Service architecture diagram of Nacos series

Last one Nacos Official architecture , We need to analyze their underlying design principles first

 Provider APP： Service providers

Consumer APP： Serving consumers

Name Server： adopt VIP or DNS The way to achieve Nacos High availability cluster service routing

Nacos Server：Nacos Service provider , Including the OpenAPI,Config Service、Naming Service All are Nacos Configuration and name service module provided ,Conststency Protocol It's a consistency agreement , The function is to realize Nacos The data synchronization of cluster nodes is used here Raft Algorithm ( A very popular algorithm ,Redis This algorithm is used in the master-slave election )

Nacos Console：Nacos Console

in general , In this ecology , Service provider through VIP visit Nacos Server High availability cluster , be based on Open API Complete service registration and service query ,Nacos Server It can support active and standby mode , Therefore, the bottom layer will use the data consistency algorithm to complete the data synchronization of the slave node , The same is true for service consumers , be based on Open API from Nacos Server Query the service list in
