Mainstream support ended on April 12, Extended support ended on April 12, [11] [12]. Windows Server is the second version of Windows Server operating system produced by Microsoft. It is part of the Windows NT family of operating systems and was released on April 24, An updated version , Windows Server R2, was released to manufacturing on December 6, Windows Server is based on the consumer operating system, Windows XP. Windows Server is the follow-up to Windows Server, incorporating compatibility and other features from Windows XP.

Unlike Windows , Windows Server ‘s default installation has none of the server components enabled, to reduce the attack surface of new machines. Windows Server includes compatibility modes to allow older applications to run with greater stability. It was made more compatible with Windows NT 4. Windows Server brought in enhanced Active Directory compatibility and better deployment support to ease the transition from Windows NT 4.

Windows Server is the first server edition of Windows to support the IA64 and x64 architectures. The product went through several name changes during the course of development. When first announced in , it was known by its codename “Whistler Server”; it was named “Windows Server” for a brief time in mid, followed by “Windows.

NET Server” and “Windows. NET Server “. After Microsoft chose to focus the “. NET” branding on the. Windows Server was the first Microsoft Windows version which was thoroughly subjected to semi-automated testing for bugs with a software system called PREfast [17] developed by computer scientist Amitabh Srivastava at Microsoft Research.

Microsoft co-founder Bill Gates stated that Windows Server was Microsoft’s “most rigorously tested software to date. Microsoft used Windows Server ‘s kernel in the development of Windows Vista. Windows Server comes in a number of editions, each targeted towards a particular size and type of business. NET technology. Domain controller and Terminal Services functionality are not included on Web Edition.

However, Remote Desktop for Administration is available. Only 10 concurrent file-sharing connections are allowed at any moment.

NET Framework version 2. When using it for storage or as a back-end with another remote server as the front-end, CALs may still be required. Microsoft Windows Server Standard is aimed towards small to medium-sized businesses.

Standard Edition supports file and printer sharing, offers secure Internet connectivity, and allows centralized desktop application deployment. A specialized variant for the x64 architecture was released in April Windows Server Enterprise is aimed towards medium to large businesses.

It also provides the ability to hot-add supported hardware. Windows Server Enterprise is also the required edition to issue custom certificate templates. Windows Server Datacenter is designed [25] for infrastructures demanding high security and reliability. Windows Server is available for IA, Itanium, and x64 processors.

It supports a maximum of 32 physical processors on IA platform or 64 physical processors on x64 and IA hardware. The Datacenter edition, like the Enterprise edition, supports 8-node clustering. Clustering increases availability and fault tolerance of server installations by distributing and replicating the service among many servers. This edition supports clustering with each cluster having its own dedicated storage, or with all cluster nodes connected to a common SAN.

Windows Compute Cluster Server CCS , released in June , is designed for high-end applications that require high performance computing clusters. It is designed to be deployed on numerous computers to be clustered together to achieve supercomputing speeds. Each Compute Cluster Server network comprises at least one controlling head node and subordinate processing nodes that carry out most of the work.

It ties nodes together with a powerful inter-process communication mechanism which can be complex because of communications between hundreds or even thousands of processors working in parallel. The application programming interface consists of over functions. A job launcher enables users to execute jobs to be executed in the computing cluster.

Windows Storage Server , a part of the Windows Server series, is a specialized server operating system for network-attached storage NAS. Launched in at Storage Decisions in Chicago, it is optimized for use in file and print sharing and also in storage area network SAN scenarios. It is only available through Original equipment manufacturers OEMs. Windows Storage Server NAS equipment can be headless , which means that they are without any monitors, keyboards or mice, and are administered remotely.

Such devices are plugged into any existing IP network and the storage capacity is available to all users. Multiple such NAS servers can be clustered to appear as a single device, which allows responsibility for serving clients to be shared in such a way that if one server fails then other servers can take over often termed a failover which also improves fault-tolerance.

Windows Storage Server can also be used to create a Storage Area Network , in which the data is transferred in terms of chunks rather than files, thus providing more granularity to the data that can be transferred. This provides higher performance to database and transaction processing applications.

Single instance storage SIS scans storage volumes for duplicate files, and moves the duplicate files to the common SIS store. The file on the volume is replaced with a link to the file. Windows Storage Server R2 provides an index-based, full-text search based on the indexing engine already built into Windows server.

Windows Storage Server can be promoted to function as a domain controller; however, this edition is not licensed to run directory services. It can be joined to an existing domain as a member server. Windows Small Business Server SBS is a software suite which includes Windows Server and additional technologies aimed at providing a small business with a complete technology solution. SBS has the following design limitations, mainly affecting Active Directory: [30].

Windows Home Server was announced on January 7, , at the Consumer Electronics Show by Bill Gates and is intended to be a solution for homes with multiple connected PCs to offer file sharing, automated backups, and remote access.

Intended use was for building firewall, VPN caching servers and similar appliances. Availability of the original version ended May 28, Availability of R2 ended March 5, End of extended support was July 14, all variants except Storage Server [9] , and End of Licence was May 28, R2 and original. All variants continued to receive Critical security updates until the end of extended support: [37].

While many features of the bit variant of Windows XP were brought over into Windows XP Professional x64 Edition, other limitations imposed by constraints such as only supporting bit drivers, and support for bit programs being dropped led to incompatibilities with the bit Windows XP editions available. Among the improvements are many of the same updates that were provided to Windows XP users with Service Pack 2.

Features that are added with Service Pack 1 include:. A full list of updates is available in the Microsoft Knowledge Base. Service Pack 2 for Windows Server was released on March 13, This was followed by build , known as Beta 2 Refresh.

The final build is Microsoft has described Service Pack 2 as a “standard” service pack release containing previously released security updates, hotfixes, and reliability and performance improvements. Service Pack 2 also adds Windows Server Scalable Networking Pack SNP , [48] which allows hardware acceleration for processing network packets, thereby enabling faster throughput.

Windows Server R2 is an updated release of Windows Server , which contains a copy of Windows Server SP1 on one CD and a host of optionally installed new features on another disc, similar to Microsoft Plus! New features of Windows Server R2 include: [51]. On July 13, , Windows Server ‘s mainstream support expired and the extended support phase began.

During the extended support phase, Microsoft continued to provide security updates; however, free technical support, warranty claims, and design changes are no longer being offered. Although Windows Server is unsupported, Microsoft released an emergency security patch in May for the OS as well as other unsupported versions of Windows including Windows Vista and Windows 7 RTM without a service pack , to address a vulnerability that was being leveraged by the WannaCry ransomware attack.

Anonymous users from managed to compile the Windows Server source code, as well as a Twitter user who posted videos of the process on YouTube proving that the code was genuine, [57] but was removed from the platform on copyright grounds by Microsoft. The leak was incomplete as it was missing the Winlogon source code and some other components.

Microsoft issued a statement stating that it was investigating the leaks. From Wikipedia, the free encyclopedia. Server operating system by Microsoft released in This article has multiple issues. Please help improve it or discuss these issues on the talk page.

Comparison of Standard and Datacenter editions Windows Server | Microsoft Learn – Navigation menu

Moreover, you can also use a free-of-cost license categorized as an evaluation license. However, these are only valid for a limited time, after which the Server installation will no longer be functional. Note: There was no concept of the different Server editions before Server This means it is offered in 3 different editions: Plain, Advanced, and Datacenter.

The table below highlights the major differences and similarities between the Standard and the Datacenter editions of Windows Server:. The Standard edition of the Server is based on Client Access License CAL requirements, which is a commercial software license that allows multiple client computers to use server software services.

The Standard edition includes all of the features in the Essentials edition and more. In case of more Virtual Machines VMs , you will need to purchase more licenses. It also allows you to integrate with the Azure cloud and manage accordingly, creating a centralized managed environment.

You can also synchronize file servers and share data throughout your organization. The Datacenter edition is for organizations that need highly virtualized and cloud-integrated environments. In comparison to the Standard edition, you can create unlimited VMs, but only one Hyper-V host, like the Standard edition.

One distinct feature that the Datacenter edition offers is the Network Controller. Using this tool, which the Standard Edition does not offer, you can monitor, manage, control, and troubleshoot your virtualized network, and even automate a few tasks. It also includes Host Guardian Hyper-V Support , which makes managing virtual machines much easier while keeping them secure.

They can help you manage the keys required to start a shielded VM. That said, the Datacenter edition is considered the most cost-effective yet scalable software-based data center solution out of all the Server editions.

To gain more insight on the features of the 2 editions, read this detailed Microsoft comparison post. Windows Server was the first Server version that offered the Essentials edition. This edition is designed for small organizations with preferably 25 to 50 devices in total. As the name implies, it includes the essential components a business needs to keep its company afloat.

This includes integration with Azure Site Recovery services that ensure business continuity in case of a disaster. The Essentials edition also supports integration with the Azure Virtual network to help you move your data to the cloud, which satisfies both business continuity planning and High Availability HA to all employees of the organization.

This edition is aimed at medium to large enterprises and was first launched with Windows Server However, it was discontinued after Server R2. The Enterprise Edition also comes in specialized variants for the x64 and Itanium architectures with support for much higher RAM capacity. The Foundation edition is preinstalled inside the OEM device, and a separate license for this edition cannot be purchased.

A single license can only work on a single device, thus it is only suitable for small businesses. That said, it is one of the cheapest server solutions for small business owners. However, this edition was only offered with Windows Server and R2 included but has since been discontinued.

The Foundation edition provides the core IT infrastructure needed to build a business, such as file and print sharing, remote access, and moderate security. It was the ideal OS for low-budget IT administrators to manage networks and domains at the time whilst providing basic organizational infrastructure. The Web edition of Windows Server began rolling out with Windows Server but was discontinued after and R2.

This means that Windows Server was the only version to offer both Web and a Foundation edition. The primary purpose of the Web edition is to host and build web applications, web pages, and XML services. Furthermore, other features are also somewhat restricted. For example, only 10 concurrent file-sharing connections are allowed at any moment.

The Advanced edition was only offered with Windows Server At the time, it was the only Server capable of handling added physical hardware. It was because of these capabilities, the Advanced edition of Server was ideal for medium to large organizations.

This edition cannot be purchased but can be subscribed to. Windows Server Datacenter: Azure edition is exactly like the regular Datacenter edition, but is available entirely on the Azure cloud infrastructure. It can be integrated with your on-premise servers, or entirely with your other cloud servers, or even as a hybrid server.

These are all the Server editions you may come across if you are working with Microsoft Servers. However, some of these editions may have further variations. While performing a clean Windows Server installation, apart from the editions, you will also be asked to choose whether you wish to install the Desktop Experience version or the regular one. The regular version is usually the Core version. Windows Server Core editions are missing the Graphical User Interface GUI you normally see on a Windows client machine, which includes the various windows, apps, the mouse cursor animations, etc.

It only includes the Command Line Interface CLI , thus only allowing you to configure and control the server using the scripts and commands. Download Now! Unlike Windows Server Essentials non-R2 , you can now run a single instance of a virtual machine. The server licensing rights have been expanded, allowing you to install an instance of Essentials on your physical server to run the Hyper-V role with none of the other roles and features of the Essentials Experience installed , and a second instance of Essentials as a virtual machine VM on that same server with all the Essentials Experience roles and features.

Definition of a socket is a CPU or physical processor. Logical cores are not counted as sockets. A single license of Standard and Datacenter edition covers up to two physical processors per physical server. Standard edition allows up to 2 virtual instances while the Datacenter edition allows unlimited number of virtual instances.

For example, a Windows Server R2 Standard edition installed on a physical server with one socket CPU can support up to two instances of virtual machines. These virtual machines can be Server R2 Standard or Essentials edition.

Similarly, if you install a Windows Server R2 Datacenter edition , then you can install an unlimited number of virtual machines. Scenario 2 : Install Server Standard Edition on a physical server with 1 physical processor, running 8 instances of virtual machines. A total of 50 users will be accessing the server. Remember that a single Standard edition license covers up to two physical processors and up to two instances of virtual machines. Since the requirement is to run 8 instances of virtual machines, we need four Standard edition licenses.

If we decided to use the Datacenter edition in this scenario, a single license with 50 CAL would be enough to cover our needs, because the Datacenter edition license supports an unlimited number of virtual instances and up to two physical processors.
