Horizontally partitioning data across multiple database instances, distributing load and enabling storage beyond single-server limits.
Sharding splits data by a shard key (like user ID, region, or date range) so each shard holds a subset of the total data. This enables horizontal scaling but adds complexity for cross-shard queries, transactions, and rebalancing.
Sharding a multi-tenant SaaS application by tenant ID so each customer's data lives on a dedicated database shard.
Most businesses don't need sharding until they hit millions of records or thousands of concurrent queries. Vertical scaling (bigger server) is simpler and should be exhausted first.
