Main approaches to system scaling and expansion:
-
Vertical Scaling (Scaling Up) — increasing resources of a single server (CPU, RAM, disk). A simple method but limited by hardware capabilities.
-
Horizontal Scaling (Scaling Out) — adding new servers to the system, distributing load among them. Requires load balancing and data synchronization.
-
Caching — using caches (e.g., Redis, Memcached) to reduce database load and speed up response times.
-
Sharding — dividing data into parts (shards) for parallel processing and storage.
-
Queues and Asynchronous Processing — offloading peak loads using message brokers (Kafka, RabbitMQ).
-
Microservices Architecture — breaking down monoliths into independent services that can be scaled separately.
-
Auto-scaling — dynamically adding or removing resources based on load.
These approaches are often combined to achieve optimal system performance and stability.
