going to be a milestone.

Now we discousing about IP version 6, but that's huge. Now, Microsoft made some major architectural changes to the way memory is managed and the many way is manage. Now if we don't know what the heap is, don't worry about it, but as the amount of memory that we require on our machines and that our machines are being asked to manage and deal with, as that goes up, obviously it becomes more important that we handle it faster and more reliably so that's what's happened here.

Microsoft's has been many changes to the registry to make it perform better, they've also given it transactional support for reads and writes, and they've made some other changes, but again, the registry is a fundamental part of the Microsoft Operating System and quite honestly, it can turn into a bottle neck really quickly and a registry can become a problem and so they've made some pretty serious enhancements there.

Now, let's talk about probably the number 1 change that has been made to this operating system, you will notice this one, you may not realize why it's such a big deal but it is the introduction and the inclusion of the .NET Framework 3.0 version. Now, this is what gives
Vista its distinctive slicker, sexier, graphical look and you're going to see this in Windows Server 2008.

It's not as apparent in Windows Server, but what's going on underneath is what's making the difference. And there's 4 basic parts to the .NET Framework. The biggest thing about the .NET Framework is that it totally absolutely separates the client aspects of anything to do with the Windows Server platform from the services that the platform of the server provides.

Now, those services have been totally separated, totally object oriented so they can be easily distributed across machines across the Internet around the world, there does not absolutely need to be all the servers in the same room anymore by any standards. The first one up
is the WCF, this is codenamed Indigo, it is the Windows Communication Foundation, and this is where the new IPC Communication Stack resides. This gives the system the ability to communicate across different typologies and architectures.

This specifically gives the Windows Operating System to retain backward compatibility with older products, and again, it gives you that generic treatment of what's going on in the computer world now, that everybody needs to compete. And everybody needs to communicate on a level playing field. The second aspect on the .NET Framework is the WPF and this was codenamed Avalon and that is the Windows Presentation Foundation.
