The three-tier pattern / multi-tier pattern client-server

The following diagram represents a client-server interaction:

We will discuss some of the variants of client-server patterns in this section. Some of the prominent variants of client-server patterns are as follows:

• The master-slave pattern
• The peer-to-peer pattern

Let's discuss them in detail.

The master-slave pattern

The master-slave pattern is applied for designing a system if the system involves similar or identical computations that need to be performed repeatedly with separate set of inputs and context. The master-slave pattern offers support for fault tolerance and parallel computation.

The master-slave pattern is depicted in the following diagram:
