independently deployable

services.

Scale individual services independently based on demand without affecting other parts of the system.

Event-driven microservices can achieve better fault tolerance with despite not using Simple ACID transaction ( Either it completely happens or rollback when errors occur maintaining integrity within the managed microservices database itself)

Each service can be built using the most relevant technology stack.

Ex: Bidding could have redis and such in memory db for performance and Authentication could have more security oriented Databases
