The beginning of 2024 was filled with exciting new announcements and events all over the world. Coming up, we’ll be at Open Source Summit North America (16-18), LinuxFest Northwest (April 26-28), and Red Hat Summit (May 6-9). If you’ll be at any of these events, we’d love to meet you!
What’s new with Linux on Azure
Red Hat Enterprise Linux pricing update
Red Hat announced that it is updating its Red Hat Enterprise Linux (RHEL) royalty model to a scalable model, which is expected to affect all Red Hat resellers across the market. In response to Red Hat’s price changes, Azure will also be rolling out price changes for all Red Hat Enterprise Linux instances. These changes started occurring on April 1, 2024, with price decreases for Red Hat Enterprise Linux and RHEL for SAP Business Applications licenses for vCPU sizes less than 12. All other price updates will be effective July 1, 2024. Read the blog for more details.

Azure IoT Edge supports Ubuntu Core Snaps
We announced that, in collaboration with Canonical, we addressed a longstanding request from our shared customers to support Ubuntu Core Snaps in Azure IoT Edge. The Tier 1 supported operating systems for Azure IoT Edge were expanded to include Ubuntu Core Snaps on AMD 64 and ARM 64. This expansion not only broadened the horizons for Azure IoT Edge applications, but also ensured seamless integration and development across a wider range of devices and systems.
