System models
In this chapter generally be described three key areas for designing distributed systems such as Physical models, Architectural models, Fundamental models, Physical models relate to the types of computers and devices that provide connectivity between them.
Architectural models refer to computationally and tasks they perform, and the interconnection network. The models used are the client-server and peer-to-peer. Fundamental models relate to solutions to the problems of distributed systems. This section explains the interaction between models, fault models, and security models.
Physical models:
Representation of hardware and network technologies used.
Baseline physical model: Software and hardware components of the computer network that coordinate the actions only through message passing.
Early distributed systems: They consist of between 10 and 100 nodes interconnected with limited Internet connectivity and services as local printers and file servers, e-mail and file transfer over the Internet.
Internet-scale distributed systems: Such systems exploit the infrastructure offered by the Internet to become truly global. They incorporate large numbers of nodes and provide distributed system services for global organizations and across organizational boundaries. These systems have high level of heterogeneity.
Contemporary distributed systems: In the above systems, nodes were desktop computers and therefore static, discrete and autonomous. The emergence of mobile computing has led to need for added capabilities such as service discovery and support for spontaneous interoperation.
The emergence of ubiquitous computing has led to a move from discrete nodes to
