Strategies include: vertical scaling, adding resources to one server; indexing, creating indexes on frequently queried columns; sharding, splitting data across different servers; vertical partitioning, separating columns into smaller tables; caching, storing frequently accessed data in a faster storage layer; replication, creating copies of the database in different regions; materialized views, pre-computing and storing complex query results; and data denormalization, introducing redundancy to optimize reads by combining tables. Each method has trade-offs and can be combined based on application needs. ## Full article daily.dev links to this article rather than hosting it.
