Feature Overview (aka. Goal Summary)

This feature aims to comprehensively refactor and standardize various components across HCP, ensuring consistency, maintainability, and reliability. The overarching goal to increase customer satisfaction by increasing speed to market and saving engineering budget by reducing incidents/bugs. This will be achieved by reducing technical debt, improving code quality, and simplifying the developer experience across multiple areas, including CLI consistency, NodePool upgrade mechanisms, networking flows, and more. By addressing these areas holistically, the project aims to create a more sustainable and scalable codebase that is easier to maintain and extend.

Goals (aka. Expected User Outcomes)

• Unified Codebase: Achieve a consistent and unified codebase across different HCP components, reducing redundancy and making the code easier to understand and maintain.
• Enhanced Developer Experience: Streamline the developer workflow by reducing boilerplate code, standardizing interfaces, and improving documentation, leading to faster and safer development cycles.
• Improved Maintainability: Refactor large, complex components into smaller, modular, and more manageable pieces, making the codebase more maintainable and easier to evolve over time.
• Increased Reliability: Enhance the reliability of the platform by increasing test coverage, enforcing immutability where necessary, and ensuring that all components adhere to best practices for code quality.
• Simplified Networking and Upgrade Mechanisms: Standardize and simplify the handling of networking flows and NodePool upgrade triggers, providing a clear, consistent, and maintainable approach to these critical operations.

Requirements (aka. Acceptance Criteria)

• Standardized CLI Implementation: Ensure that the CLI is consistent across all supported platforms, with increased unit test coverage and refactored dependencies.
• Unified NodePool Upgrade Logic: Implement a common abstraction for NodePool upgrade triggers, consolidating scattered inputs and ensuring a clear, consistent upgrade process.
• Refactored Controllers: Break down large, monolithic controllers into modular, reusable components, improving maintainability and readability.
• Improved Networking Documentation and Flows: Update networking documentation to reflect the current state, and refactor network proxies for simplicity and reusability.
• Centralized Logic for Token and Userdata Generation: Abstract the logic for token and userdata generation into a single, reusable library, improving code clarity and reducing duplication.
• Enforced Immutability for Critical API Fields: Ensure that immutable fields within key APIs are enforced through proper validation mechanisms, maintaining API coherence and predictability.
• Documented and Clarified Service Publish Strategies: Provide clear documentation on supported service publish strategies, and lock down the API to prevent unsupported configurations.

Use Cases (Optional)

• Developer Onboarding: New developers can quickly understand and contribute to the HCP project due to the reduced complexity and improved documentation.
• Consistent Operations: Operators and administrators experience a more predictable and consistent platform, with reduced bugs and operational overhead due to the standardized and refactored components.

Out of Scope

• Introduction of new features or functionalities unrelated to the refactor and standardization efforts.
• Major changes to user-facing commands or APIs beyond what is necessary for standardization.

Background

Over time, the HyperShift project has grown organically, leading to areas of redundancy, inconsistency, and technical debt. This comprehensive refactor and standardization effort is a response to these challenges, aiming to improve the project's overall health and sustainability. By addressing multiple components in a coordinated way, the goal is to set a solid foundation for future growth and development.

Customer Considerations

• Minimal Disruption: Ensure that existing users experience minimal disruption during the refactor, with clear communication about any changes that might impact their workflows.
• Enhanced Stability: Customers should benefit from a more stable and reliable platform as a result of the increased test coverage and standardization efforts.

Documentation Considerations

Ensure all relevant project documentation is updated to reflect the refactored components, new abstractions, and standardized workflows.

This overarching feature is designed to unify and streamline the HCP project, delivering a more consistent, maintainable, and reliable platform for developers, operators, and users.
