CircleCI announced a preview of significant additions to their build fleet with the introduction of Arm-based compute. CircleCI is now one of the few platforms to offer cloud-based CI/CD services for the Arm architecture due to its partnership with Amazon Web Services (AWS), allowing joint customers to build and test applications compiled for Arm without managing their own systems. With Arm rapidly gaining traction across data center and edge applications, developing for Arm is a smart choice to help future-proof your business.
