Design and Optimization of an App Operation Platform: Ensuring High Availability, Performance, and Scalability

The APP operation system is a complex yet essential framework that aims to attract, retain, and monetize users, typically divided into a delivery engine and a distribution engine; the former handles intricate business logic, while the latter must endure massive traffic pressure.

The Yaoguang operation platform provides a flexible management solution that configures app operation slots across dimensions such as user profiles, app versions, dates, regions, and channels, enabling efficient and precise content delivery.

The platform consists of a delivery engine with six core modules—schedule management, creation, audit, delivery management, data dashboard, and strategy configuration—and a distribution engine composed of a front‑service and a distribution service, the latter requiring high‑performance caching to handle high concurrency.

Initial architecture relied on a centralized Redis cache supplemented by local caches, which struggled under massive distinct user requests, causing service pressure and potential outages. The optimized design shifts the primary data source to local caches, synchronizing with Redis via passive (publish‑subscribe) and active (startup and periodic tasks) mechanisms, eliminating central‑service bottlenecks.

After optimization, average response time dropped below 4 ms, and the system achieved high availability, high performance, and high scalability, allowing horizontal expansion without affecting core service stability.

In summary, the platform follows design principles of high availability (local cache with asynchronous sync), high performance (memory‑level data access), and high scalability (removing centralized dependencies), providing a robust solution for large‑scale app operation workloads.
