SRS-049: High Availability and Load Balancing Support

Identifier​

SRS-049

Software System​

  • Orchestrator
  • Application Instance

Category​

  • Installation
  • Maintenance

Description​

The software shall be designed to operate in a horizontally-scalable, high-availability configuration. Each application instance must be stateless, not storing any session-specific data locally between requests. This design allows for incoming API traffic to be distributed across multiple server instances by a load balancer, ensuring system stability, scalability, and uninterrupted service during single-node failures or rolling updates.

Derived from PRS​

  • PRS-1V6: Expose the device’s functionality through a versioned, network-accessible API
