Architecture Notes: Keeping Services Stable Under Growth
A clear approach to evolving architecture without compromising reliability or delivery cadence.
Includes versioning, backward compatibility, and operational guardrails.
Principles
- Prefer additive changes and deprecate slowly.
- Design for observability from day one.
- Make performance budgets explicit.
架构笔记：在增长中保持系统稳定
在迭代与规模扩张中，保持稳定性与交付节奏的实践总结。
涉及版本兼容、灰度演进与运维护栏。
关键原则
- 优先增量演进，逐步弃用。
- 可观测性前置。
- 性能预算显性化。
