High-Availability Platform must simultaneously meet the following requirements:

High Availability: The system maintains continuous operation, with partial component failures not impacting overall service delivery.

Strong Scalability: Capable of rapid expansion to accommodate user growth or increased load.

However, scalability typically increases system complexity, such as:

Distributed architectures require handling node coordination, data consistency, and fault tolerance.

Microservices demand cross-service communication, version management, and monitoring.

Multi-region deployments necessitate load balancing and data synchronization strategies.
