Factors to consider when choosing an architecture
There are several factors that should be take into account by the organization before choosing an architecture
1.cost of architecture
2.Infrastructure i.e the hardware,the applications
The cost of the client server architecture is lower than that of host based architecture.client server architecture also tend to be cheaper than host based because it places less load on the network there by requiring less network capacity
3.cost of development
The cost of developing an application system is an important factor when developing financial benefits
So developing an application software for fat server architecture is extremely complex,it cost two to three times more to develop and maintain software for client server architecture than it does for host based architecture.

Developing application software for client based architecture is usually cheaper because there are many GUI development tools

In host based networks there is only one place to update the software(main frame)while on client server networks there might be a need to update all clients and all servers
4.Scalability
This refers to the ability to decrease or increase the capacity of the computing infrastructure in response to the changing needs

The client server architecture is the most scalable because servers can be added or removed from the architecture of the processes in needs change

It is scalable because of the type of hardware used in client server architecture can be upgraded at a pace that mostly,closely matches the growth of the application

In contrast host based architecture which rely in the mainframe or severs as very expensive to
