Windows Server 2008

Windows Server 2008 is a surprisingly diverse product, with some very small new enhancements that could be easily overlooked, and some large high profile additions that Microsoft is certainly not allowing anybody, including the media, to overlook. However, what is the balanced view on Windows Server 2008.
Firstly, it has an inbuilt Hypervisor – a Hypervisor enables the virtualisation of the commodity server hardware so that it can support the execution of multiple Virtual Machines. Hyper-V, as it is known, is not the most technically advanced Hypervisor on the market, that award goes to Vmware, but it is a very good basic Hypervisor with a couple of interesting features: The ability to execute a Xen based Virtual Machine, and the concept of synthetic device drivers – the synthetic device drivers are the new high performance device drivers that are available with Hyper-V, rather than emulating an existing hardware device Microsoft exposes a new hardware device that has been designed for optimal performance in a virtualised environment.
One of the smaller and easier to overlook features of Windows Server 2008 is the ability to have a finer grained password policy, which may sound dull, but consider the IT department that is supporting ‘C’-level executives who do not necessarily have the time, or inclination, to maintain a complex alphanumeric 10 character password that is forced to be changed every 30 days. This finer control allows for these users to have different rules to say a database administrator, which enables IT to ensure that password policies are designed appropriately for the role/purpose of the account.
The other big feature of Windows Server 2008 is the introduction of server core, a stripped down operating system. This according to Microsoft requires up to 40% less patches to be applied, and occupies significantly less disk space than for the full Windows Server 2008. I consider this to be a major advancement, which will enable organisations to install server core on systems such file and print servers, reducing the maintenance required, and hence the operational cost.
Other features that are worthy of a mention at this stage include; role-based installation of features, simplified clustering using the wizard concept, read-only domain controllers, modified boot process that brings the firewall up earlier and so reduces the window of vulnerability, and the use of Network Access Protection (NAP) so a health policy can be set for anything connected to the network.
