Elastic Cloud on Azure gets a speed boost: Compute-optimized instances on Azure Cobalt ARM
Elastic Cloud on Azure now supports compute-optimized hardware profiles utilizing Microsoft Cobalt ARM processors. Testing indicates significant price-performance gains for CPU-intensive workloads such as vector search, indexing, and aggregations. The new profiles leverage local NVMe storage and are accessible directly through the Azure Marketplace and the Elastic Cloud Console.
Elastic announced on September 24, 2026, that its cloud service on Azure now supports compute-optimized hardware profiles. These new instances utilize Microsoft's Cobalt ARM processors, specifically the Dpldsv6 virtual machine series. The profiles feature local NVMe direct-attach storage, distinguishing them from traditional remote-attached premium storage options. Elastic claims internal testing revealed up to 44 percent better price-performance compared to previous Fsv2 instances. This improvement applies consistently across CPU-intensive operations like indexing, aggregations, and various search types. The local storage design aims to deliver improved random read performance for compute-bound workloads. Users can access these profiles through the Azure Marketplace or the Elastic Cloud Console. The source indicates that specific regions for availability will expand over the coming months as capacity comes online. Elastic reserves the right to determine the release timing of any described features or functionality. Current access is limited to seven specific Azure regions, including those in Australia, the Netherlands, and the United States.
