Cocoa (OS X) vs Apache Dubbo: What are the differences?
Cocoa (OS X): The Cocoa frameworks consist of libraries, APIs, and runtimes that form the development layer for all of OS X. Much of Cocoa is implemented in Objective-C, an object-oriented language that is compiled to run at incredible speed, yet employs a truly dynamic runtime making it uniquely flexible. Because Objective-C is a superset of C, it is easy to mix C and even C++ into your Cocoa applications; Apache Dubbo: A high performance Java RPC framework. It is a high-performance, light weight, java based RPC framework. Dubbo offers three key functionalities, which include interface based remote call, fault tolerance & load balancing, and automatic service registration & discovery.
Cocoa (OS X) belongs to "Frameworks (Full Stack)" category of the tech stack, while Apache Dubbo can be primarily classified under "Remote Procedure Call (RPC)".
