The problem we were facing in those days was than many new high-speed network technologies, such as ATM, became available for standard workstations but that the operating systems were not able to deliver those capabilities to its applications. The research to unlock these capabilities led to an architecture called U-Net.

Therefore, it’s critical to weigh the advantages of microservices against its potential issues, other architecture approaches, and your unique business needs.
