With the introduction of private endpoint support, users can now access Elastic SAN volumes either through private endpoints or via public endpoints that are restricted to specific virtual network subnets. This update is crucial for those who need the added layer of security that private endpoints provide. Additionally, the shared volume support allows users to connect and utilize an Elastic SAN volume from multiple compute clients, such as virtual machines. This is done while using SCSI reservation commands to select from various supported access modes to read or write to the volume. Furthermore, persistent reservations are supported, ensuring uninterrupted access to data even across reboots.

For a deeper understanding and more details on these features, you can read the blog and refer to the documentation about Azure Elastic SAN.

Hotpatching in Windows Server: a revolution in virtual machine management

In the digital age, ensuring business continuity is essential, no longer just an added value. For many companies, frequent interruptions, even of short duration, are unacceptable for their critical workloads. However, ensuring that continuity can be complex, whereas the management of virtual machines (VM) with Windows Server operating system is in some respects complex, especially in relation to applying security patches and updates. With the advent of the hotpatching feature from Microsoft, a new chapter in VM management has opened: a more efficient approach that minimizes disruption, guaranteeing servers that are always up-to-date and protected. This article looks at the features and benefits of this innovative solution.

What is Hotpatching?

Hotpatching, introduced by Microsoft, is an advanced technique that allows you to update Windows Server operating systems without the need to restart. Imagine you can “change tires” of your moving car without having to stop it. This is the "magic" of hotpatching.

Where you can use Hotpatching

Hotpatch functionality is supported on “Windows Server 2022 Datacenter: Azure Edition”, that you can use it for VMs running in Azure and Azure Stack HCI environment.

The Azure images available for this feature are:

Windows Server 2022 Datacenter: Azure Edition Hotpatch (Desktop Experience)
Windows Server 2022 Datacenter: Azure Edition Core

Note that Hotpatch is enabled by default on Server Core images and that Microsoft recently extended hotpatching support to include Windows Server with Desktop Experience, further expanding the scope of this feature.

Updates supported

Hotpatch covers Windows security updates and maintains an alignment with the content of security updates issued in the regular Windows update channel (non hotpatch).

There are some important considerations for running a Windows Server Azure Edition VM with hotpatch enabled:

reboots are still required to install updates that are not included in the hotpatch program;
reboots are also required periodically after a new baseline has been installed;
reboots keep the VM in sync with non-security patches included in the latest cumulative update.

Patches not currently included in the hotpatch program include non-security updates released for Windows, .NET updates and non-Windows updates (as driver, firmware updates, etc.). These types of patches may require a reboot during the Hotpatch months.

Benefits of Hotpatching

The benefits of this technology are many:

Better security: with hotpatching, security patches are applied quickly and efficiently. This reduces the window of vulnerability between the release of a patch and its application, offering fast protection against threats.
Minimization of downtime: one of the main benefits of hotpatching is the ability to apply updates without the need to restart the server. This means fewer outages and higher availability for applications and services.
More flexible management: system administrators have the freedom to decide when to apply patches, without the worry of having to do careful planning to ensure that running processes are not interrupted while applying updates.

How hotpatching works

During a hotpatching process, the security patch is injected into the operating system's running code in memory, updating the system while it is still running.

Hotpatch works by first establishing a baseline with the current Cumulative Update for Windows Server. Periodically (on a quarterly basis), the baseline is updated with the latest Cumulative Update, after which they are released hotpatch for the next two months. For example,, if a Cumulative Update is released in January, February and March would see the release of hotpatch. For the hotpatch release schedule, you can consult the Release Notes for Hotpatch in Azure Automanage for Windows Server 2022.

The hotpatch contain updates that do not require a restart. Because Hotpatch fixes the in-memory code of running processes without the need to restart the process, applications hosted on the operating system are not affected by the patching process. This action is separate from any performance and functionality implications of the patch itself.

The following image shows an example of an annual update release schedule (including examples of unplanned baselines due to zero-day corrections).

Figure 1 – Outline of a sample yearly schedule for releasing Hotpatch updates

There are two types of baselines:

Planned Baselines: are released on a regular basis, with hotpatch releases in between. Planned Baselines include all updates in a newer Cumulative Update and require a restart.
Unplanned Baselines: they are released when a major update is released (like a zero-day correction) and that particular update cannot be released as a hotpatch. When unscheduled baselines are released, a hotpatch release is replaced with an unplanned baseline in that month. Unplanned Baselines also include all updates in a newer Cumulative Update and require a restart.

The programming shown in the example image illustrates:

four baseline releases planned in a calendar year (five total in the diagram) and eight hotpatch releases;
two unplanned baselines that would replace the hotpatch releases for those months.

Patch orchestration process

Hotpatch is to be considered as an extension of Windows Update and patch orchestration tools vary depending on the platform in use.

Hotpatch orchestration on Azure

Virtual machines created in Azure are enabled by default for automatic patching when using a supported image of "Windows Server Datacenter: Azure Edition”:

patches classified as Critical or Security are automatically downloaded and applied to the VM;
patches are applied during off-peak hours considering the time zone of the VM;
Azure handles patch orchestration and patches are applied following the availability principles;
the health status of the virtual machine, determined through Azure platform health signals, is monitored for patching failures.

Hotpatch orchestration on Azure Stack HCI

Hotpatch updates for active VMs in Azure Stack HCI environment can be orchestrated using:

Group Policy to configure Windows Update client settings;
Windows Update client settings or SCONFIG per Server Core;
a third-party patch management solution.

Considerations and Limitations

However, like any technology, even hotpatching has its nuances. Not all patches are suitable for hotpatching; some may still require a traditional restart. Furthermore, before applying any patches, it remains crucial to test it in a controlled environment to avoid potential problems.

Installing Hotpatch updates does not support automatic rollback. In fact,, if a VM experiences a problem during or after an upgrade, you need to uninstall the update and install the latest known good baseline update. After the rollback you will need to restart the VM.

Conclusion

The introduction of hotpatching by Microsoft represents a significant step forward in the management of VMs running Windows Server operating system. With the ability to apply security patches and updates non-disruptively, administrators can ensure that their servers are protected and updated in a faster and more effective way. In a world where safety is paramount and where every second counts, hotpatching is positioned as a valuable solution for any company that uses Windows Server in an Azure environment or in an Azure Stack HCI environment.

Microsoft is constantly announcing news regarding Azure management services and as usual this monthly summary is released. The aim is to provide an overview of the main news of the month, in order to stay up to date on these topics and have the necessary references to conduct further exploration.

The following diagram shows the different areas related to management, which are covered in this series of articles:

Figure 1 – Management services in Azure overview

Monitor

Azure Monitor

Azure Monitor Agent Health experience (peview)

The Azure Monitor Agent (AMA) is responsible for collecting monitoring data from the guest operating system of the virtual machines, both in Azure and hybrid environments, which are then transmitted to Azure Monitor. Thanks to the Azure Monitor Agent Health experience, it is now possible to easily monitor the health of agents on a large scale, both on Azure, both locally (on-premise) or on other cloud infrastructures.

Improved table-level RBAC checking in Azure Monitor Logs

Azure Monitor Logs offers advanced role-based access management capabilities (RBAC) to enable secure management of sensitive logs in complex environments. Table-level access allows you to allow only a specific group of people to read the data, limiting access to only a selected set of tables. This new method works by assigning permissions to the sub-resource of the table, enabling granular RBAC even for custom log tables and ensuring the use of well-known standard Azure RBAC tools.

Events from Azure Event Hubs to Azure Monitor Logs

Azure Event Hubs provide a simple and powerful way to bring data into your Azure Monitor environment. Thanks to new feature, you can now send events directly from an Event Hub into the Log Analytics workspace. Azure Event Hubs is a big data streaming platform that allows you to collect events from different sources, ready to be processed by various Azure services and other external platforms. This ability to ingest data is particularly beneficial for those who already use queue messaging mechanisms and have an interest in moving the data into a Log Analytics workspace, in Sentinel, or to route them to multiple destinations.

Support for Azure Monitor Sandboxing Pod in Container insights

Container Insights now supports container tracking “Pod Sandboxing”. The concept of Pod Sandboxing represents an effective strategy to protect yourself from situations of “Container Breakout”, where a user, both malicious and legitimate, manages to break through container isolation to access the filesystem, to processes, to network interfaces and other resources on the host machine. In the past, isolation could be achieved through the use of node pools, but this approach generated significant operational overhead and required additional resources, increasing overall costs. Thanks to the adoption of Pod Sandboxing, this issue is addressed through kernel-level workload isolation, providing a more efficient and secure solution.

Azure by your side: new solutions for Windows Server 2012/R2 end of support

In the era of Artificial Intelligence and native services for the cloud, organizations continue to rely on Windows Server as a secure and reliable platform for their mission-critical workloads. However, it is important to note that support for Windows Server 2012/R2 will end on 10 October 2023. After that date, Windows Server 2012/R2 systems will become vulnerable if action is not taken, as they will no longer receive regular security updates. Recently, Microsoft has announced that Azure offers new solutions to better manage the end of support of Windows Server 2012/R2. These solutions will be examined in detail in this article, after a brief summary to set the context.

The impact of end of support for Windows Server 2012 R2: what it means for companies?

Microsoft has announced the end of support for Windows Server 2012 and 2012 R2, fixed for 10 October 2023. This event represents a turning point for many organizations that rely on these servers to access applications and data. But what exactly does end of support mean (EOL) and what are the implications for companies?

Understanding end of support

Microsoft has a lifecycle policy that provides support for its products, including Windows Server 2012 and 2012 R2. End of support refers to when a product is no longer supported by Microsoft, which means no more security updates will be provided, patches or technical support.

Why companies should care

Without regular updates and patches, companies using Windows Server 2012 and 2012 R2 are exposed to security vulnerabilities, such as ransomware attacks and data breaches. Furthermore, using an unsupported product such as Windows Server 2012 or 2012 R2 can lead to non-compliance issues. Finally, outdated software can cause compatibility issues with newer applications and hardware, hampering efficiency and productivity.

An opportunity to review IT strategy

Companies should use the EOL event as an opportunity to review their IT strategy and determine the desired business goals for their technology. In this way, they can align the technology with their long-term goals, leveraging the latest cloud solutions and improving operational efficiency.

The strategies that can be adopted to deal with this situation, thus avoiding exposing your IT infrastructure to security issues, have already been addressed in the article: How the End of Support of Windows Server 2012 can be a great opportunity for CTOs.

About this, Microsoft has introduced two new options, provided through Azure, to help manage this situation:

updating servers with Azure Migrate;
distribution on Azure Arc-enabled servers of updates deriving from the ESU (Extended Security Updates).

The following paragraphs describe the characteristics of these new options.

Updating Windows servers in end of support phase (EOS) with Azure Migrate

Azure Migrate is a service offered by Microsoft Azure that allows you to assess and migrate on-premises resources, as virtual machines, applications and databases, towards the Azure cloud infrastructure. Recently, Azure Migrate has introduced support for in-place upgrades for Windows Server 2012 and later, when moving to Azure. This allows organizations to move their legacy applications and databases to a fully supported operating system, compatible and compliant as Windows Server 2016, 2019 or 2022.

Key benefits of Azure Migrate's OS update feature

Risk mitigation: Azure Migrate creates a replica of the original server in Azure, allowing the OS to be updated on the replica while the source server remains intact. In case of problems, customers can easily go back to the original operating system.

Compatibility Test: Azure Migrate provides the ability to perform a test migration in an isolated environment in Azure. This is especially useful for OS updates, allowing customers to evaluate the compatibility of their operating system and updated applications without impacting production. This way you can identify and fix any problems in advance.

Reduced effort and downtime: integrating OS updates with cloud migration, customers can significantly save time and effort. With only one additional data, the version of the target operating system, Azure Migrate takes care of the rest, simplifying the process. This integration further reduces downtime of the server and applications hosted on it, increasing efficiency.

No separate Windows licenses: with the Azure Migrate OS update, you do not need to purchase an operating system license separately to upgrade. That the customer uses Azure Hybrid Benefits (AHB) o PAYG, is covered when migrating to an Azure VM using Azure Migrate.

Large-scale server upgrade: Azure Migrate supports large-scale server OS upgrades, allowing customers to upgrade up to 500 server in parallel when migrating to Azure. Using the Azure portal, you will be able to select up to 10 VMs at a time to set up replicas. To replicate multiple VMs you can use the portal and add VMs to be replicated in multiple batches of 10 VMs, or use the Azure Migrate PowerShell interface to configure replication.

Supported OS versions

Azure Migrate can handle:

Windows Server 2012: supports upgrading to Windows Server 2016;
Windows Server 2012 R2: supports upgrading to Windows Server 2016, Windows Server 2019;
Windows Server 2016: supports upgrading to Windows Server 2019, Windows Server 2022;
Windows Server 2019: supports upgrading to Windows Server 2022.

Deployment of ESU-derived updates on Azure Arc-enabled servers

Azure Arc is a set of Microsoft solutions that help businesses manage, govern and protect assets in various environments, including on premise, edge e multi-cloud, extending the management capabilities of Azure to any infrastructure.

For organizations unable to modernize or migrate before Windows Server 2012/R2 end of support date, Microsoft has announced Extended Security Updates (ESU) enable Azure Arc. With Azure Arc, organizations will be able to purchase and distribute Extended Security Updates seamlessly (ESU) in on-premises or multicloud environments, direct from the Azure Portal.

To get Extended Security Updates (ESU) for Windows Server 2012/R2 and SQL Server 2012 enable Azure Arc, you need to follow the steps below:

Preparing the Azure Arc environment: first of all, you need an Azure environment and a working Azure Arc infrastructure. Azure Arc can be installed on any server running Windows Server 2012/R2 or SQL Server 2012, provided that the connectivity requirements are met.
Server registration in Azure Arc: once the Azure Arc environment is set up, you need to register your Windows servers or SQL Server systems in Azure Arc. This process allows systems to become managed resources in Azure, making them eligible for ESUs.
Purchase of ESUs: once the servers are registered in Azure Arc, ESUs can be purchased, for each server you want to protect, through Azure.
ESU activation: after the purchase of the ESUs, you need to activate them on the servers. This process involves installing a license key and downloading security updates from Windows Update or your local update distribution infrastructure.
Installing updates: finally, once the ESUs are activated, you can install security updates on servers. This process can be managed manually or by automating it through update management tools.

Note: ESUs only provide critical and important security updates, they do not include new features or performance improvements. Furthermore, ESUs are only available for a limited time after Microsoft's end of support. Therefore, we recommend that you consider migrating to newer versions of servers to have access to all features, in addition to security updates.

Conclusions

This year, Microsoft celebrates the 30th anniversary of Windows Server, a goal achieved thanks to relentless innovation and customer support. However, customers must commit to keeping their Windows Server systems up-to-date near the end of support. In particular, the end of support for Windows Server 2012 and 2012 R2 poses a significant risk to companies, but it also presents an opportunity to review and improve their IT strategy. Identifying desired business goals, engaging in strategic planning e, if necessary, using these new solutions offered by Azure, companies can ensure a smooth and successful transition, optimizing their IT infrastructure to achieve their long-term goals.

ExpressRoute private peering now supports the use of custom Border Gateway Protocol (BGP) communities with virtual networks connected to your ExpressRoute circuits. Once you configure a custom BGP community for your virtual network, you can view the regional and custom community values on outbound traffic sent over ExpressRoute when originating from that virtual network. These values can be used when applying filters or specifying routing preferences for traffic sent to your on-premises from your Azure environment.

Azure Virtual Network encryption

With Virtual Network encryption, customers can enable encryption of traffic between Virtual Machines and Virtual Machines Scale Sets within the same virtual network and between regionally and globally peered virtual networks. This new feature enhances the existing encryption in transit capabilities in Azure.

Sensitive Data Protection for Application Gateway Web Application Firewall logs (preview)

Azure’s regional Web Application Firewall (WAF) running on Application Gateway now supports sensitive data protection through log scrubbing. When a request matches the criteria of a rule, and triggers a WAF action, that event is captured within the WAF logs. WAF logs are stored as plain text for debuggability, and any matching patterns with sensitive customer data like IP address, passwords, and other personally identifiable information could potentially end up in logs as plain text. To help safeguard this sensitive data, you can now create log scrubbing rules that replace the sensitive data with “******”.

Microsoft Azure and Nutanix: a strategic partnership for hybrid cloud

In the last few years, the adoption of cloud computing has grown exponentially, revolutionizing the way organizations manage their IT assets. One of the key concepts that has gained popularity is the “hybrid cloud”, an operating model that combines the best of public and private cloud services in a single flexible solution. To deliver new hybrid cloud solutions that combine application agility with unified management between private cloud and Azure, Microsoft has entered into a strategic partnership with Nutanix, leader in hyperconverged infrastructure. This article will explore the key details of this strategic partnership, illustrating how hybrid cloud solutions offered by Azure and Nutanix can help companies achieve their digital transformation goals, while ensuring security, reliability and efficiency, essential for success in the cloud era.

Recognizing the need to offer solutions that fit specific customer needs, Microsoft Azure was designed from the ground up with the goal of reducing cost and complexity, while improving reliability and efficiency. This vision has materialized into a comprehensive platform that offers choice and flexibility for your IT environment.

Figure 1 – Overview of the possibilities offered by Microsoft Azure in terms of infrastructure

Moving to the cloud is not always a smooth process and there are situations where existing on-premises platforms continue to play a vital role. Azure enables customers to adopt the cloud at their own pace, ensuring continuity in the use of already known local platforms. This opportunity has long been available for VMware and is now also available for Nutanix.

What are Nutanix Cloud Clusters (NC2)?

Nutanix Cloud Cluster (NC2) are bare metal instances that are physically located within public clouds, including Microsoft Azure and AWS. NC2 runs the core of the Nutanix HCI stack, which includes the following main components:

Nutanix Acropolis Hypervisor (AHV): the Kernel-based Virtual Machine-based hypervisor (KVM) open source;
Nutanix Acropolis Operating System (AOS): the operating system that abstracts the Nutanix components to the end user, such as KVM, virsh, qemu, libvirt and iSCSI, and which manages the entire backend configuration;
Prism: the solution that provides administrators with centralized access to configure, easily monitor and manage Nutanix environments.

Figure 2 – Overview of Nutanix Cloud Cluster on Azure

The Nutanix cluster on Azure will consist of at least three nodes. SKUs available for NC2 on Azure, with core details, RAM, storage and network are available at this link.

The connection of the on-premise environment to Azure is supported both via Express Route, both via VPN Gateway.

An example of implementation of NC2 is shown, from a networking point of view, in Azure:

Figure 3 – Example implementation of NC2 in Azure

Main adoption scenarios

The adoption of the Nutanix solution in Azure can take place to address the following scenarios:

disaster recovery and business continuity;
need to expand your data center;
need to quickly and easily migrate your Nutanix workloads to Azure

Benefits of this solution

The main benefits that can be obtained by adopting this solution are reported.

Adopt a consistent hybrid deployment strategy: a consistent hybrid deployment strategy can be established, combining on-premises resources with Nutanix clusters in Azure. This allows you to operate in a homogeneous way and without diversity between the two environments.
Easy activation and scalability: with Azure, you have the ability to easily activate and scale applications and services without encountering particular limitations. Indeed, the global infrastructure of Azure provides the scalability and flexibility necessary to meet changing business needs.
Optimization of investments made: you can continue to leverage your investment in Nutanix tools and expertise.
Modernization through the potential of Azure: with Azure, it is possible to modernize the architecture through the integration with innovative and cutting-edge services. In fact,, once customers activate their Nutanix environment, can benefit from further integration with Azure, enabling application developers to access the full ecosystem of services offered by Azure.

Cost model

Customers must bear costs to purchase Nutanix software and must pay Microsoft for use of cloud resources. Nutanix software on clusters can be licensed in several ways:

BYO licenses (Bring Your Own): this type of license allows customers to use their own Nutanix licenses they already own or are purchasing. In this way, customers can port their on-premises licenses to NC2. It is important to note that the Nutanix AOS license must be of the Pro or Ultimate type, since the AOS Starter license cannot be used with NC2.
PAYG (Pay-As-You-Go): this licensing model provides hourly payments based on the number of cores used or SSD usage. Customers pay only for resources actually used during the time the cluster is active.
Cloud Commit: this model requires a minimum commitment from the customer for a specific period of time. Customers commit to using Nutanix resources on NC2 for a specific period and receive preferential rates based on that commitment.

Support options

Microsoft offers support for NC2 bare metal infrastructure on Azure. To request assistance, simply open a specific request directly from the Azure portal. Nutanix, instead, provides support for NC2 Nutanix software on Azure. This level of support is called Production Support for NC2.

Conclusions

Thanks to the collaboration between Microsoft and Nutanix, this solution offers customers who already have a Nutanix on-premises environment the possibility to take advantage of the same features also in the Microsoft public cloud, also allowing you to access the wide range of services offered by Azure. This solution makes it possible to adopt a consistent operating model, which can increase agility, the speed of deployment and resiliency of critical workloads.

support for all AKS node types: Linux and Windows;
ease of deployment using native Azure tools: AKS CLI, ARM models, PowerShell, etc.;
integration with Azure-managed Prometheus and Grafana offerings.

Azure Monitor Alert resources are now visible in the Azure portal

Historically, alert resources (alert rules, alert processing rules and action groups) have always been hidden resources in the Azure portal. This prevented them from appearing when searching or in the resource list and limited their viewing experience. Now Microsoft is making these resources “first-class citizens” in the Azure portal, so that they become visible in all places where the assets can be viewed in the portal, and more precisely the alerting resources:

appear in the search results in the top search bar of the Azure portal;
they appear when listing resources within a subscription or resource group;
they can now be viewed in a standard resource pane and will soon be editable as well (the same way you edit any other Azure resource).

Azure Monitor container insights for AKS cluster with ARM64 nodes

Container insights is a feature designed to monitor the performance of container workloads deployed in the cloud. Provides performance visibility by collecting processor and memory metrics from controllers, nodes and containers available in Kubernetes through the Metrics API. Azure Monitor container insights is now available for AKS clusters with ARM64 nodes.

Managed identity authentication in Azure Monitor Container Insights

Managed Identity is a secure and streamlined authentication model where the Azure Monitor monitoring agent uses the cluster's managed identity to send data to the Azure Monitor backend. This mechanism replaces the current certificate-based local authentication and eliminates the need to add a monitoring metrics publisher role to the cluster. Managed Identity will now be the default authentication mechanism for Container Insights.
