CNCF Projects, Including Crossplane, Enhance Arm64 Support with Oracle Cloud Credits

The Cloud Native Computing Foundation (CNCF) has been actively working to bolster Arm64 support across its diverse portfolio of projects, a crucial step given the rapid growth of Arm64 adoption in the cloud computing sector. A recent article highlights that over 50% of new instances on AWS and 33% on Azure were running on Arm64 CPUs by the end of 2025, underscoring the necessity for cloud-native projects to fully embrace this architecture. To facilitate this transition and ensure comprehensive Arm64 compatibility, Oracle Cloud Infrastructure (OCI) made a significant donation of $3 million in Arm64 compute resources in late 2023. These resources, powered by Ampere Computing CPUs, are specifically allocated to CNCF projects. The goal is to enable these projects to develop, build, and rigorously test their releases on Arm64, bringing them to parity with their x86 counterparts. Crossplane, a prominent CNCF project focused on managing cloud infrastructure using Kubernetes, is among the key beneficiaries of this initiative. The article explicitly mentions Crossplane alongside other projects like OpenTelemetry, Longhorn, and Jaeger, all of which have been leveraging these donated resources to enhance their Arm64 capabilities. This support is vital for Crossplane, as it allows platform teams and developers to provision and manage cloud resources consistently across different architectures, including the increasingly prevalent Arm64. The impact of native Arm64 continuous integration (CI) has been demonstrably positive, leading to improved project confidence and release quality. Project maintainers, such as those from OpenTelemetry, have reported high satisfaction with the performance and increasing adoption of Arm64 downloads. The CNCF Infra team has streamlined the process for projects to access OCI-hosted GitHub runners, making it easier for them to integrate Arm64 into their CI workflows. This strategic focus on Arm64 support ensures that CNCF projects remain at the forefront of cloud-native innovation, catering to the evolving demands of a multi-architectural cloud ecosystem.
