Developing open-source software for Arm64 architecture faces CI/CD environment challenges due to historical disadvantages compared to x86. Developers need consistent tools and methods across platforms, avoiding distinct procedures for less common architectures. Performance is crucial, ensuring deployment schemes don't slow down when supporting multiple platforms. Comprehensive testing coverage is essential, with identical tests for efficiency, compliance, and security on all platforms. Maintainability allows developers to automate integration and redevelopment processes across all platforms seamlessly. Product managers share these needs and require additional considerations. They also need efficient resource allocation and cost-effectiveness for multi-architecture builds. Ultimately, the goal is to build, test, deploy, and maintain across architectures, including Arm64. Successful multi-architecture support requires addressing these developer and product manager expectations. Achieving parity in development support is key to encouraging wider adoption of Arm64. This includes making Arm64 environments easy to use and cost-effective.
