Securing modernized apps and simplified networking on Windows with Calico
Containers have become synonymous with application modernization, and Kubernetes has become the leading solution for orchestrating containerized applications. With Windows Server version 1709, Windows now has parity with Linux for Kubernetes networking from a platform perspective.
Ask Microsoft Anything: Windows Server Containers
Containers are redefining the way we build and operate reliable systems in the cloud by providing a way to wrap up an application in its own isolated box. For the application in its container, it has no knowledge of any other applications or processes that exist outside of its box. Everything the application depends on

Рады сообщить, что Windows Server, версия 1709 доступен в облаке Azure Pack Infrastructure для всех пользователей.
В честь этого радостного события дарим скидку 25% для новых пользователей облака Azure Pack Infrastructure до конца 2017 года.
Как зарегистрироваться и получить скидку 25%
Для получения доступа, консультации или запроса коммерческого предложения заполните форму. Для получения скидки в поле «комментарии» укажите «Хочу скидку 25% за инновации».
Описание облака можно скачать тут.
Стоимость облачной инфраструктуры можно расчитать на официальном калькуляторе. Вам не нужно волноваться о лицензировании Windows Server, оплате за количество лицензируемых ядер, Software Assurance (без которого не получить Windows Server 1709) – для вас уже доступны в облаке актуальные лицензионные ОС редакций Datacenter без дополнительной оплаты.
Необходимые вам серверы будут предсозданы, достаточно использовать данные из приветственного письма для подключения. Тем не менее если требуется создать серверы самостоятельно, можно воспользоваться руководством либо статьей о создании сети и сервера.
Подходит даже для минимального объема ресурсов в облаке
Мы ожидаем, что Windows Server версия 1709 будет активно использоваться для размещения современных приложений и сервисов в нашем облаке, в том числе сайтов на ASP.NET Core 2 и SQL Server 2017, в качестве надежных хранилищ данных и для запуска контейнеров.
Даже на минимально возможной облачной подписке с 1 vCore, 2 GB Ram, 25 GB Storage, 1 IPv4, 2 vLAN, 2 Site-To-Site VPN вы сможете воспользоваться Windows Server версия 1709.
Новый цикл релизов Windows Server
Windows Server, версия 1709 – первая ОС от Microsoft с циклом выпуска новых версий раз в 6 месяцев (Semi-Annual Channel, SAC) для наиболее оперативного внедрения новой функциональности, требуемой современным программным системам в постоянно изменяющемся мире. Срок поддержки каждой версии этой ОС — 18 месяцев. Windows Server 1709 доступен только в облаках и при наличии подписки Software Assurance. Покупка каждой новой версии ОС не требуется — и в облаках и в software assurance заказчик платит за подписку и пользуется актуальной ОС.
Windows Server 2016 отстается последней актуальной ОС в канале Long-Term Servicing Channel, LTSC с циклом выпуска новых версий раз в 2-3 года и сроком поддержки 5 лет обычной поддержки и 5 лет расширенной.
В этом цикле релизов у ОС опционально может быть установлен графический интерфейс.
Когда используется быстрый цикл релизов, в названии используется слово «версия». Таким образом правильно говорить: Windows Server, версия 1709, но Windows Server 2016.
Что нового в Windows Server
Полный список изменений доступен на Technet.
Некоторые улучшения, актуальные для пользователей облака:
- Контейнеры Server Core стали занимать на 60% места меньше.
- Контейнеры Nano Server – на 80% места меньше (ранее — 390 Мб., теперь — 80 Мб.)
- Добавлена поддержка Linux–контейнеров с Hyper-V изоляцией.
Nano Server больше не может быть хостом — теперь эта ОС предназначена только для использования в контейнерах.
Для управления сервером через веб-интерфейс можно использовать Project Honolulu, рассмотренный нами в прошлой статье.
Варианта использования с графическим интерфейсом нет для максимальной производительности и безопасности.
В Windows Server версии 1709 больше не предустанавливается клиент и сервер SMB1, возможность гостевой аутентификации в SMB2 и более поздних версиях выключена по-умолчанию.
Редакция Essentials больше не доступна, только Standard и Datacenter (у нас в облаке все Windows Server редакции Datacenter).
Появилась возможность смены домена без перестроения кластера, что крайне полезно, когда вы сначала строите песочницу, настраиваете, а затем переключаете ее на продакшн.
Теперь есть возможность объединения кластеров в группы (cluster set) для упрощения администрирования и использования. Объединение кластеров может включать в себя слабо-связанные кластеры с разными вычислительными узлами, узлами хранения или гиперконвергентные кластеры. Это позволит облачному провайдеру например мигрировать VM автоматически между разными кластерами, например с HDD, SSD, NVME, Storage Class Memory (SCM), разными типами CPU, GPU, позволит снять ограничения на размер кластера и масштабировать облако до тысяч хост-серверов, настраивать зоны доступности (как в глобальном Azure).
Больше не нужно выбирать между современной файловой системой и дедупликацией данных — она поддерживается и на ReFS, позволяя сэкономить до 95% места на диске.
Remote Desktop Services теперь может быть интегрирован с Azure AD: благодаря интеграции пользователи могут использовать единые политики, многофакторный вход, интегрированную аутентификацию с другими SaaS приложениями.
Улучшения в контейнеризации
Поддержка docker routing mesh — возможности публикации портов сервисов за пределы swarm–кластера.
Возможность запуска Linux–контейнеров на Windows. Для запуска Linux–контейнеров используется проект LinuxKit.
Возможность подключения SMB как диска к контейнерам. В Windows Server версии 1709 можно назначить SMB–шару как диск с буквой в контейнер.
Заключение
Надеемся, что оперативное внедрение новых технологий в облако Azure Pack Infrastructure поможет вашим проектам развиваться быстрее и опережать конкурентов. Новая ОС очень быстрая и эффективная, что позволит вам использовать меньше ресурсов в облаке и платить меньше.
Успехов!
Microsoft just released the new Windows Server version 1709 in the Semi-Annual Channel. This blog post is for beginners which want to do their first step setting up Windows Server Core.
First you boot your server or virtual machine form the Windows Server 1709 ISO file. and select which Operating System you want to install. You can choose between Windows Server Standard or Windows Server Datacenter. As you might see, there is only Server Core available. The Server with Desktop Experience or Full Server is only available in the LTSC (Long-Term Servicing Channel) in Windows Server 2016.
After accepting the license terms, you can choose the installation type. Even there is an upgrade option, you should choose Custom which will be a new install. Since an in-place upgrade from older Windows Server versions is not supported.
Choose which drive you want to install and the partitioning you want to use
After that Windows Server will install itself, and reboot for a couple of times.
After the installation is finished you have to set the default Administrator password.
When you login for the first time, it runs the Windows command prompt with the common Windows commands, or you can run PowerShell, or if you need the magic key to the server core configuration you can run “sconfig” which allows you quickly to do configuration changes, install updates and more.

Starting 17th October, Microsoft has released a new build of Windows Server, called with name RS3 (Red Stone 3), in the same moment of new build of Windows 10. The content in this section describes what’s new and changed in Windows Server and what is the new roadmap for the operating system.
Naming
The name of this build is just Windows Server, plus the build version. So for this release the official name is Windows Server version 1709. Windows Server 2016 is the name of classic release, classified as LTSC, available via OEM and retail channels.
Semi-Annual Channel
As Windows 10, that receive a new release every 6 months, also Windows Server adopt the same business method with some small differences. The goal is very easy: offer an operating system that follow the new requirements and the new challenges without force companies to wait 3 years; don’t forget that Microsoft Azure is based on Windows Server and this means that the platform must be faster to grow-up without spend a double time for management and maintenance. Figure 1 show what’s new for SAC and is we can see that the product is available only via Software Assurance, that is not present a User Interface and that the support is guarantee only for 18 months from the released date.
Figure 1 – SAC vs LTSC
Windows Server 2016 is the official build to do many stuffs, classified as Long Term with the full User Interface and with a support guarantee for 5 years + 5 years with the option to have other 6 years with the Premium Assurance (available for Windows Server and SQL Server).
Figure 2 show the roadmap about next releases and is not required a genius to immaginate that the next LTSC build will be released in October 2018 (Windows Server 2019?).
Figure 2 – Roadmap
The Scope of v1709
If you think that Windows Server 1709 is for everyone, you wrong. Microsoft was very clear about the final scope of this build: container…or if you prefer, Docker. Use v1709 for other scope is not impossible but is a little bit forced because we will see soon that the build has been limited in some features.
Upgrade In-Place?
Do you have a virtual machine with IIS installed and the plan is upgrade to v1709? No way! Upgrade in-place is not possible and supported, this means that you must the OS from beginning. Don’t forget that the build is available only as Server Core so the management is via cmd or PowerShell.
No Storage Spaces Direct
One of the “cut” into v1709 is Storage Spaces Direct (S2D) that is disabled by design; in case you try to enable the role, will receive a message error like “The requested operation is not supported“; it is also not supported to introduce servers running Windows Server, version 1709 into a Windows Server 2016 Storage Spaces Direct deployment. So, if you have this requirement or you adopt the Hyperconverged model, Windows Server 2016 is the only way.
For your information, Storage Spaces Direct will be reintroduced into RS4, planned for March 2018.
Bye Bye Nano Server
Another “cut” into this new build is the retargeting for Nano Server. With Windows Server 2016, this SKU was redirected for virtualization environment and container world, thanks a small footprint and a faster deployment speed. It seems that the SKU did not like this much to the public, so Microsoft has decided to remove Nano Server for all the roles expect for Docker.
The result of this optimization is a reduced size: from 1GB, in Windows Server 2016, to 200MB in Windows Server v1709. If you have deployed Nano Server for some roles, like File Server, could be better plan a migration because in this moment is not planned an upgrade.
Windows Subsystem for Linux
I’ve already spoke in this article about this topic (Windows Server RS3: Configure Windows Subsystem for Linux), but also Windows Server has the possibility to use Linux kernel in few steps thanks to Windows Subsystem for Linux.
Docker Power!
As I said, Docker is the main focus of this build and the majority of investment are around container world. These are the improvements:
- Support for Linux container!
- Support for volume into SMB share
- Support for Routing Mesh (perfect for Docker Swarm)
- Support for Named pipes
- Support for Kubernetes
- Nano Server and Windows Server Core images optimized (up to 80%)
Hyper-V Improvements
Also Hyper-V has received few new features:
- Support for Shielded VM Linux
- Virtualized Persistent Memory (vPMEM)
- Virtual Network Encryption – new feature that provides the ability for the virtual network traffic to be encrypted between through Datagram Transport Layer Security
Virtualized Persistent Memory
The Persistent Memory is a new technology based on NVDIMM-N, available on last servers, that allows to have a Storage Class Memory (SCM), technology that combines flash storage and DRAM on the same memory module, enabling extraordinary performance improvement. Each NVDIMM-N provides a nonvolatile memory and resides in a standard CPU memory slot, placing data close the processor; NVDIMM-N takes full advantage of the high bandwidth and extremely low latency that is characteristic of the memory bus. Data access time is around 150ns for NVDIMM-N compared with 60000ns of NVMe disks.
Persistent Memory is supported in Windows Server 2016, where can be used as cache into S2D scenario, Red Hat Enterprise 7.3 and soon in VMware.
In Windows Server v1709, Hyper-V extend this feature inside virtual machines (Virtualized Persistent Memory) and this means use this incredibly power for many workloads. Virtualized Persistent Memory is enabled by creating a VHD file (.vhdpmem) on a direct access volume on a host. In this moment there are some limitations about vPMEM like the impossibility to migrate the VM, snapshot are not supported and the entire management can be done only via PowerShell.
Data Deduplication
You no longer must choose between the advantages of a modern file system with ReFS and the Data Deduplication (available only in NTFS): now, you can enable Data Deduplication wherever you can enable ReFS.
Management
This is not linked directly with last 1709 but one of the main goal for Microsoft is evolve the server management and reduce all the obsolete consoles. The solution is called Project Honolulu (Welcome to Honolulu: the New Server Management Experience Era), the next generation tooling with a simplified, integrated, secure, and extensible interface based on HTML5.
Conclusion
As we see, Windows Server version 1709 is the evolution of Windows Server 2016 but not for everyone. If you are working with Docker and container, this is the right build for you but if it’s not….wait the RS4 or the vNext LTSC.

Windows Server, version 1709 is the first Semi-Annual Channel release of the Windows Server operating system family, released on 17 October 2017. It introduces the then-newly-established Semi-Annual Channel (SAC), intended to support containerized workloads and micro-service applications while retaining a frequent, periodic servicing release schedule for every half-year. Unlike Long-Term Servicing Channel (LTSC) releases, SAC releases are only available in the form of a Server Core installation type, and cannot be upgraded to from an existing LTSC release, such as Windows Server 2016.
Semi-Annual Channel releases typically came with 18 months of mainstream support, and were commercially distributed to volume-licensed customers via the Microsoft Software Assurance program and on the Microsoft Azure marketplace. Developers were also able to obtain a Windows Server SAC release for development and testing purposes through an applicable Visual Studio subscription.
The Semi-Annual Channel was deprecated as part of Windows Server 2022’s release; it was superseded by the newer Annual Channel (AC) introduced as part of Windows Server, version 23H2, which had similar if not identical goals to SAC releases.
