Distributed computing

The message passing paradigm
The message system paradigm
1)Message-oriented Middleware
   a.Point to point message modle
   b.The publish/subscribe message modle
The distributed Objects paradigms
1)Distributed Object system/Protocals
   a.Java Remote Method Invocation(JMI)
   b.The Common Object Request Broker Achitecture(CORBA)
   c.Distributed Component Object Model(DCOM)
   d.Simple Object Access Protocal(SOAP)
The Mobile Agent Paradigm
The Client-Server Paradigm
   eg. HTTP,FTP,DNS,finger,gopher
The peer-to-peer Paradigm

Cluster Computing

Prominent components of cluster computers
1)Cluster Middleware
   a.Single system image(SSI)
   b.System Avalibity infrastructure
2)Hardware
3)Operating System Kernal/gluing layers
4)Application and subsystems

Grid Computing
Cloud Computing
