Microsoft Cloud for Sovereignty: the solution to meet sovereignty requirements in the cloud and hybrid environments

Microsoft has recently announced the availability of Microsoft Cloud for Sovereignty across all Azure regions. This solution offers reliable options for the public sector, designed to support the migration, development, and transformation of workloads in Microsoft’s cloud while complying with regulatory, security, and control requirements. In this article, we delve into the distinctive features of Microsoft Cloud for Sovereignty, exploring how it can ensure rapid digital transformation for government entities in compliance with regulations.

Sovereignty in the Hyperscale Cloud

Governments worldwide must meet a wide range of national and regional compliance requirements for applications and workloads, including governance, security controls, privacy, and in some cases, data residency and sovereign protections. Until now, most solutions to meet these regulatory requirements relied on private clouds and on-premises environments, slowing the adoption of scalable, secure, and resilient cloud solutions.

What is Data Sovereignty and Microsoft’s Stance on ‘Sovereignty’?

Data sovereignty is the concept that data is under the customer’s control and regulated by local laws. While data residency ensures data remains in a specific geographic location, data sovereignty ensures adherence to the regulations of the country where the public sector customer is located. Each jurisdiction has its own requirements, vision, and unique needs when it comes to addressing sovereignty. In this regard, while Microsoft believes many of these needs are met through standard cloud solutions, it has introduced Microsoft Cloud for Sovereignty, providing an additional layer of capabilities to meet the individual needs of public sector and government clients. It is then up to partners and clients to determine what is appropriate for their specific needs. For the most sensitive workloads that cannot be hosted in the public cloud, Microsoft offers hybrid options, such as Azure Stack HCI, allowing customers to keep data in their own on-premises environments.

The following paragraphs outline the most common requests for achieving data sovereignty in the cloud.

Residency, Security, and Compliance in the Hyperscale Cloud

Microsoft Cloud for Sovereignty is rooted in over 60 global Azure cloud regions, ensuring unmatched security and a wide range of regulatory compliance. This positions Microsoft as the cloud provider with the most regions worldwide, and this infrastructure allows customers to implement specific policies to ensure their data and applications remain within their preferred geographic boundary, fully respecting national or regional data residency requirements.

Controls for Data Access

Microsoft Cloud for Sovereignty provides controls to ensure sovereignty, protection, and encryption of sensitive data and to control access, enabled by:

  • Sovereign Landing Zone: A specific Azure landing zone designed for entities requiring privacy, security, and sovereign controls in compliance with governmental regulations. These zones provide a repeatable and secure approach for cloud service development and deployment. Governments facing complex and multilevel regulatory contexts find in the Sovereign Landing Zones an effective solution for designing, implementing, and managing solutions, adhering to established policies. They allow for the implementation and configuration of Azure resources, ensuring alignment with the best practices of the Cloud Adoption Framework (CAF). These guides enable organizations to meet data sovereignty requirements. For more information on SLZ and their features, it is recommended to consult the documentation on GitHub.
  • Azure Confidential Computing: A technology developed by Microsoft aimed at enhancing data security while being processed in the cloud. Traditionally, data can be protected while at rest (stored) or in transit (during transmission), but become vulnerable when in use or running on a server. Confidential Computing seeks to bridge this gap by protecting data even when in execution. This is achieved through the use of a technology called “Trusted Execution Environment” (TEE), which is essentially a secure area of the processor. TEEs isolate data and code in execution from other processes, including those of the operating system, so that only authorized code can access the data. This means that even if an attacker manages to penetrate the operating system or network, they would not be able to access the protected data within the TEE. Azure Confidential Computing is particularly useful for use cases requiring a high level of data security, such as financial transactions, healthcare information management, or handling sensitive data for businesses or governments.

The Complexity of Addressing Regulations that Vary from Country to Country

Digital sovereignty is a complex issue, varying significantly from one nation to another.

Wise cost management is one of the crucial aspects of cloud governance. In this article, will be explored and outlined the principles and techniques that can be used to optimize and minimize expenses relating to the resources implemented in the Azure environment.

The issue of optimizing costs related to the cloud is a topic that is attracting increasingly greater interest among numerous customers. So that, for the seventh year in a row, emerges as the leading initiative in the cloud industry, as reported in Flexera's annual report 2023.

Figure 1 – Initiatives reported in the Flexera report of 2023

Principles to better manage costs

For effective management of costs associated with Azure, It is essential to adopt the principles outlined in the following paragraphs.

Design

A well-structured design process, which includes a meticulous analysis of business needs, it is essential to customize the adoption of cloud solutions. It therefore becomes crucial to outline the infrastructure to be implemented and how it will be used, through a design plan that aims to optimize the efficiency of the resources allocated in the Azure environment.

Visibility

It is vital to equip yourself with tools that offer a global view and allow you to receive notifications regarding Azure costs, thus facilitating constant and proactive monitoring of expenses.

Responsibility

Assigning cloud resource costs to the respective organizational units within the company is a smart practice. This ensures that managers are fully aware of the expenses attributable to their team, promoting an in-depth understanding of Azure spending at an organizational level. For this purpose, It is advisable to structure Azure resources in such a way as to facilitate the identification and attribution of costs.

Optimization

It is advisable to undertake periodic reviews of Azure resources with the intention of minimizing expenses where possible. Making use of available information, you can easily identify underutilized resources, eliminate waste and capitalize on cost saving opportunities.

Iteration

It is essential that IT staff are continuously engaged in the iterative processes of optimizing the costs of Azure resources. This represents a key element for responsible and effective management of the cloud environment.

Techniques to optimize costs

Regardless of the specific tools and solutions used, to refine cost management in Azure, you can adhere to the following strategies:

  • Turn off unused resources, given that the pricing of the various Azure services is based on the actual use of the resources. For those resources that do not require uninterrupted operation and that allow, without any loss of configurations or data, a deactivation or suspension, it is possible to implement an automation system. This system, regulated by a predefined schedule, facilitates the optimization of use and, consequentially, more economical management of the resources themselves.
  • Adequately size resources, consolidating workloads and proactively intervening on underutilized resources, allows us to avoid waste and guarantee a more efficient and targeted use of available capacities.
  • For resources used continuously in the Azure environment, evaluate the option of Reservations can prove to be an advantageous strategy. Azure Reservations offer the opportunity to benefit from a significant cost reduction, which can reach up to 72% compared to pay-as-you-go rates. This benefit can be obtained by committing to pay for the use of Azure resources for a period of one or three years. This payment can be made in advance or on a monthly basis, at no additional cost. The purchase of Reservations can be made directly from the Azure portal and is available to customers with the following subscription types: Enterprise Agreement, Pay-As-You-Go and Cloud Solution Provider (CSP).
  • To further mitigate costs associated with Azure, it is appropriate to consider the implementation of’Azure Hybrid Benefit. This advantage allows you to achieve significant savings, as Microsoft only allows you to bear the costs relating to the Azure infrastructure, while the licenses for Windows Server or SQL Server are covered by a Software Assurance contract or an existing subscription.

The Azure Hybrid Benefit can also be extended to Azure SQL Database, to SQL Servers installed on Azure virtual machines and SQL Managed Instances. These benefits facilitate the transition to cloud solutions, bidding up to 180 days of dual use right, and help leverage pre-existing investments in terms of SQL Server licenses. To learn more about how to use the Azure Hybrid Benefit for SQL Server, please consult the FAQs present in this document. It is important to note that this benefit is also applicable to RedHat and SUSE Linux subscriptions, further expanding the opportunities for savings and cost optimization.

The Azure Hybrid Benefit can be combined with Azure Reserved VM Instances, creating an opportunity for significant savings that can reach 80% of the total, especially when you opt for an Azure Reserved Instance purchase for the duration of 3 years. This synergy not only makes the investment cheaper, but also maximizes operational efficiency.

  • Considering the integration of new technologies and the application of architectural optimizations is crucial. This process involves the selection of the most appropriate Azure service for the specific needs of the application in question, ensuring not only optimal technological alignment, but also more efficient cost management.
  • Allocate and de-allocate resources dynamically is critical to meeting fluctuating performance needs. This approach is known as “autoscaling”, a process that facilitates the flexible allocation of resources to meet specific performance needs at any time. As the workload intensifies, an application may require additional resources to maintain desired performance levels and meet SLAs (Service Level Agreement). On the contrary, when demand reduces and additional resources are no longer essential, these can be de-allocated to minimize costs. Autoscaling capitalizes on the elasticity of cloud environments, allowing not only more effective cost management, but also reducing the administrative burden, as resources can be managed more smoothly and with less manual intervention.
  • For test and development environments, it is advisable to consider the use of Dev/Test subscriptions, which offer the opportunity to access significant discounts on Azure fees. These subscriptions can be activated under an Enterprise Agreement, thus facilitating more advantageous cost management and more agile and economical experimentation during the development and testing phases.

Conclusions

The adoption of a methodological approach in managing cloud costs, together with the use of appropriate strategies, represents a fundamental pillar for successfully navigating the complex challenge of cloud economic management. Drawing from the principles and techniques outlined in this article, users can not only optimize expenses, but also make the most of their investment in the cloud, ensuring a balance between costs and benefits.

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.
