By what methods is the scaling of a microservice system ensured?

Answer from AI
Scaling a microservices system is achieved through several methods:
-
Horizontal scaling — running multiple instances of a microservice to distribute the load. Usually implemented via container orchestrators (Kubernetes, Docker Swarm).
-
Vertical scaling — increasing resources (CPU, memory) for individual services, although this is less flexible.
-
Auto-scaling — configuring the system so that the number of instances changes depending on the load.
-
Sharding (functional partitioning) — distributing data and requests across different services or databases.
-
Using caching — to reduce load on services and databases.
-
Optimizing inter-service communication — reducing the number of synchronous calls, using asynchronous queues.
Example: in Kubernetes, you can configure a Horizontal Pod Autoscaler, which automatically increases the number of pods of a microservice as the load grows.
