Advantages

Distribution of data is straightforward

Makes effective use of networked systems. May require cheaper hardware

Easy to add new servers or upgrade existing servers

Disadvantages

No shared data model so sub-systems use different data organisation. data interchange may be inefficient

Redundant management in each server

No central register of names and services - it may be hard to find out what servers and services are available

A system model where the system is organised as a set of services and associated servers and clients that access and use the services

A set of servers that offer services to other sub-systems

A set of clients that call on the services offered by servers

A network that allows the clients to access these services
