[Daily Know] What is Dubbo? (2021.02.08)

First, let's talk about RPC

 
RPC

R & lt EMOTE P rocedure C All, remote procedure call

Simply put, the internal method calls on this machine can all be called local procedure calls,
and remote procedure calls actually refer to you locally calling a method on the remote machine .

 

Two, talk about Dubbo

 
DubboIs a Java- based RPC framework

It implements interface-oriented proxy RPC calls, and can cooperate with ZooKeeper and other components to implement service registration and discovery functions.

Features

• Distributed: that is, the application scenario is system separation , and when system A and system B need to communicate, an RPC framework is required ;
• High performance: support clustering , load balancing and fault tolerance mechanism ;
• Transparency: that is, remote method calls, just like calling local methods, with simple configuration and no API intrusion ;
• Automatic registration: ZooKeeper is used by default , providing: configuration maintenance, domain name service, distributed synchronization, group service, etc.;

 

Because it is only as an interest to introduce and understand , so I ignore many of them without too much detail ,
if you want to know more, here is a post on Ao Bing
