Scaling microservices requires more than just breaking up a monolith. It requires specialized patterns to manage data consistency. Command Query Responsibility Segregation (CQRS) and Event Sourcing are two of the most powerful tools in an architect's arsenal.

By separating read and write operations, developers can optimize each side independently. This leads to massive performance gains in high-read or high-write scenarios common in enterprise software.
