The peculiarities and undeniable advantages of cloud computing can, in certain situations, hide pitfalls if not handled with due attention. 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.

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.

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.

Azure Stack HCI: IT infrastructure innovation that reduces environmental impact

The era of technological innovation has a duty to merge with environmental sustainability, and Microsoft Azure Stack HCI represents a significant step forward in this direction. In the fast-paced world of enterprise IT, organizations are constantly looking for solutions that not only offer excellent performance and innovation, but which also contribute to reducing the environmental impact of their IT infrastructures. Azure Stack HCI stands as a cutting-edge solution that combines technological excellence with a commitment to environmental sustainability. In this article, we will explore the positive environmental implications of adopting Azure Stack HCI.

Reduction of energy consumption

In a hyper-converged infrastructure (HCI), several hardware components are replaced by software, which combines the processing layers, storage and networking in a single solution. Azure Stack HCI is the Microsoft solution that allows you to create a hyper-converged infrastructure (HCI), where computing resources, storage and networking are consolidated into a single platform. This eliminates the need for separate devices, such as appliance, storage fabric and SAN, leading to an overall reduction in energy consumption. Furthermore, Azure Stack HCI systems are purpose-built to operate efficiently, making the most of available resources. This elimination of separate devices and optimization of resources help reduce the amount of energy required to maintain and cool the infrastructure, thus contributing to the reduction of carbon emissions.

Figure 1 – "Three Tier" Infrastructure vs Hyper-Converged Infrastructure (HCI)

Intelligent use of resources

Azure Stack HCI allows you to flexibly scale resources based on workload needs and allows you to extend its functionality with Microsoft Azure cloud services, including:

Azure Site Recovery to implement disaster recovery scenarios;
Azure Backup for offsite protection of your infrastructure;
Update Management which allows you to make an assessment of the missing updates and proceed with the corresponding deployment, for both Windows machines and Linux systems, regardless of their geographical location;
Azure Monitor which offers a centralized way to monitor and control what is happening at the application level, network and hyper-converged infrastructure, using advanced analytics based on artificial intelligence;
Defender for Cloud which guarantees monitoring and detection of security threats on workloads running in the Azure Stack HCI environment;
Cloud Witness to use Azure storage account as cluster quorum.

Furthermore, there is the possibility of modernizing and making the file server more efficient as well, which remains a strategic and widely used component in data centers, by adopting the solution Azure File Sync. This solution allows you to centralize the network folders of the infrastructure in Azure Files, while ensuring flexibility, the performance and compatibility of a traditional Windows file server. Although it is possible to maintain a complete copy of the data in an on-premises environment, Azure File Sync turns Windows Server into a “cache” which allows quick access to the contents present in a specific Azure file share: then, all files reside in the cloud, while only the latest files are also kept in the on-premises file server. This approach allows you to significantly reduce the storage space required in your datacenter.

Figure 2 – Platform integration with cloud solutions

Thanks to virtualization, the dynamic allocation of resources and the adoption of solutions in the cloud environment, you can use only the resources you need on-premises, avoiding waste of energy. This approach to infrastructure reduces the environmental impact of manufacturing, management and disposal of obsolete hardware components.

Optimization of physical space

Consolidating resources into a single Azure Stack HCI platform reduces the need for physical space for server installation, storage devices and network devices. This results in a significant reduction in the surface area occupied in server rooms, allowing for more efficient space management and higher computational density. In turn, the reduction of the occupied space means lower cooling and lighting needs, thus contributing to overall energy savings.

Conclusions

The adoption of Microsoft Azure Stack HCI offers significant benefits in terms of environmental sustainability. The reduction of energy consumption, resource optimisation, the intelligent use of physical space and the wide flexibility help to reduce the environmental impact of data centers and IT infrastructures. Azure Stack HCI represents a step forward towards the adoption of more sustainable IT solutions, enabling organizations to optimize resources, reduce carbon emissions and promote more efficient and environmentally conscious management of IT resources.
