just a simple remote procedure call. Distributed systems also mean that developers need to consider network latency, fault tolerance, message serialization, unreliable networks, asynchrony, versioning, load, and so on, while faced with so many microservices need to be distributed, the entire product needs to have a complete set of mechanisms to ensure that each service can function properly. transactional, asynchronous, test-facing challengesCross-process transactions, large amounts of asynch

the user can already see the interface. Can be very good to prevent the interface is too complex to cause the black screen time is too long, but this is only a way to improve the user experience, to root or optimize the interface.
