Microsoft Launches Azure Cobalt 100 VMs: A New Era in Cloud Performance

On November 8, 2024, Microsoft announced that its innovative Azure Cobalt 100-based virtual machines (VMs) are now generally available. This launch, which officially took place on October 16, marks a significant milestone in Microsoft's cloud computing infrastructure and their commitment to pushing the boundaries of performance and efficiency.

A Breakdown of the Cobalt 100 Architecture​

The Azure Cobalt 100 VMs are powered by Microsoft's first in-house designed 64-bit Arm-based Azure Cobalt 100 CPU. This custom chip, which was first revealed in November 2023, is engineered specifically to meet modern cloud demands and tackle diverse workloads efficiently.

Key Specs of Cobalt 100 VMs:​

• Architecture: 64-bit Arm-based
• General-purpose Options: Dpsv6 and Dplsv6 series
• Memory-optimized: Epsv6 series
• Performance:
  • Up to 50% better price-performance compared to previous Arm-based offerings.
  • Enhanced CPU performance by up to 1.4 times.
  • Performance improvements on Java workloads by up to 1.5 times.
  • Web server performance doubled compared to older models.

Memory and CPU Configurations:​

• The Dpsv6 and Dplsv6 series feature 96 virtual CPUs (vCPUs) and 384 GiB of RAM.
• The memory-optimized Epsv6 series provides up to 96 vCPUs and 672 GiB of RAM.

This level of specification positions the Cobalt 100 VMs as capable contenders in handling everything from routine computing tasks to more intensive applications like data analytics and real-time web services.

Deployment Across Regions​

Microsoft has rolled out these VMs in many regions, including:

• Canada Central
• Central US
• East US 2
• Germany West Central
• Japan East
• And several others.

Future deployments planned include regions like Australia East and Brazil South, ensuring that a wider audience can benefit from this cutting-edge technology.

Early Adoption and Industry Reaction​

Notable companies such as Cadence, Databricks, Elastic, Siemens EDA, and Snowflake have already begun harnessing the power of Cobalt 100 VMs, paving the way for increased productivity and performance in various tasks. Gabe Bryant, a senior manager at Snowflake, expressed excitement over their performance improvements when comparing the new VMs to their predecessors in real-world scenarios.
Mohamed Awad from Arm also lauded the collaboration with Microsoft, emphasizing the Cobalt 100’s design as a testament to the growing potential of Arm-based silicon in modern infrastructure.
