Answer / rajendra
CLIENT / SERVER
An issue of client/server is that the application must be
installed on each users computer. Depending on the
complexity of the program, the environment it is written in,
and the care the developer took to package the program, this
can be as easy as creating a shortcut to an executable on a
shared network drive or it can be as hard as spending hours
installing and configuring runtime software and components
on each client computer.
Introduction to 2-Tier Architecture
2-tier architecture is used to describe client/server
systems where the client requests resources and the server
responds directly to the request, using its own resources.
This means that the server does not call on another
application in order to provide part of the service.
Introduction to 3-Tier Architecture
In 3-tier architecture, there is an intermediary level,
meaning the architecture is generally split up between:
1. A client, i.e. the computer, which requests the
resources, equipped with a user interface (usually a web
browser) for presentation purposes
2. The application server (also called middleware), whose
task it is to provide the requested resources, but by
calling on another server
3. The data server, which provides the application server
with the data it requires
Comparing both types of architecture
2-tier architecture is therefore a client-server
architecture where the server is versatile, i.e. it is
capable of directly responding to all of the client's
resource requests.
In 3-tier architecture however, the server-level
applications are remote from one another, i.e. each server
is specialised with a certain task (for example: web
server/database server). 3-tier architecture provides:
* A greater degree of flexibility
* Increased security, as security can be defined for
each service, and at each level
* Increased performance, as tasks are shared between servers
Multi-Tiered Architecture
In 3-tier architecture, each server (tier 2 and 3) performs
a specialised task (a service). A server can therefore use
services from other servers in order to provide its own
service. As a result, 3-tier architecture is potentially an
n-tiered architecture
