Canonical On Making Ubuntu For ARM64 "Truly A First-Class Architecture"

The Ubuntu Foundations Engineering Manager, Ravi Kant Sharma, with Canonical has provided an update regarding the current ARM64 state on Ubuntu Linux...

Why this matters
Why now

The increasing prevalence and performance of ARM-based hardware in servers, edge devices, and potentially AI compute necessitates robust software support from major operating system providers like Canonical.

Why it’s important

This move signals a strategic pivot by a major Linux distribution towards fully embracing ARM64, which is critical for diversifying the compute ecosystem and enhancing performance and efficiency across various applications.

What changes

Ubuntu's official, first-class support for ARM64 transforms it from a secondary architecture to a primary target, enabling more widespread ARM adoption in enterprise and cloud environments.

Winners
  • · ARM Holdings
  • · Cloud providers utilizing ARM64
  • · Edge computing developers
  • · Open-source ARM hardware manufacturers
Losers
  • · x86-dominant hardware providers
  • · Legacy software tied exclusively to x86
Second-order effects
Direct

Increased adoption of ARM64 CPUs for server and cloud workloads due to robust software support.

Second

Enhanced competition in the data center and server chip market, potentially leading to lower costs and greater innovation.

Third

Acceleration of sovereign compute initiatives as nations can more easily build infrastructure independent of Western x86 dominance.
