Extended Security Updates for SQL Server and Windows Server 2008 and 2008 R2 on Azure Stack

Extended Security Updates for SQL Server and Windows Server 2008 and 2008 R2 on Azure Stack

Posted in Cloud, Microsoft, Microsoft Azure, Microsoft Azure Stack, PowerShell, SQL Server, Virtualization, Windows Server, Windows Server 2008, Windows Server 2008 R2, Windows Server 2019, Work

SQL Server and Windows Server 2008 and 2008 R2 will both be out of extended support within the  next 12 months (detailed dates below). This means if you have these versions, you’ll need to migrate to newer versions of SQL Server or Windows Server or buy Extended Support soon to maintain support and receive security updates and fixes. Buying Extended Support is not cheap. Customers with active Software Assurance or subscription licenses can purchase Extended Security Updates annually for 75 percent of the full license cost of the latest version of SQL Server or Windows Server. A lot of customer should start migrating to newer versions of these products to avoid these extra costs.

Extended Support dates

  • Extended Support for SQL Server 2008 and 2008 R2 will end on July 9, 2019.
  • Extended Support for Windows Server 2008 and 2008 R2 will end on January 14, 2020.

However, in mid-2018 Microsoft announced a new option for SQL Server 2008 and Windows Server 2008 End of Support. Customers running 2008 or 2008 R2 versions of SQL Server and Windows Server in Azure virtual machines will get Extended Security Updates for free. This will give customers some extra time to migrate to newer versions of SQL Server and Windows Server. Or even better, to Azure PaaS and serverless computing like Azure Functions.

The great thing about this, is that you can also combine this with your Azure Hybrid benefits, to use your SQL Server and Windows Server on Azure with your on-premise licenses.

Extended Security Updates on Azure Stack

If you are thinking to migrate to the cloud, this new option will bring down costs for you. However, not everyone is fully ready to move all their servers to the public cloud. You might still need or want to run some servers on-premise in your datacenter. This will leave you with buying Extended Support or what a lot of people don’t know, you can also run your SQL Server and Windows Server 2008 and 2008 R2 on Azure Stack and get Extended Security Updates for free, since it is basically Azure!

This is great, especially since Azure Stack also comes with great IaaS capabilities. And if you are thinking about using Azure in the mid-term, Azure Stack provides you with Azure capabilities, but still allows you to stay in your own datacenter.

Azure Stack VM Update Management

Using Azure Update Management on Azure Stack

Posted in Cloud, Microsoft, Microsoft Azure, Microsoft Azure Stack, Virtualization, Windows, Windows Admin Center, Windows Server, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019

At Microsoft Ignite 2018, Microsoft announced the integration of Azure Update and Configuration Management on Azure Stack. This is a perfect example how Azure services from the public cloud can be extended into your datacenter using Azure Stack. Azure Update and Configuration Management brings Azure Update Management, Change Tracking and Inventory to your Azure Stack VMs. In the case of Azure Stack, the backend services and orchestrator like Azure Automation and Log Analytics, will remain to run in Azure, but it lets you connect your VMs running on Azure Stack.

Azure Update and Configuration Managemen Schemat

Today, the Azure Update and Configuration Management extension, gives you the following features:

  • Update Management – With the Update Management solution, you can quickly assess the status of available updates on all agent computers and manage the process of installing required updates for these Windows VMs.
  • Change Tracking – Changes to installed software, Windows services, Windows registry, and files on the monitored servers are sent to the Log Analytics service in the cloud for processing. Logic is applied to the received data and the cloud service records the data. By using the information on the Change Tracking dashboard, you can easily see the changes that were made in your server infrastructure.
  • Inventory – The Inventory tracking for an Azure Stack Windows virtual machine provides a browser-based user interface for setting up and configuring inventory collection.

If you want to use Azure Update Management and more on VMs on-premise (without Azure Stack) or running at another Cloud Provider, you can do this as well. Have a look at Windows Admin Center, which allows you to directly integrate with Azure Update Management. However, there will be a difference in pricing.

System Center release cadence

System Center 2019 – What’s new

Posted in Cloud, Hyper-V, Microsoft, Microsoft Azure, Service Management Automation, Service Manager, System Center, Virtual Machine Manager, Virtualization, Windows Admin Center, Windows Server, Windows Server 2019, Work

Microsoft just launched Windows Server 2019 and Windows Admin Center, which also raised the interest in System Center 2019. At Microsoft Ignite, Microsoft was talking about what is new in System Center 2019, the future of System Center, and how it fits in with Windows Admin Center and other management tools.

Microsoft Cloud and Datacenter Management Story

Microsoft Cloud and Datacenter Management Overview

With Microsoft now offering a range of products to manage your Cloud and Datacenter environments, the question comes up “which is the best solution?”. It is not only depending on the size of your company, it also depends on which services you are using and what your job role is. Coming from the Azure site, you have Azure Security and Management, which allows you not only to manage your Azure resources but also integrates and extends with your on-premises environment. System Center is aimed to manage fatacenter environments at scale, and Windows Admin Center helps you to dig deeper to manage individual servers or single cluster management. Both Windows Admin Center and System Center 2019, can be used side by side and both are integrated into Microsoft Azure.

System Center Windows Admin Center better together

System Center vs Windows Admin Center

I often get the question, does Windows Admin Center replace System Center? The answer to this is no, System Center is aimed to do management at a datacenter scale, while Windows Admin Center is giving you deep management access to a single server or clusters. In small environments you might end up using Windows Admin Center only, but in larger datacenter deployments, you are likely to use a combination of System Center and Windows Admin Center.

System Center 2019 Suite Improvements

System Center 2019 Focus

The System Center 2019 release focuses on three main areas. First of all, it adds more capabilities to the existing components and features which were requested by customers. Secondly, it brings integration for the next version of Windows Server, Windows Server 2019 and brings new Windows Server features to life in System Center. Last but not least, System Center 2019 adds more Hybrid Cloud integrations with Microsoft Azure.

Azure Live Migration

Azure uses Live Migration for VMs

Posted in Cloud, Hyper-V, Microsoft, Microsoft Azure, Virtualization, Windows Server, Work

If you have worked with Azure in the past, you might have been aware that Azure didn’t have live migration for VMs hosted in Azure for a long time. This had an impact for customers in terms of VM up-time during host maintenance. You basically got emails, that the host your VMs were running is going into maintenance during a specific time, and you will have a possible outage. Microsoft Hyper-V, which is the Hypervisor in Azure, had Live Migration for a long time. Today, Microsoft revealed that they are using Live Migration in Azure since early 2018 to move virtual machines in cases of rack maintenance and software and BIOS updates, as well as hardware faults.

But Microsoft didn’t stop there, they made even better using Machine Learning. Predictive ML helps Microsoft to detect proactively failure and do failure predictions. And in case a hardware failure is predicted, Microsoft can move the virtual machines from that host without downtime, using live migration.

To further push the envelope on live migration, we knew we needed to look at the proactive use of these capabilities, based on good predictive signals. Using our deep fleet telemetry, we enabled machine learning (ML)-based failure predictions and tied them to automatic live migration for several hardware failure cases, including disk failures, IO latency, and CPU frequency anomalies.

 

We partnered with Microsoft Research (MSR) on building our ML models that predict failures with a high degree of accuracy before they occur. As a result, we’re able to live migrate workloads off “at-risk” machines before they ever show any signs of failing. This means VMs running on Azure can be more reliable than the underlying hardware.

Microsoft talks in a blog post more about Live Migration in Azure and goes more in details about the challenges and how live migration in Azure works. It is great to see Microsoft adding features to improve VM resiliency with features like live migration and machine learning technology.

Intel NUC Windows Server

Building a Windows Server Lab with an Intel NUC

Posted in Cisco, Cloud, Hardware, Hyper-V, Microsoft, Microsoft Azure, Private Cloud, Server, UCS, Virtualization, Windows, Windows Admin Center, Windows Server, Windows Server 2019, Work

With the release of Windows Server 2019, which includes a ton of Hybrid Cloud integration features, it was time to build a new lab environment. The plan is to create a lab and demo environment for my presentations and workshops. Until today, I was still using my hardware from 2011, which was built from Cisco C200 and HPE ProLiant servers. This was, more or less, datacenter grade hardware, it was using a lot of electricity and made a lot of noise. Not really the thing for a home lab on your desk. With some pretty good deals out there, I decided to buy a brand-new Intel NUC. NUC stands for Next Unit of Computing, which is a small, light, cheap and not very noisy computer, which gives you the latest Intel CPUs and ports. Mostly used as desktop or media computers. However, the price and the features, are also making it a great option for a lab running Hyper-V.

If I look at the hardware our customers are using today, there is not really a good way to build a cheap home lab based on datacenter hardware. And with my workloads mostly running in Azure anyway, the Intel NUC seems to be a great option. For most of my demos a single server running Hyper-V should be enough. For demos on Storage Spaces Direct or Clustering I can still use Azure with Nested Virtualization.

Intel NUC Windows Server LAB

I decided to get an Intel NUC NUC8i7BEH – Bean Canyon with the following specs:

  • Intel Core i7-8559U
  • 32GB DDR4 RAM
  • 1TB M.2 Samsung 970 EVO
  • Intel Wireless-AC 9560 + Bluetooth 5.0
  • Gigabit LAN
  • USB-A and USB-C ports
  • Thunderbolt 3 port

Unfortunately, the Intel NUC is limited to 32GB of RAM and this version does not have a TPM chip. The good thing, it runs Windows Server 2019 and Windows Admin Center just fine. So far I don’t have any issues, except that there are some missing drivers for Windows Server 2019. We will see how it works out in the next couple of months.

Let me know if you have any questions in the comments.

Remove All Docker Container Images

New Windows Server 2019 Container Images

Posted in Cloud, Containers, Docker, Hyper-V, Kubernetes, Microsoft, Microsoft Azure, Nano Server, Server Core, Virtualization, Windows, Windows 10, Windows Server, Windows Server 2016, Windows Server 2019, Work

Microsoft today released the new Windows Server 2019 again. After they quickly released Windows Server 2019 during Microsoft Ignite, they removed the builds again, after some quality issues. However, today Microsoft made the Windows Server 2019 builds available again. Microsoft also released new Windows Server 2019 Container Images for Windows, Windows Server Core and Nano Server.

Download Windows Server 2019 Container Images

You can get them from the new Microsoft Container Registry (MCR).

Microsoft was hosting their container images on Docker Hub until they switch to MCR (Microsoft Container Registry). This is now the source for all Windows Container Images like Windows Server 2019, Windows Server 2016 and all the Semi-Annual Channel releases like Windows Server, version 1709 or Windows Server, version 1803.

Download the Windows Server 2019 Semi-Annual Channel Container Images (Windows Server, version 1809). This includes also the new Windows Container Image.

The Windows Server Core Image is also available as a Long-Term Servicing Channel Image:

However, if you want to browse through container images, Docker Hub continues to be the right place to discover container images. Steve Lasker wrote a blog post about how Microsoft syndicates the container catalog and why.

Download Windows Server 2016 and Windows Server SAC Container Images

Also the existing Windows Server 2016 and Windows Server, version 1803 and Windows Server 1709 container images moved to the Microsoft Container Registry (MCR).

You should also make sure to update your Dockerfile references:

Old Windows Server Dockerfile reference

FROM microsoft/windowsservercore:ltsc2016

New Windows Server Dockerfile reference

FROM mcr.microsoft.com/windows/servercore:ltsc2016

Removing the “latest” tag from Windows Images

Starting 2019, Microsoft is also deprecating the “latest” tag for their container images.

We strongly encourage you to instead declare the specific container tag you’d like to run in production. The ‘latest’ tag is the opposite of specific; it doesn’t tell the user anything about what version the container actually is apart from the image name. You can read more about version compatibility and selecting the appropriate tag on our container docs.

Removing Container Images

Remove All Docker Container Images

If you want to remove existing container images from your PC, you can run docker rmi to remove a specific image. You can also remove all containers and container images with the following commands:
