## Why HTTP
With the rapid iteration of the Internet, more and more companies choose quick script frameworks such as nodejs, Django and rails to develop web-side applications.
+
Java is the most suitable for back-end service, which resulting in a lot of cross-language invocation requirements.
+
While HTTP and JSON are naturally suitable as cross-language standards, all languages have mature class libraries for them.
+
Although Dubbo's asynchronous long connection protocol is efficient, in scripting languages this loss of efficiency is not important.
## Why Not RESTful
Dubbox has made an attempt on the RESTful interface, but there is some difference between the REST architecture and the original RPC architecture of Dubbo.
+
The difference is that the REST architecture needs the definition of resources and we should operate the resources using the basic HTTP methods —— GET, POST, PUT, DELETE.
+
Dubbox needs to redefine the properties of the interface, which is a big burden on the original interface migration of Dubbox.
+
In contrast, RESTful is more appropriate for calls between Internet systems, and RPC is more appropriate for calls within a system, so we used JsonRPC which is more consistent with the Dubbo concept.
