Answer
Through horizontal scaling, partitioning/sharding, and stateless services.
Quick Answer
Microservices scale horizontally by running more instances. Each service scales independently based on its specific bottleneck. Auto-scaling reacts to metrics (CPU, memory, queue depth, custom metrics). Services are stateless (session in Redis not in-process), so any instance can handle any request. Load balancers distribute traffic across all instances.
