Cloud-Native Applications in Java

Benefits

The benefits of duplicating data are as follows:

• Helps decouple the service boundaries
• A business event containing the data is the only relationship between the services
• Helps avoid expensive distributed transaction models across boundaries
• Allows us to make changes to our service boundaries without impeding progress of other parts of the system
• We can decide how quickly or slowly we want to see the rest of the outside world and eventually become consistent
• Ability to store the data in our own databases using the technology appropriate for our service model
• Flexibility to make changes to our schema/databases
• Allows us to become much more scalable, fault tolerant, and flexible
