What is the difference and connection between the distributed service architecture and the MicroServices architecture concept

Distributed: Decentralized pressure.

MicroServices: Decentralized capabilities.

today's understanding of distributed: Different modules deployed on different servers: distributed solutions for high concurrency problems cluster: The same service multiple servers deploy the same application to form a cluster role: through the load Balancer equipment to provide services soa[Assembly services/ESB Enterprise Service Bus] The business system is decomposed into multiple components, allowing each component to independently provide discrete, autonomous, reusable service capabilities through the combination and orchestration of services to achieve the upper-level business process: simplifying maintenance, reducing overall risk, scaling flexible microservices [Find service/microservices Gateway Open API] Architecture design concepts, Each service interval (distributed is also isolated), autonomous (distributed dependent overall combination) Other features (single duty, boundary, asynchronous communication, standalone deployment) are distributed concepts that closely follow the evolutionary process of SOA to MicroServices architecture: each service can be applied independently, and a combination service can be applied in a system (Boulder applications [ Monolith] Simplified implementation strategy-platform thinking)
