Непростые экономические условия, в которых вынужден существовать современный бизнес, вынуждают думать скорее не о развитии и расширении имеющейся ИТ-инфраструктуры, а о грамотном использовании базовых продуктов, без которых не обойтись. Одним из таких продуктов является Windows Server – популярная серверная операционная система, часто применяемая в крупных организациях. К сожалению, компании, относящиеся к малому и среднему бизнесу, от Windows Server часто отказываются, считая, что он:

• стоит дорого;
• предлагает слишком много всего ненужного.

Попробуем сегодня развеять эти заблуждения. Давайте вместе посмотрим, что из себя представляет Windows Server, и как его могут оптимально использовать небольшие организации.

Для чего нужен Windows Server 2012

Для начала поговорим о том, для чего нужен Windows Server.

В первую очередь это, конечно, построение единой инфраструктуры для организации любого размера. На основе такой инфраструктуры могут работать приложения различной сложности, разворачиваться дополнительные локальные и веб-службы.

Windows Server также успешно применяется для аутентификации и авторизации пользователей. Часто небольшие организации (от 25 ПК) отказываются использовать Windows Server, считая, что обойдутся ноутбуками, и никакое централизованное администрирование им ни к чему. А ведь здесь встает один из самых основных вопросов при управление компьютерными пользователями: предоставление доступа к конкретной информации. Безусловно, существуют случаи, когда организации нет нужды ограничивать доступ к информации (все живут в идеальном мире, никто ничего без спроса не правит, не удаляет, не передает конкурентам).

В реальности доступ к определенной информации все же нужно ограничивать (ну, как минимум, к бухгалтерской и финансовой отчетности). Второй момент: пользователю может понадобиться получить доступ к своим файлам с соседнего компьютера: чтобы их распечатать, показать руководству, представить потенциальным клиентам организации. Наконец, третье. Один из используемых компьютеров может просто выйти из строя. И если сам ноутбук заменить можно относительно безболезненно, то информация на нем может быть утеряна навсегда. Без Windows Server задачи аутентификации и авторизации пользователей, а также вопрос сохранения данных значительно затрудняется. Можно создавать рабочие группы, настраивать вручную все права. Но это занимает много времени. А потом всеми этими настройками очень сложно объективно и своевременно управлять.

Windows Server с помощью Active Directory, групповых политик и функции управления файлами позволяет в разы упростить эту задачу

Последняя версия

Последней версией на момент написания этой статьи является Windows Server 2012 R2. Несмотря на то, что система вышла в свет в октябре 2013 года, она не теряет своей актуальности.

По сравнению с предыдущими версиями, система претерпела ряд изменений для того, чтобы предоставить пользователям максимально востребованную функциональность. Среди основных нововведений представлено расширение возможностей виртуализации, хранение и обработки данных, репликации. Была расширена функция работы с сетевыми настройками, управление серверами и настройками автоматизации, повышены возможности обеспечения безопасности имеющейся инфраструктуры.

О том, какие функции были представлены в Windows Server 2012 R2, написано много статей, еще больше представлено материалов о том, как систему настраивать и эти функции использовать. Проблема заключается в применении знаний на практике. Причем дело не столько в технической настройке, сколько в необходимости выбора подходящей редакции Windows Server, которая будет максимально отвечать потребностям организации, и при этом не будет требовать лишней переплаты за ненужные возможности.

Есть еще один важный момент. Не обязательно приобретать самую дорогую редакцию Windows Server для того, чтобы настроить инфраструктуру своей сети. Вполне возможно, что вам подойдет более простая версия: получите весь нужный функционал и сможете сэкономить на лицензиях и внедрении. Поэтому основной вопрос, на который стоит обратить внимание – это редакции Windows Server и их лицензирование.

Лицензирование Windows Server 2012 R2

Windows Server 2012 R2 чаще всего предлагают приобрести в одной из двух редакций: Standard и Datacenter. Единственное их отличие заключается в том, что, имея лицензию Standard, можно бесплатно развернуть до двух виртуальных машин Windows. Если же вы приобрели лицензию Datacenter, то в количестве виртуальных машин, которые можно развернуть, вы не ограничены. При этом лицензирование Microsoft в редакциях Standard и Datacenter может потребовать дополнительных затрат.

С точки зрения правильного лицензирования необходимо также приобрести лицензии на клиентский доступ (Windows Server CAL) на количество пользователей (или устройств), которые в вашей организации используют компьютер. А если вы хотите предоставить своим сотрудникам возможность удаленного подключения к серверу, то необходимо также приобрести лицензии на удаленный доступ (Windows Server Remote Desktop CAL). Сумма набегает приличная. Особенно неприятно, когда не нужны даже те две виртуальные машины, которые позволяет без дополнительных лицензий стандарт.

Как итог, получаем значительные расходы на продукт, большая часть возможностей которого нам не нужны. В связи с этим обратите внимание на две редакции Windows Server 2012 R2, о которых рассказывают реже, но они намного привлекательнее для небольших организаций. Это редакции Windows Server 2012 R2 Foundation и Windows Server 2012 R2 Essentials.

Windows Server 2012 R2 Foundation

Windows Server 2012 R2 Essentials

Возвратимся теперь к одному из заблуждений, которое было обозначено в самом начале.

Очень часто небольшие компании не используют для администрирования сети именно серверную операционную систему из-за слишком высокой цены. Это справедливо, если вы выбираете между Windows Server Standard и Windows Server Datacenter. Их стоимость составляется из лицензии на сервер (в сервере не больше двух процессоров) плюс лицензии на клиентский доступ плюс лицензии на удаленное подключение. Такие затраты в большинстве случаев совершенно не вписываются в бюджет небольшой организации или стартапа, численность которых не превышает 25 пользователей.

Тем не менее, серверная система намного удобнее для реализации основных задач администрирования и управления системой, сетью, пользователями. Windows Server представлен в двух редакциях, которые отвечают этим требованиям – поддерживают необходимые функции и не бьют по бюджету: Windows Server Foundation и Windows Server Essentials.

Теперь, когда с лицензированием вопрос более или менее понятен, можно переходить к следующему шагу. А именно, решать, какие функции нам нужны, а какие нет. Это, например, касается такой функции, как Server Core – возможности устанавливать и использовать Windows Server в режиме консоли. Как показывает практика, такая возможность малым компаниям кажется слишком сложной.

А вот невозможность интеграции редакции Foundation с Office 365 может стать своеобразным камнем преткновения. В том случае, если интеграция с Office 365 критически важна, выбирать нужно Essentials.

Подводя итоги

Итак, Windows Server позволяет оптимизировать расходы на инфраструктуру. Широкий набор моделей лицензирования, а также вариантов приобретения лицензии позволяет подобрать тот вариант, который будет приносить организации пользу, при этом не переплачивать за неиспользуемые функции и ненужные нововведения.

Дешевые версии не означают, что они неприменимы в реальных условиях. Функциональность уменьшена обдуманно, при этом все нужные компоненты и даже некоторые встроенные дополнения присутствуют в редакции Foundation и Essentials. Пусть в Essentials нет роли Hyper-V; в то же время редакция поддерживает возможность интеграции с облачными приложениями и сервисами (Microsoft Azure и Office 365). Т.е. приобретая Essentials, вы получаете как качественно подготовленную инфраструктуру для вашей организации, так и возможность интеграции с ключевыми продуктами Microsoft, которые необходимы в повседневной современной работе – как на своем рабочем месте, так и удаленно.

В реальных рабочих условиях в каждой организации при построении инфраструктурных решений системные администраторы отдают предпочтения обкатанным и хорошо протестированным версиям. Поэтому Windows Server 2012 R2 своей актуальности еще долго не потеряет.

Disaster Recovery Rights

For each instance of eligible server software you run in a physical or virtual OSE on a licensed server, you may temporarily run a backup instance in a physical or virtual OSE on either (a) servers dedicated to disaster recovery and to your use, or (b) for instances of eligible software other than Windows Server, on Microsoft Azure Services, provided the backup instance is managed by Azure Site Recovery to Azure. The license terms for the software and the following limitations apply to your use of the backup instance.
The backup instance can run only during the following exception periods:
❖ For brief periods of disaster recovery testing within one week every 90 days.
❖ During a disaster, while the production server being recovered is down.
❖ Around the time of a disaster, for a brief period, to assist in the transfer between the primary production server and the disaster recovery server.
In order to use the software under disaster recovery rights, you must comply with the following terms:
❖ The OSE on the disaster recovery server must not be running at any other times except as above.
❖ The OSE on the disaster recovery server may not be in the same cluster as the production server.
❖ Other than backup instances running on Microsoft Azure Services, a Windows Server license is not required for the disaster recovery server if the Hyper-V role within Windows Server is used to replicate virtual OSEs from the production server at a primary site to a disaster recovery server.
❖ The disaster recovery server may be used only to run hardware virtualization software (such as Hyper-V), provide hardware virtualization services, run software agents to manage the hardware virtualization software, serve as a destination for replication, receive replicated virtual OSEs, test failover, and/or await failover of the virtual OSEs.
❖ Run disaster recovery workloads as described above.
❖ The disaster recovery server may not be used as a production server.
❖ Use of the software backup instance should comply with the license terms for the software.
❖ After the disaster recovery process is complete and the production server is recovered, the backup instance must not be running at any other times except those times allowed here.
❖ Maintain Software Assurance coverage for all CALs, External Connector licenses and Server Management Licenses under which you access the backup instance and manage the OSEs in which that software runs.
❖ Your right to run the backup instances ends when your Software Assurance coverage ends.
Your specific Software Assurance benefit eligibility can vary by Commercial Licensing program (such as an Enterprise Agreement or Open Value Agreement) and product, as well as the number of qualifying licenses you have enrolled in Software Assurance.

Volume Activation

A number of technologies are available in Windows Server 2012 R2 to simplify the task of configuring the distribution and management of an organization’s volume software licenses. These technologies include:
❖ The Volume Activation Services server role: Volume Activation Services is a server role in Windows Server 2012 (or later editions) that enables you to automate and simplify the issuance and management of Microsoft software volume licenses for a variety of scenarios and environments. With Volume Activation Services, you can install and configure the Key Management Service (KMS) and enable Active Directory-based Activation.
❖ Key Management Service (KMS): KMS is a role service that allows organizations to activate systems within their network from a server where a KMS host has been installed. With KMS, IT pros can complete activations on their local network, eliminating the need for individual computers to connect to Microsoft for product activation. KMS does not require a dedicated system, and it can be cohosted on a system that provides other services. By default, volume editions of Windows 8 (or later editions) and Windows Server 2012 (or later editions) connect to a system that hosts the KMS service to request activation. No action is required from the user.
❖ Active Directory-based Activation: Active Directory-based Activation is a role service that allows you to use Active Directory Domain Services (AD DS) to store activation objects, which can further simplify the task of maintaining volume activation services for a network. With Active Directory-based Activation, no additional host server is needed, and activation requests are processed during computer startup.
Any computers running Windows 8 (or later editions) and Windows Server 2012 (or later editions) with a Generic Volume License Key (GVLK) that are connected to the domain will activate automatically and transparently. They will stay activated as long as they remain members of the domain and maintain periodic contact with a domain controller. Activation takes place after the licensing service starts. When this service starts, the computer running Windows 8 (or later editions) and Windows Server 2012 (or later editions) RD contacts AD DS automatically, receives the activation object, and activates without user intervention.
Review this TechNet article for further details.

Frequently Asked Licensing Questions (FAQ)

1. How are Windows Server 2012 R2 Standard and Datacenter editions licensed?
   Windows Server 2012 R2 Standard and Datacenter editions will continue to have the same licensing model as Windows Server 2012 Standard and Datacenter editions. The editions are differentiated by virtualization rights only (two OSEs for Standard and unlimited OSEs for Datacenter). A single license covers up to two physical processors.
   Client Access Licenses (CALs) are required for each user or device accessed. The Windows Server 2012 related CALs provide entitlement to access and use Windows Server 2012 R2 functionality.
2. What is the difference between Windows Server 2012 R2 Standard edition and Windows Server 2012 R2 Datacenter edition?
   Both Standard and Datacenter editions provide the same set of features; the differentiator is the number of Virtual Operating System Environments (VOSE). A Standard edition license entitles up to two VOSEs on up to two processors (subject to the VOSE use rights outlined in the Product Terms document for Commercial Licensing or End User License Agreement for other channels). A Datacenter edition license entitles an unlimited number of VOSEs on up to two processors.
3. Will the Windows Server 2012 R2 and System Center 2012 R2 licensing models continue to be aligned?
   Yes. Both Windows Server 2012 R2 and System Center 2012 R2 have similar licensing structures. These include two editions: Standard and Datacenter.
   ❖ Single licenses that cover up to two physical processors.
   ❖ Editions differentiated by virtualization rights only (two for Standard; unlimited for Datacenter).
   (Client Access Licenses [CALs] will continue to be required for access to Windows Server 2012 R2 servers and management access licenses continue to be required for endpoints being managed by System Center.)
4. What are some of the features available in Windows Server 2012 R2 Datacenter and Standard editions?
   There are a variety of new features in Windows Server 2012 R2 Datacenter and Standard editions. Here are just a few examples:
   ❖ Enterprise-class virtual machine density, performance, and mobility with best-in-class performance and scale for Microsoft workloads
   ❖ High-performance file-based storage on cost-effective, industry-standard hardware with inbox storage virtualization and tiering
   ❖ Highly available, in-box hybrid networking for bridging physical and virtual networks in a multi-tenant environment and across premises
   ❖ Protection and recovery of assets for all your workloads with simple and affordable disaster recovery options
   ❖ Flexible remote access to corporate resources from virtually anywhere and on any device while helping protect corporate information
5. How do I determine which Windows Server 2012 R2 edition is right for me?
   Because there is feature parity between Windows Server 2012 R2 Standard and Datacenter editions, your decision will be based on your virtualization strategy; virtualization rights are the only differentiator between editions. If your strategy calls for a highly virtualized environment, Datacenter edition will provide you with optimum flexibility because it allows for unlimited virtualization. This edition allows you the elasticity to add and move virtual OSEs across Datacenter licensed servers without needing to track the virtual OSE count on that server. If you do not plan on a highly virtualized environment, Standard edition is the right product for your needs. If you purchase Standard edition today but find you need to expand the virtualization capacity of your licensed server, you can do one of the following:
   1. Purchase additional Standard edition licenses and assign them to the same physical server giving you the rights to run additional instances of Windows Server. The server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time.
   2. Purchase a Software Assurance Step-up license to Datacenter edition, changing the license to a higher edition that allows unlimited virtual OSEs. To use this benefit, your underlying license must have Software Assurance.
6. If I have a Windows Server 2012 R2 Standard edition license, how can I increase my virtualization rights?
   With the Windows Server 2012 R2 Standard edition licensing model, you can grow your virtualization environment by either buying a step-up license to Datacenter edition if you have Software Assurance, or by simply buying additional Standard edition licenses and assigning them to the same physical server. The server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time. For example, if you have a two-processor server and want to run a total of four VOSEs, you can purchase two Standard edition licenses and assign them to the same server. Additional examples are shown in the following table.

Картинка с сайта: www.the-chronic.eu

1. How do I calculate the number of licenses I need for a server?
   The number of licenses you will need depends on the number of physical processors on the server and the number of server instances that you will be running. (This applies only for Standard edition because Datacenter edition allows for unlimited VOSEs.) The larger of these two numbers determines the number of total licenses required.
   First, determine the number of physical processor licenses:
   Each license covers up to two physical processors, so to determine the number of licenses needed to fully license a physical server, just count the number of physical processors in the server and divide that number by two. This tells you the number of licenses that you will need. (Note: The number of cores on the physical processor is irrelevant.)
   Here are some examples:
   ❖ Two-processor server: 2 physical processors / 2 (number of processors covered by a license) equals 1. You will need one license to cover a two-processor server.
   ❖ Four-processor server: 4 physical processors / 2 (number of processors covered by a license) equals 2. You will need two licenses to cover a four-processor server.
   ❖ Eight-processor server: 8 physical processors / 2 (number of processors covered by a license) equals 4. You will need four licenses to cover an eight-processor server.
   Second, determine the number of virtual instances running:
   You can either count the number of VOSEs that are running and determine the number of Standard edition licenses (one license covers up to two VOSEs), or you can purchase Datacenter, which enables unlimited VOSEs on the server.
   Each Standard edition license provides you with the rights to run up to two VOSEs. To determine the number of Windows Server Standard edition licenses you need, count the total number of total VOSEs that you will run on the server; divide that number by two, and round up to the nearest whole number.
   After you determine the number of licenses needed to cover physical processors and/or VOSEs, the higher of those two numbers represents the total number of licenses required. Remember that the server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time
   For example, if you are running three virtual machines (VOSEs) on a two-processor server, you will require two licenses to cover the three virtual machines.
   If you assign two Standard edition licenses to a single server, you will be able to run a total of four VOSEs on that server. If you add additional Standard edition licenses to that server, the number of allowed VOSEs on that particular server will increase by two for a total of six VOSEs on that server.
2. Can I use one Standard license to cover a one-processor server?
   Yes. The Standard edition license will allow you to license up to two physical processors on a single server; however, it does not require the server to have two physical processors.
3. Can I split my Windows Server 2012 R2 license across multiple servers?
   No. Each license can be assigned only to a single physical server.
4. Can I assign a Windows Server 2012 R2 license to a virtual machine?
   No. A license is assigned to the physical server. Each license will cover up to two physical processors. After assigning the license(s) to a physical server, you now have the rights to use the VOSE on that server.
5. Can I mix Datacenter and Standard licenses on the same server?
   No. All of the processors on a given server must be licensed with the same version and edition. You can run different editions or older versions of Windows Server software as guests within VOSEs, but you are not allowed to assign multiple licenses of different versions or editions to the same physical server to license the processors on the server.
6. If I want to use the software from an earlier Windows Server version or edition, what are my options?
   If you have Windows Server 2012 R2 Datacenter edition, you have the right to downgrade software bits to any prior version or lower edition. If you have Windows Server 2012 R2 Standard edition, you have the right to downgrade the software to use any prior version of Enterprise, Standard, or Essentials editions.
   The ability to downgrade does not change the licensing or support terms in which you can use the product; the purchased product (Windows Server 2012 R2) rights apply. This means that the license will continue to cover two physical processors, and the virtualization rights do not change. In addition, the Client Access License (CAL) corresponding to the purchased version will apply, as an exception; if you are running a previous version of one of the eligible downgrades, you can use the corresponding CAL version if one exists. Here are a few examples.

1. If I have Software Assurance in place at the time that Windows Server 2012 R2 is generally available, will my grant be reflected in my licensing records?
   Yes. You will see your grant in the Volume Licensing Service Center (VLSC) in addition to immediately being able to use the new product and own the perpetual rights (based on your underlying license) to the edition of Windows Server 2012 R2 that you are entitled to receive.
2. If I have Datacenter edition with Software Assurance when Windows Server 2012 R2 is released, which edition will I be entitled to use?
   If you have Software Assurance on Datacenter edition, you will be entitled to Windows Server 2012 R2 Datacenter edition. For every Windows Server 2012 Datacenter license with Software Assurance, you will receive one Windows Server 2012 R2 Datacenter edition license.
3. If I have Standard edition with Software Assurance when Windows Server 2012 R2 is released, which edition will I be entitled to receive?
   If you have Software Assurance on Standard edition, you will be entitled to Windows Server 2012 R2 Standard edition. For every Windows Server 2012 Standard license with Software Assurance, you will receive one Windows Server 2012 R2 Standard edition license.
4. What are my Software Assurance migration rights by Microsoft purchase program?

1. How much will Windows Server 2012 R2 Standard and Datacenter editions cost?
   Pricing levels vary. For your specific pricing, contact your Microsoft reseller. Microsoft does not determine pricing or payment terms for licenses acquired through resellers. Windows Server Edition Commercial Licensing Open No
2. Why is the price of Windows Server Datacenter 2012 R2 changing?
   Microsoft takes pricing and licensing decisions very seriously. All pricing decisions take into account changing product value, customer and partner feedback, and market conditions. Windows Server Datacenter edition is optimized for highly virtualized environments and includes unlimited virtualization rights. This provides flexibility to add and move virtual OSEs across licensed servers without needing to track the virtual OSE counts on your servers.
   Over the past few releases, Windows Server has added in a tremendous amount of new features and enhancements, as well as significant performance and capacity improvements, to support highly virtualized datacenter and cloud environments. A few of these examples include:
   High-scale performance enhancements, including support for:
   ❖ 320 logical processors on hardware
   ❖ 4 TB physical memory
   ❖ 64 virtual processors per virtual machine
   ❖ 1 TB memory per virtual machine
   ❖ 1,024 active virtual machines per host
   ❖ Live migration enhancements including cross-version live migration, live migration compression, and live migration with RDMA.
   ❖ The ability to grow or shrink VHDXs with no downtime.
   ❖Hyper-V Replica enhancements, including tertiary site support and sync intervals as low as 30 seconds.
   And much more.
   On servers that are not expected to be highly virtualized, Windows Server Standard is optimal, providing two instances per license, with an ability to assign multiple licenses to a single server to increase the allowed virtual OSE densities on that server. Keep in mind that servers licensed with Windows Server Standard will need to have the appropriate number of licenses assigned to that server to ensure coverage of all of the virtual OSEs that are running at any given time.
3. Which Client Access Licenses (CALs) do I use to access Windows Server 2012 R2?
   Your Windows Server 2012 Client Access License (CAL) is used to access Windows Server 2012 and Windows Server 2012 R2. You do not need to have Software Assurance on your Windows Server 2012 CAL in order to use it to access Windows Server 2012 R2.
4. Do I still need a separate CAL to access Remote Desktop Services (RDS) and Active Directory Rights Management Service (ADRMS)?
   Yes. The licensing requirements for Remote Desktop Services (RDS) and Active Directory Rights Management Service (ADRMS) have not changed with Windows Server 2012 R2. Customers are still required to purchase an ADRMS and/or RDS CAL in addition to a Windows Server CAL to access ADRMS and/or RDS functionality, respectively.

6. Can I move Windows Server 2012 R2 licenses and images between Hyper-V and Azure?
   Windows Server 2012 R2 licenses, just like Windows Server 2012, are not eligible for the License Mobility through Software Assurance benefit. You can continue to take advantage of the license mobility rights for other server applications; however, Windows Server will continue to be purchased separately from the service provider or Azure.

8. How do I license Windows Server 2012 R2 on Core Infrastructure Suite to run some instances on Azure?
   You are not able to run your Core Infrastructure Suite (CIS) Windows Server license in Azure because Windows Server does not offer mobility right as a standalone license or as a component product within the Core Infrastructure Suite product purchased.
9. Are there any changes to the licensing model for Windows Server 2012 R2 Essentials?
   Windows Server 2012 R2 Essentials will continue to have a license that covers a single server with up to two physical processors. It does not require CALs, but is limited to 25 user accounts.
   With previous versions of the Windows Server Essentials edition, it was necessary to obtain a hypervisor separately in order to run as a virtual machine—options included the free Microsoft Hyper-V Server or using Windows Server Standard edition to run Hyper-V. With Windows Server 2012 R2 Essentials, the product licensing terms have been expanded to enable you to run one operating system instance on the physical server for Hyper-V, plus a second Operating System Environment on that server in order to run Essentials as a virtual machine. Installation wizards have also been created to simplify the process of deploying as a virtual machine by automating the steps necessary to set up and configure the host server environment. This makes it easier than ever before to take advantage of Hyper-V and its features, such as Live Migration and Hyper-V Replica.
10. What are some of the features that are now available in Windows Server 2012 R2 Essentials?

    ❖ Protect your data
    ❖ Provide secure remote access
    ❖ Integrate cloud services
    Customers can use Windows Server 2012 R2 Essentials as a platform to run critical line-of-business applications and other on-premises workloads. It can also provide an integrated management experience when running cloud-based applications and services, such as email, collaboration, online backup, and more.
11. What are the different editions available with Windows Server 2012 R2 Essentials?
    There is only one edition: Windows Server 2012 R2 Essentials. It is a flexible offering that provides a platform for running on-premises or cloud-based workloads.
12. How much will Windows Server Essentials cost?
