Microsoft is announcing the general availability of the latest Azure Virtual Machines featuring the Ampere Altra Arm–based processor. The new virtual machines will be generally available on September 1, and customers can now launch them in 10 Azure regions and multiple availability zones around the world. In addition, the Arm-based virtual machines can be included in Kubernetes clusters managed using Azure Kubernetes Service (AKS). This ability has been in preview and will be generally available over the coming weeks in all the regions that offer the new virtual machines.

Earlier this year, we launched the preview of the new general-purpose Dpsv5 and Dplsv5 and memory optimized Epsv5 Azure Virtual Machine series, built on the Ampere Altra processor. These new virtual machines have been engineered to efficiently run scale-out, cloud-native workloads. Since then, hundreds of customers have tested and experienced firsthand the excellent price-performance that the Arm architecture can provide for web and application servers, open-source databases, microservices, Java and .NET applications, gaming, media servers, and more. Starting today, all Azure customers can deploy these new virtual machines using the Azure portal, SDKs, API, PowerShell, and the command-line interface (CLI).

Customers build and run a vast variety of workloads on Azure, whether they are digitally transforming and modernizing their businesses or building all-new innovative distributed apps and services that the world has never seen before. At the same time, customers want to maximize operational efficiency and are taking a holistic approach across their application portfolios. They are also beginning to evaluate sustainability factors and the overall impact of their technological choices. Azure’s Ampere Altra Arm–based virtual machines represent a cost-effective and power-efficient option that does not compromise the level of performance that customers require.

Accelerating developer productivity with Arm in the cloud

The Arm ecosystem continues to benefit from the contribution of the global community for most major developer platforms and languages such as Java, Python, Rust, PHP, .NET, and more.

Java has played a critical role in democratizing cross-platform development. Java developers can enjoy the development experience they are familiar with while building and running their applications with the Microsoft build of OpenJDK. Microsoft provides Java 11 and Java 17 binaries for Windows, Linux, and macOS. With Microsoft's recent JEP 388 contribution to OpenJDK, Java applications can now run on a wider range of Arm systems with no additional code changes.

Native support for the Arm architecture is available in .Net 6 on both Windows and Linux. With C# 10 and F# 6, .NET 6 delivers language improvements that simplify your code. Native support for Windows on Arm64 is now also available for the .NET Framework starting with the recent 4.8.1 release for Windows 11 and with Visual Studio 2022 17.3 generally available. The vast ecosystem of .NET Framework apps can receive the benefits of running on Arm now. The latest Microsoft Visual C++ tools (currently in preview and available as part of Visual Studio 17.4 preview) allow you to not just run your apps, but also build natively for Arm, on Arm. Visual Studio 17.4 previews support the desktop (C++ and C#), Web, and Universal Windows Platform (UWP) workloads and will be generally available later this year. The totally free Visual Studio Code editor running natively on Arm enables you to harness the power of the cloud—not just for your production environment, but now also for your development environment.

Outside the datacenter, the Arm hardware landscape continues to expand beyond mobile to a variety of client devices for customers looking for the battery life and performance benefits of Windows on Arm PCs and tablets. Until now, developers and software-provider partners building for Windows on Arm devices have had to build and test their software on physical devices or resort to cross-compilation and inefficient emulation solutions. To support their work, we’ve made Insider Preview releases of Windows 11 Pro and Enterprise available to run on Arm-based Azure VMs. Client application developers can now take advantage of Azure’s highly available, scalable, and secure platform to run cloud-based software and build and test workflows that help them increase their agility. NortonLifeLock was part of the preview:

"We are using Azure VMs featuring the Ampere Altra Arm-based processors to run and test Norton products supporting Windows 11 on Arm. We have found them appealing not only for performance and scalability, but from a cost perspective as well. Microsoft has made it easy for their customers to use their VMs seamlessly across different scenarios."—Leena Elias, Vice President of Product, NortonLifeLock
