Following are a few of the advantages of this pattern:

• Splitting read operations and write operations to their own, Microservices help reduce its size. This in turn reduces the complexity of systems and helps improve scalability as you can scale the reads and writes independently.
• The read and write models can vary without affecting each other. This can help improve performance of read operations as you can denormalize the data or perform other operations to make read operations faster.
• You can run multiple versions of command handlers in parallel. This helps support deployment of new versions of Microservices.
