The first item of note for users familiar with the first version of Windows Server is that the R2 edition is only available for bit systems. Whilst some editions of the original Windows Server operating system were available in bit versions, this is now no longer the case for the R2 version. The Foundation edition of Windows Server R2 is the new entry level edition and is designed specifically with the small business in mind. It is the least expensive of the various editions and lacks some of the more advanced functionality typically found in the higher end editions such as full Active Directory support and Hyper-V virtualization capabilities.
In addition, the Foundation edition limits some of the included features, such as restricting the number of concurrent remote desktop services connections to 50 and is able to access a maximum of 1 processor and 8GB of RAM. As previously stated, whilst the original version of Windows Server supported both bit and bit versions, the R2 version supports only bit processors.
However, we have Virtual Image Use Rights for the host physical instance and 1 virtual machine. The Enterprise edition provides additional hardware support and some additional server roles, when compared to Standard edition. Enterprise edition supports all available roles in full including Active Directory Federation Services. The Datacenter is similar to the Enterprise edition, but provides additional hardware support. Enterprise edition supports all available roles in full. This edition is intended to provide a low cost server edition for those who only want to use a web application server role.
Other roles are not available. The Itanium edition can be used on Intel Itanium 64 bit processor. There is no support for Terminal Services Gateway connections. Virtual Image Use Rights are unlimited. This bare-bones version of the software, without the standard graphical user interface GUI , provided command-line access to the server. This was a welcome change for administrators who were more familiar with Unix and Linux systems with existing command-line environments, and it made Windows Server an important competitive product for Microsoft.
The major change with this version involved the transition from being based on Windows Vista to being based on Windows 7. This brought the system to a bit environment. Many of the other updates were technical and not very visible to users, since they focused on supporting services. The release saw additional updates to Active Directory, this time in support of better group policy implementation. Additionally, DirectAccess and BranchCache were introduced, designed to provide better server access to users in remote locations.
These updates focused on improving the Hyper-V functionality, so it could be integrated into both local hosts and onsite delivery. This allowed the Hyper-V architecture to be easily used with other new cloud technologies.
PowerShell and Server Core were also updated with the release. The other major change was a new Essentials edition aimed at smaller, networked businesses. Windows Server R2 was released as an update to the prior release just a year later, in Many of the changes were improvements to functions needed to integrate with cloud services.
This included rewrites to both security protocols and network services. The release also saw more updates to PowerShell, among them the introduction of the Desired State Configuration system. This enhanced the management of network configurations. Another change involved improved functionality for storage systems, including better access for file sharing and replication of distributed files.
Web services were also enhanced, as were visualization systems. One major change came with the ability to serve software to mobile devices, which was important with the increased use of tablets. The next release was Windows Server , and it came with a new server option, Nano Server.
This was a scaled-down server implementation with limited interfaces, making it more secure from attacks. Another introduction with this release was Network Controller. This console program gave administrators the ability to manage all network devices, whether physical or virtual, from a single location. To support the use of containers, VM systems were enhanced to interact with Docker and to support encryption for Hyper-V.
Additionally, the release included Server Core. The Windows Server release only had Standard and Datacenter editions, and it did not have a follow-up R2 version. The most current Windows Server version is Windows Server It was released in October and included several important new features to meet growing networking requirements:. Some companies find it difficult to upgrade each time a new version of Windows Server is released.
Products in LTSC remain supported for a full ten years. This covers five years of support as part of the purchase, and another five years with a support contract extension. The R2 versions are the exception, since those are supplied as a free upgrade to customers who have the original version of the release. Subscribe to Article RSS.
