Architectures

What are the types of architecture ?

• Software Architecture

  • Layered Architecture

  • Data Centric Architecture

  • Object Oriented Architecture

  • Event based Architecture

• System Architecture

  • Client Server

  • P2P

What is Layered architecture ?

• In this system is divided into layers and each layers has a specific task to perform

• Each layer only communicate with layers above and below it

Adv : Easy to develop and update

Object Oriented architecture

In this , Distributed systems is build on objects

• Objects communicate with each other through method calls even in different machines

• Easy to develop and maintain

• ex: RPC,RMI

What are RPC ?

• Remote procedure call

• It is used to call function on different computer

• It is not object oriented

What are RMI?

• Remote method invocation

• It is used to call different method on an object that lives on another computer

• Its object oriented

What are data centric architecture?

• It is a design where the main focus on data

• All components interact with a central data system

• All the components follows publish/subscribe (Producer/Consumer)

What are event based architecture?

• It is a system where things are based on events

• All parts on the system wait for events and react when they happen

• It uses bus

• Data are transferred using events

• Loosly coupled systems
